NASA is holding a news conference to give an update on the space agency's Artemis II mission.
What is the mission?
In September 2025, the Artemis II mission will see four astronauts fly around the moon on the Orion spacecraft.
It is hoped that the 10-day flight will help NASA return astronauts to the moon and establish a long-term presence there for exploration.
It will be NASA's first mission with a crew aboard the Space Launch System rocket (SLS) and Orion spacecraft.
"The unique Artemis II mission profile will build upon the uncrewed Artemis I flight test by demonstrating a broad range of SLS and Orion capabilities needed on deep space missions," Mike Sarafin, Artemis mission manager, said.
"This mission will prove Orion's critical life support systems are ready to sustain our astronauts on longer duration missions ahead, and allow the crew to practice operations essential to the success of Artemis III."
What happened during Artemis I?
In 2022, Artemis I took off from Kennedy Space Center at Cape Canaveral.
The mission was made up of three stages.
The first was a 42-day uncrewed flight around the moon. It tested the huge rocket and the Orion spacecraft.
While in space it deployed 10 CubeSats (a type of miniaturised satellite), which performed a variety of work in deep space, from studying how radiation affects DNA to hunting for water ice on the moon.
It then splashed into the Pacific Ocean after nearly 26 days in space on 22 November 2022.
What are the hopes for Artemis III?
The Artemis III mission blasts off in 2026, and aims to help scientists learn more about how the moon formed and evolved, and whether humans could live there.
Orion and a crew of four will once again travel to the moon, this time to make history with the first woman and next man to walk on its surface.
