On a lighter note, being curious why they italicized Challenger and Columbia but not Apollo 1, I found this, which I had not seen before: https://history.nasa.gov/styleguide.html

> Italics: All orbiter names should be capitalized [0] (e.g. Atlantis, Columbia, Discovery ). We also italicize lunar module and command module names (e.g. Eagle, Columbia, Odyssey, Aquarius). We do not italicize mission names (STS-44, Apollo 11). All ships should be italicized (e.g. the Hornet, the Enterprise). We do not italicize the names of probes and robotic spacecraft (e.g. Voyager, Cassini).

[0] I think "capitalized" is a typo here that should be "italicized".
