<\/a>Six humans from three countries will ring in the new year 16 times tonight from an average altitude of about 260 miles above the Earth’s surface. Before the Expedition 61<\/a> crew goes to bed tonight and relaxes on New Year’s Day, they are researching critical space science to benefit humans on and off Earth.<\/p>\n Fire safety is extremely important and even more so aboard a spacecraft. Flight Engineer Jessica Meir<\/a> of NASA got to work using the Microgravity Science Glovebox<\/a> and observed how different fabric and acrylic samples burn in microgravity. Space fires<\/a> spread differently in confined spaces of different shapes and sizes. Scientists will use the data to improve products and procedures to save lives on the ground and in space.<\/p>\n A bone densitometer<\/a> that images and measures the bone mass of mice living in space is being calibrated today. NASA astronaut Andrew Morgan<\/a> checked out the sensitive device to ensure accurate measurements. Morgan then switched from biology hardware to tiny satellites and tested formation flying using algorithms programmed in to the free-flying SPHERES<\/a>.<\/p>\n NASA Flight Engineer Christina Koch<\/a> is loading the SpaceX Dragon<\/a> resupply ship today before it departs the International Space Station<\/a> on Jan. 5. She was measuring the mass of gear returning to Earth using an acceleration device<\/a> that follows Newton’s Second Law of Motion (force equals mass times acceleration).<\/p>\n Commander Luca Parmitano<\/a> of ESA (European Space Agency) reconfigured a specialized incubator<\/a> that uses a centrifuge to mimic different gravity environments for biology research. Afterward, he installed new components in a life support system that removes carbon dioxide from the station’s atmosphere.<\/p>\n Cosmonauts Alexander Skvortsov<\/a> and Oleg Skripochka<\/a> kicked off the last day of 2019 with housecleaning and computer checks. In the afternoon, the duo set up radiation detection gear<\/a> and serviced Russian life support hardware.<\/p>\n<\/div>\n Get The Details…<\/a><\/p>\n Mark Garcia <\/p>\n Powered by WPeMatico<\/a><\/small><\/p>\n","protected":false},"excerpt":{"rendered":" Six humans from three countries will ring in the new year 16 times tonight from an average altitude of about 260 miles above the Earth’s surface.
