STS-61-F was a United States Space Shuttle mission planned to launch on 15 May 1986 using Challenger. It was cancelled after Challenger was destroyed earlier that year. he main objective of STS-61-F was to deploy the Ulysses solar probe, which would travel to Jupiter and use it as a gravitational slingshot in order to be placed into polar orbit around the Sun. This mission would have marked the first use of the Centaur-G liquid-fueled payload booster, which would also be used on the subsequent mission to send the Galileo probe in orbit around Jupiter.
