SpaceX's Starship rocket, designed to eventually send astronauts to the moon and beyond, completed nearly an entire test flight to space on its third try on Thursday but was destroyed during its return to Earth after making it farther than ever before.
During a live webcast of the flight, SpaceX commentators said mission control lost communications with the spacecraft during its atmospheric re-entry at hypersonic speed. The vehicle was nearing a planned splashdown in the Indian Ocean about an hour after launch from south Texas.
A few minutes later, SpaceX confirmed that the spacecraft had been "lost," presumably either burning up or coming apart during re-entry or crashing into the sea, Reuters reported.
For reasons that were left unclear, SpaceX opted to skip one of the test flight's core objectives - an attempt to re-ignite one of Starship's Raptor engines while it coasted in a shallow orbit. That milestone is considered key to its future success.
Still, completion of many of Starship's intended flight objectives represented a milestone in the development of a spacecraft crucial to the growing satellite launch business of SpaceX, founded by Elon Musk in 2002, and NASA's moon program.
NASA chief Bill Nelson congratulated SpaceX on what he called "a successful test flight" in a statement posted on social media platform X. SpaceX President Gwynne Shotwell wrote in an X post the test marked an "incredible day."
The two-stage spacecraft, consisting of the Starship cruise vessel mounted atop its towering Super Heavy rocket booster, blasted off from the company's Starbase launch site near Boca Chica Village on the Gulf Coast of Texas. The upper-stage Starship reached peak altitudes of 145 miles (234 km).
The spacecraft far exceeded its two past performances, both of which were cut short by explosions minutes after launch. The company had acknowledged in advance a high probability that its latest flight might similarly end with the spacecraft's demise before the mission profile was finished.
SpaceX's engineering culture, considered more risk-tolerant than many of the aerospace industry's more established players, is built on a flight-testing strategy that pushes spacecraft to the point of failure, then fine-tunes improvements through frequent repetition.



Chinese Study Recommends Region-Specific Diets, amid Rising Obesity Risks

Chinese scientists have recommended a region-specific diet they say is crucial to improving eating habits in the country amid a rise in obesity and lifestyle diseases, and as a means to conserve natural and environmental resources.

China in October published its first set of guidelines to standardize the diagnosis and treatment of obesity, with more than half of China's adults already overweight and obese, and the rate expected to keep rising. The government has said that healthier diets are important to treat and prevent obesity.

A group of scientists from the School of Public Health at Sun Yat-sen University in Guangzhou, in China's affluent southern Guangdong province, said its study adheres to a "Planetary Health Diet" and advocates a reduced consumption of dairy products and red meat.

Published in the Nature Food journal in August and reported in state media last week, the study recommended that in China's north, which is characterized by a high intake of dairy products but low consumption of vegetables, people need to eat more fruits and whole grains.

In the southwest, which has a harsher environment and severe water scarcity, the region could focus on a high intake of legumes and vegetables rather than its existing very high consumption of red meat, the study said.

In the east, known for its "affluent agricultural culture and developed aquaculture", a higher intake of whole grains, seafood and vegetables was recommended for its residents.

China's health commission did not immediately respond to an emailed request for comment.

The recommended diets work for the prevention of "obesity and cardio-metabolic diseases," said Liu Yan, one of the authors of the study, adding that they help reduce premature mortality and disability, and ensure nutritional requirements for residents.

Not only China but also other developing nations facing similar health and environmental challenges could benefit from the roadmap for the diet, the scientists said in the study.

Brent Loken, global food lead scientist for the World Wildlife Fund, said the study provided a promising way forward for developing countries, including India and Kenya.

"Adopting these planetary health diet variants could serve as a viable strategy for dietary shifts in China to achieve both human health and environmental sustainability goals... with lessons translatable to other countries around the world," he said.
