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 ranks among the 15 best cities in America for 2025

Ranking It

A new national report ranking the best cities in America has declared Houston is the 13th best U.S. city in 2025.

The annual "America's Best Cities" report from Resonance Consultancy, a Canada-based real estate and tourism marketing firm, ranks the relative qualities of livability, cultural "lovability," and economic prosperity in America's principal cities with metropolitan populations of 500,000 or more.

These top 100 cities "brilliantly weave local culture with economic prospects, aligning with global and domestic travel trends to create premier experiences for both residents and travelers."

Houston's new placement is three spots lower than its triumphant No. 10 rank in 2024. Though it no longer holds a prized top-10 spot, the report hails Houston as a "coveted hometown for the best and brightest on earth."

Among Houston's other shining attributes are its booming population growth – which has now grown to a staggering 7.51 million people – plus its competitive real estate market and a vibrant hospitality and culinary scene. Additionally, Houston earned a well-deserved No. 4 rank in the report's "restaurants" subcategory.

"A 221-room Home2 Suites/Tru by Hilton debuted near Toyota Center in March, while Marriott’s newly renovated Residence Inn NASA/Clear Lake keeps surging visitors happy," the report said. "West Houston’s Greenside will convert 35,000 square feet of warehouses into a park-laced retail hub by 2026, while America’s inaugural Ismaili Center, rising along Allen Parkway, remains on schedule for later this year, adding yet another cultural jewel to H-Town’s festival-fueled mosaic."

The report additionally puts a large focus on Houston's innovative energy sector and its numerous large companies that boost the local economy and create thousands of jobs. Several of these Houston-based companies are some of the best places to work, according to U.S. News and World Report.

One such company that was specifically praised in the report was the HyVelocity Hub, which aims to "ensure economic resilience and long-lasting, domestic energy production" along the Gulf Coast.

"The HyVelocity Hydrogen Hub just locked in up to $1.2 billion from the U.S. DOE, targeting 45,000 jobs and slicing 7.7 million tons of CO₂ a year," the report said.

Elsewhere in Texas

Dallas (No. 14) and Austin (No. 15) ranked right behind Houston in the top 20, while San Antonio sank into the No. 41 spot after previously ranking 32nd last year. El Paso also fell from No. 83 in 2024 to No. 100 this year.

Jason McGrath, the executive vice president and head of U.S. Corporate Reputation at Ipsos, said in the report that American cities are proving their resiliency as they are faced with "climate issues, increasing infrastructural demands, and shifting geopolitical landscapes affecting international relations and travel."

"Despite these hurdles, cities are creatively reinventing themselves to shine as examples of cultural vibrancy and innovation, keeping their competitive edge both locally and globally," McGrath said. "Our report shows that the allure of American cities remains strong, thanks to their rich diversity and vast attractions — from natural wonders to buzzing cultural hubs."

The top 10 best cities in America in 2025 are:

  • No. 1 – New York City, New York
  • No. 2 – Los Angeles, California
  • No. 3 – Chicago, Illinois
  • No. 4 – San Francisco, California
  • No. 5 – Seattle, Washington
  • No. 6 – Miami, Florida
  • No. 7 – Boston, Massachusetts
  • No. 8 – Washington, D.C.
  • No. 9 – Las Vegas, Nevada
  • No. 10 – San Diego, California

Houston biosciences company opens new sequencing center for drug development

bioscience breakthroughs

Houston-based Avance Biosciences has launched the Next-Generation Sequencing Center of Excellence, designed to enhance the company’s sequencing capabilities for drug development. Specifically, the facility at the company’s main campus in Northwest Houston will pursue breakthroughs in biologics, cell therapy and gene therapy.

In the drug industry, sequencing refers to studying nucleotides in DNA and RNA molecules. Nucleotides are the building blocks of DNA and RNA.

“This is a major milestone for Avance Biosciences as we continue to support the evolving needs of biologics and cell and gene therapy developers,” Xuening “James” Huang, co-founder, CEO and chief technology officer of Avance, said in a news release. “By consolidating state-of-the-art sequencing platforms and scientific talent, we’ve created a highly capable organization ready to solve complex genomic challenges with precision and compliance.”

In 2013, Avance rolled out next-generation sequencing (NGS) that complies with federal guidelines. Since then, Avance “has remained at the forefront of regulated sequencing services,” the company said. “The launch of the (new center) strengthens the company’s ability to deliver accurate, reproducible, and regulatory-aligned sequencing data across a wide array of therapeutic modalities.”

Cal Froberg, senior vice president of sales and marketing at Avance, said pharmaceutical and biotech clients trust the company’s technical capabilities and regulatory compliance.

“With the ever-changing global landscape and increasing scrutiny around international sample shipments, conducting advanced, cost-effective NGS testing domestically is now more feasible than ever,” Froberg said. “Our clients have confidence that their samples will remain in the U.S.”

Avance, founded in 2010, plans to hold an open house at the new facility in September to showcase its capabilities, technology, talent, and services. The company’s services include sequencing, molecular biology, cell-based testing, and bioanalytical testing.
