This is fantasticThe rescue team wanted to park the vintage International Sun-Earth Explorer 3 spacecraft (ISEE-3), in a stable location between the Earth and the sun called L-1. But those attempts ended when controllers discovered there wasn't enough nitrogen pressurant left in the probe's tanks to help make course corrections.
Keith Cowing, co-leader of the ISEE-3 Reboot Project, told
Space.com, “We’re disappointed we couldn’t put it in the L-1 orbit, but we had a lot of scientists saying we’re more interested in interplanetary space,”
I wonder if NASA has other satellites out there which could be utilised in a similar fashion?
