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.
26 maj 2011 · 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.
11 gru 2020 · In the 2011 spiders-in-space experiment, researchers studied webs the spiders spun both with and without light, and watched how the spiders oriented themselves. Webs woven in darkness turned out to be symmetric, while those built while the habitat was illuminated from the top had the same asymmetric shape as those seen on Earth.
The free Spiders in Space Teacher’s Guide provides instructions for setting up ground-based spider habitats and helping students to design their own experiments. We invite you to use these resources and compare the behavior of spiders on Earth to that of Esmeralda and Gladstone during their travels in space.
11 gru 2020 · TORONTO -- 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 · A hundred of these webs were then analyzed in 14,500 images to see how those grown in the microgravity environment of space compared to those built on Earth. Many of the webs built a few...
