26 gru 2020 · Humans have taken spiders into space more than once to study the importance of gravity to their web-building. What originally began as a somewhat unsuccessful PR experiment for high school students has yielded the surprising insight that light plays a larger role in arachnid orientation than previously thought.
14 gru 2020 · The two spiders which were sent to space were quite hardy in their new gravity-free homes: The male survived zero gravity for 65 days and was still alive after returning to Earth, while the female built 34 webs and moulted three times – both of which are space records.
The spider experiment by the US space agency NASA is a lesson in the frustrating failures and happy accidents that sometimes lead to unexpected research findings. The question was relatively...
10 gru 2020 · Before long, webs built by the spiders grew haphazard, as the two arachnauts got in each other’s way. Fruit flies grown as food for the spiders in space also reacted to their unusual...

9 gru 2020 · When resting, spiders sit with their head downwards because they can move towards freshly caught prey faster in the direction of gravity. But what do arachnids do in zero gravity?
study houses the two spiders in separate habitats and includes chambers for their food supply of fruit flies. Artificial light simulates day and nighttime, as well as temperature and humidity...
