Artemis 1 intends to launch an uncrewed spacecraft toward the moon later this year and has an upcoming "wet dress rehearsal" scheduled for late February. A simulated countdown will ensure the Orion spacecraft and Space Launch System (SLS) rocket are working as expected. The Orion spacecraft has flown only once before, and the Artemis 1 launch will mark the SLS rocket's first flight.

Since the new year, engineering tasks have readied the spacecraft, with the crew access arm for the Orion spacecraft being tested successfully on January 11th. The SLS also completed core stage engineering tests by January 14th, after replacing one of its four RS-25 engine controllers.

The team will conduct a second countdown sequencing test to demonstrate the ground launch software and ground launch sequencer, which checks for health and status of the vehicle while at the pad," said NASA in a mission update.

After the countdown test and final closeouts are complete, SLS and Orion will head to the launch pad for the first time to complete the wet dress rehearsal test," said NASA.

More updates on the progress of the Artemis 1 mission are available on NASA's website.
