First spider web in space
Arabella and Anita
Not Applicable ()

Arabella and Anita, two female cross spiders (Araneus diadematus), were sent into space in 1973 on the Skylab 3 mission to the US Skylab space station. The experiment, to see how spiders would spin webs in weightlessness, was suggested by Judy Miles, a US student. While the spiders did indeed construct normal looking webs, the silk was finer than on Earth, and with differences in thickness, unlike terrestrial spider silk, which has uniform thickness.
