Orion and SLS

The crew capsule and heavy-lift rocket that carry Artemis astronauts to the Moon.

Orion is NASA's deep space crew capsule, built to keep four astronauts alive for weeks beyond low Earth orbit and to survive reentry at lunar-return speeds of 25,000 mph. The Space Launch System (SLS) is the rocket that throws it moonward: the most powerful rocket NASA has ever flown, producing 8.8 million pounds of thrust at liftoff.

The pair flew together for the first time on Artemis I in 2022, sending an uncrewed Orion 40,000 miles past the Moon and back. Orion's European-built service module supplies power and propulsion, making it NASA's most international crew vehicle.

No other spacecraft flying today is rated to carry humans beyond Earth orbit. Every Artemis crew rides Orion, and every Orion rides SLS. If this hardware slips, the Moon landing slips with it.
