Artemis II Completes Translunar Injection and Midpoint Transit
Tap title to read story
Houston — NASA’s Artemis II crew conducted a translunar injection burn on April 2 that placed the Orion spacecraft on a trajectory around the Moon during the 10-day mission, following a go/no-go decision and a 5-minute, 50-second main engine firing of the ESA-provided service module.
The crew proceeded to configure Orion on Day 3 and reported minor onboard issues while mission control monitored systems; by about two days, five hours after liftoff the spacecraft passed the halfway point at roughly 219,000 km, with lunar sphere-of-influence entry scheduled for flight day five.

Why it matters
This mission is a big step for space exploration. It's part of NASA's plan to return humans to the Moon. That could lead to more scientific discoveries. And it might even pave the way for future Mars missions.
