NASA TV Broadcasts Particle Detector Spacewalk Repairs on Friday

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 Friday, Nov. 15. NASA Television coverage of the spacewalk will begin at 5:30 a.m.

Watch the spacewalk on NASA TV and on the agency’s website.

The two astronauts will venture outside the International Space Station for the first in a series of complex spacewalks to replace a cooling system on the Alpha Magnetic Spectrometer (AMS), a cosmic ray detector. The upgraded cooling system will support AMS through the lifetime of the space station.

Parmitano and Morgan have spent dozens of hours training specifically for the AMS repair spacewalks. NASA astronauts Christina Koch and Jessica Meir will help Parmitano and Morgan suit up for the spacewalks and will maneuver the Canadarm2 robotic arm to help position the spacewalkers around the AMS repair worksite.

These spacewalks are considered the most complex of their kind since the Hubble Space Telescope servicing missions. The AMS originally was designed for a three-year mission and, unlike Hubble, was not designed to be serviced once in space. More than 20 unique tools were designed for the intricate repair work, which will include the cutting and splicing of eight cooling tubes to be connected to the new system, and reconnection of a myriad of power and data cables. In addition to the overall complexity, astronauts have never before cut and reconnected fluid lines, like those that are part of the cooling system, during a spacewalk.

Final Spacewalk Preps During Biology, Physics Studies

The Expedition 61 crew is about to kick off a series of complex spacewalks on Friday to repair the International Space Station’s cosmic particle detector. They will have one more spacewalk review today while continuing advanced biology research.

Spacewalkers Luca Parmitano and Andrew Morgan readied the Quest airlock, their U.S. spacesuits and tools for Friday’s excursion set to begin at 7:05 a.m. EST. The duo then joined Flight Engineers Jessica Meir and Christina Koch for a final procedures review. All four astronauts called down to Mission Control to discuss their readiness with spacewalk experts on the ground. Live NASA TV coverage begins at 5:30 a.m.

Meir and Koch spent the rest of Thursday on space research and lab upkeep. Meir conducted a test run of a 3-D bioprinter before the device will manufacture complex human organ tissue shapes. Koch measured airflow in the station then serviced microbe samples to extract and sequence their DNA.

Cosmonauts Alexander Skvortsov and Oleg Skripochka focused on their complement of science and maintenance in the station’s Russian segment. Skvortsov updated cargo inventory and explored plasma physics for insights into advanced spacecraft designs. Skripochka collected radiation readings and studied how a crew adapts to piloting in space.

Space Gardening Aboard Station Ahead of Spacewalks

The Expedition 61 crewmembers started taking turns “weighing in” Wednesday before a slew of space gardening and life science activities. The orbital residents are also nearing the start of a series of spacewalks to repair the International Space Station’s cosmic particle detector.

Isaac Newton’s Second Law of Motion allows for the calculation of mass in space using a variant of the equation — force equals mass times acceleration. Each crewmate attached themselves to a device this morning that applies a known force to the subject. The resulting acceleration provides a value used to calculate an astronaut’s mass.

It is harvest time once again aboard the orbiting lab. NASA astronauts Jessica Meir and Christina Koch cut leaves from Mizuna mustard greens grown inside ESA’s (European Space Agency) Columbus lab module. Half of the space crop is destined for crew tasting while the other half was stowed in science freezers for analysis on Earth.

NASA Flight Engineer Andrew Morgan is getting ready for Friday’s spacewalk with ESA Commander Luca Parmitano. Morgan reviewed robotics activities planned for Friday’s excursion and checked spacewalking gear. The duo will set their U.S. spacesuits to battery power at 7:05 a.m. EST inside the Quest airlock signifying the start of their spacewalk. NASA TV begins its live coverage at 5:30 a.m.

Parmitano focused on science today attaching electrodes to himself after his “weigh-in” to measure any changes to his body fat. Afterward, he collected noise level measurements in Russia’s Zarya module. He then set up samples in the U.S. Destiny lab module to explore how fluids behave in microgravity to improve medical conditions on Earth.

Cosmonaut Oleg Skripochka handed over radiation detectors to Meir for deployment in the station’s U.S. segment. He later joined cosmonaut Alexander Skvortsov and recorded video to share historical space accomplishments with Russian audiences.

Crew Preps for Friday Spacewalk During Continuous Science

The International Space Station’s cosmic particle detector, in operation since 2011, will get its first repair job during a series of spacewalks set to start this Friday. The Expedition 61 crew is gearing up for the spacewalk while ensuring ongoing advanced space research.

Commander Luca Parmitano of ESA (European Space Agency) will lead at least four excursions into the vacuum of space to upgrade the Alpha Magnetic Spectrometer (AMS). NASA Flight Engineer Andrew Morgan will assist the commander as they cut and reconnect fluid lines on the AMS’ thermal control system. The AMS captures cosmic particles and measures their electrical charge in its search for antimatter and dark matter.

NASA TV begins its live spacewalk coverage Friday at 5:30 a.m. EST. Parmitano and Morgan will set their U.S. spacesuits to battery power at 7:05 a.m. signifying the start of their spacewalk.

NASA astronauts Jessica Meir and Christina Koch will support the duo on Friday. Meir will be in charge of the Canadarm2 robotic arm while Koch manages the U.S. spacesuits. All four astronauts gathered today and reviewed robotics procedures for the spacewalk repairs.

Life science and space physics also took up a portion of the crew’s schedule today. Koch checked out hardware on a 3-D bioprinter and watered plants as Meir fed lab mice. Morgan and Parmitano serviced biology and fluids research gear.

In the Russian segment of the station, a pair of cosmonauts packed a resupply ship for its Nov. 29 departure while working science and life support maintenance. Flight Engineer Alexander Skvortsov researched plasma crystals for an experiment that may inform future spacecraft designs. Oleg Skripochka checked the Zarya module’s power supply system before plumbing work and computer maintenance.

Crew Focuses on Cosmic Repair Spacewalks, Practices Medical Emergency

The Expedition 61 crew is focusing on a complex series of spacewalks set to start soon to repair a cosmic particle detector. The orbital residents also conducted an emergency drill aboard the International Space Station today.

Astronauts Luca Parmitano and Andrew Morgan are familiarizing themselves with new spacewalking gear delivered aboard the Cygnus space freighter. The duo will use the new tools and hardware on a series of spacewalks to repair the Alpha Magnetic Spectrometer’s (AMS) thermal control system.

The spacewalks will highlight advanced repair techniques, including cutting and reconnecting fluid lines, never performed during a spacewalk. Parmitano and Morgan are set to venture outside the station on Friday Nov. 15 to begin the first of at least four spacewalks to upgrade the AMS, a device that searches for dark matter and antimatter.

NASA astronauts Jessica Meir and Christina Koch joined the upcoming spacewalkers today and reviewed tools and procedures for the excursions. The quartet then called Mission Control for a conference with experts on the ground about their spacewalking duties.

At the end of the workday, all six crew members, including cosmonauts Alexander Skvortsov and Oleg Skripochka, practiced responding to an emergency simulation. The crew reviewed safety and medical gear, translated evacuation paths, practiced chest compressions (CPR) and coordinated communications.

The space station raised its orbit during the crew’s sleep period Thursday night when Russia’s Progress 73 resupply ship fired its thrusters for six minutes and 45 seconds. Now orbiting a mile higher at its perigee, the orbital complex is at the correct altitude for Russia’s next resupply ship, Progress 74, to dock on Dec. 3 after it launches Dec. 1.
