Quick answer: Artemis II’s trip to the Moon is expected to take about 4 days each way , with the full mission lasting about 10 days total. NASA’s first Artemis mission, Artemis I, took 25 days, 10 hours, 53 minutes overall, but that was an uncrewed test flight with a very different profile.

Artemis II timing

For the upcoming crewed mission, the spacecraft is expected to travel from Earth to lunar vicinity in roughly four days , then loop around the Moon and return home.

Recent reporting also describes the full Artemis II flight as a 10-day journey around the Moon and back.

If you meant Artemis I

If you were asking about the earlier Artemis I mission, that mission lasted 25 days, 10 hours, and 53 minutes from launch to splashdown.

It traveled about 1.4 million miles in total during its uncrewed test flight.

Bottom line

  • Artemis II to the Moon: about 4 days.
  • Artemis II total mission: about 10 days.
  • Artemis I total mission: 25 days, 10 hours, 53 minutes.
