I have also noticed this. One in particular who I followed because they posted a bunch of really excellent astronomy photos and had an exuberance for space flight recently “got accepted” to “go to Mars” and now they “live on a faux mars base in an inhospitable climate” in order to “train for life on Mars.”

It’s unclear if it’s real or fake, but their “qualifications” seem to be number of social media followers, so it doesn’t seem actually real.

I’m not complaining, cool story and photos, but I’m sure it’s all performative so I follow it as one would a cool fiction podcast or something.
