What time did NASA’s Artemis II mission launch?
The launch took place at 6:35 p.m. ET from the Kennedy Space Center in Florida, United States.
How many days will NASA astronauts spend in space?
The ArtemisII mission is planned to last approximately ten days from launch to return to Earth.
Who are the astronauts flying on NASA’s Artemis II mission?
The Artemis II crew is made up of four highly experienced astronauts who will orbit the Moon and test the Orion spacecraft’s systems under real conditions. They are:
- • Reid Wiseman: a NASA astronaut and the mission’s commander. He is a former naval aviator with experience aboard the International Space Station, where he took part in long-duration missions.
- • Victor Glover: the mission pilot. A naval aviator and astronaut, he previously flew on SpaceX’s Crew-1 mission, making him a key figure in flight operations.
- • Christina Koch: mission specialist. She is known for taking part in one of the longest spaceflights by a woman and for being part of the first all-female spacewalk.
- • Jeremy Hansen: mission specialist and astronaut with the Canadian Space Agency. He will become the first Canadian to travel to the Moon, marking a major international milestone within the Artemis program.

What is NASA’s Artemis II mission like?
ArtemisII is a crewed test flight within NASA’s Artemis program. The mission involves sending a crew of four astronauts aboard the Orion spacecraft, powered by the Space Launch System (SLS) rocket, on a lunar flyby trajectory without landing. The objectives include verifying the operation of Orion’s life support, communications, and navigation systems with humans on board in deep space, as well as collecting operational data to support future lunar landing missions starting with ArtemisIII.
When will Artemis II reach the Moon?
According to NASA’s official schedule, the ArtemisII mission is expected to begin its lunar flyby starting Monday, April 6.
Where to watch NASA’s Artemis II mission live?
Live coverage of the ArtemisII mission is available on NASA’s official channels:
- • NASA TV
- • NASA+ streaming platform
- • NASA’s official YouTube channel
- • NASA’s social media accounts (X, Facebook, Twitch)
What is the Orion spacecraft like for Artemis II?
Orion is the spacecraft designed by NASA to carry astronauts beyond low Earth orbit. It is a modern capsule equipped with advanced technology that enables long-duration missions in deep space.
It features life-support systems, high-precision navigation, and heat shielding capable of withstanding reentry into Earth’s atmosphere at high speeds. Orion is also designed to dock with other modules in future missions, making it a key component for sustained lunar exploration.
For Artemis II, the spacecraft will be tested with a crew on board for the first time, helping validate its performance ahead of future missions aimed at landing on the Moon.
What is NASA?
NASA is the United States government’s civilian agency responsible for aeronautics research and space exploration. Established in 1958, its mandate includes developing aerospace technologies, conducting scientific research on Earth and in space, and carrying out crewed and uncrewed missions to expand human knowledge of the universe. The agency has led key projects such as the Apollo programs, the Space Shuttle, and various planetary exploration probes, establishing itself as a central player in the international scientific community.
