Four projects intended to study potential AAM use cases and guide Michigan lawmakers as they regulate the industry have received a total of $6.25 million in funding. AAM is an umbrella term used by the FAA to denote new forms of passenger- and cargo-carrying aircraft, from drones to electric vertical takeoff and landing (eVTOL) air taxis.

The $2.6 million will be allocated to electric aircraft and charging station developer Beta Technologies. The remaining funds will be divided among drone infrastructure developer Skyports ($512,000); Traverse Connect, the economic developer for the state’s Great Traverse region ($689,500); and Michigan Central, a transportation technology campus located in Detroit ($2.45 million).

The money comes from the Michigan AAM Activation Fund, which has the combined backing of the state’s Department of Transportation (MDOT), Office of Future Mobility and Electrification (OFME), and Economic Development Corporation (MEDC). The fund aims to prepare Michigan for the arrival of AAM aircraft by coordinating state agencies.

“Advanced air mobility is an incredible economic opportunity for the state of Michigan,” said Gilchrist. “These investments create high-tech jobs, grow cutting-edge businesses, and enhance quality of life for our residents. These innovative advancements will elevate the way our companies operate, making air transportation more efficient and changing the way we move both people and cargo.”

Added Bradley Wieferich, Michigan state transportation director: “This new investment complements the state’s strategy to find safe and cost-efficient ways to capitalize on a robust network of aviation infrastructure serving Michiganders today.”

Beta will use its $2.6 million appropriation to install electric aircraft chargers statewide, including at Cherry Capital Airport (KTVC), Capital Region International Airport (KLAN), West Michigan Regional Airport (KBIV), and Willow Run Airport (KYIP).

The company is developing systems that adhere to the combined charging standard (CCS), a set of design protocols endorsed by Beta, the General Aviation Manufacturers Association (GAMA), and other manufacturers such as Archer Aviation and Boeing’s Wisk Aero. So far, Beta has about 20 chargers installed and online in the Eastern U.S., with another 50 or so in the construction or permitting process.

Skyports will use its money to launch a trio of proof-of-concept, ship-to-shore drone delivery services in the cities of Sault Ste. Marie and Detour Village, in partnership with local shipping provider Interlake Steamships. The ships will be anchored while drones arrive to pick up deliveries.

Traverse Connect, with an assortment of partners, will examine the use of drones to deliver critical medical supplies to rural areas, which typically have less access to the U.S. healthcare system. The drones will also be deployed for marine surveying, water sampling and testing, bathymetric mapping, and emergency response in the Lake Michigan area.

Michigan Central, meanwhile, has been tasked with improving Michigan’s recently announced advanced aerial innovation region, an urban campus that was opened to bring AAM companies and jobs to the state. It will also work alongside Brooklyn’s Newlab, a technology center best known for revitalizing the Brooklyn Navy Yard, to test beyond visual line of sight (BVLOS) drone use cases across building inspection, cargo delivery, and medical delivery.

“Michiganders have always been pioneers in the mobility space, and now we’re taking to the skies, finding new ways to use next-generation transportation to deliver critical resources like medical supplies and food, reinforcing international partnerships and cross-border collaboration, and so much more,” said Justine Johnson, Michigan chief mobility officer.

Dawn Aerospace, manufacturer of the Mk-II Aurora, announced that New Zealand’s Civil Aviation Authority (CAA) has granted it approval to fly at “unlimited” speeds at up to 80,000 feet in altitude. The company is permitted to fly beyond the visual line of sight (BVLOS) of a remote pilot and will not be limited to restricted airspace.

Dawn describes the Aurora as “an aircraft with the performance of a rocket.” According to the company, the aircraft is designed to be the first vehicle capable of flying to the Kármán line—which at about 100 kilometers in altitude is considered the edge of space—twice in one day.

“This unlocks the next major performance milestone for the Mk-II vehicle, namely supersonic flight,” said Stefan Powell, CEO of Dawn. “To the best of our knowledge, this would be the first privately funded [uncrewed aerial vehicle] to break the sound barrier.”

The only successful supersonic airliner, Concorde, which was developed by two now-defunct manufacturers, was retired more than two decades ago. But a new crop of companies, including Dawn and Boom Supersonic, are trying to break the sound barrier again.

Unlike Boom’s Overture, which is being developed as a passenger airline, Dawn’s Aurora is intended for space transportation.

The Mk-II first flew in 2021 and has since completed more than 50 test flights, operating under both jet and rocket power. It last flew in 2023, reaching 200 knots at an altitude of 9,000 feet. But those flights were under a more restrictive license than the one obtained by the company last week.

The goal of the firm’s upcoming campaign, which will comprise about a dozen flights between July and September, is to reach Mach 1.1—the boundary of supersonic speed—at an altitude of 70,000 feet. It hopes to fly to space twice in one day and spend about 180 seconds in microgravity.

If it achieves all objectives, the company believes it would set records for speed, altitude, and climb rate for a self-powered aircraft.

Dawn’s primary business is manufacturing propulsion systems for satellites, and it has 76 thrusters in space. But the company is now looking to enter the suborbital space.

The Aurora is a first-stage demonstrator for the company’s more robust Mk-III—a two-stage-to-orbit model that will take off from the runway and deploy a 250 kilogram satellite at the apex of its flight path.

According to Dawn, it is remotely piloted, low cost, and “rapidly reusable,” designed to fly multiple times per day and between 100 and 1,000 times over its lifespan.

Its engine uses storable, “aircraft friendly” propellants that allow the vehicle to take off without having to wait to be fueled. The engine is also carbon neutral, producing no hydrocarbons during operation.

“Room temperature storable propellants will not boil off, and carbon fiber will not suffer from microcracking, as is common in cryogenic composite tanks,” the company says on its website.

Dawn chose a winged design in order to reduce the risk of an engine malfunction, which could jeopardize the landing—and therefore reusability—of the Mk-II. It will be certified as an aircraft in New Zealand. The model takes off like a conventional aircraft, accelerating to Mach 3 speeds and bending upward into a near-vertical route. On the way down, it descends and glides horizontally back to the runway.

Dawn’s first phase of aircraft testing, conducted with the company’s jet-powered Mk-I, comprised eight hours of flight time across 47 flights. After receiving CAA approval for rocket-powered flight in March 2023, it began flying in just a few weeks.

So far, the Mk-II has made three rocket-powered flights, completed within a three-day span a little over one year ago, as part of the second phase of aircraft development, with the goal of reaching the Kármán line under certification.

According to a blog post from Powell, the current version of the vehicle has a maximum altitude of about 60,000 feet, which will require the company to develop a more powerful variant called the Mk-IIB.

“At full performance, the Mk-II will fly faster and 2.5 times higher than any prior aircraft that takes off from a runway, including the current record holder, the SR-71 Blackbird,” said Powell. “That is the power of bringing rocket performance to an aircraft platform.”

Despite being a demonstrator, Dawn plans to one day use the aircraft for Earth observation, high-speed flight research, in-space science including microgravity research, and even civil and defense applications. According to Powell, the company is already fielding interest in a commercial version of the Mk-II and will be in a “prime position” to roll one out once it reaches the Kármán Line.

In a letter to the FAA penned by John Nichols, the mayor of College Station, Texas—one of two locations where Prime Air began flying in 2022—on behalf of the city council he urged the regulator to deny a request that would more than double the service’s range. The mayor cited noise concerns from residents as the chief factor guiding the city’s position.

College Station has become a critical hub for Prime Air, which has struggled to get its drone delivery service off the ground. The city was intended to be one of two key launch markets in addition to Lockeford, California, but the latter service was shuttered in April after a less-than-stellar performance in a little more than its first year.

That leaves College Station as the sole market for Prime Air operations, and Amazon recently bolstered the service by adding on-demand delivery of prescription medications for the flu, asthma, pneumonia, and more. The e-commerce giant is also looking to bring drones to the Phoenix metro area in Arizona and has teased an international expansion to the U.K. and Italy.

Last year, Prime Air unveiled its MK30 drone, which is rangier, quieter, and more durable than its current MK27-2. To integrate the new model into its Texas fleet, the company submitted a draft supplemental environmental assessment to the FAA summarizing the MK30’s potential impacts on College Station residents.

Since the new model can fly in light rain and more extreme temperatures than the MK27-2, Amazon proposes operations 365 days per year, an increase from 260. Flights per day would increase from 200 to about 470 and would take place between 7:00 a.m. and 10:00 p.m. CT, removing an FAA restriction limiting flights to daytime hours.

Under the proposal, the company’s operating area would expand from 43.7 to 174 square miles. The expansion to 43.7 square miles happened earlier this year, when the FAA granted Amazon approval to fly its drones where its pilots cannot physically see them. Comparable waivers have been handed out to competitors such as Zipline, Alphabet’s Wing, and UPS’s Flight Forward, similarly allowing those companies to expand their service areas through remote operations.

If approved, the lighter restrictions would allow Prime Air to fly more than 170,000 operations per year in College Station with the MK30, compared to 52,000 with its current model.

Nichols said that the city is excited to be one of the few in the U.S. to host a drone delivery service. But that came with a caveat.

“While the city is supportive of Amazon Prime Air’s efforts, we do not support their request in its entirety,” Nichols wrote. “Since locating in College Station, residents in neighborhoods adjacent to Amazon Prime Air’s facility have expressed concern to the city council regarding drone noise levels, particularly during takeoff and landing, as well as in some delivery operations.”

According to Nichols, residents “have continued” to voice concerns regarding Prime Air’s planned expansion, worrying that the noise will only worsen. The mayor added that the expanded service area could extend beyond the city’s commercial zoning district, which is intended to limit commercial spillover into residential neighborhoods.

“Due to the level of concern from residents, the city would ask to delay the increase in service levels relating to the number of deliveries, as well as the expanded operation days and hours, until additional noise mitigation efforts are implemented by Amazon Prime Air,” Nichols wrote.

Nichols did offer support, however, for the introduction of the MK30, which is expected to be 40 percent quieter than its predecessor. It is unclear whether the new drone would represent sufficient “noise mitigation efforts” in the city council’s eyes, though Nichols said it would have a “positive effect” on residents’ displeasure.

The comment period for the environmental assessment closed on Friday, and the city and Prime Air will now have to wait for the FAA’s decision. Amazon is also awaiting comments and a final decision on a draft environmental assessment for its planned Arizona service.

Should the proposed expansion be rejected, it would represent yet another blow for Prime Air, which so far has not delivered on former CEO Jeff Bezos’ prognostications more than a decade ago.

In that time, competitors such as Zipline and Wing have risen to the top of the young industry—each of those firms has completed multiple hundred thousands of drone deliveries, including outside the U.S.

Prime Air’s future prospects may be bolstered by the MK30, which promises to address some of the company’s problems: namely range, excessive noise, and limitations on deliveries in inclement weather.

Amazon is not the only drone delivery provider contending with unhappy customers. Earlier this month, a Florida man was arrested for shooting down a Walmart delivery drone he said was flying over his house.

On Monday, the Air Force Research Laboratory (AFRL) announced that it and the Air Mobility Command (AMC), which provides aerial refueling and airlift services for U.S. forces worldwide, began testing a UAS traffic management (UTM) system at MacDill Air Force Base in Florida.

The system, called CLUE, or Collaborative Low-Altitude Unmanned Aircraft System Integration Effort, is designed to integrate UAS flights next to crewed aircraft above and around Air Force installations. According to the AFRL, MacDill is the first base to use a UTM system in airspace overseen by Department of Defense air traffic controllers.

“This is a significant milestone for AMC, AFRL, and the CLUE program, as the MacDill Air Traffic Control Tower and Base Defense Operations Center are first in the Air Force to operationally assess UTM capabilities,” said Phil Zaleski, manager of the AFRL CLUE program.

CLUE was born out of the AFRL’s Information Directorate as a project meant to provide “air domain awareness, situational awareness, and UTM operational capabilities for UAS operators, air traffic control [ATC] personnel, Security Forces and other stakeholders.”

The system arrived at MacDill in 2022, where initial testing focused on airspace deconfliction, communication, and security. The goal was to enable drone flights beyond the visual line of sight (BVLOS) of the operator, which are heavily scrutinized and restricted by the FAA.

Since then, the UTM platform has been developed to give air traffic controllers a three-dimensional view of UAS activity and make it possible to grant flight permissions automatically.

“Equipping airspace managers and UAS operators with a 3D operational viewing capability and additional features designed to reduce lengthy manual and advanced planning procedures will be critical to achieving real-time flight planning and mission execution,” said James Layton, chief of plans and programs at MacDill.

The system is also sensor-agnostic, meaning it integrates with an array of different sensors designed to detect, track, and identify drones, including a counter UAS system being tested at MacDill.

The Air Force in May began formally testing CLUE’s capabilities on the base, opening it to the site’s ATC tower, Defense Operations Center, and airfield management team. Personnel so far have used the system to plan the intent of UAS flights or let operators know where they are approved to fly a drone, for example.

Operators ask CLUE for the all clear to fly, and their request is either approved or denied by the control tower. Once permission is granted, they can fly within a bounded area. CLUE feeds the operators information about the airspace and other nearby aircraft, helping them stay within the approved zone while avoiding other drones.

The UTM system has also been installed at Eglin AFB’s Duke Field (KEGI) in Florida, where the AFRL conducted a demonstration of its capabilities in 2023. There, CLUE will begin by integrating flights of small UAS (weighing less than 70 pounds) before moving to larger designs, including electric vertical takeoff and landing (eVTOL) air taxis such as Joby Aviation’s five-seat S4.

Joby, partnering with AFWERX, the Air Force’s innovation arm, earlier this year committed to deliver two air taxis to MacDill and has also shipped a prototype aircraft to Edwards AFB in California.

MacDill in May also hosted flights of a KC-135 Stratotanker equipped with an autonomous flight system from developer Merlin Labs, which is designed to one day enable fully remote flights. That technology, as well as systems from fellow AFWERX collaborators Xwing and Reliable Robotics, could one day be integrated into the CLUE UTM.

AFWERX and the AFRL are not the only government entities studying UTM systems. The Air Force is working with NASA to build a digital operations center for drones and electric air taxis nationwide and is collaborating with the FAA to integrate novel and uncrewed aircraft with air traffic control and other systems within the national airspace.

On Friday, Southwest and Archer Aviation, manufacturer of the Midnight electric vertical takeoff and landing (eVTOL) air taxi, signed a memorandum of understanding (MOU) to develop a network of routes connecting Southwest terminals at California airports.

The airline is the state’s largest air carrier and owns key hubs in Los Angeles, San Diego, Sacramento, and the San Francisco Bay Area, where Archer recently announced plans to construct eVOL infrastructure, such as takeoff and landing vertiports, at five airports.

Archer’s flagship aircraft, which takes off and lands like a helicopter but flies on fixed wings like an airplane, is designed for a pilot to fly as many as four passengers on 20 to 50 sm (17 to 43 nm) air taxi routes, cruising at up to 150 mph (130 knots).

As soon as next year, it will begin ferrying customers to and from airports at a price the manufacturer claims will be cost-competitive with ground-based rideshare services such as Uber or Lyft.

“Integrating Archer’s electric aircraft into the travel journey potentially gives us an innovative opportunity to enhance the experience of flying Southwest,” said Paul Cullen, vice president of real estate for the airline.

Cullen also left the door open for an expansion of Southwest’s air taxi service to locations in other states.

Added Dee Dee Meyers, senior adviser to California Governor Gavin Newson and director of the Governor’s Office of Business and Economic Development: “This initiative is designed to help revolutionize clean transportation with zero-direct emission and affordable options, enhancing the passenger experience, and supporting California’s climate action goals.”

The agreement with Southwest builds on Archer’s existing relationship with United Airlines, which in 2021 agreed to purchase 100 Midnight air taxis for an estimated $1 billion. Under that agreement, Archer will develop a software platform, mobile booking platform, and vertiport integration technology for a commercial service operated by United.

Delta Air Lines, the third major U.S. carrier with plans to launch an air taxi network, is working with Archer competitor Joby Aviation.

In addition, Archer in June signed a deal with Signature Aviation that would give it access to more than 200 FBOs, including those at New York Liberty International Airport (KEWR), Chicago O’Hare International Airport (KORD), and other airports the company intends to serve. The manufacturer also has an agreement with FBO network operator Atlantic Aviation to electrify Atlantic terminals in New York, Los Angeles, Miami, and San Francisco.

“With Archer’s Midnight aircraft, passengers will be able to fly above traffic to get to the airport faster,” said Nikhil Goel, chief commercial officer of Archer. “Southwest customers could someday complete door-to-door trips like Santa Monica [California] to Napa in less than three hours.”

Archer and Southwest will begin by developing a concept of operations for Midnight out of Southwest terminals, partnering with airline employees and union groups such as the Southwest Airlines Pilot Association (SWAPA).

The companies “plan to collaborate over the next few years as eVTOLs take flight,” which does not commit them to a 2025 or 2026 launch. Archer, Joby, and other eVTOL manufacturers such as Beta Technologies and Overair intend to enter commercial service during that time frame.

Adding Southwest as a partner could be key for Archer when considering the activities of its competitor overseas.

Both firms plan to fly in the United Arab Emirates, including the cities of Abu Dhabi and Dubai. In February, however, Joby signed what it describes as an exclusive six-year deal with Dubai’s Road and Transport Authority, giving it the sole right to operate an air taxi service in the emirate. Archer CEO Adam Goldstein has disputed the exclusivity of the agreement, saying it will have no impact on the company’s plans.

That dynamic has not yet played out in the U.S.—both companies plan to fly in New York, for example. But if Joby intends to replicate the strategy of gaining an edge over competitors with exclusive deals, partnerships such as that with Southwest become more important.

Notably, the companies have also butt heads on eVTOL infrastructure. Each is pushing for a different electric aircraft charging system to become the industry standard, similar to how Elon Musk fought for Tesla’s North American Charging Standard to supplant the widely accepted Combined Charging Standard (CCS) for electric ground vehicles (a fight Tesla ultimately would win).

Similarly, Joby wants its Global Electric Aviation Charging System (GEACS) to replace a modified version of the CSS supported by Archer, Beta, and others, which could throw a wrench into their FBO electrification plans.

Among eVTOL manufacturers, Archer and Joby are the closest to being able to fly in the U.S. Each has achieved a full transition flight using a prototype air taxi and expects to begin the critical for-credit phase of FAA certification in the coming months.

In addition, both are qualified to perform eVTOL maintenance and repairs and are in the process of training an initial group of pilots to fly their respective aircraft.

The goal is for those activities to be complete in time for a 2025 launch. Whether Southwest will be a part of that occasion remains to be seen.

On June 24, the firm’s “first-of-its-kind” hydrogen-electric, vertical takeoff and landing (hVTOL) demonstrator completed a 532 sm (462 nm) flight—about the distance between San Francisco and San Diego—above Marina, California, home to the Joby’s test facility and pilot production line. The aircraft landed with more than 10 percent of its hydrogen fuel remaining, with water the only byproduct of the flight.

Joby believes the test, which included a vertical take off and landing, represented the first forward flight for a liquid hydrogen-powered eVTOL aircraft. The company said hydrogen is a key piece of its future plans.

“We’re excited to now be building a technology stack that could redefine regional travel using hydrogen-electric aircraft,” said JoeBen Bevirt, founder and CEO of Joby. “Imagine being able to fly from San Francisco to San Diego, Boston to Baltimore, or Nashville to New Orleans, without the need to go to an airport and with no emissions except water. That world is closer than ever.”

The development signals a shift in Joby’s stated business philosophy, which before Thursday was centered around flying urban air mobility (UAM) routes within cities.

In a blog post penned by Bevirt and Raffaele Russo, business manager for new technologies at Joby, the company’s top brass said regional air mobility (RAM) is also on the agenda. The firm has alluded to a regional service before, but Thursday’s developments appear to confirm that one is in the works.

“Although the specific energy of batteries is improving, their weight will continue to limit the application of electric aircraft to short-distance travel,” the blog post reads. “To serve regional markets, we plan to use hydrogen to increase the potential range and payload of electric aircraft.”

Joby’s hydrogen-electric program builds on the technology developed by its subsidiary H2FLY, acquired in secret in 2021.

The manufacturer built the hydrogen-electric demonstrator by modifying one of its battery-electric aircraft, which has already flown more than 25,000 miles, with a hydrogen fuel tank capable of storing up to 40 kilograms of liquid, supercooled hydrogen. It includes a smaller battery cell, which provides extra power during takeoff and landing.

The design employs the same airframe and overall architecture as its battery-electric counterpart. It will use the same takeoff and landing sites and operations team, as well as ElevateOS—a proprietary, Uber-like software suite unveiled in June.

ElevateOS comprises a pilot app, rider app, operations suite, and matching system that connects riders with aircraft based on departure time, arrival time, and location. It includes an integration with the Uber app, allowing Uber customers to book Joby flights and vice versa.

The hydrogen-powered model also includes the H2F-175 hydrogen fuel cell, built by H2FLY, which produces electricity and heat with water as the sole byproduct. The fuel cell powers the aircraft’s six electric motors, which feed into tilting propellers that assist in both hover and forward flight, and charges the batteries while they are deactivated in cruise mode.

The technology was deployed about one year ago during a milestone H2FLY flight, which Joby claims was the first crewed flight of a hydrogen-electric aircraft with a runway takeoff.

According to Joby’s estimate, the hydrogen-electric model will have a greater payload than a battery-electric design or an aircraft using an equivalent amount of jet fuel.

Bevirt is also bullish on hydrogen production, pointing to the U.S. Department of Energy’s $7 billion investment in clean “hydrogen hubs.” He noted that hydrogen can be produced using a variety of low- or zero-emission sources such as wind or water power, which could help the aviation industry meet commitments to eliminate emissions by 2050.

“We recognize that broadly commercializing hydrogen will require doing the hard miles on regulation and infrastructure, along with fuel storage and distribution, but we have demonstrated that regional hydrogen-electric flight is possible today,” Bevirt and Russo wrote in Thursday’s blog post.

Bevirt said the bulk of the work Joby has done to certify its flagship, battery-electric air taxi will carry over to commercializing a hydrogen-electric variant. The company’s hydrogen-electric activities are supported by Agility Prime, the vertical lift technology division of the U.S. Air Force innovation arm, AFWERX.

“Agility Prime has been very supportive of hydrogen-powered aircraft development and testing as it aligns with the program’s goals to advance transformative vertical lift technologies and broader Department of Defense operational energy goals of energy substitution and diversification, and energy demand reduction,” said Jacob Wilson, acting branch chief of Agility Prime.

Joby is also collaborating with AFWERX’s Autonomy Prime division, which, as the name implies, develops self-flying aircraft.

The company in June acquired autonomous flight company Xwing for an undisclosed fee and intends to build a self-flying version of its flagship air taxi in the future, using Xwing’s Superpilot software. U.S. competitor Wisk Aero and Chinese eVTOL manufacturer EHang are among the handful of firms looking to fly autonomous air taxis at launch.

Joby aims to launch commercial operations with its flagship battery-electric air taxi in 2025, in partnership with Delta Air Lines. New York and Los Angeles are slated as the company’s first U.S. markets.

The aircraft is designed for a pilot to fly as many as four passengers on trips up to 100 sm (87 nm), cruising at 200 mph (174 knots). In the U.S., Joby will operate the model itself.

On Saturday, after 378 days of solitude, crewmembers Anca Selariu, Nathan Jones, Kelly Haston, and Ross Brockwell emerged from Mars Dune Alpha: a 1,700-square-foot simulated Mars habitat part of NASA’s Crew Health and Performance Exploration Analog (CHAPEA) program. The yearlong simulation was the first of three planned exercises with human volunteers.

“Hello. It’s actually just so wonderful to be able to say hello to you all,” said Haston, CHAPEA commander, as cameras captured the moment she stepped outside the 3D-printed habitat.

The goal of CHAPEA is to provide NASA data on the effects of long-duration habitation of Mars by putting the crew through the throes of life on the Red Planet: isolation, equipment failures, limited resources, and plenty of work. Selariu, Jones, Haston, and Brockwell entered the simulator on June 25, 2023.

The habitat includes 3D-printed spaces for cooking, medical, recreation, fitness, work, and growing crops, as well as private quarters and bathrooms for each crewmember. Volunteers tested out each of these amenities, grew and ate crops like tomatoes and peppers, and performed simulated “Marswalks,” collecting data on their physical and mental health.

“We cannot live, dream, create, or explore on any significant time frame if we don’t live these principles, but if we do, we can achieve and sustain amazing and inspiring things like exploring other worlds,” Brockwell said Saturday during a press conference.

In conjunction with Artemis missions to the moon, CHAPEA is helping prepare NASA for flights to Mars and beyond without crews having to leave Earth. According to the space agency, 3D printing could become a unique tool in its arsenal when the time comes.

“Future space exploration settlements have the potential to be 3D printed with additive construction technology to eliminate the need to launch large quantities of building materials on multiple flights, which is cost prohibitive,” the agency says on the Mars Dune Alpha webpage.

In February, NASA put out the call for the next group of CHAPEA volunteers, who are scheduled to enter the habitat in spring 2025.

“Mars is our goal,” said Stephen Koerner, deputy director of NASA’s Johnson Space Center, during the media briefing Saturday. “As global interests and capabilities in space exploration continue to expand, America is poised to lead.”

For the public, those were the first words heard from NASA astronauts Butch Wilmore and Suni Williams—the crew of the space agency’s Boeing Crew Flight Test (CFT)—since they arrived at the orbital laboratory more than one month ago for an intended eight-day stay.

The Earth-to-orbit call between crew and NASA command was live streamed on the agency’s website. The event answered appeals from members of the media, made during a previous press conference, to see the astronauts on camera as concerns with Boeing’s CST-100 Starliner—which brought them to the ISS—continue to linger.

The spacecraft is contending with two key problems: helium leaks and deactivated or underperforming thrusters. The issues are concentrated within the spacecraft’s service module, which aids in maneuvers such as docking and undocking with the ISS.

NASA and Boeing have indicated that Starliner has more than enough helium to make it home but are continuing to assess the root cause of the leaks. During a hot fire test after docking, four out of the five affected thrusters performed as expected. The fifth was deactivated for the remainder of the mission.

Williams and Wilmore recounted their trip to the space station and the moment they realized that Starliner’s thrusters were not firing at full power. They also sang the spacecraft’s praises, with Wilmore even saying he was tempted to award his first perfect rating for its handling performance.

Separately, NASA and Boeing representatives held a press conference to provide the latest on ongoing ground thruster testing at White Sands Test Facility in New Mexico. Officials again did not provide a firm return date for Wilmore and Williams. But Steve Stich, manager of NASA’s Commercial Crew program, estimated that testing could wrap up by the end of the month, after which point teams will iron out a timeline.

Engineers hope to conduct as many evaluations as possible while the semireusable spacecraft, designed to survive 10 missions, is in orbit. Starliner’s service module, the expendable component of the spacecraft, will be jettisoned and lost as it reenters Earth’s atmosphere.

Astronauts Phone Home

Williams and Wilmore on Wednesday made their long-awaited first appearance on camera since arriving at the ISS on June 6, recounting the CFT’s progress so far.

“Launch was spectacular,” Wilmore said, adding that the spacecraft performed “unbelievably well” during operational capability checks.

However, on the second day of their journey to the ISS, the astronauts could tell something was amiss. As Starliner approached the orbital lab, a total of five reaction control system (RCS) thrusters on its service module either turned off or did not fire at intended strength. Williams and Wilmore commandeered the capsule manually for about one hour as teams on the ground assessed the issue.

“From that point on, you could tell that the thrust was degraded,” Wilmore said. “But it was still impressive.”

Even with less-than-optimal performance, the thrusters completed what Wilmore described as a perfect maneuver as they navigated the final 10 meters to dock Starliner with the space station.

According to Williams, the astronauts talk with mission crews once per week to share and analyze the data they’ve collected. She highlighted the capsule’s ability to serve as a “safe haven” in the event of an ISS evacuation—a role it fulfilled last month after a Russian satellite broke up in orbit.

“We are having a great time here on the ISS,” said Williams. “I’m not complaining, Butch isn’t complaining, that we’re here for a couple extra weeks.”

One question NASA and Boeing have received is whether Starliner could bring Williams and Wilmore home right now. Officials insist it could, but only in an emergency situation that would require the ISS to be evacuated. The astronauts were asked about their confidence level in that scenario.

“I feel confident that, if we had to—if there was a problem with the International Space Station—we could get in the spacecraft and undock, talk with our team, and figure out the best way to come home,” said Williams.

She later added, “I have a real good feeling in my heart that the spacecraft will bring us home no problem.”

Wilmore said he and his crewmate “trust the tests we are doing are the right ones we need to do to get us the right answers, to give us the data we need to come back,” adding that they are “absolutely ready” for a return based on current engineering data.

NASA could send a SpaceX Crew Dragon capsule—which has completed all eight ISS Commercial Crew rotation missions to date—to retrieve the astronauts should Starliner’s issues persist. On Wednesday, Stich said the space agency has not yet opened those discussions with SpaceX, though he did not rule out the possibility.

The astronauts also described their view of Hurricane Beryl from space, saying that their families—who live in Texas and were in the storm’s path—are doing well. Wilmore said he is “90 percent sure” he could see the storm forming off the West coast of Africa days before it was named.

The 20-minute call concluded with some zero-gravity backflips by Williams and a big, smiling thumbs-up from Wilmore.

Stich and Mark Nappi, vice president and general manager of Boeing’s Commercial Crew program, addressed the media following the astronauts’ remarks.

According to Stich, Starliner will need to undock before mid-August, when SpaceX’s Crew-8 team swaps with the incoming Crew-9. Williams and Wilmore will need to return a few days before the Crew-9 launch window opens. Starliner remains a “go” for return in an emergency scenario, officials said. But they prefer to wait until ground testing is complete before attempting a by-the-books return,

Stich estimated that hot fire testing at White Sands could “optimistically” wrap up by the end of July, though it could be extended. Teams are working toward a nominal return flight readiness review, standard for crew rotation missions, that would give the green light to finish the mission as planned. 

Should more time be needed, NASA is in the process of approving a 45-day extension of the CFT, which is contingent on the health of Starliner’s batteries. According to Stich, those systems have shown no sign of wear and tear.

The goal of the test campaign is to recreate the firing pattern of one of Starliner’s faulty thrusters using an identical thruster—designed for a future mission—on the ground. Hot fire testing began on July 3, but Stich said crews have so far been unable to achieve the temperatures experienced by the thruster in orbit. Engineers believe the unusual firing pattern could be due to excess heat.

Teams will then attempt to predict how the thrusters might behave as Starliner undocks and flies home. Based on their learnings, they could modify the spacecraft’s flight path, deactivate certain thrusters, or fire them at different rates. Williams and Wilmore are capable of piloting Starliner manually if issues arise.

At the same time, Stich said White Sands personnel are evaluating the service module for Starliner’s inaugural crew rotation mission, Starliner-1, scheduled for February. The current service module has contended with a series of helium leaks, for which crews are attempting to uncover the root cause. Starliner-1’s service module won’t be redesigned, but Nappi said future models could incorporate changes based on the testing at White Sands.

The Outlook

Extended ISS stays are not necessarily uncommon, and the space station is designed to accommodate crew for months at a time if needed.

NASA astronaut Frank Rubio, for example, set a U.S. spaceflight record when his planned six-month mission was nearly doubled to 371 consecutive days aboard the orbital laboratory. Unlike Starliner, the Russian Soyuz capsule that ferried Rubio to the ISS was quickly ruled out as an emergency return vehicle, lending credence to the idea that Boeing’s issues are less severe.

However, NASA and Boeing face the added pressure of certification after close to a decade of delays to the Starliner program. In a prior press conference, Stich acknowledged that NASA and Boeing “understand it’s going to take a little bit longer” to certify Starliner than originally planned.

On Wednesday, the Commercial Crew manager said teams will decide between Starliner-1 or SpaceX Dragon’s Crew-10—which are booked for the same February launch window—once the CFT ends and postflight analysis is complete. The longer that takes, he said, the more likely it is that SpaceX will take over the mission.

Nappi agreed with that assessment, citing the need to understand and fix Starliner’s helium leaks as the biggest obstacle to certification.

NASA and Boeing said Wilmore and Williams will make one more Earth-to-orbit call before they depart the ISS, with more details to come.

Munich-based manufacturer Vaeridion on Saturday opened its electric battery development lab at the Bosch Collaboration Campus in Holzkirchen, Germany. The site, located in the Munich suburbs, grants Vaeridion access to hardware and services from Bosch General Aviation Technology—the GA arm of the multinational engineering firm—and ITK Engineering, which Bosch acquired in 2016.

Vaeridion will use the campus to develop powertrains, battery models, and cybersecurity compliance for its digital systems, as well as test and integrate its proprietary high-voltage batteries for its flagship Microliner. The facility will run the gamut of battery manufacturing steps, from individual cells to fully integrated modules.

In addition to Vaeridion co-founders Ivor van Dartel and Sebastian Seemann, the opening of the center was attended by Bavarian State Government Minister Florian Herrmann and Holzkirchen Mayor Christoph Shmid.

“Bavaria is proud of its vibrant startup scene, which benefits from the excellent ecosystem of science, research and technology-passionate policies,” said Herrmann. “Sustainable e-mobility is a future topic with a global market—the development of a battery-powered microliner is therefore a brilliant idea.”

According to a 2018 study, more than 80 percent of Germany’s population lives within 20 kilometers of a regional airfield. Vaeridion’s flagship Microliner is designed to connect those sites and provide a new option for underserved regions, saving customers multiple hours per trip, the company claims. It can also take off and land at large commercial airports.

The aircraft’s glider-inspired wing features a high aspect ratio, minimizing drag in cruise and producing a high glide ratio. The batteries, which can be charged in about 45 minutes, are integrated there rather than in the fuselage to optimize the aircraft’s weight and travel distance, Vaeridion says. The manufacturer claims its design flies with the lowest energy consumption for an aircraft seating up to nine passengers plus crew for distances up to 500 km (310 miles).

Working with Aircraft Design Certification GmbH, which owns design organization approval (DOA) from the European Union Aviation Safety Agency (EASA), Vaeridion hopes to certify the model as a GA aircraft before 2030.

By that year, the manufacturer intends to introduce the Microliner on commercial routes in Denmark in partnership with Copenhagen AirTaxi and Copenhagen Helicopter, both based out of Roskilde Airport (EKRK) in Copenhagen. The companies believe the design will be part of a digital platform that allows customers to plan, book, and pay for flights in one place.

“The new green aircraft type requires significantly shorter takeoff and landing distances than traditional aircraft, which allows the use of smaller airfields that are no longer utilized for commercial routes,” said Martin Winther Andersen, CEO of Copenhagen Helicopter. “These routes were abandoned as aircraft types gradually became larger. The Microliner can change that, allowing us to create a dense network of domestic routes again.”

In addition, Belgium and Netherlands-based operator ASL Group plans to utilize the aircraft for short-haul business routes. Aero-Dienst, the operation and maintenance provider for European automobile association ADAC’s fleet of ambulance helicopters, intends to deploy it for aircraft maintenance and air ambulance services.

The company on Tuesday announced a partnership with California-based vertiport developer and operator Skyway Technologies to install eVTOL hubs in South Florida and Puerto Rico. The partners plan to release more information on locations and routes in those markets in the coming months, with plans to launch service in 2026.

“Our partnership with UrbanLink is advancing the industry towards launching operations in the United States,” said Clifford Cruz, CEO of Skyway.

Similar to a heliport, a vertiport allows an eVTOL aircraft to take off and land vertically, with additional infrastructure for electric charging. In addition to design and operation, Skyway provides vertiport services such as air traffic management and mission planning.

The partnership is UrbanLink’s second in as many months following an agreement with Texas-based Ferrovial Vertiports to build a network of hubs in South Florida and the Los Angeles metro area.

Both collaborations are intended to set the stage for Lilium Jet operations across networks linking the takeoff and landing locations. The sites are also meant to serve “the broader [advanced air mobility (AAM)] industry,” UrbanLink says.

“In order to finance and build the vertiports needed to support the AAM industry, it is crucial to have multiple partners,” said Ed Wegel, who founded UrbanLink earlier this year and serves as chairman. “We are impressed with Skyway’s understanding of our business and their commitment to delivering well-designed, safe, and efficient vertiports in the U.S. and Caribbean.”

The operator is eyeing a 2026 U.S. commercial launch, which is in line with Lilium’s projections for when its flagship Lilium Jet will be ready for service.

The manufacturer is so far the only company to receive certification bases from both the FAA and European Union Aviation Safety Agency (EASA) for a commercial eVTOL design. It intends to fly on both sides of the Atlantic, as well as in the Middle East.

The Lilium Jet is expected to cruise at 162 knots on city-to-city trips spanning 25 to 125 sm (22 to 109 nm). It uses a propulsion system seldom seen on eVTOL designs, with a pair of electric motors feeding 10 independent battery packs that power 36 electric ducted fans embedded in the aircraft’s fixed wings. These allow it to hover and take off vertically like a helicopter, with minimal noise production or impact on cruise performance, Lilium says.

By contrast, manufacturers such as Archer Aviation and Joby Aviation employ tilting rotors and propellers that aid in both vertical and forward flight.

The unique propulsion system underwent initial testing in June ahead of the Lilium Jet’s first crewed flight, expected later this year. The manufacturer began building its first production prototype aircraft, which will be used to validate the design with regulators, in December.

Since partnering in May, Lilium and UrbanLink have moved quickly to target eVTOL jet operations in South Florida—which is poised to be Lilium’s U.S. base of operations—Los Angeles, Southern California, and Puerto Rico. Announcements for additional locations are on the horizon, they said Tuesday.
