I have not looked at the novel and therefore do not have any comment on that particular item being included or excluded from the NASA website.
However, considering the "anti-DEI" aspects of this and other recent changes in official policy, I do want to say that I support the inclusion of women in space.
Certainly, if we are to "colonize" anywhere off Earth, women will be a necessity.
But, even before that, (on average) women have somewhat different perspectives than men on social and world order issues. They can be well suited to teamworking and coordination on missions.
And, of course, they have different biology than men in several parameters, so learning how their bodies react to conditions of space flight is necessary, too.
For that reason, I think NASA has a legitimate scientific interest for recruiting women into the astronaut corps as well as employing them in supporting roles.
My own experiences working with women in STEM and in leadership roles has been positive in most cases. Of course, every group has its bad apples, but those don't define their groups.
