SpaceX Catches Starship Upper Stage With Chopstick Arms in Major Reusability Milestone
Two mechanical arms closed around it as it hovered beside the tower
Mark
So what actually happened on Saturday?
Mimi
The Starship upper stage came back to the Texas launch tower it left a day earlier, after 14 orbits and more than 22 hours. Two mechanical arms caught it as it hovered.
Mark
And the booster?
Mimi
It failed to return to the pad about 10 minutes after liftoff. So the plan to recover both parts for the first time didn't happen.
Luke
Worth being clear that this is one stage caught, not a fully reusable system. Nothing here says the vehicle is ready to refly.
Mark
Why does the upper stage matter more than the booster?
Mimi
Falcon 9's second stage is thrown away into the ocean every flight. Starship's upper stage is the part that carries payloads, so catching it is the harder step toward airline-style flying.
Mark
What about the heatshield?
Mimi
The tiles aren't fully reusable yet. SpaceX is designing new ones meant to need little or no refurbishment.
Luke
And we don't know the condition of the tiles after this flight. The reporting doesn't say, so I wouldn't assume they came through well.
Mark
How does it compare to the Space Shuttle?
Mimi
The Shuttle discarded its boosters and its orbiter needed extensive refurbishment. Starship aims to do better on both counts.
Luke
Aims is the operative word. Musk's goals, including the moon and Mars, are ambitions, not results from this flight.
Il Polso
- The upper stage came home after more than 22 hours in orbit, slowing through punishing re-entry heat until it hovered beside the tower.
- The Super Heavy booster failed about ten minutes after liftoff, shattering the plan to recover both stages together.
- Mechanical arms nicknamed chopsticks closed around the returning vessel, a first key recovery in SpaceX's long push toward full reuse.
- The heatshield's black tiles still need heavy refurbishment between flights, and engineers are racing to design replacements that need almost nothing.
On a Saturday over the south Texas coast, a rocket that had spent more than a day circling the Earth returned to the tower that had launched it, its mechanical arms closing around it in a moment that reads as a quiet turn in an old human ambition: to make the vehicles that carry us above the sky behave like the vehicles that carry us across the ocean. SpaceX's Starship upper stage completed fourteen orbits and was caught, a first for this vessel, though the booster that was meant to return alongside it fell short, so the larger dream of recovering a whole rocket in a single flight remains unfinished. The distance between a single caught stage and a truly reusable spaceflight system is where the story now lives.
On Saturday, above the Gulf coast of south Texas, SpaceX's Starship spacecraft slowed from orbital speed, turned upright, and hovered beside the launch tower it had left the day before. Two mechanical arms, which the company calls chopsticks, closed around it. It was the first key recovery of the vessel at the heart of SpaceX's effort to build a fully reusable rocket.
The flight had begun on Friday from Starbase, Texas, with the Super Heavy booster carrying Starship skyward. SpaceX had hoped to recover both halves for the first time, but the booster failed to return about ten minutes after liftoff, and that ended the plan to catch both stages in one mission.
The upper stage carried on alone. It circled Earth fourteen times over more than 22 hours, its longest orbital flight yet, and deployed 26 Starlink satellites before beginning its descent. Its heatshield, made of black hexagonal tiles, endured the intense heat of re-entry before the engines fired to flip it vertical and guide it into the waiting arms.
The milestone matters because SpaceX's dominance rests on the Falcon 9, whose second stage is still discarded after every flight. Elon Musk sees Starship as the workhorse that could one day make spaceflight as routine as air travel. Yet the catch does not complete that vision, since both stages have not yet been recovered together and the heatshield is not yet fully reusable. The company is now working on tile designs that would need little or no refurbishment between flights.
On Saturday local time, above the Gulf coast of south Texas, SpaceX's Starship spacecraft slowed from orbital speed, flipped upright, and hovered beside the launch tower it had left a day earlier. Two mechanical arms, which the company calls chopsticks, closed around it. It was the first key recovery of the centrepiece vessel in SpaceX's decade-long effort to build a fully reusable rocket.
The flight began on Friday from Starbase, Texas. The Super Heavy booster, the bottom half of the two-stage rocket, carried Starship to space. SpaceX had planned to recover both halves for the first time, but the booster failed to make its own return to the launch pad about 10 minutes after liftoff. That ended the plan to catch both stages in one mission.
The upper stage then did what the booster could not. It orbited Earth 14 times over more than 22 hours, its longest orbital flight yet. On Friday night, at an altitude of about 161 miles (260km), it deployed 26 Starlink satellites.
The return began on Saturday, when Starship fired one of its engines to start its descent. It met blistering heat as its speed of roughly 17,000 miles per hour (about 27,350km per hour) fell away to a supersonic free-fall above the Starbase facilities. Near the end it reignited three engines to flip into a vertical position and steer toward the tower, where the arms caught it as it hovered.
The milestone matters because of how SpaceX makes its money today. Its dominance of the global launch industry rests on the Falcon 9, which has flown more than 700 times since 2010. The Falcon 9's first stage is reusable, but its second stage, the part that delivers payloads into orbit, is discarded into the ocean after every flight. Elon Musk wants Starship to fly to space and back in a manner and tempo akin to commercial airplanes. He sees it as the future workhorse of SpaceX's satellite business and of its ambitions to put humans on the moon and eventually Mars.
Saturday's catch does not complete that vision. SpaceX has yet to recover both Starship stages in a single mission. The heatshield, made of black hexagonal tiles that protect the vessel during re-entry, is also not yet fully reusable. The company is working on new tile designs that would need little to no refurbishment after each flight.
There is a historical yardstick. NASA's Space Shuttle, which ferried astronauts to the International Space Station until its retirement in 2011, was only partially reusable. Its booster stages were discarded after each flight, and the reusable orbiter needed extensive refurbishment before it could fly again.
What to watch next is whether SpaceX can bring both stages back together on one mission, and whether its new heatshield tiles can cut the refurbishment between flights to almost nothing.
