NASA informs the project managers of the Galileo and Magellan interplanetary probes – both of which were due to be launched via space shuttle – that their planned launches are obviously off the schedule due to the destruction of space shuttle Challenger and her crew. Further changes in the shuttle program in the wake of the tragedy will have far-reaching effects, including the cancellation of propulsion modules that would have allowed, for example, Galileo to be put on a direct trajectory toward Jupiter. The Galileo mission plan will undergo significant changes, including the loss of a planned visit to asteroid 29 Amphitrite, and both missions will eventually begin from the cargo bay of space shuttle missions in 1989.
