3rd june, NASA will send 128 glow-in-the-dark baby squids and some 5000 tardigrader ( water bears) to the International Space Station for research purposes.
The water animals, which will be lanched aboard SpaceX’s 22nd cargo resupply mission to the IIS. Are part of experimantals that could help Scientists design improved protective measures for astronauts going on Long-duration space travel.
- why on IIS –
A space station is essentially a large spacecraft that remains in low-earth orbit for extended periods of time. Its like a large laboretory in space, and allows astronauts to came aboard and stay for weeks or months to carry out experiments in microgravity. The international space station has been in space science 1998, and has been known for the exemplary cooperation between the five participating space agencies that run it : NASA (United State), Roscosmos(Russia), JAXA(Japan), EAS(Europe), and CSA(Canada).For over 20 years since its launch, humans have continuously lived and carried out. Scientific investigations on the $150 billion ISS under microgravity conditions. Being able to make breakthroughs in research not possible on earth. As per NASA, the floating laboretory has hosted more then 3000 research and educational investigations from researchers in 108 countries and areas, Carrying out cutting edge research in various disciplines, including biology, human physiology, and physical, material ans space science.
- Why are the sea animals needed at the ISS?
The water bears and bobtail squid will be involved in experimantals aboard the floating laboretory, will be arriving in the semi–frozen state, befor the are thawed out
revived and grown in a spacial bioculture system. One of these studies involves looking at how water bears- tiny animals (around 1 mm) that can adapt to extreme conditions
on Earth, including high pressure, temprature and radiation would behave in a spaceflight environment.
- What is water bears?
Tardigrades Known Colloquially as water bears or moss piglets are a phylum of eight-legged segmented micro animals. They were first described by the German Zoologist Johann August Ephraim Goeze in 1773, who called them “little water bears“. They have been found everywhere in earth’s biosphere, from mountaintops to the deep sea and mud volcanoes, and from tropical rainforests to the antarctic. Tardigrades are among the most resilient animals knows with individual species able to survive extreme conditions. Researchers will be able to study their hardiness close up, and possibly identify the genes that allow them to become so resilient. By learning how the water bears can survive in low gravity conditions, it would be possible to design better techniques to keep astronauts healthy on long duration space missions.
