Human Research Revealing Space Impacts as Spacewalk Preps Gear Up

The Expedition 60 crew kicked off the workweek exploring stem cells and testing the printing of human tissue on the International Space Station. The astronauts are also gearing up for a spacewalk planned for next week.

Operations continue inside the orbiting lab’s new BioFabrication Facility today. Astronaut Nick Hague printed more human tissue samples Monday and stowed them in an incubator to observe and promote their cellular growth.

Flight Engineer Luca Parmitano of the European Space Agency set up the Life Science Glovebox in the Kibo laboratory module and researched the properties of stem cells. The space-based Micro-15 experiment is helping scientists understand stem cell differentiation better than ground-based studies. Results may provide therapeutic insights into ailments affecting humans on Earth and in space.

Early this morning, Parmitano joined NASA astronaut Andrew Morgan for hearing tests. Scientists are measuring how the microgravity environment and the acoustic levels of the station affect a crewmember’s hearing before, during and after a mission.

Morgan then partnered up with astronaut Christina Koch in the afternoon to configure spacewalking tools and spacesuit components. Morgan will follow lead spacewalker Nick Hague out of the Quest airlock hatch on Aug. 21 for a six hour and 30 minute spacewalk. The duo will install the International Docking Adapter-3 designed to receive new commercial crew vehicles from Boeing and SpaceX.

Cosmonauts Alexey Ovchinin and Alexander Skvortsov spent their morning learning how the gastrointestinal system adapts to long-term spaceflight. The duo performed ultrasound scans of their gut before and after eating breakfast. Ovchinin then packed gear for return on a future Soyuz landing as Skvortsov checked Russian video and photography gear.

Satellite Software Contest on Station as Crew Tests Organ Printing

The International Space Station is the setting today for a student competition to control tiny, free-floating satellites aboard the orbiting lab. Meanwhile, the Expedition 60 crewmembers conducted a variety of research operations and continued configuring a pair of spacesuits.

Middle school students are competing to design algorithms that autonomously control basketball-sized SPHERES satellites aboard the station. The student-written software tests rendezvous and docking maneuvers that simulate scenarios such as retrieving an inoperable satellite. Flight Engineers Andrew Morgan and Alexander Skvortsov were on hand monitoring the SPHERES contest inside the Kibo laboratory module.

NASA astronaut Christina Koch is helping scientists learn how to print and grow human organs in space. She printed tissue samples using the BioFabrication Facility in the Columbus lab module. The samples are housed for several weeks inside a specialized incubator to promote cellular growth. Earth’s gravity inhibits 3-D bioprinters and incubators from recreating and growing complex organic structures.

Flight Engineers Nick Hague and Luca Parmitano continued working on U.S. spacesuits and spacewalking tools during the afternoon. Hague started the day configuring a fluorescence microscope that can observe cellular changes in microgravity. Parmitano serviced Europe’s Fluid Science Laboratory to continue researching the physics of fluids in microgravity.

Commander Alexey Ovchinin worked in the Russian segment of the space lab today readying obsolete gear for return to Earth aboard a Soyuz spacecraft. The veteran cosmonaut spent the rest of the afternoon servicing life support gear and inspecting biology research hardware.

Crew Gears Up for Spacewalk, Scans Eyes and Practices Medical Emergency

The Expedition 60 crew is gearing up for an upcoming spacewalk to prepare the International Space Station for more commercial crew missions. Biomedical science also took up a portion of the astronauts’ day as they help researchers understand what happens to the human body in microgravity.

NASA astronauts Nick Hague and Andrew Morgan are reviewing their tasks planned for Aug. 21 when they conduct the fifth spacewalk of the year at the orbiting lab. The duo will take about six-and-a-half hours to install the International Docking Adapter-3 (IDA-3) on top of the Harmony module. The IDA-3, delivered inside the Dragon cargo craft’s trunk, will be the second port at the station designed to receive the new Boeing and SpaceX crew ships.

Flight Engineers Christina Koch and Luca Parmitano are helping the spacewalkers get ready for the upcoming excursion. They are configuring spacesuit components today and will continue assisting the pair before, during and after the next spacewalk.

Morgan first joined Koch and Parmitano during the morning for ultrasound eye exams. Koch took charge of the eye scans in the Columbus lab module with real-time inputs from doctors on the ground. She observed her crewmates’ retina, cornea, lens and optic nerve to maintain eye health in space.

Koch and Parmitano later split up feeding the station’s mice and cleaning their habitats in the Destiny laboratory module. Observing the rodents, which are genetically similar to humans, in the weightless environment of microgravity gives scientists critical therapeutic insights that can benefit Earthlings and astronauts.

The most recent trio to arrive at the station gathered at the end of the day to train for a medical emergency. Morgan, Parmitano and cosmonaut Alexander Skvortsov practiced cardiopulmonary resuscitation (CPR), checked out medical gear and reviewed emergency communications.

Spacewalk Targeted for Aug. 21, Crew Researching Organ Printing and Alzheimer’s

International Space Station managers have targeted Aug. 21 for the next spacewalk at the orbiting lab. NASA astronauts Nick Hague and Andrew Morgan will work outside in the vacuum of space to install a new commercial crew docking port, the International Docking Adapter-3 (IDA-3).

Robotics controllers will remove the IDA-3 from the trunk of the SpaceX Dragon two days before the spacewalk and ready it for the six-and-a-half hour installation job. Hague and Morgan will install and configure the new docking adapter to the top of the Harmony module. Once connected, the IDA-3 will be ready to receive new Boeing and SpaceX crew ships.

Meanwhile, the six Expedition 60 crewmembers kept the station humming on Wednesday performing new microgravity research and maintaining life support systems. Biology and physics research in space reveals new phenomena potentially benefiting humans both on Earth and in space.

NASA astronaut Christina Koch serviced the new BioFabrication Facility today to help scientists take advantage of the properties of weightlessness to successfully print and grow human organs. Earth’s gravity can inhibit 3-D bioprinters and incubators from recreating and growing complex organic structures.

Luca Parmitano of the European Space Agency (ESA) researched possible causes for neurodegenerative conditions such as Alzheimer’s disease. The crew is examining protein samples for amyloid formation that differ from samples observed on Earth. Results may inform preventative therapies for Earthlings and astronauts on long-term missions.

Students on Earth are learning how to maneuver tiny satellites inside the station today. Morgan set up a pair of basketball-sized SPHERES satellites controlled by student-written algorithms. The middle school kids are practicing rendezvous and docking techniques in the Kibo laboratory module.

Hague is setting up material samples for robotic installation outside Kibo. The Japanese robotic arm, smaller cousin to the Canadarm2, will remove the scientific samples from the module’s airlock and install them on an external platform. Researchers observe the exposed materials to understand the effects of microgravity and space radiation.

U.S. Cygnus Space Freighter Departs Station

The Cygnus spacecraft successfully departed the International Space Station three months after arriving at the space station to deliver 7,600 of supplies and scientific experiments to the orbiting laboratory.

The Cygnus spacecraft will now remain in orbit until mid-December and coincide with a second Cygnus spacecraft scheduled for launch to the space station in October. This will be the first extended duration flight to demonstrate spacecraft’s capability to fly two Cygnus vehicles simultaneously and support hosted payloads for longer periods of time.
