In engineering feat, mechanical SpaceX arms catch Starship rocket booster back at launch pad
Washington, Oct 13: SpaceX pulled off the boldest test flight yet of its enormous Starship rocket on Sunday, catching the returning booster back at the launch pad with mechanical arms.
A jubilant Elon Musk called it “science fiction without the fiction part”.
Towering almost 400 feet (121 metres), the empty Starship blasted off at sunrise from the southern tip of Texas near the Mexican border. It arced over the Gulf of Mexico like the four Starships before it that ended up being destroyed, either soon after liftoff or while ditching into the sea. The previous one in June had been the most successful until Sunday's demo, completing its flight without exploding.
This time, Musk, SpaceX's CEO and founder, upped the challenge for the rocket that he plans to use to send people back to the moon and on to Mars.
At the flight director's command, the first-stage booster flew back to the launch pad where it had blasted off seven minutes earlier. The launch tower's monstrous metal arms, dubbed chopsticks, caught the descending 232-foot (71-metre) booster and gripped it tightly, dangling it well above the ground.
“The tower has caught the rocket!!” Musk announced via X. “Big step towards making life multiplanetary was made today.”
Company employees screamed in joy, jumping and pumping their fists into the air as the stainless steel booster slowly lowered itself into the launch tower's arms. NASA joined in the celebration, with Administrator Bill Nelson sending congratulations.
“Even in this day and age, what we just saw is magic,” SpaceX spokesman Dan Huot observed from near the launch site. “I am shaking right now.”
“Folks, this is a day for the engineering history books,” added engineering manager Kate Tice from SpaceX headquarters in Hawthorne, California.
An hour later, the empty spacecraft that was launched atop the booster made a controlled landing in the Indian Ocean as planned, adding to the day's achievement.
It was up to the flight director to decide, in real time with a manual control, whether to attempt the landing. SpaceX said both the booster and launch tower had to be in good, stable condition. Otherwise, it was going to end up in the gulf like the previous ones. Everything was judged to be ready for the catch.
The retro-looking stainless steel spacecraft on top continued around the world once it was free of the booster. Cameras on a buoy in the Indian Ocean showed flames shooting up from the water as the booster impacted precisely at the targeted spot and sank, as planned.
“What a day,” Huot said. “Let's get ready for the next one.”
The June flight came up short at the end after pieces came off. SpaceX upgraded the software and reworked the heat shield, improving the thermal tiles.
SpaceX has been recovering the first-stage boosters of its smaller Falcon 9 rockets for nine years, after delivering satellites and crews to orbit from Florida or California. But they land on floating ocean platforms or on concrete slabs several miles from their launch pads — not on them.
Recycling Falcon boosters has sped up the launch rate and saved SpaceX millions. Musk intends to do the same for Starship, the biggest and most powerful rocket ever built with 33 methane-fuel engines on the booster alone. NASA has ordered two Starships to land astronauts on the moon later this decade. SpaceX intends to use Starship to send people and supplies to the moon and, eventually Mars.

Healthy eating in 40s linked to better well-being in 70s: Harvard study
Washington: A recent Harvard study has found that dietary choices made in the 40s can have a significant impact on health and quality of life in the 70s. The research, published in Nature Medicine, emphasises the role of a balanced and nutritious diet in preventing chronic diseases and promoting overall well-being in later years.
The study defines healthy ageing as reaching 70 without major chronic illnesses such as cancer, heart disease, diabetes, or cognitive decline while maintaining physical independence and a good quality of life.
Researchers monitored the eating habits of 105,015 individuals over three decades, evaluating their diets based on eight recognised healthy eating guidelines. The Alternative Healthy Eating Index (AHEI), developed by Harvard, was identified as the most effective diet for promoting healthy ageing. This diet emphasises the consumption of fruits, vegetables, whole grains, nuts, legumes, and healthy fats found in olive oil and fatty fish while discouraging red and processed meats, sugary beverages, refined grains, and high sodium intake.
Experts suggest that while no single diet suits everyone, incorporating nutrient-rich foods, opting for whole grains, and prioritising healthy fats over trans and saturated fats can contribute to better health as individuals age.
