26 gru 2020 · 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 simple: on Earth, spiders build asymmetrical webs with the center displaced towards the upper edge.
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.
11 gru 2020 · Here on Earth, spiders are known to build their webs in all kinds of lighting and lack of lighting conditions. In general, those webs have the highest density area – that bulls-eye of concentric rings we call the center – actually off-center and located higher up in the web.

9 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...
11 gru 2020 · A team of scientists from Switzerland and the United States say that spiders are able to use light to orient themselves while weaving their webs in the absence of gravity in space.
10 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.
