Jim's development of the nickel-hydrogen battery was an important milestone in the development of spacecraft. After Burt Edelson left COMSAT Laboratories and went to NASA, he was reviewing the Hubble Space Telescope program. When he found that they were using an older battery design with a limited lifetime, Burt came to COMSAT for help in getting the nickel-hydrogen battery for use in the program. That's an important reason the the Space Telescope is still sending back useful photos.
