During parachute descent, spacecraft use their Reaction Control System (RCS) thrusters to reorient themselves so that the most robust structural portion contacts the water first, ensuring a safe landing; the plumes observed in infrared cameras during descent are caused by these thrusters firing in short bursts to achieve the proper orientation.

🚀🌊 What were those mysterious plumes coming out of Artemis II right before splashdown?本站添加:
the spacecraft was descending under parachute. We saw on the infrared camera some plumes emanating from the vehicle that looked like either venting or thruster firing. Just wondering if you could speak a little to what the spacecraft was doing then, what exactly caused those plumes.
>> Imagine that's probably the spacecraft reorienting itself. We when we're on our main parachutes, we do a reorientation to ensure that the the most robust structural portion of the spacecraft contacts the water first. The plumes you were seeing were the crew module reaction control system thrusters firing.
>> Houston, Integrity splashdown sending post-landing command now.
>> Splashdown confirmed.
>> Copy splashdown. Waiting on VLDR.
>> Splashdown confirmed at 7:07 p.m.
Central Time, 5:07 p.m. Pacific Time.
From the pages of Jules Verne to a modern-day mission to the moon, a new chapter of the exploration of our celestial neighbor is complete.
Integrity's astronauts back on Earth.
