Then-Senator Jake Garn flew on Shuttle mission STS-51-D in April 1985. He developed the worst documented case of space adaptation syndrome, for which an informal unit of space sickness was named after him:

The space sickness he experienced during the journey was so severe that a scale for space sickness was jokingly based on him, where "one Garn" is the highest possible level of sickness. Some NASA astronauts who opposed the payload specialist program, such as Mike Mullane, believed that Garn's space sickness was evidence of the inappropriateness of flying people with little training.

What is the earliest known use of this unit?

(No need for official sources; personal recollection of those involved in the Shuttle program is fine.)

  • $\begingroup$ For point of reference, I can't find any mention in Google books prior to 2000. Everything I can find online or in Google books after 2000 refers to it as a unit already in existence and recounts the original Garn story but does not mention any specific instance that the unit was used. $\endgroup$ – called2voyage Jun 12 at 17:31

  • $\begingroup$ I remember hearing some stories around the Office, probably in the ~1998 time frame, that the second-highest Garn level ever achieved, to that point, registered no more than a few milli-Garns... $\endgroup$ – Digger Jun 13 at 15:05
