12 lip 2022 · Humans have taken spiders into space more than once to study the importance of gravity to their web building and prey capture behaviors.
Two golden orb spiders are delivered by the STS-134 crew to the International Space Station so researchers can observe the arachnids' habits in microgravity.
The microgravity of space impacts everything from the human body to water, and after sending arachnid astronauts to the ISS, scientists found that goes for spider webs too!
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.
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 · 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.
