NASA is preparing to launch about 5,000 tardigrades (adorable chunky “water bears”) and 128 baby squid glowing in the dark into space.
The animals will head to the International Space Station (ISS) next week as part of SpaceX’s 22nd cargo supply mission.
SpaceX will launch a tiny creature on board the Falcon 9 rocket from the Kennedy Space Center in Florida at 1:29 pm (EDT) on June 3.
Relation: 8 Reasons to Like Tardigrades
Tardigrade With a small body length of only 0.04 inches (1 millimeter), its popular nickname comes from its fat bear-like appearance. Seen under a microscopeAnd these little guys can withstand extreme radiation. Six times the pressure found in the deepest part of the ocean. And the complete vacuum of the universe makes microscopic animals much stronger than animals of the same name. In fact, the Israeli spacecraft Beresheet Carry thousands of dried tardigrades It was on board when the landing attempt on April 11, 2019 failed and crashed on the moon. If the organisms were able to survive the collision, they would probably survive because they were in a resuscitable dehydrated “tun” state. ..
Astronauts make tardigrades a very useful research organism on the ISS, where astronauts want to identify specific genes involved in the amazing feat of teenage animals adapting to high-stress environments. These abilities to do. This should provide some important insights into the health effects of long-term space travel.
“The things that tardigrades can survive include drying, freezing, and heating above the boiling point of water. They can withstand thousands of times more radiation than we do. “There is no oxygen, which allows us to live for days or weeks with little energy,” said Thomas Boothby, assistant professor of molecular biology at the University of Wyoming and principal investigator of the experiment, in a news briefing. “They have been proven to survive and reproduce during space flight and can survive prolonged exposure to space vacuum.”
In Boothby’s study, astronauts examine the molecular biology of tardigrades for signs of immediate and long-term adaptation to life in cyclones.Earth Orbit — Bringing bold space travelers to zero rigor gravity And increased radiation exposure. He said that information gathered from creatures arriving at the station semi-frozen before thawing would provide essential insights into future therapies that could protect astronauts’ health during long-term space missions. I want it.
In addition, a separate parallel experiment, scheduled to be delivered by a supply mission, will bring baby Euprymna scolopes to the station. Inside the 0.12 inch (3 mm) squid, there is a special luminescent organ that emits bioluminescence. Bacteria Gives squid shine. Researchers in this experiment want to investigate this symbiotic relationship between bacteria and squid to see how beneficial microorganisms interact with animal tissues in space.
“Animals, including humans, rely on microorganisms to maintain a healthy digestive and immune system,” said a microbiologist at the University of Florida, Understanding Microgravity on Animal-Microbial Interactions (UMAMI). ) Jamie Foster, Principal Investigator of the Experiment, said. Said in a statement“It is not fully understood how space flight alters these beneficial interactions.”
Since squid is born without bacteria and bacteria are obtained from the surrounding sea, researchers plan to add bacteria to the squid as soon as the animals are thawed on the ISS. You can observe the establishment of symbiosis. By studying the molecules produced in the process, researchers will be able to identify which genes the squid turned on or off to achieve its feat in space. Knowing this. This will allow humans to better manage the gut microbiota and the microbiota of the immune system on long-distance space trips.
Traveling into space can be stressful, but Kumamushi has, at least recently, survived the shots of high-speed guns and endured worse conditions. In that study, researchers found that tardigrades could withstand impacts applied at speeds of approximately 3,000 feet per second (900 meters per second). As Live Science previously reported..
