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.

Houston geothermal unicorn Fervo officially files for IPO

going public

Fervo Energy has officially filed for IPO.

The Houston-based geothermal unicorn filed a registration statement on Form S-1 with the U.S. Securities and Exchange Commission on April 17 to list its Class A common stock on the Nasdaq exchange. Fervo intends to be listed under the ticker symbol "FRVO."

The number and price of the shares have not yet been determined, according to a news release from Fervo. J.P. Morgan, BofA Securities, RBC Capital Markets and Barclays are leading the offering.

The highly anticipated filing comes as Fervo readies its flagship Cape Station geothermal project to deliver its first power later this year

"Today, miles-long lines for gasoline have been replaced by lines for electricity. Tech companies compete for megawatts to claim AI market share. Manufacturers jockey for power to strengthen American industry. Utilities demand clean, firm electricity to stabilize the grid," Fervo CEO Tim Latimer shared in the filing. "Fervo is prepared to serve all of these customers. Not with complex, idiosyncratic projects but with a simplified, standardized product capable of delivering around-the-clock, carbon-free power using proven oil and gas technology."

Fervo has been preparing to file for IPO for months. Axios Pro first reported that the company "quietly" filed for an IPO in January and estimated it would be valued between $2 billion and $3 billion.

Fervo also closed $421 million in non-recourse debt financing for the first phase of Cape Station last month and raised a $462 million Series E in December. The company also announced the addition of four heavyweights to its board of directors last week, including Meg Whitman, former CEO of eBay, Hewlett-Packard, and Spring-based HPE.

Fervo reported a net loss of $70.5 million for the 2025 fiscal year in the S-1 filing and a loss of $41.1 million in 2024.

Tracxn.com estimates that Fervo has raised $1.12 billion over 12 funding rounds. The company was founded in 2017 by Latimer and CTO Jack Norbeck.

New UT Austin med center, anchored by MD Anderson, gets $1 billion gift

Future of Health

A donation announced Tuesday, April 21, breaks a major record at the University of Texas at Austin. Michael and Susan Dell are now UT Austin's first supporters to give $1 billion. In response, the university will create the UT Dell Campus for Advanced Research and the UT Dell Medical Center to "advance human health," per a press release.

The release also records "significant support" for undergraduate scholarships, student housing, and the Texas Advanced Computing Center for supercomputing research.

Both the new research campus and the UT Dell Medical Center will integrate advanced computing into their research and practices. At the medical center, the university hopes that will lead to "earlier detection, more precise and personalized care, and better health outcomes." The University of Texas MD Anderson Cancer Center will also be integrated into the new medical center.

That comes with a numeric goal measured in 10s: raise $10 billion and rank among the top 10 medical centers in the U.S., both in the next decade.

In the shorter term, the university will break ground on the medical center with architecture firm Skidmore, Owings & Merrill (SOM) "later this year."

“UT Austin, where Dell Technologies was founded from a dorm room, has always been a place where bold ideas become real-world impact,” said Michael and Susan Dell in a joint statement.

They continued, “What makes this moment so meaningful is the opportunity to build something that brings every part of the journey together — from how students learn, to how discoveries are made, to how care reaches families. By bringing together medicine, science and computing in one campus designed for the AI era, UT can create more opportunity, deliver better outcomes, and build a stronger future for communities across Texas and beyond.”

This is the second major gift this year for the planned multibillion-dollar medical center. In January, Tench Coxe, a former venture capitalist who’s a major shareholder in chipmaking giant Nvidia, and Simone Coxe, co-founder and former CEO of the Blanc & Otus PR firm, contributed $100 million$100 million.

Baylor scientist lands $2M grant to explore links between viruses and Alzheimer’s

Alzheimer’s research

A Baylor College of Medicine scientist will begin exploring the possible link between Alzheimer’s disease and viral infections thanks to a $2 million grant awarded in March.

Dr. Ryan S. Dhindsa is an assistant professor of pathology & immunology at Baylor and a principal investigator at Texas Children’s Duncan Neurological Research Institute (Duncan NRI). He hypothesizes that Alzheimer’s may have some link to previous viral infections contracted by the patient. To study this intriguing possibility, the American Brain Foundation has gifted him the Cure One, Cure Many award in neuroinflammation.

“It is an honor to receive this support from the Cure One, Cure Many Award. Viral infections are emerging as a major, underappreciated driver of Alzheimer's disease, and this award will allow our team to conduct the most comprehensive screen of viral exposures and host genetics in Alzheimer's to date, spanning over a million individuals,” Dhindsa said in a news release. “Our goal is to identify which viruses matter most, why some people are more vulnerable than others, and ultimately move the field closer to new therapeutic strategies for patients.”

Roughly 150 million people worldwide will suffer from Alzheimer’s by 2050, making it the most common cause of dementia in the world. Despite this, scientists are still at a loss as to what exactly causes it.

Dhindsa’s research is part of a new range of theories that certain viral infections may trigger Alzheimer’s. His team will take a two-fold approach. First, they will analyze the medical records of more than a million individuals looking for patterns. Second, they will analyze viral DNA in stem cell-derived brain cells to see how the infections could contribute to neurological decay. The scale of the genomic data gathering is unprecedented and may highlight a link that traditional studies have missed.

Also joining the project are Dr. Caleb Lareau of Memorial Sloan Kettering Cancer Center and Dr. Artem Babaian of the University of Toronto. Should a link be found, it would open the door to using anti-virals to prevent or treat Alzheimer’s.
