Artemis II Completes TLI, Heading to Moon on First Crewed Loop in 51 Years
Key Takeaways
- Artemis II left Earth orbit after a flawless translunar injection burn toward the Moon.
- The mission carries four astronauts heading to the Moon on the Orion spacecraft.
- The launch marks a historic return, first crewed lunar mission in more than 50 years.
TLI Success
Artemis II became the first crewed lunar mission in 51 years when the Orion spacecraft completed a five-minute, 49-second TLI burn.
The burn went flawlessly, and the crew was accelerated out of Earth orbit toward the Moon.

The crew will spend about eight days in space, testing life support and manual handling.
The mission could take the crew farther from Earth than any humans have traveled since Apollo 13 in 1970.
Historic Crew
The mission carries NASA astronauts Wiseman, Glover, Koch and CSA astronaut Hansen.
Koch will become the first woman to fly around the Moon.

The crew practiced piloting Orion in manual mode using ICPS as a stand-in for future dockings.
TechCrunch highlighted the pivot toward commercial partners for surface landings.
Free Return Trajectory
Orion is on a free-return trajectory designed to bring the crew back safely with minimal propellant use.
The path will carry the spacecraft around the far side of the Moon and back regardless of additional maneuvers.
This fail-safe design helped save Apollo 13's crew.
Public Engagement
NASA provided public tools including the Artemis Real-time Orbit Website with live tracking.
The mission garnered global media coverage recapping the historic moment.

Funding for the first two Artemis flights amounts to approximately $36 billion.
