SpaceX’s Starship Achieves First Midair Upper-Stage Capture

On a cloudy Saturday afternoon in Texas, a pair of large metallic arms reached out and caught a giant spacecraft as it descended from the sky.

At 124 metres (407ft) tall, SpaceX’s Starship is the world’s largest and most powerful rocket, designed for travel to the Moon and Mars. Twenty-two hours after its latest launch, it made history on Earth during its return, sliding smoothly between the mechanical “chopstick arms” above Launch Pad 2 at Starbase in Texas.

Aerospace engineers around the world praised the first-ever capture of a spaceship’s upper stage and welcomed an achievement that signals mega rockets could soon become fully reusable.

Here is why the historic capture matters:

How did it work?

On Saturday, after orbiting Earth 14 times over 22.5 hours, SpaceX’s Starship emerged from thick clouds over its Starbase launch site, flipped itself into a vertical position and slowly descended into the arms on the “Mechazilla” launch tower.

Like massive tweezers, the arms caught the upper stage in midair while its engines were still roaring.

The spacecraft then hooked onto the tower’s mechanical arms and shut off its engines.

The roaring sound was instantly replaced by loud cheers from nearby watchers, who had just witnessed the first capture of a mega rocket in history.

“That was the missing link, the holy grail of spaceflight,” said SpaceX mission commentator Dan Huot. “We caught a Starship and now everything changes.”

“Congratulations to an incredible team at SpaceX!!!” SpaceX founder and CEO Elon Musk said.

NASA, which is paying billions of dollars for Starship to land astronauts on the Moon later this decade, also welcomed the achievement.

“It was almost magic,” NASA Administrator Jared Isaacman said on X.

“Making more believers by the day…one step closer to [the moon],” he added.

Why was the capture tricky?

Spacecraft returning to Earth must contend with gravity and a range of atmospheric factors that are nearly impossible to predict or control perfectly.

Sputnik 1, the first artificial satellite sent into space, burned up while returning to Earth.

Several crewed spacecraft have been destroyed during atmospheric re-entry, killing the astronauts on board.

In April 1967, the Soviet Union’s Soyuz 1 spacecraft re-entered the atmosphere successfully, but its parachutes failed to deploy properly. Cosmonaut Vladimir Komarov died in the crash-landing near the Ural Mountains. Decades later, NASA’s space shuttle Columbia disintegrated during re-entry from orbit, killing all seven astronauts on board.

In recent decades, space agencies and private firms have made major advances in safety. But many spacecraft cannot be reused after splashing down in the sea or landing on the ground.

Since October 2024, SpaceX has successfully caught boosters that propel the shuttle three times, after they ran out of fuel and separated from the main rocket.

But until now, the main spacecraft had never been successfully caught in midair.

Soon after its return, Musk and his engineers inspected the spaceship and said everything appeared to have worked well, including its vital heat shield.

“Ship 42 looks great!” Musk wrote on X, posting photos and videos from the launch tower.

While the capture was tricky, aerospace engineers said the upper-stage catch is a major success for SpaceX.

Niharika Patel, technical programme manager at Loft Orbital, a US-based space infrastructure company, told Al Jazeera that watching the catch happen was “magical.”

“Landing a rocket back on Earth is incredibly difficult and can itself be considered an engineering marvel. Now add the sheer size and weight of Starship to that equation,” she said, noting that this was also the first time the upper stage had been successfully caught.

“It requires incredible precision to ensure the vehicle reaches exactly the right position, withstands the extreme heat of atmospheric re-entry and executes highly controlled manoeuvres within a very tight window. And all of this happens without a pilot — it’s completely autonomous,” she added.

Why does it matter for space technology advances?

SpaceX has become dominant in the aerospace industry primarily because the company has sought to slash the cost of space travel through reusable rocket technology and rapid, repeat engineering.

So far, its Falcon 9 rocket has launched 700 times since 2010, with its first stage reusable and its second stage discarded into the sea.

With Starship, Musk has said he wants to create fully reusable flights that can also transport humans into space with minimal refurbishment.

“SpaceX has already significantly reduced the cost of getting to orbit through Falcon 9’s reusability. It’s super cheap and convenient to send satellites to low Earth orbit. Starship takes this a step further by being a much bigger craft and aiming for full reusability of both the booster and the upper stage,” Patel said.

She explained that a fully reusable vehicle can be rapidly refurbished and flown again, dramatically increasing frequency and reducing cost. If Starship reaches this milestone, Patel said, it would make access to space even more affordable and scalable, just as commercial aviation transformed travel by making aircraft reusable with quick turnaround times between flights.

“This is essential for the next era of space exploration, from deploying large satellite constellations and building space infrastructure to enabling sustained human exploration of the Moon and Mars,” Patel added.
