    WISA Woodsat

    Recently, the European Space Agency (ESA) has planned to put the world’s first wooden satellite, WISA Woodsat, on Earth’s orbit by the end of this year. 

    • The mission of the satellite is to test the applicability of wooden materials like plywood in spacecraft structures and expose it to extreme space conditions, such as heat, cold, vacuum and radiation, for an extended period of time.
    • It will be launched to space by the end of 2021 with a Rocket Lab Electron rocket from the Mahia Peninsula launch complex in New Zealand..
    • The satellite, designed and built in Finland, will orbit at around 500-600 km altitude in a roughly polar Sun-synchronous orbit. 
    • WISA Woodsat is a 10x10x10 cm nano satellite built up from standardised boxes and surface panels made from plywood, the same material that is found in a hardware store or to make furniture.
      • Designers have placed the wood in a thermal vacuum chamber to keep dry when it’s in space. 
      • They have also added a very thin aluminium oxide layer to minimise vapour coming from the wood and to protect it from erosive effects of atomic oxygen.

    Devendra Kula Vellalar Community

    Spider Ballooning

    Recently, the Gippsland region of Victoria state (Australia) has witnessed spiders spin webs stretching across trees, road signs and paddocks.

    • Heavy rains and floods have caused spiders to climb to higher ground using a survival tactic called “ballooning”.
    • Under the tactic, the insects throw out silk that latches on to vegetation, allowing them to escape.
    • Spiders, which can produce a wide variety of silks, produce this kind of web which is very thin and delicate, and allows them to fly away with the breeze, sometimes as far as 100 km.
    • Because this ballooning silk is lighter than air, it latches on to objects such as tree tops, tall grass and road signs, allowing the spiders to climb up.
    • Lakhs of spiders do this at the same time, creating “gossamer” sheets covering the wetlands.
    • The webs are expected to fade away towards the end of the week.
    • Victoria state generally sees this natural phenomenon during the winter, when it receives most of its rain.
    • The spiders which lay such webs are called “vagrant hunters”, which typically live on the ground and do not build a web.
      • Even while ballooning after a flood, each spider throws up only one thread.
