STS-9とは 意味・読み方・使い方

STS-9 (Space Transportation System 9, also known as STS-41A and Spacelab 1) was a NASA Space Shuttle mission which launched on 18 November 1983 and landed ten days later on 8 December. The mission carried the first Spacelab module into orbit to conduct space-based scientific experiments. It was the sixth mission of the Space Shuttle Columbia, and was Columbia's last flight until STS-61-C in early January 1986. It was also the last time the old STS numbering was used until STS-26 (in the aftermath of the Challenger disaster of STS-51-L). Under the new system, STS-9 would have been designated as STS-41-A.
