The Space Launch System, which is the world's most powerful rocket, will roll out on the launch pad today as Nasa begins plans to return humans to the Moon.
NASA has again delayed the final prelaunch test of Artemis I, an uncrewed mission that will be the stepping stone for returning humans to the Moon after several decades. The wet dress rehearsal was previously scheduled for February and has now been postponed to mid-March. This could now delay the actual launch of Artemis I to April or May.
ESA has for decades relied on its Russian and American counterparts to launch astronauts into space. Currently the agency has several places booked on American commercial launches.
