A test of NASA's towering Space Launch System rocket uncovered another issue with the vehicle meant to launch astronauts on a mission around the moon.

NASA will attempt to fuel its Artemis II rocket again tomorrow after hydrogen leaks derailed the first wet dress rehearsal and delayed what is scheduled to be a historic crewed flight around the moon.

Launch teams at NASA are hoping dangerous fuel leaks have been resolved as another practice launch countdown is happening for its Artemis II mission, which will eventually send astronauts around the moon.

NASA is moving one step closer to its next crewed lunar mission as the agency prepares to conduct a wet dress rehearsal for Artemis II.

The first crewed mission of the Artemis program won’t land on the moon, but it aims to take four astronauts farther from the Earth than anyone has gone before.

Before the four astronauts of the Artemis II mission launch into space, the crew must complete NASA's two-week Health Stabilization Program.

This is a step, if presently halting, toward future lunar missions and a long-term human presence on our companion world, one so important that even SpaceX is setting aside Mars for a greater focus on the moon and Blue Origin is setting aside suborbital space tourism for the same.
