Heart Research and New Toilet Installation on Station Today

Cardiac research and orbital plumbing were the Monday highlights for the Expedition 64 crew aboard the International Space Station.

Flight Engineer Kate Rubins peered through a microscope at heart tissue samples today for the Cardinal Heart study. The microgravity study may provide new insights and advanced therapies for heart conditions on Earth and in space.

For the Vascular Echo experiment today, Flight Engineer Victor Glover strapped on a Doppler probe to his right leg to scan his femoral artery during a light exercise session. The cardiovascular study, running since March 2015 on the orbiting lab, is looking at how living in space stiffens the arteries.

A brand new, advanced toilet, delivered Oct. 5 on the 14th Cygnus resupply mission, is being installed on the space station today. NASA astronauts Michael Hopkins and Shannon Walker put on their plumber caps today to assemble and install the Universal Waste Management System in the Tranquility module. The station’s second space bathroom was designed to be better integrated with water systems, as well as smaller, lighter, easier to use and more comfortable.

In the Russian segment of the station, Commander Sergey Ryzhikov and Flight Engineer Sergey Kud-Sverchkov focused on cargo transfers and inventory updates. The duo is packing the Progress 76 resupply ship with trash and discarded gear for its departure from the Pirs docking compartment in February.

Early Saturday morning, an unexplained power glitch resulted in a loss of power to some International Space Station systems that are operated by one of eight power channels for the complex (4B channel). The crew was never in any danger, and the affected systems were repowered in a short period of time by one of the other station’s power channels (4A).

As of Monday morning, all impacted station systems are operating normally while flight controllers in Mission Control review data to try to assess the cause of the problem and a forward plan of remedial action.

The Expedition 63 crew started the workweek checking out hardware supporting life science, combustion research and ongoing Earth observations. A Russian cargo craft docked to the International Space Station is also being packed with old gear for disposal toward the end of the year. The multitude of microgravity research that takes place every day on the orbiting lab, requires regular maintenance and monitoring by the crew or scientists on the ground. The ongoing research supports innovative applications and insights benefitting Earth and space industries. Today, Commander Chris Cassidy serviced an advanced space microscope and swapped components supporting safe combustion investigations. Cassidy first configured the Light Microscopy Module , part of the Fluids Integrated Rack , which supports basic physics and biology research. Next, the veteran N

Thursday’s science schedule aboard the International Space Station focused primarily on DNA and physics research including ongoing Earth photography sessions. The Expedition 63 trio also maintained life support gear and packed a Russian cargo ship. The space environment affects a variety of biological and physical phenomena adapted and designed for Earth’s gravity and atmosphere. Organisms from microbes to humans experience a variety of critical changes in microgravity. Fuels, materials and a host of other physical conditions also go through a series of important modifications. NASA and its international partners study these effects to ensure the health of astronauts and safety of spacecraft planned for future missions to the Moon, Mars and beyond. DNA studies have been ongoing for years on the station to understand

Credit: NASA TV At 4:38 a.m. EST, Expedition 64  Flight Engineer Soichi Noguchi of the Japanese Aerospace Exploration Agency used the International Space Station’s robotic Canadarm2 to grapple the Northrop Grumman Cygnus spacecraft as Flight Engineer Michael Hopkins of NASA monitored Cygnus systems during its approach. Next, ground controllers will command the station’s arm to rotate and install Cygnus, dubbed the S.S.  Katherine Johnson , on the Earth-facing port of the station’s Unity module . NASA Television coverage of installation will begin at 6 a.m., and installation of the Cygnus spacecraft to the space station is expected to be completed later this morning. Cygnus will remain at the orbiting laboratory for a three-month stay. Watch live on the agency’s website or on the NASA app. Learn more about space station activi
