Orion began the first human return journey from the Moon since Apollo 17 in December 1972 when it crossed the lunar sphere of influence at 1:25 PM EDT today. Three return trajectory correction burns are scheduled across Days 7 to 9, beginning with today's automatic firing during crew rest. Two earlier outbound burns were cancelled , because the trajectory was already inside tolerance, banking propellant the spacecraft may yet need for re-entry alignment.1
The return leg is a different navigation problem from the outbound. The 17.5-second third outbound burn established a baseline for how tightly the OMS-E (Orbital Manoeuvring System Engine) is trimming. The closest approach of 4,067 miles is now behind the crew.
The NASA OIG found the HLS (Human Landing System) Starship contract at least two years behind schedule , which makes Artemis II the final Orion-era test before the redesigned Artemis III LEO lander demonstration.2 Every return-phase data point now informs that redesign.
Splashdown on 10 April at 8:07 PM EDT will be followed by a post-recovery press conference at 10:35 PM EDT.34 The USS John P. Murtha sails from Naval Base San Diego.
