NASA has announced the final test before an Artemis II launch date. Here's what to expect from this weekend's wet dress rehearsal.

Engineers are getting ready to put the pressure on hardware for the world’s most powerful rocket, NASA’s Space Launch System, as part of a rigorous test series to ensure each structure can withstand the incredible stresses of launch. SLS and the agency ...

On Monday, after rolling the SLS rocket to be used for the Artemis II mission to the pad in January, NASA attempted its first wet-dress test with this new vehicle. At one of the main interfaces where liquid hydrogen enters the vehicle, a leak developed, not dissimilar to problems that occurred with the Artemis I rocket three years ago.

Initially, it was hoped that the Artemis II mission to send astronauts slingshotting around the Moon could take place as early as Feb. 8. If all had gone well in this latest wet dress rehearsal, that may well have been the date.

The SLS wet dress rehearsal is the rocket's last major hurdle before launch.

NASA is planning an uncrewed test flight for NASA's Artemis program — which aims to return humans to the Moon. The uncrewed Artemis I mission will be the first flight of the agency's Space Launch System (SLS) super heavy-lift rocket and the first flight ...

NASA is just days away from its first chance to launch Artemis 2, the first astronaut mission to the moon since 1972, and will attempt a critical test for the lunar flight on Monday, Feb. 2. Ahead of the first launch window for Artemis 2,
