STS-41-B was the tenth space shuttle mission, and the fourth flight for Challenger. Following STS-9, the flight numbering system for Space Shuttle missions was changed. Thus, the next flight, instead of being designated STS-11, became STS 41-B. STS-10 was cancelled due to payload delays.

The new numbering system was designed to be more specific in that the first numeral stood for the fiscal year offset into the shuttle program, the "4" being 1984. The second numeral represented the launch site; 1 for KSC, and 2 for Vandenberg AFB, Calif. (the latter was never used). The letter represented the order of launch assignment, "B" was the second launch scheduled in that fiscal year. (Following the Challenger accident, NASA reestablished the original numerical numbering system. Thus the only numbers according to this scheme were 41, 51, and 61. The first flight following STS-51-L is STS-26. If the numbering scheme had been kept, then the fourth flight in FY 1997 would have been 171-D, for example.)
