Farthest Current Human Outpost Provides Unique Insight and Ongoing Scientific Advancement

Following CRS-20, final contracted commercial resupply mission of the first generation SpaceX Dragon, ~1,815 kg of cargo – much of which consists of science projects now undergoing analysis – has returned to Earth. Researchers involved in the NASA Ames BioNutrients investigation, concerned with in-space nutrient cultivation utilizing beta-carotene producing yeast cultures, measure growth rates of 4th sample return – reaching 1-year point in 5-year experiment. The Space Biofilm study also received samples for analysis from CRS-20. Conducted by NASA, DLR, UC Boulder, MIT, Universidad del Valle de Guatemala and Saarland University, the Space Biofilm team works to describe the nature of organic accumulations on spacecraft surfaces, both interior and exterior – an issue of great importance for achieving homeostasis in artificial environs. ISS resident Jessica Meir and Andrew Morgan offer advice from space on coping with isolation, as they prepare to return to a world changed by Covid-19: exercise and telecommunication with loved ones are among their recommendations for maintaining normalcy. In a video message posted to Twitter, Meir and Morgan demonstrate space exercises utilizing Advanced Resistive Exercise Device (ARED) and more familiar options such as stationary biking, treadmill ...
