SpaceX’s mega Starship rocket completed its first full test flight Thursday, returning to Earth without exploding after blasting off from Texas.

It was the fourth launch of the world’s biggest and most powerful rocket, standing nearly 400 feet (121 meters) tall. The three previous flight demos ended in explosions. This time, the rocket and the spacecraft managed to splash down in a controlled fashion, making the hourlong flight the longest and most successful yet.

“Despite loss of many tiles and a damaged flap, Starship made it all the way to a soft landing in the ocean!” SpaceX CEO Elon Musk said via X.

Starship was empty as it soared above the Gulf of Mexico and headed east on a flight to the Indian Ocean. Within minutes, the first-stage booster separated from the spacecraft and splashed into the gulf precisely as planned, after firing its engines.

The spacecraft reached an altitude of nearly 130 miles (211 kilometers), traveling at more 16,000 mph (26,000 kph), before beginning its descent. Live views showed parts of the spacecraft breaking away during the intense heat of reentry, but a cracked camera lens obscured the images.

The spacecraft remained intact enough to transmit data all the way to its targeted splashdown site in the Indian Ocean.

It was a critical milestone in the company’s plan to eventually reuse the rocket that NASA and Musk are counting on to get humanity to the moon and then Mars.

“What a show it has been,” SpaceX launch commentator Kate Tice said from Mission Control at company headquarters in California.

SpaceX came close to avoiding explosions in March, but lost contact with the spacecraft as it careened out of space and blew up short of its goal. The booster also ruptured in flight, a quarter-mile above the gulf.

Last year’s two test flights ended in explosions shortly after blasting off from the southern tip of Texas near the Mexican border. The first one cratered the pad at Boca Chica Beach and hurled debris for thousands of feet (meters).

SpaceX upgraded the software and made some rocket-flyback changes to improve the odds. The Federal Aviation Administration signed off Tuesday on this fourth demo, saying all safety requirements had been met.

Starship is designed to be fully reusable. That’s why SpaceX wants to control the booster’s entry into the gulf and the spacecraft’s descent into the Indian Ocean — it’s intended as practice for planned future landings. Nothing is being recovered from Thursday’s flight.

NASA has ordered a pair of Starships for two moon-landing missions by astronauts, on tap for later this decade. Each moon crew will rely on NASA’s own rocket and capsule to leave Earth, but meet up with Starship in lunar orbit for the ride down to the surface.

SpaceX already is selling tourist trips around the moon. The first private lunar customer, a Japanese tycoon, pulled out of the trip with his entourage last week, citing the oft-delayed schedule.

SpaceX’s founder and CEO has grander plans: Musk envisions fleets of Starships launching people and the infrastructure necessary to build a city on Mars.

SpaceX's mega rocket launch from Texas base provides mixed results

50-minute flight

SpaceX came close to completing an hourlong test flight of its mega rocket on its third try Thursday, but the spacecraft was lost as it descended back to Earth.

The company said it lost contact with Starship as it neared its goal, a splashdown in the Indian Ocean. The first-stage booster also ended up in pieces, breaking apart much earlier in the flight over the Gulf of Mexico after launching from the southern tip of Texas near the Mexican border.

“The ship has been lost. So no splashdown today,” said SpaceX’s Dan Huot. “But again, it’s incredible to see how much further we got this time around.”

Two test flights last year both ended in explosions minutes after liftoff. By surviving for close to 50 minutes this time, Thursday's effort was considered a win by not only SpaceX's Elon Musk, but NASA as well as Starship soared higher and farther than ever before. The space agency is counting on Starship to land its astronauts on the moon in another few years.

The nearly 400-foot (121-meter) Starship, the biggest and most powerful rocket ever built, headed out over the Gulf of Mexico after liftoff Thursday morning, flying east. Spectators crowded the nearby beaches in South Padre Island and Mexico.

A few minutes later, the booster separated seamlessly from the spaceship, but broke apart 1,500 feet (462 meters) above the gulf, instead of plummeting into the water intact. By then, the spacecraft was well to the east and continuing upward, with no people or satellites on board.

Starship reached an altitude of about 145 miles (233 kilometers) as it coasted across the Atlantic and South Africa, before approaching the Indian Ocean. But 49 minutes into the flight — with just 15 minutes remaining — all contact was lost and the spacecraft presumably broke apart.

At that point, it was 40 miles (65 kilometers) high and traveling around 16,000 mph (25,700 kph).

SpaceX's Elon Musk had just congratulated his team a little earlier. “SpaceX has come a long way,” he said via X, formerly called Twitter. The rocket company was founded exactly 22 years ago Thursday.

NASA watched with keen interest: The space agency needs Starship to succeed in order to land astronauts on the moon in the next two or so years. This new crop of moonwalkers — the first since last century’s Apollo program — will descend to the lunar surface in a Starship after transferring from NASA's Orion capsule in lunar orbit.

NASA Administrator Bill Nelson quickly congratulated SpaceX on what he called a successful test flight as part of the space agency's Artemis moon-landing program.

The stainless steel, bullet-shaped spacecraft launched atop a first-stage booster known as the Super Heavy. Both the booster and the spacecraft are designed to be reusable, although they were never meant to be salvaged Thursday.

On Starship’s inaugural launch last April, several of the booster’s 33 methane-fueled engines failed and the booster did not separate from the spacecraft, causing the entire vehicle to explode and crash into the gulf four minutes after liftoff.

SpaceX managed to double the length of the flight during November’s trial run. While all 33 engines fired and the booster peeled away as planned, the flight ended in a pair of explosions, first the booster and then the spacecraft.

The Federal Aviation Administration reviewed all the corrections made to Starship, before signing off on Thursday’s launch. The FAA said after the flight that it would again investigate what happened. As during the second flight, all 33 booster engines performed well during ascent, according to SpaceX.

Initially, SpaceX plans to use the mammoth rockets to launch the company’s Starlink internet satellites, as well as other spacecraft. Test pilots would follow to orbit, before the company flies wealthy clients around the moon and back. Musk considers the moon a stepping stone to Mars, his ultimate quest.

NASA is insisting that an empty Starship land successfully on the moon, before future moonwalkers climb aboard. The space agency is targeting the end of 2026 for the first moon landing crew under the Artemis program, named after the mythological twin sister of Apollo.

Venus Aerospace closes $91M funding round to scale hypersonic engine

flight funding

Houston-based Venus Aerospace has closed a $91 million Series B round and plans to scale the production of its hypersonic engine.

The round was led by Houston-based Mercury Fund with participation from Lockheed Martin Ventures, MESH, PEAK6, Draper Associates, Starboard Star Venture Capital, Green Sands Equity and other investors, according to a news release.

The investment comes about a year after Venus completed the first U.S. flight test of its high-thrust rotating detonation rocket engine (RDRE). The engine is expected to enable vehicles to travel four to six times the speed of sound from a conventional runway and is about 15 percent more efficient than traditional alternatives, according to the company.

Venus Aerospace says the latest round of funding will allow it to move the RDRE from demonstration to deployment and meet customer requirements for the near-term defense and space industries. The company says that the reusable RDRE is designed with a "common propulsion architecture" that can work for multiple industries and mission types.

“This financing marks an important step in moving Venus from breakthrough demonstration to scaled capability,” Sassie Duggleby, co-founder and CEO, said in the news release. “Our customers need propulsion systems that go farther, can be produced reliably and are built on supply chains they can trust. We are advancing that capability with American engineering and manufacturing talent to strengthen U.S. defense, expand space access and support the future of high-speed flight.”

Venus Aerospace raised a $20 million Series A in 2022, led by Wyoming-based Prime Movers Lab. At the time, the company said it would put the funding toward three main technologies: a next-generation rocket engine, aircraft shape and leading-edge cooling system.

The company also picked up an investment from Lockheed Martin Ventures, the investment arm of aerospace and defense contractor Lockheed Martin, in November 2025—in addition to funding from other investors over the years.

“Since our initial investment, Venus has progressed very quickly in its technology development," Chris Moran, vice president and general manager of Lockheed Martin Ventures, added in the release. "Our reinvestment in Venus recognizes Venus’ accomplishments to date and focus on speed to manufacture, cost management and reduction of supply chain constraints. Venus is working effectively to position its propulsion system for the production scale required by defense programs.”

"Venus is exactly the kind of company Houston capital should be backing," Blair Garrou, co-founder and managing partner at Mercury Fund, added in the release. "It combines multiple frontier technologies, domestic manufacturing and clear commercial and national security relevance. We believe this team is positioned to lead an important new chapter in defense and space, and we are proud to support a company building breakthrough technology here in Texas."

Venus Aerospace and Houston clean tech startup Vaulted Deep were named to the World Economic Forum's Technology Pioneers community earlier this summer. Read more here.

Intuitive Machines lands $148M as part of NASA Moon Base funding

to the moon

Houston-based Intuitive Machines has been awarded $148.3 million to deliver its Nova-C lander to the moon by 2028. The funding is part of $600 million that NASA recently awarded to three companies as part of the agency’s Moon Base Program.

The contracts aim to support sustained human presence and commercial operations on the Moon. Austin-based Firefly Aerospace was awarded $144.2 million by NASA for one mission and Pittsburgh-based Astrobotic netted $297.9 million for two lunar landings. Intuitive Machine's award is the company's sixth task order under NASA's Commercial Lunar Payload Services (CLPS) program.

“We’re building a proving ground for Moon Base operations,” Ryan Stephan, NASA’s Moon Base acting director of cargo landers, said in a news release. “Accelerating our Moon mission ordering cadence and launch opportunities enable us to move quickly to learn, iterate, and improve.”

Under the latest task order, Intuitie Machines will deliver three scientific and operational payloads to the moon, which include a:

Linear Energy Transfer Spectrometer (LETS) radiation monitor to gather critical environmental safety data
Advanced stereo cameras to analyze surface-plume interactions (SCALPSS)
Laser retroreflector array (LRA) for precise cislunar positioning

The funding breakdown includes a $68.6 million base contract and a $79.7 million performance incentive for Intuitive Machines.

The company says the funding will allow it to create a standardized and repeatable "lunar utility pipeline" for delivering cargo to the moon.

"We are shifting the paradigm from custom aerospace engineering to commercial mass production of lunar infrastructure," Steve Altemus, CEO of Intuitive Machines, said in a separate news release. "Our flight-proven Nova-C platform allows us to build, test, and deploy multiple landers in parallel using Industry 4.0-powered manufacturing. This contract directly advances our core mission to provide persistent, reliable, and commercial baseline of transport, connectivity, and operations that allows our customers to stay longer and achieve more on the Moon."

NASA also shared that it is exploring plans to send PROMISE, a rover based on the Mars Perseverance and Curiosity rovers, to the moon and it plans to seek proposals for additional lunar lander missions, technology demonstrations, a communications and navigation satellite network, and new science payloads to support its lunar outpost. NASA is developing its Moon Base near the lunar South Pole. The agency expects it to come to fruition sometime after 2032.

Intuitive Machines had received its last CLPS award for $180.4 million in March 2026. It will be the first mission to utilize the company's larger cargo lunar lander, Nova-D. The company was also recently awarded a $1 million grant from Maryland Gov. Wes Moore to expand its robotics operations in the state.

UT team develops wearable technology for atmospheric water harvesting

In The Air

Engineers at the University of Texas at Austin have developed a prototype jacket that harvests clean drinking water directly from the atmosphere, and it works even in the driest desert conditions.

The research, published in Science Advances, marks the latest milestone in nearly a decade of work by materials scientist and chair professor Guihua Yu and his team at the Cockrell School of Engineering's Walker Department of Mechanical Engineering and Texas Materials Institute. The wearable technology marks a significant leap: instead of a bulky, stationary machine, this jacket does the work.

"We have been working on atmospheric water harvesting technology for a number of years," Yu says. "This current version is even more wearable. We're transitioning from conventional, more stationary water harvesting to something truly portable and personal."

Yu's lab first published work on hydrogel-based water harvesting around 2019, and the jacket is the latest evolution of that platform, now called AirGel. Last year, the broader AirGel invention won the top prize in the graduate category of the National Collegiate Inventors Competition.

The jacket is woven with specially engineered hydrogel fibers; ultra-porous materials that attract and absorb moisture from the surrounding air much like a household desiccant. Unlike a desiccant, the material doesn't require intense heat to release that water. The hydrogel is thermally responsive, meaning a modest rise in temperature — even from mild solar heating — is enough to release the water it has captured.

So, somebody would be wearing the jacket, or perhaps carrying this gel-like textile as a blanket, as it passively absorbs moisture from the air. Then they would detach the textile panels and place them into a small, portable collector unit; essentially a compact heater. The water evaporates out of the textile, condenses inside the collector, and drips out as clean, drinkable water.

"It immediately becomes drinkable because it already goes through the distillation process," Yu explains.

In trials, the jacket produced between 400 and 900 milliliters of water per day depending on humidity, or roughly 14-30 ounces, nearly a quart, depending on the air's humidity. With one kilogram of the textile, the researchers found they could generate approximately 3.7-4 liters of water in arid conditions, and potentially double that in humid ones. So far, the team has tried the jacket out in very dry, semi-dry, and humid areas, and the jacket was able to pull water from each climate.

Lead researcher Chuxin Lei, a postdoctoral researcher on Yu's team and co-author on the paper, says the goal was to rethink who this technology could serve.

"Many current [atmospheric water harvesting] systems are still built as rigid or stationary platforms, making them less suitable for people who are moving, working outdoors, or operating in some remote environment. This lead us to ask whether we could build a water harvesting system that could become more like clothing — light, wearable, flexible, and naturally suited for personal use," Lei says.

The potential applications are wide-ranging. Yu's team has previously worked with the Department of Defense on water solutions for soldiers, where water logistics can be dangerous and costly. The technology could also serve hikers, emergency responders, disaster relief workers, and agricultural and field workers. Anyone who needs clean water on the go and far from infrastructure.

The team also sees a potential future where the technology complements large-scale centralized water systems rather than replacing them.

"Our solution cannot be a universal solution for all," Yu acknowledges. "But I think it's an extremely important alternative."

For now, the jacket is still a laboratory prototype, but Yu and Lei are optimistic. With the right industry partnerships, they say, the technology could realistically reach commercial scale within three to five years.
