Artemis II is a planned crewed mission by NASA that aims to orbit the Moon. It is part of the Artemis program, which seeks to return humans to the lunar surface and establish a sustainable presence there. The mission will use the Orion spacecraft and is expected to launch in the mid-2020s. The primary goal of Artemis II is to test the systems and capabilities of the Orion spacecraft with astronauts on board. This mission will pave the way for future lunar landings, including Artemis III, which aims to land astronauts on the Moon's surface.
