NASA Targets March 6 for Historic Return to Moon After Successful Rocket Test

Successful Test Clears Path for Launch

NASA has set its sights on March 6 as the earliest launch date for Artemis II after successfully completing a critical fueling test of its massive Space Launch System rocket. Engineers loaded more than 700,000 gallons of liquid propellant into the rocket, sent a closeout crew to the launch pad to demonstrate closing the Orion spacecraft's hatches, and completed two runs of terminal count — the final phase of the launch countdown.

The achievement marks a significant milestone after NASA's first attempted wet dress rehearsal on February 2 exposed several issues with both the SLS and the Orion capsule, including hydrogen fuel leaks . At a press conference on Friday, NASA's Artemis launch director Charlie Blackwell-Thompson said the agency is confident it has fixed the leaks and that none arose during Thursday's fueling and mock launch countdown.

The four astronauts who will travel around the moon on this historic mission are due to enter quarantine on Friday, Feb. 20 , signaling NASA's confidence in the upcoming launch window. The potential Artemis II launch dates are now as follows: March 6, 7, 8, 9 and 11. April 1, 3, 4, 5 and 6.

First Human Moon Mission in Over 50 Years

Artemis 2 will be the first crewed mission to go beyond low Earth orbit since Apollo 17 back in 1972. The 10-day mission will carry NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, along with Canadian Space Agency astronaut Jeremy Hansen, on a free-return trajectory around the Moon and back to Earth.

Glover will become the first person of color, Koch the first woman, and Hansen the first person not from the United States to leave Earth orbit and to travel around the Moon. Artemis II is anticipated to break Apollo 13's record (248,655 miles) for the farthest distance humans have traveled from Earth. The Artemis II Orion spacecraft will travel over 4,000 miles beyond the Moon as it flies a loop around the Moon's far side.

The mission represents more than just a technological demonstration. The crew will fly by the far side of the moon (passing between 4,000 and 6,000 miles above it). The astronauts will spend the day observing and photographing the far side of the moon, parts of which have never been seen by human eyes, and then circle it for a return to Earth.

Testing Critical Systems for Future

During the mission, astronauts will travel thousands of miles beyond the moon, experience deep-space radiation, and test life-support, navigation and communications systems in real flight conditions. During this time the crew will perform various checkouts of the spacecraft's life support systems as well as an in-space rendezvous and proximity operations demonstration using the spent Interim Cryogenic Propulsion Stage (ICPS) as a target.

The return journey will push boundaries even further. Orion will re-enter Earth's atmosphere at approximately 25,000 miles per hour (40,000 km/h), the fastest reentry ever attempted. After re-entering the Earth's atmosphere, the Orion will splashdown off the coast of San Diego (weather and systems permitting) with the assistance of two sets of parachutes designed to slow it down to a safe speed of about 17 mph.

However, recent developments have introduced some uncertainty. A day after NASA said it was eyeing a potential March 6 launch date for the Artemis II lunar mission, the space agency now says new complications could derail all of the March launch dates. Just one day after NASA said it was eyeing a potential March 6 launch date for the Artemis II lunar mission, the space agency said Saturday that complications with the rocket could delay all launch attempts in March from the Kennedy Space Center in Florida.

Gateway to Mars and Beyond

The goal is to confirm that Orion, SLS, and mission operations can safely support astronauts in deep space before attempting a lunar landing on a future mission. Following the mission, engineers and flight controllers will spend months analyzing data to determine readiness for the next phase of Artemis. The next planned mission, Artemis 3, which will land on the surface of the moon in 2027, if all goes according to plan.

The broader Artemis program represents humanity's most ambitious space exploration effort since Apollo. Those astronauts, who NASA has said would be the first woman and the first person of color on the Moon, would spend almost a week in the Moon's south polar region, where frozen water may exist in permanently shadowed craters. Proposed lunar surface missions in the Artemis program include building a base camp at the lunar south pole, where astronauts could stay for one or two months.
