Artemis II rolls back to the pad after a helium fix, aiming for an April Moon launch

NASA’s Artemis II rocket is back on Launch Pad 39B at Kennedy Space Center, docking there at 11:21am on Friday 20 March, FOX 35 Orlando reports. The four-mile trip at roughly 1mph began after midnight, later than the planned 8pm Thursday start. The return follows a problem with helium flow in the rocket’s upper stage, which FOX 35 says was caused by a seal that has been fixed; technicians also adjusted the rocket’s flight batteries and the Orion capsule’s charging-system batteries. The crew entered quarantine in Houston on Wednesday 18 March.

Britain’s BBC Sky at Night Magazine traces the route here. A first wet dress rehearsal on 2 February ended with a hydrogen leak. A second one in late February confirmed that fix but found the helium problem, and the March window was scrubbed. On 25 February the rocket rolled back to the Vehicle Assembly Building to preserve an April date.

How each outlet framed it

• FOX 35 Orlando — the Space Coast view: the overnight crawl to the pad, the repairs and the launch times for each possible day.
• BBC Sky at Night Magazine — the stargazer’s guide: the full chain of delays and a window running from 27 March to 10 April, with NASA saying timing depends on “technical readiness and orbital constraints”.

Where the numbers differ: FOX 35 lists seven launch dates, 1–6 April and 30 April, with 1 April at 6:24pm; Sky at Night lists opportunities on 1, 3, 4, 5 and 6 April, leaving out 2 April.

What happened next: Sky at Night reports that Artemis II launched on 1 April at 18:35 EDT.
