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.

Houston scores $120M in new cancer research and prevention grants

cancer funding

The Cancer Prevention and Research Institute of Texas has granted more than $120 million to Houston organizations and companies as part of 73 new awards issued statewide.

The funds are part of nearly $154 million approved by the CPRIT's governing board earlier this month, bringing the organization's total investment in cancer prevention and research to more than $4 billion since its inception.

“Today marks an important milestone for CPRIT and for every Texan affected by cancer,” CEO Kristen Doyle said in a news release. “Texas has invested $4 billion in the fight against one of the world’s greatest public health challenges. Over 16 years, that support has helped Texas lead the search for breakthrough treatments, develop new cancer-fighting drugs and devices, and—most importantly—save tens of thousands of lives through early cancer detection and prevention. Every Texan should know this effort matters, and we’re not finished yet. Together, we will conquer cancer.”

A portion of the funding will go toward recruiting leading cancer researchers to Houston. CPRIT granted $5 million to bring John Quackenbush to Baylor College of Medicine. Quackenbush comes from the Harvard T.H. Chan School of Public Health and is an expert in computational and systems biology. His research focuses on complex genomic data to understand cancer and develop targeted therapies.

The University of Texas M.D. Anderson Cancer Center also received $3 million to recruit Irfan Asangani, an associate professor at the University of Pennsylvania Perelman School of Medicine. His research focuses on how chromatin structure and epigenetic regulation drive the development and progression of cancer, especially prostate cancer.

Other funds will go towards research on a rare, aggressive kidney cancer that impacts children and young adults; screening programs for breast and cervical cancer; and diagnostic technology.

In total, cancer grants were given to:

  • The University of Texas M.D. Anderson Cancer Center: $29.02 million
  • Baylor College of Medicine: $15.04 million
  • The University of Texas Health Science Center at Houston: $9.37 million
  • Texas A&M University System Health Science Center: $1.2 million
  • University of Houston: $900,000

Additional Houston-based companies landed grants, including:

  • Crossbridge Bio Inc.: $15.01 million
  • OncoMAGNETx Inc.: $13.97 million
  • Immunogenesis Inc.: $10.85 million
  • Diakonos Oncology Corporation: $7.16 million
  • Iterion Therapeutics Inc.: $7.13 million
  • NovaScan Inc.: $3.7 million
  • EMPIRI Inc.: $2.59 million
  • Air Surgical Inc.: $2.58 million
  • Light and Salt Association: $2.45 million
