Orion Capsule Begins Journey Back to Earth Tonight – IT Pro – News

Lost in translation. If you look at the original article linked to:

The thrusters were able to burn for 95 seconds instead of the usual duration of just 17 seconds or less

There is no “normal” burn time. During this mission, those particular missiles never burned for more than 17 seconds.

For example, NASA wants to find out how opening and closing a particular valve affects certain parts of the spacecraft

This is really not possible! “a” valve, “influence”, “some parts”…. It appears from the original article that this is a valve of the pressure control system, in which a small leak appears to have been detected. By opening and closing that valve, they want to see if that leak is going down.

and whether the spacecraft can hover on a closer clear course

The original article shows that this is an attitude control mode where instead of controlling about six axes, orientation is controlled in three axes.

A few days later it was announced that the capsule had traveled more than 432,210 km in space since its launch.

And this was also wrong in an article a few days ago on Artemis I: the spacecraft did not travel 432,210 km. This is the distance between the Earth and Orion, in a straight line. The total distance traveled is irrelevant unless it clearly indicates which reference frame you are using.
