Space Station Science Heads Back to Earth!

Science experiments that are literally out of this world will be coming back to Earth on January 13th!  It's the first journey of it's kind since the space shuttle era ended, bringing microgravity research home from the International Space Station. “I am excited to finally see science returning here again because we can get these time sensitive experiments into the lab faster than ever,” says Kennedy Space Center utilization project manager Jennifer Wahlberg.  “Sending science up to space and then receiving it again on the runway was definitely something in the shuttle days that we really took pride in, and being able to rejoin that process is great.” The upgraded version of SpaceX’s Cargo Dragon spacecraft, Dragon 2, is seen atop a Falcon 9 rocket on Dec. 2, 2020, as they prepare to be rolled out to Launch Complex 39A at NASA’s Kennedy Space Center in Florida for the company’s 21st Commercial Resupply Services (CRS-21) launch.  The first launch for SpaceX under NASA’s second Commercial Resupply Services contract, CRS-21 will deliver critical supplies, equipment, and material to support a variety of science and research investigations that will take place aboard the International Space Station. Liftoff is scheduled for 11:39 a.m. EST on Saturday, Dec. 5.  CREDIT:  NASA On Jan. 12, the SpaceX cargo Dragon spacecraft undocked from the International Space Station and is en route for splashdown off the coast of Florida on January 13.  According to NASA, this will be the first space station cargo capsule to splash down off the coast of Florida, transporting significantly more science back to Earth than possible in previous Dragon capsules. https://twitter.com/i/status/1348995436950953987 The Space Station experiments cover a wide-variety of topics including Cardinal Heart, Space Organogenesis, Bacterial Adhesion and Corrosion, Fiber Optic Production, and Rodent Research-23.   “Rodent Research-23 was designed to start studying rodent gravity readaptation responses as quickly as possible, making it an ideal candidate for this flight,” said Jennifer Buchli, deputy chief scientist for the International Space Station program at NASA’s Johnson Space Center in Houston.

The samples will be sent all over the world to be analyzed and studied including and also in record time.
