Charlotte, North Carolina-based Collins Aerospace has been selected by NASA to develop a spacewalking system for the astronauts aboard the International Space Station.

The award, which is the second under NASA’s Exploration EVA Services contract, has a base value of $97.2 million, per a Dec. 8 news release from NASA. The company has until January 2024 "to complete a critical design review and demonstrate use of the suit on Earth in a simulated space environment," according to NASA, which will then decide the option to extend the contract for testing to be conducted by April 2026.

NASA’s Johnson Space Center in Houston manages the spacesuit contract. Collins Aerospace has had a presence in Houston for 40 years, and recently cut the ribbon on a $30 million facility near the JSC.

“We look forward to obtaining another much-needed service under our contract,” says Lara Kearney, manager of the Extravehicular Activity and Human Surface Mobility Program at JSC, in the release. “By working with industry, NASA is able to continue its over 22-year legacy of maintaining a presence in low-Earth orbit.”

The current system was designed decades ago and has been used during previous space shuttle and space station missions. Collins Aerospace will work with Houston-based Axiom Space on this project, which was initially announced this summer.

"Both vendors will continue to compete for future task orders which include recurring services for station spacewalks and moonwalks beyond Artemis III," the news release reads.

Houston tech company lands exclusive spacesuit deal for NASA's mission to moon

suit up

When astronauts make a historic return to the surface of the moon, presumably 2025 or 2026, they’ll don Houston-crafted, life-protecting suits.

Houston-based Axiom Space has landed the rights to create spacesuits and supporting systems for NASA’s Artemis III mission, which will see humans back on our satellite for the first time since the legendary Apollo missions more than 50 years ago.

This award is the first for a competitive spacesuits contract, NASA notes in a press release. NASA tapped Axiom Space for a task order boasting a base value of $228.5 million. As previously reported, Axiom Space was one of two companies NASA pegged for spacesuit and supporting system development.

These new suits are pivotal, as plans for NASA’s Artemis lunar program call for not just lunar orbit, but trips to the lunar south pole and even a crewed outpost on the moon.

Axiom Space will be responsible for the design, development, qualification, certification, and production of its spacesuits and support equipment. Spacesuits will be tested for moonwalks and spacewalks.

This spacesuit contract, which will advance spacewalking capabilities in low-Earth orbit and on the Moon, is managed by the Extravehicular Activity and Human Surface Mobility Program (EHP) at Johnson Space Center.

“NASA is proud to partner with commercial industry on this historic mission that will kickstart the United States building a lasting presence on the surface of the Moon,” said Lara Kearney, manager of NASA’s Extravehicular Activity and Human Surface Mobility program. “What we learn on Artemis III and future missions on and around the Moon will pave the way for missions to Mars. Spacesuits enable us to literally take that next step.”

The first lunar mission since 1972, Artemis will be historic in myriad ways, none of least for seeing the first woman and the first person of color on the moon, as well as a testing ground for eventual Mars missions.

Artemis I is set to launch on September 19, barring any delays.

2 Houston space tech cos. celebrate major tech milestones

big wins

Two Houston aerospace companies — Intuitive Machines and Venus Aerospace — have reached testing milestones for equipment they’re developing.

Intuitive Machines recently completed the first round of “human in the loop” testing for its Moon RACER (Reusable Autonomous Crewed Exploration Rover) lunar terrain vehicle. The company conducted the test at NASA’s Johnson Space Center.

RACER is one of three lunar terrain vehicles being considered by NASA for the space agency’s Artemis initiative, which will send astronauts to the moon.

NASA says human-in-the-loop testing can reveal design flaws and technical problems, and can lead to cost-efficient improvements. In addition, it can elevate the design process from 2D to 3D modeling.

Intuitive Machines says the testing “proved invaluable.” NASA astronauts served as test subjects who provided feedback about the Moon RACER’s functionality.

The Moon RACER, featuring a rechargeable electric battery and a robotic arm, will be able to accommodate two astronauts and more than 880 pounds of cargo. It’s being designed to pull a trailer loaded with more than 1,760 pounds of cargo.

Another Houston company, Venus Aerospace, recently achieved ignition of its VDR2 rocket engine. The engine, being developed in tandem with Ohio-based Velontra — which aims to produce hypersonic planes — combines the functions of a rotating detonation rocket engine with those of a ramjet.

A rotating detonation rocket engine, which isn’t equipped with moving parts, rapidly burns fuel via a supersonic detonation wave, according to the Air Force Research Laboratory. In turn, the engine delivers high performance in a small volume, the lab says. This savings in volume can offer range, speed, and affordability benefits compared with ramjets, rockets, and gas turbines.

A ramjet is a type of “air breathing” jet engine that does not include a rotary engine, according to the SKYbrary electronic database. Instead, it uses the forward motion of the engine to compress incoming air.

A ramjet can’t function at zero airspeed, so it can’t power an aircraft during all phases of flight, according to SKYbrary. Therefore, it must be paired with another kind of propulsion, such as a rotating detonation rocket engine, to enable acceleration at a speed where the ramjet can produce thrust.

“With this successful test and ignition, Venus Aerospace has demonstrated the exceptional ability to start a [ramjet] at takeoff speed, which is revolutionary,” the company says.

Venus Aerospace plans further testing of its engine in 2025.

METRO rolls out electric shuttles for downtown Houston commuters

on a roll

The innovative METRO microtransit program will be expanding to the downtown area, the Metropolitan Transit Authority of Harris County announced on Monday.

“Microtransit is a proven solution to get more people where they need to go safely and efficiently,” Houston Mayor John Whitmire said in a statement. “Connected communities are safer communities, and bringing microtransit to Houston builds on my promise for smart, fiscally-sound infrastructure growth.”

The program started in June 2023 when the city’s nonprofit Evolve Houston partnered with the for-profit Ryde company to offer free shuttle service to residents of Second and Third Ward. The shuttles are all-electric and take riders to bus stops, medical buildings, and grocery stores. Essentially, it works as a traditional ride-share service but focuses on multiple passengers in areas where bus access may involve hazards or other obstacles. Riders access the system through the Ride Circuit app.

So far, the microtransit system has made a positive impact in the wards according to METRO. This has led to the current expansion into the downtown area. The system is not designed to replace the standard bus service, but to help riders navigate to it through areas where bus service is more difficult.

“Integrating microtransit into METRO’s public transit system demonstrates a commitment to finding innovative solutions that meet our customers where they are,” said METRO Board Chair Elizabeth Gonzalez Brock. “This on-demand service provides a flexible, easier way to reach METRO buses and rail lines and will grow ridership by solving the first- and last-mile challenges that have hindered people’s ability to choose METRO.”

The City of Houston approved a renewal of the microtransit program in July, authorizing Evolve Houston to spend $1.3 million on it. Some, like council member Letitia Plummer, have questioned whether microtransit is really the future for METRO as the service cuts lines such as the University Corridor.

However, the microtransit system serves clear and longstanding needs in Houston. Getting to and from bus stops in the city with its long blocks, spread-out communities, and fickle pedestrian ways can be difficult, especially for poor or disabled riders. While the bus and rail work fine for longer distances, shorter ones can be underserved.

Even in places like downtown where stops are plentiful, movement between them can still involve walks of a mile or more, and may not serve for short trips.

“Our microtransit service is a game-changer for connecting people, and we are thrilled to launch it in downtown Houston,” said Evolve executive director Casey Brown. “The all-electric, on-demand service complements METRO’s existing fixed-route systems while offering a new solution for short trips. This launch marks an important milestone for our service, and we look forward to introducing additional zones in the new year — improving access to public transit and local destinations.”
