It’s Black Hole Friday!

What is a black hole? A black hole is an astronomical object with a gravitational pull so strong that nothing, not even light, can escape it.

The seven-member Expedition 64 crew from the United States, Russia and Japan will take the day off on Thanksgiving before ending the week with a day full of microgravity research. In the meantime, the crew spent Wednesday on a wide array of space science while getting the International Space Station ready for an upgraded SpaceX Dragon resupply ship.
NASA Flight Engineers Kate Rubins and Shannon Walker worked throughout Wednesday readying the station’s Tranquility module for a new commercial airlock from NanoRacks. Dubbed Bishop, the airlock will be delivered on the next SpaceX Dragon cargo mission targeted to launch on Dec. 5. The Bishop airlock will enable private industries to increase research opportunities in the vacuum of space.
Planned for Dec. 6, this will be the first automated docking of the Cargo Dragon to the space-facing port on the Harmony module. Previous Cargo Dragon vehicles were captured with the Canadarm2 robotic arm maneuvered by astronauts. Robotics controllers then took over and remotely installed Dragon to Harmony’s Earth-facing port.
The GRASP human research experiment, sponsored by the European Space Agency (ESA), was back on the science schedule Wednesday. Flight Engineers Michael Hopkins and Victor Glover wore virtual reality goggles and responded to virtual stimuli to help doctors understand how the central nervous system, specifically hand-eye coordination, adapts to weightlessness.
JAXA astronaut and Flight Engineer Soichi Noguchi started his day servicing the Kibo laboratory module’s Cell Biology Experiment Facility, a specialized incubator that can generate artificial gravity. Later, he joined Kate Rubins and examined her eyes using optical coherence tomography.
The orbiting lab’s two cosmonauts, Commander Sergey Ryzhikov and Flight Engineer Sergey Kud-Sverchkov, continued studying ways to make space workouts more effective. The duo later joined Rubins and practiced chest compressions, or cardiopulmonary resuscitation, in the event of a medical emergency aboard the space station.

NASA commercial cargo provider SpaceX is targeting 11:39 a.m. EST Saturday, Dec. 5, for the launch of its 21st commercial resupply services (CRS-21) mission to the International Space Station from Launch Complex 39A at the agency’s Kennedy Space Center in Florida.

Human research was the prime area of study today aboard the International Space Station. Results are helping NASA and its international partners keeps astronauts safe and healthy on long term space missions.
Flight Engineers Michael Hopkins and Victor Glover took turns today exploring how weightlessness impacts their hand-eye coordination. The GRASP study, sponsored by the European Space Agency (ESA), explores how microgravity affects a crew member’s central nervous system. That experiment has been under way at the orbiting lab since 2016, providing researchers critical data and insights on how astronauts adapt to living and working in space.
Commander Sergey Ryzhikov and Flight Engineer Sergey Kud-Sverchkov, the two Expedition 64 cosmonauts, participated in a Russian exercise study today. The duo worked out on a treadmill in the Zvezda service module while attached to a variety of sensors. Observations could lead to improved crew training techniques and more effective work outs on the way to the Moon, Mars, and beyond.
NASA Flight Engineer Kate Rubins readied an external exposure experiment this morning that will be placed outside Japan’s Kibo laboratory module. Afterward, she resumed her work exploring the behavior of water droplets that may lead to more advanced fuel and life support systems.
Japanese astronaut Soichi Noguchi, on his third space mission, set up hardware for a fiber optics study then organized stowage space in the Kibo lab. Flight Engineer Shannon Walker of NASA spent most of Tuesday on maintenance servicing spacesuit batteries and working on stowage tasks in the Tranquility module.
