With more than 20 years of operations in low Earth orbit, we are preparing our return to the Moon for long-term exploration and discovery before taking the next giant leap to Mars.
Never has humanity endeavored to simultaneously architect multinational infrastructures in lunar orbit, on the lunar surface, and at Mars — all while maintaining high-demand government and private-sector operations in low Earth orbit.
On flight day 13, Orion reached its maximum distance from Earth during the Artemis I mission when it was 268,563 miles away from our home planet. Orion has now traveled farther than any other spacecraft built for humans.
Space Station Expedition 70
The Expedition 70 crew began on Sept. 27, 2023. The astronauts and cosmonauts will be studying an array of microgravity phenomena to benefit humans living on and off the Earth. The orbital residents will also explore heart health, cancer treatments, space manufacturing techniques, and more during their long-duration stay in Earth orbit.
This illustration shows NASA’s Cassini spacecraft in orbit around Saturn. Cassini made 22 orbits that swooped between the rings and the planet before ending its mission on Sept. 15, 2017, with a final plunge into Saturn.
Artemis Missions to the Moon
The Artemis era is here. The Artemis I uncrewed flight test flew in 2022, and we are gearing up for the next flight test, this time with four astronauts.
