Nasa's Artemis 1 Mega- This Weekend for Launch

Rocket Faces a Huge Test

The Space Launch System (SLS)

 rocket that will fly NASA's Artemis 1 moon mission is at the pad for a critical series of tests this weekend.

NASA officials held a

 call with reporters on Wednesday (June 15) to give an update ahead of those tests

Which together comprise

 a launch simulation known as a "wet dress rehearsal."

The Artemis 1 stack — the SLS

 and an Orion crew capsule — was rolled out to the historic Launch Complex 39B at NASA's Kennedy Space Center (KSC) in Florida on June 6.

Mission teams have since completed

 ground communication validations leading up to the wet dress, which is scheduled to begin on Saturday (June 18).

Artemis 1 will be the

first launch for the SLS and will send an uncrewed Orion around the moon and back.
