NASA has pushed its first two crewed Artemis moon missions back to 2026 and 2027, and the move could have big ramifications.

NASA's Orion spacecraft recently completed an 11-month test campaign, during which it was subjected to extreme conditions of a launch abort scenario and electromagnetic effects of lightning strikes.

Though it isn't expected to launch until 2026 at the earliest, NASA is quietly preparing its SLS rocket for the Artemis II lunar mission.

Through NASA's Artemis campaign, astronauts will land on the lunar surface and use a new generation of spacesuits and rovers as they live, work, and conduct science in the moon's south pole region, exploring more of the lunar surface than ever before.
