SpaceX halted Falcon 9 launches for a week while it investigated that issue, which was traced to a fuel leak in one of the booster's nine Merlin engines. This leak led to a fire shortly after touchdown, which weakened a landing leg and caused the vehicle to tip over.

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.

Mankind’s leap back to the moon will have to wait at least a month more after a final Artemis II launch rehearsal revealed critical fuel leaks in the mission’s giant rocket. The Artemis II launch won’t happen until at least March after Monday’s “wet dress rehearsal” found the Space Launch System rocket was leaking liquid hydrogen as the fuel was pumped through its systems.

CAPE CANAVERAL, Fla. (AP) — NASA’s dress rehearsal for its mega moon rocket is off until at least this weekend because of a pair of technical problems that kept stalling a fueling test. Launch managers tried twice — once Sunday and again Monday ...

The H3 is a relatively new vehicle, with last month’s launch marking the eighth flight of Japan’s flagship rocket. The launcher falls on the medium-to-heavy section of the lift spectrum. The eighth H3 rocket lifted off from Tanegashima Island in southern Japan on December 22, local time, carrying a roughly 5-ton navigation satellite into space.

Nasa delays its return to the Moon after problem during testing - NASA says it is now targeting a March launch for its new moon rocket after encountering fuel leaks during a crucial test
