2. SLS Rocket Rollout & Testing:
* The Artemis II Space Launch System (SLS) rocket reached launch pad 39B after an eight-hour, four-mile journey from the Vehicle Assembly Building (VAB).
* The next few weeks will be dedicated to tests and checkouts.
* A critical “wet dress rehearsal” is planned for around February 2nd, involving loading nearly 800,000 gallons of super-cold liquid hydrogen and oxygen.
3. Launch Director’s Comments:
* Launch Director Charlie blackwell-Thompson explained the initial steps at the pad involve connecting systems and validating connections to the firing room.
* She emphasized that the “wet dress rehearsal” is the most crucial test at the pad and a key driver for the launch date.
* Much of the testing has already been done offline or in the VAB, so the pad testing focuses on interfaces.
4. Image Caption:
* The image shows the SLS rocket at pad 39B.
* NASA aims to launch the rocket in early February to send four astronauts on a flight around the moon.
5. past Issues:
* The first SLS rocket flight in 2022 experienced delays due to problems with propellant loading.
