In 1973, NASA sent about two spiders into space to test web-building without gravity; within days, they adapted and spun complete webs in orbit

Two spiders, Arabella and Anita, flew on Skylab 3 to test web-building in space. Initially disoriented, the spiders eventually adapted to the weightless environment. Their webs in space differed from those constructed on Earth. Astronauts provided additional food and water, and even altered Arabella's web. A student's curiosity led to this significant experiment about biological adaptation.
