Arabella and Anita had the right stuff--namely, silk for spinning webs. These two ordinary spiders were NASA’s first eight-legged astronauts! Anita and Arabella got their mission because a high-school student named Judy Miles wondered if spiders could spin webs in a weightless environment. She suggested sending spiders into space to find out. NASA space scientists liked her proposal and went to work designing special cages, lights, and cameras.

In 1973, Arabella and Anita blasted off into space for the Skylab 3 mission. On her first day in orbit, Arabella didn’t do well. She spun sloppy webs and obviously felt the effects of weightlessness. However, by her third day in space, she was spinning just as though she were back at home. Her webs were finer in space, which was expected. But the pattern remained the same. She proved that spiders can spin earthly webs in space.

Though Arabella and Anita have both died, their bodies remain at the Smithsonian, memorialized for their small, vital part in increasing our knowledge of space.
