SpaceX successfully launched its Starship megarocket Thursday on an uncrewed test flight to orbit and back, achieving several key milestones for the first time.
The nearly 400-foot rocket is the most powerful booster ever developed and SpaceX aims to make the system fully reusable.
It is being designed to carry out missions to the moon and eventually Mars. Starship is expected to play an important part inNASA’s return-to-the-moon program: The agency selected it to carry astronauts to the lunar surface on its Artemis III mission, which could launch in 2026.
Starship lifted off at 8:50 a.m. ET from SpaceX’s Starbase launch site in Boca Chica, Texas.This was the spacecraft's fourth test flight and the first time it survived the full journey from liftoff to splashdown. However, it's not yet clear how much of the vehicle survived re-entry through Earth’s atmosphere.
Still, the test flight notched several crucial milestones. SpaceX showed that both the Starship spacecraft and the rocket’s first-stage, known as Super Heavy, can survive the fiery trip back through Earth’s atmosphere and make a “soft” and controlled splash down.
Less than 10 minutes after liftoff, Super Heavy executed a successful landing burn for the first time and splashed down in the Gulf of Mexico. After cruising in orbit for around 40 minutes, the Starship spacecraft made its re-entry and completed a landing burn for the first time.
Live camera views aboard Starship showed debris and damage to the vehicle before it splashed down in the Indian Ocean, but SpaceX heralded the test flight as a success.
“Congratulations @SpaceX team on an epic achievement,” Elon Musk, the company’s founder and CEO, said on X.
Starship's flight came during a busy week of launches: On Wednesday, Boeing's Starliner capsule launched on its first crewed test flight to the International Space Station.
Relive the launch in slo-mo

SpaceX released a video of Starship's launch in slow-motion, showing the rocket thunder to life and lift off the pad.
'An epic achievement,' Elon Musk says
Denise Chow
Elon Musk, SpaceX's founder and CEO, called today's test flight an "epic achievement."
"Despite loss of many tiles and a damaged flap, Starship made it all the way to a soft landing in the ocean!" he posted on X.
'Toasting' Starship
Denise Chow
SpaceX employees toasted marshmallows to celebrate Starship's "toasty" ride through the atmosphere.
It will likely take some time for the company to release data and results from today's outing, but SpaceX continues to make progress with each ambitious Starship test flight.
Starship's first-ever landing burn
Denise Chow
Starship appears to have successfully executed its first-ever landing burn before splashing down in the ocean. It's not yet clear how much of the ship survived re-entry through the atmosphere, but mission controllers confirmed that the vehicle completed the key burn.
Still celebrating
Denise Chow
Video feeds from Starship have been spotty during re-entry, as is to be expected but you can hear cheers from SpaceX employees at the company's headquarters in Hawthorne, California, every time live views return.
"This is a nail-biter," one launch commentator said.
Next up: splashdown
Denise Chow
Splashdown is expected in a few minutes, but it's unclear how much of Starship has survived at this point.
Burning up?
Denise Chow
Pieces of Starship appear to be burning off as the spacecraft makes its way through the atmosphere.
Debris seems to be covering the onboard cameras, at least one of which now has a cracked lens, but the company still seems to be able to collect data from Starship.
Live views of re-entry
Denise Chow
Cameras are capturing incredible live views of Starship's re-entry, showing plasma building around the spacecraft as it travels through the atmosphere.
It's rare to get a real-time look at this intense and high-stakes phase of a space vehicle's return to Earth.
From re-entry to landing
Denise Chow
The entire re-entry process is expected to last for about 6 minutes.
If Starship survives the fiery trip through the planet's atmosphere, it should then fire its engines to flip over, then execute a key landing burn before splashing down in the Indian Ocean.
Starship begins re-entry
Denise Chow
Starship is now attempting to execute the primary objective of today's test flight: re-entering Earth's atmosphere and splashing down in the Indian Ocean.
There is typically a communications blackout during this time, so it may take some time to confirm if the vehicle has survived the re-entry process.
A busy week of space launches
Denise Chow
This morning's liftoff followed yesterday's launch of Boeing's Starliner capsule to the International Space Station. It's the spacecraft's first crewed flight — veteran NASA astronauts Butch Wilmore and Suni Williams are currently onboard in low-Earth orbit.
The Starliner spacecraft is expected to dock with the space station today at 12:15 p.m. ET. You can catch up on the news of yesterday's launch here.
What's next for Starship
Denise Chow
Starship has been flying for more than 20 minutes. Roughly 47 minutes into the flight, the vehicle will attempt to re-enter the atmosphere and land "softly" in the Indian Ocean.
It will be high-stakes moment for SpaceX. During Starship's last test flight in March, the company said it lost contact with the spacecraft roughly 50 minutes into the flight, at an altitude of around 40 miles.
Today, SpaceX is hoping to show that Starship can survive the extreme temperatures of atmospheric re-entry and execute a controlled splashdown.
Short break before landing
Denise Chow
The live webcast is pausing for about 30 minutes as Starship continues to coast in orbit.
The next milestone will come when Starship attempts to re-enter Earth's atmosphere and splash down in the Indian Ocean.
Celebrations from Texas
Denise Chow
You can hear big cheers erupt from SpaceX employees at each milestone of the flight. The team has already accomplished one of the main objectives of today's test.
Splashdown of Super Heavy
Denise Chow
SpaceX confirmed that the Super Heavy booster executed a successful landing burn and splashdown in the Gulf of Mexico. This is a big milestone for the company.
Starship is now coasting
Denise Chow
Starship is now expected to coast for about 40 minutes up to an altitude of roughly 130 miles.
Meanwhile, the Super Heavy booster is attempting to make a controlled and "soft" landing in the Gulf of Mexico. During Starship's last test flight in March, Super Heavy did not execute a planned landing burn and was lost at around this stage of the flight.
And there it goes

Starship separation confirmed
Denise Chow
The Starship spacecraft has successfully separated from the Super Heavy first-stage booster, SpaceX confirmed.
The rocket's ascent seemed smooth, though it looked like one of the rocket's Raptor engines did not light at liftoff.
The moment of liftoff
Jason Abbruzzese
SpaceX quickly posted a video of Starship's liftoff:
Looking good so far
Denise Chow
The rocket passed through what's known as "Max Q," the moment of maximum dynamic pressure on Starship's ascent. The vehicle is now supersonic, flying faster than the speed of sound.
We have liftoff
Denise Chow
The rocket has cleared the launch tower.
Fueling complete
Denise Chow
SpaceX officials said the rocket and spacecraft are now fully loaded with 10 million pounds of propellant.
Five minutes to go
Denise Chow
SpaceX said it is not working any issues ahead of the targeted launch at 8:50 a.m. ET.
If any issues do crop up, the company has a built-in hold in their launch countdown at T-minus 40 seconds. That means they can hold there for up to 30 minutes, if needed.
Weather looks good for launch
Denise Chow
It looks cloudy around the launch pad, but SpaceX says weather conditions remain 95% favorable for this morning's launch.
Starship's flight trajectory
NBC News
Take a look at what's in store for Starship as it prepares to journey into orbit and back.
Main objectives for today's flight
Denise Chow
SpaceX is aiming to show that both the Super Heavy first-stage booster and Starship spacecraft can survive re-entry through Earth's atmosphere and achieve a "soft" splashdown.
Super Heavy is targeting a splashdown in the Gulf of Mexico. After reaching orbit, the Starship vehicle will aim to splash down in the Indian Ocean.
Both objectives will be crucial in developing Starship into a fully reusable system, which SpaceX has said will drive down costs and allow for quicker turnarounds between launches.
While full reusability is the company's ultimate goal, SpaceX said it is not planning to recover any hardware from today's test flight.
Live webcast underway

SpaceX's webcast of today's launch has begun. You can follow along on X.
How Starship stacks up
Denise Chow
The nearly 400-foot-tall Starship megarocket is the most powerful booster ever developed. It is designed to take astronauts to the moon — and one day, perhaps on to Mars.
NASA is separately developing its ownSpace Launch System megarocket and Orion spacecraftfor missions to the moon. As part of the agency’s Artemis program, NASA envisions regular missions to establish a base camp on the lunar surface before an eventual mission to Mars.
But the two rockets have key differences. Unlike NASA’s Space Launch System, SpaceX's Starship rocket will be fully reusable. A key objective of today’s test flight will be to demonstrate that the booster’s first stage, dubbed Super Heavy, can safely return to Earth and splash down in the Gulf of Mexico.
Astronaut Chris Hadfield hopes for "soft landings"
Jason Abbruzzese
Chris Hadfield posted his best wishes for a successful launch — and landing — for Starship.
Fueling underway
Denise Chow
SpaceX officials confirmed that fueling is currently underway. Starship uses liquid methane and liquid oxygen propellant.
What to expect for this flight
Denise Chow
SpaceX made steady progress with each of its three prior Starship tests. Therocket’s debut flight in April 2023ended when the booster exploded several minutes after liftoff.
Asecond Starship launchin November achieved several milestones, including the separation of the first-stage booster and upper-stage spacecraft, but thecompany lost contact with the vehicleshortly after.
Starship’s third test flight in March saw the spacecraft successfully reach orbit, but the vehicle was lost as it re-entered Earth’s atmosphere.
On Starship’s fourth test flight, SpaceX aims to show that both the upper-stage spacecraft and the rocket’s first-stage booster, known as Super Heavy, can make controlled, safe landings on Earth.
During the last test flight, a planned burn in the landing process failed and the Super Heavy booster ultimately broke apart over the Gulf of Mexico. This time, SpaceX hopes to execute the landing burn successfully, achieving a “soft splashdown” of the booster in the Gulf of Mexico. It is also looking to nail a “controlled entry” of the Starship vehicle through Earth’s atmosphere before it splashes down in the Indian Ocean.
Throwback to March
NBC News
This morning's test flight will follow a similar trajectory as Starship's last outing in March. Here's a look back at some of the highlights from that launch.
Live from Texas
