On the road again. NASA’s Space Launch System (SLS) rocket with the Orion spacecraft atop has arrived at Launch Pad 39B at @NASAKennedy Space Center in Florida in preparation for a final test before the @NASAArtemis I Moon mission. Stacked on the mobile launcher and mounted on the crawler-transporter, it took 10 hours and 28 minutes for SLS and Orion to travel four miles, or 6.4 kilometers, from the Vehicle Assembly Building to the launchpad. The trip began at 5:47 p.m. EDT Thursday, March 17, and the 322-foot (98-meter) tall, 3.5-million-pound (1.6-million-kg) rocket and spacecraft arrived at the pad at 4:15 a.m. EDT on March 18. During the upcoming final test, known as the wet dress rehearsal, the Artemis I launch team will practice loading and unloading propellant into and from the rocket’s tanks and run through a full launch countdown. The uncrewed #Artemis I mission will lead the way for missions to land the first woman and first person of color on the Moon.
