ScienceDaily: Spiders in Space: Researchers Observe Arachnid Habits in a Microgravity Environment

The very idea of spiders in space brings to mind campy, black and white horror films involving eight-legged monsters. In actuality, it is a scientific investigation called Commercial Generic Bioprocessing Apparatus Science Insert-05 or CSI-05, in which researchers observe arachnid habits in a microgravity environment. This is the second spider investigation on the International Space Station -- the first was CSI-03 -- and researchers have high hopes that the sequel will eclipse the original.

Scheduled to launch with STS-134, the spider habitat will transfer from the space shuttle Endeavour to the space station. Once aboard, the crew will place the two habitats into the Commercial Generic Bioprocessing Apparatus or CGBA. This equipment will maintain a consistent temperature, humidity and lighting cycle for the spiders and their sustenance supply of fruit flies. The CGBA also controls imaging for the investigation.

The spider pair currently planned for investigation with CSI-05 are both golden orb spiders (Nephila clavipes), which spin a three dimensional, asymmetric web. This is different from the two orb spiders (Larinioides patagiatus and Metepeira) that launched to the space station on STS-126, which were selected specifically for the symmetry of their web formation. Scientists are looking to see if and how the arachnids will spin their webs differently in microgravity. The results will help them to understand the behavioral role of gravity for the spiders and their fruit fly companions.
