Watch NASA TV Monday as Spacewalkers Continue Cosmic Repair Work
Expedition 61 Commander Luca Parmitano of ESA (European Space Agency) and NASA Flight Engineer Andrew Morgan will begin a spacewalk outside of the International Space Station at about 7 a.m. EST. NASA Television coverage of the spacewalk will begin at 5:30 a.m.
The two astronauts will venture outside the International Space Station for the third in a series of complex spacewalks to replace a cooling system on the Alpha Magnetic Spectrometer (AMS), a cosmic ray detector. The primary tasks for Monday’s spacewalk will be the installation of a new cooling pump for the AMS and the cutting and splicing of cooling lines for the new unit.
During the first spacewalk in the series to repair the AMS on Nov. 15, the astronauts positioned materials and conducted work in preparation for the repairs. In the second spacewalk Nov. 22, the crew successfully cut and labeled the stainless steel tubes that attach the current cooling system to the AMS.
Belated Thanksgiving Meal Ahead of Spacewalk and New Cargo Ships
The six-member Expedition 61 crew is relaxing today and enjoying a belated Thanksgiving meal after an intense week of biology research and spacewalk preparations. A Russian resupply ship also departed the International Space Station this morning as two more space freighters are poised to replenish the orbiting lab. The ISS Progress 73 cargo ship, loaded with trash, undocked from the Pirs Docking Compartment and was deorbited, burning up over the Pacific Ocean.
The four astronauts and two cosmonauts on the orbiting lab were off-duty today sharing a Thanksgiving meal together after working all day during the U.S. holiday. Most of the fixings that dress a turkey on a dining table on Earth were available aboard the station’s galley including cornbread, green beans, mashed potatoes and gravy.
Morgan and Parmitano now turn their attention to Monday’s spacewalk to continue the complex repair job on a cosmic particle detector on the station’s truss. They will be employing complex and innovative repair techniques never performed in space to replace a faulty cooling pump on the Alpha Magnetic Spectrometer. The spacewalkers will set their U.S. spacesuits to battery power at 6:50 a.m. EST on Monday signifying the start of their venture. NASA TV begins its live broadcast at 5:30 a.m.
Cosmonauts Alexander Skvortsov and Oleg Skripochka monitored the Progress 73 resupply ship as it undocked at 4:25 a.m. EST Friday completing its four-month mission at the station. It reentered the Earth’s atmosphere a few hours later and burned up safely over the south Pacific.
Thanksgiving Bringing Harvest, Spacewalk Preps and Disease Research
The Expedition 61 crew is heading into Thanksgiving with more blood and cell research to improve human health. There will also be a harvest on the U.S. holiday as spacewalk preparations continue.
Rodents living aboard the International Space Station are being observed this week with their blood and cell samples being collected and stowed in science freezers. Doctors are exploring how microgravity affects the cellular level systems of mice to gain insights into afflictions such as cancer and diabetes. Results may inform the development of advanced therapies for Earth-bound and space-caused ailments.
Morgan and Parmitano will set their U.S. spacesuits to battery power at 6:50 a.m. EST on Monday signifying the start of their spacewalk. They will use new tools and techniques never performed in space for the intricate task of replacing the Alpha Magnetic Spectrometer’s thermal control system. NASA TV begins its live broadcast at 5:30 a.m.
The crew will be busy on Thanksgiving with more disease therapy studies and a space crop harvest as well. Koch and Meir will be harvesting Mizuna mustard greens and sharing the leaves with the crew for a taste test on Thursday. The rest of the crop will be packed in a lab freezer for later analysis.
Astronauts Research Disease Therapies Ahead of Complex Repair Spacewalk
Two Expedition 61 astronauts are getting up to speed with the fine repair techniques they will use next week during the 11th spacewalk of 2019. The International Space Station is also hosting intense biology work this week to improve the health of humans in space and on Earth.
The orbiting lab’s cosmic particle detector, the Alpha Magnetic Spectrometer (AMS), is getting a new thermal control system that requires innovative spacewalking repair techniques. Astronauts Andrew Morgan and Luca Parmitano are studying the careful, deliberate procedures with new tools specifically designed for the job. The AMS, which has exceeded its three-year operational lifespan by five-and-a-half years, was never designed to be repaired in space.
Morgan and Parmitano will continue the AMS repair job during their third spacewalk together beginning Monday at 6:50 a.m. EST. This will be the third of four planned spacewalks to ensure the astrophysics device continues searching for evidence of dark matter and antimatter for years to come. NASA TV will start its live broadcast at 5:30 a.m.
The Life Sciences Glovebox (LSG) in the Japanese Kibo lab module is seeing a lot of biology research work this week. NASA astronauts Jessica Meir and Christina Koch are looking at blood and cell samples in the LSG to understand the stresses microgravity imposes on organisms. Doctors are looking for advanced therapeutic insights into Earth-bound diseases such as cancer and diabetes as well as space-caused ailments. Morgan and Parmitano are also on life science duty this week assisting the duo in between spacewalk preparations.
In the Russian segment of the station, Roscosmos Flight Engineer Oleg Skripochka attached sensors to his legs to observe how his veins are adapting to long-term spaceflight. Cosmonaut Alexander Skvortsov worked on computer hardware and life support gear.
Disease Therapy Research Ahead of Cargo Traffic and Spacewalks
Thanksgiving week starts with the Expedition 61 crew exploring the stresses microgravity imposes on organisms at the cellular level. The International Space Station is also ramping up for cargo traffic and another spacewalk in December.
The astronauts in the U.S. segment of the orbiting lab focused their attention today on identifying the cellular changes caused by weightlessness. Observations may provide doctors with advanced therapeutic insights into diseases afflicting humans on Earth and ailments that affect astronauts in space.
Two more spacewalks are scheduled to service an astrophysics device, the Alpha Magnetic Spectrometer (AMS), searching for clues to the origin of the universe. Astronauts Andrew Morgan and Luca Parmitano will continue the complex work on Monday, Dec. 2 at 6:50 a.m. EST to replace the AMS thermal control system.
Russia’s Progress 73 cargo craft will compete its 121-day mission attached to the Pirs docking compartment this Friday and undock for a fiery disposal above the south Pacific. It will be replaced when the Progress 74 resupply ship launches Dec. 6 and docks to Pirs on Dec. 8.
