KENNEDY SPACE CENTER, FL – After over 4 hours of delays due to continuing high winds all day Thursday, March 19 that stretched into Friday, March 20, NASA at last completed the 2nd rollout of  the agency’s Artemis II SLS Moon rocket and Orion spacecraft from the Vehicle Assembly Building (VAB) back out to launch pad 39B at NASA’s Kennedy Space Center.

The exciting rollout took place after a few weeks of necessary and critical repairs on the rocket inside the VAB to fix the helium flow clog that scrubbed plans to launch the rocket in early March.

Launch of Artemis II is targeted for as early as Wednesday, April 1.

The early April launch window includes a total of six opportunities every day through Monday, April 6.

The 4-mile trek at max speed of ca 0.8 mph takes about 12 hours as the Crawler-Transporter-2 (CT-2) moves the 11 million pounds mass stack of SLS and Orion secured to the mobile launcher from the VAB to top of pad 39B at KSC

NASA’s SLS (Space Launch System) and Orion spacecraft mega moon rocket for the Artemis II crewed moonshot mission completed its rollback from launch pad 39B into the VAB  where it arrived inside late evening Feb. 25, at NASA’s Kennedy Space Center in Florida – to fix the helium flow interruption issue detected in the ICPS upper stage during testing overnight Feb. 21 at Launch Complex 39B.
