Human research and space biology dominated the research schedule aboard the International Space Station today. The Expedition 62 crew investigated how microgravity impacts heart and bone cells and head and eye pressure.

All three crewmembers tested a unique suit Tuesday that draws body fluids, such as blood and water, towards the feet. This counteracts space-caused fluid shifts toward the head that create pressure on an astronaut’s eyes and cranium. One visible symptom, called “puffy face,” is a redder and rounder face due to those shifts. However, astronauts have reported vision problems after living in space for months at a time.

Flight Engineer Andrew Morgan put on the suit with help from Commander Oleg Skripochka in the station’s Zvezda service module. NASA astronaut Jessica Meir then scanned Morgan’s eyes, head and chest with an ultrasound device to measure blood flow through his veins and arteries. Doctors on Earth monitored the activities to learn more about the effectiveness of the negative pressure body suit.

Morgan then moved on to cardiac research, learning how to create and culture heart cells on the space station. Results could provide advanced therapies to prevent heart conditions on Earth and in space. Meir continued more bone research servicing bone samples to help scientists better understand Earth ailments such as osteoporosis.

The commander stayed in the station’s Russian segment inventorying cargo from a Russian resupply ship. Skripochka, a veteran of three station missions, made space in the Progress 74 cargo craft temporarily stowing goods and rearranging hardware to reduce clutter aboard the orbiting lab.

The Expedition 62 crew focused on a variety of human research and space biology studies aboard the International Space Station today. Back on Earth, three new crewmembers are in training in Russia before their mission begins in April.

Microgravity shifts the flow of body fluids, such as blood and water, which accumulate in an astronaut’s head creating pressure in the cranium and on the eyes. Doctors are continuously studying this phenomenon to counteract the effects and keep long-term space crews healthy.

In preparation for upcoming operations with the ongoing Fluid Shifts study, NASA astronaut Andrew Morgan collected medical hardware, such as an ultrasound device, sensors and cables. He transferred the research gear to the Russian segment, where they will be used to test a specialized body suit that draws fluids toward the lower body expanding veins and tissues.

Morgan then moved on to a Japanese study that looks at how weightlessness affects genetic expression in mice.  Results may inform future therapies that keep crews safe in space and prevent muscle atrophy conditions on Earth.

NASA Flight Engineer Jessica Meir relaxed on Monday aboard the orbiting lab after working Saturday afternoon on cardiac research. She serviced heart cells being manipulated and analyzed with magnet-sensors and stowed them in a science freezer. The space samples are being compared to cell cultures on the ground possibly benefitting human cardiac function on Earth and in space.

Commander Oleg Skripochka began his morning on a long-running Russian study exploring how cosmonauts will pilot spacecraft and even robotic rovers on future planetary missions. During the afternoon, he turned his attention to life support maintenance.

Over in Russia, three Expedition 63 crewmembers are getting ready for their launch to the space station on April 9. NASA astronaut Chris Cassidy and Roscosmos cosmonauts Anatoly Ivanishin and Ivan Vagner wrapped up two days of Soyuz qualification exams last week. They will have a news conference this Friday before heading out to the Baikonur Cosmodrome in Kazakhstan on Tuesday, March 24. Once there, the crew will be in final preparations ahead of their 195-day mission in space.

New cardiac research is beginning today on the International Space Station. NASA astronaut Jessica Meir is installing gear that will support heart cells being produced inside the U.S. Destiny laboratory module. Those cells will be compared to cultures on Earth to promote regenerative cell therapies.

She also continued bone sample operations for the ongoing OsteoOmics-02 study. The investigation takes place in the Japanese Kibo laboratory module and may reveal innovative bone treatments for humans living on Earth and in space.

Meir also joined fellow NASA Flight Engineer Andrew Morgan for maintenance work on a U.S. spacesuit. The duo recharged and swapped out components inside the suit ahead of spacewalks planned for this year.

Morgan also spent Friday working on orbital plumbing and space biology research. He first serviced hardware in the station’s bathroom located in the Tranquility module during the morning. Afterward, Morgan photographed bacteria samples for an experiment seeking improved therapies for antibiotic-resistant infections.

Commander Oleg Skripochka spent the majority of his day focusing on life support and computer activities over in the Russian segment of the space station. In the afternoon, the veteran cosmonaut set up and activated gear that observes the atmosphere at nighttime in near-ultraviolet wavelengths.

The Expedition 62 crew took a break today from its weeks-long space biology research aboard the International Space Station. Instead, the orbital residents focused on setting up an external science payload and maintaining life support systems.

Research takes place not only inside the space station, but also outside as scientists study how extreme temperatures and space radiation affect a variety of materials. NASA Flight Engineer Andrew Morgan configured hardware today containing a materials science experiment for installation outside the orbital lab. He placed the gear inside the Kibo laboratory module’s airlock where it was depressurized. The Canadarm2 robotic arm will retrieve the experiment and externally install it on the station.

NASA astronaut Jessica Meir started her day collecting samples of the station’s water for microbial analysis. In the afternoon, she serviced an experiment module that can generate artificial gravity environments before working on orbital plumbing at the end of her shift.

Veteran cosmonaut and station Commander Oleg Skripochka continued more communication tests today checking two-way audio and video satellite links. He also wrapped up a study that observed Earth’s upper atmosphere in visible and near-infrared wavelengths. At the end of the day, Skripochka shared his inputs for the long-running experiment researching the interactions between crews and mission controllers.

The new Expedition 63 crew is in Russia getting ready for its launch on April 9 aboard the Soyuz MS-16 crew ship. NASA astronaut Chris Cassidy with Roscosmos cosmonauts Anatoly Ivanishin and Ivan Vagner are wrapping up two days of final qualification exams. The trio will soon head to the Baikonur Cosmodrome in Kazakhstan for final preparations before beginning their 195-day mission aboard the orbiting lab.

Bone cells and now heart cells are on the space research agenda for the Expedition 62 crew. The International Space Station continues gearing up for more space investigations recently delivered aboard the SpaceX Dragon resupply ship.

NASA Flight Engineer Jessica Meir turned her attention today to a new experiment exploring cardiac activity in microgravity. She tended to heart cells swapping media that nourishes the samples being observed and manipulated with magnetic sensors. The results could inform measures to keep astronauts healthy on long-term missions and possibly treat heart conditions on Earth.

Bone health is also important for humans living and working on and off the Earth. Over in the Japanese Kibo laboratory module, NASA astronaut Andrew Morgan worked in the Life Science Glovebox servicing bone cell samples for an experiment that began in February. That research is comparing samples nurtured in weightlessness to a set of samples that are magnetically levitated in a lab on Earth. Insights could prove valuable when treating bone ailments such as osteoporosis.

The pair also split their time on several other investigations ranging from radiation detection to protein crystals. Radiation detectors were retrieved from Dragon and installed throughout the station to characterize the orbital lab’s radiation dosage and distribution. The crew also looked at protein crystals that grow better in space than on Earth, for a pair of studies, PCG-10 and JAXA Moderate Temp PCG, supporting the development of more effective medications.

Commander Oleg Skripochka focused on Russian communications gear throughout the day testing two-way audio and video satellite links. He also spent some time exploring advanced photography techniques to locate Earth targets.
