Skylab was the United States' first space station, launched by NASA in 1973 and occupied for 24 weeks between 1973 and 1974. It was manned by three crews and included a solar observatory and Earth observation equipment.
Skylab conducted numerous experiments before disintegrating in the atmosphere in 1979, with debris landing in the Indian Ocean and Western Australia. https://en.wikipedia.org/wiki/Skylab

@MegaMichelle@a2mi.social This appears less red than it would to your eyes. From the source page, "It has been white-balanced so the colors of the rock materials resemble how they would appear under daytime lighting conditions on Earth."
This article has more information on this and an example of how it would look in person https://www.jpl.nasa.gov/images/pia16800-raw-natural-and-white-balanced-views-of-martian-terrain
