Roberta Goodman

Roberta "Bobby" Smith was a human archaeologist from 30th century Earth.

When she was in her twenties, she was based at Survey Four on the Moon. The team were primarily there to search for minerals and ores to supplement Earth's shortage but Bobby's presence was requested by the Bureau of Alien Technology in case any alien technology was discovered.

It turns out, however, that her presence was necessary as the Eternity Crystal was discovered beneath the surface of the Moon.
