NASA is gearing up for the launch of the Artemis II mission, which will send four astronauts on a historic journey around the moon. The 32-story Space Launch System rocket is set to blast off on Wednesday evening, marking humanity's first launch to the moon in 53 years. After a day in orbit around Earth, the Orion capsule will propel the crew to the moon and back in a nearly 10-day flight that will end with a splashdown in the Pacific Ocean.

Why it matters

The Artemis II mission is a crucial step in NASA's Artemis program, which aims to return humans to the lunar surface and establish a sustainable presence on the moon. This flight will test the capabilities of the Orion spacecraft and pave the way for future Artemis missions, including the planned Artemis III landing that will put the first woman and first person of color on the moon.

The details

The Artemis II rocket has undergone a series of repairs and modifications after being grounded in February due to hydrogen fuel leaks. The latest issue, a clogged helium pressurization line, has been resolved, and the rocket is now ready for launch. The four-person crew, which includes two NASA astronauts, a Canadian astronaut, and a European Space Agency astronaut, arrived at the launch site on Friday.

  • The 2-day countdown for the Artemis II mission began on Monday.
  • The launch is scheduled for Wednesday evening.
