Artemis II Moon Rocket Heads Back to Launch Pad

NASA’s Artemis II SLS (Space Launch System) rocket and Orion spacecraft slated to ship 4 astronauts across the Moon started rolling to Launch Pad 39B at 12:20 am EDT on Friday, March 20. Rollout operations on the company’s Kennedy Space Center in Florida had been delayed earlier within the day due to excessive winds within the space.

The trek to the pad is anticipated to take up to 12 hours, as NASA’s crawler-transporter 2 fastidiously carries the rocket on prime of the cell launcher roughly 4 miles alongside the crawlerway. A reside feed of the rollout is out there onNASA’s YouTube channel.

Following a profitable moist costume rehearsal on Feb. 21, groups recognized a difficulty preventing helium from flowing to the rocket’s higher stage, prompting a return to the Vehicle Assembly Building (VAB) the place the problem was repaired.

While the rocket and spacecraft had been within the VAB, engineers additionally refreshed and retested a number of programs on the rocket. Engineers activated a brand new set of flight termination system batteries, changed different batteries on the higher stage, core stage, and stable rocket boosters, and charged Orion’s launch abort system batteries. Engineers additionally changed a seal on the core stage liquid oxygen feed line and reassembled and retested the oxygen tail service mast umbilical plate to affirm a good seal interface.

Artemis II will ship NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, together with CSA (Canadian Space Agency) astronaut Jeremy Hansen, on an roughly 10-day mission across the Moon and again, marking the primary crewed flightsof the Artemis program.
