Northrup Grumman’s Cygnus cargo spacecraft departed the International Space Station’s at 9:36 a.m. EST after Expedition 61 Flight Engineers Andrew Morgan and Jessica Meir of NASA commanded its release from the Canadarm2 robotic arm. At the time of release, the station was flying about 250 miles over the South Pacific just off the West Coast of Chile.
For this mission, Cygnus demonstrated a new release position for departure operations and incorporated the first ground-controlled release. The new orientation allowed for easier drift away from the station’s Canadarm2 robotic arm.
Within 24 hours, Cygnus will begin its secondary mission deploying a series of payloads. The departing spacecraft will move a safe distance away from the space station before deploying a series of CubeSats: HuskySat-1 (University of Washington), SwampSat II (University of Florida), EdgeCube (Sonoma State University), and CIRis (Utah State University).
Northrop Grumman flight controllers in Dulles, Virginia, will initiate its deorbit and execute a safe, destructive reentry into Earth’s atmosphere at the end of February.
The next Cygnus is set to launch to station on Feb. 9 from NASA’s Wallops Flight Facility in Virginia carrying another batch of research.
The spacecraft arrived on station November 2 delivering cargo under NASA’s Commercial Resupply Services contract.
A Northrop Grumman cargo ship, dubbed the SS Alan Bean, is set to depart the International Space Station Friday, Jan. 31. Live coverage of the spacecraft’s release will begin on NASA Television and the agency’s website at 9:15 a.m. with release scheduled for 9:35 a.m.
With Expedition 61 Flight Engineers Andrew Morgan and Jessica Meir of NASA providing backup support, ground controllers will send commands to the Canadarm2 robotic arm to release the unpiloted cargo spacecraft after ground controllers remotely unbolt the craft from the Earth-facing port of the Unity module and maneuver it into release position.
NG-12 Cygnus delivered 8,200 pounds of science and research investigations, supplies, and hardware to the International Space Station on Saturday, Nov. 2. The investigations range from research into human control of robotics in space to reprocessing fibers for 3D printing.
Cardiology, combustion and CubeSats filled Thursday’s research schedule as three Expedition 61 crewmates are one week away from returning to Earth. The Cygnus space freighter is also poised to depart the International Space Station on Friday and complete one more mission.
NASA astronaut Christina Koch is nearing the end of her 328-day mission aboard the orbiting lab. She will land in Kazakhstan Feb. 6 aboard the Soyuz MS-13 crew ship with Alexander Skvortsov of Roscosmos and Luca Parmitano of ESA (European Space Agency). Koch blasted off to join the station crew on March 14 while Skvortsov and Parmitano began their mission on July 20.
When Koch lands, her mission-stay will be the second longest single spaceflight by a U.S. astronaut behind former astronaut Scott Kelly. He lived aboard the station for 340 continuous days.
NASA Flight Engineer Andrew Morgan juggled a pair of experiments this morning. He ran the Hourglass study observing how simulated planetary materials behave during different gravity conditions. Next, he cleaned a furnace that exposes materials to high temperatures and levitates them to research their thermophysical properties.
Parmitano started his day on cardiology research before switching to fire safety studies. The station commander first scanned portions of his body with an ultrasound device. The biomedical study is helping doctors understand what happens to the heart and blood vessels in space. He then moved on and burned a variety of fabric and acrylic samples. Scientists are using the data to model how flames spread in space to improve fire safety procedures and products in space and on Earth.
The Cygnus space freighter is packed, closed and ready for one more mission after its robotic release from the Canadarm2 Friday at 9:35 a.m. EST. It will deploy eight CubeSats for communications and atmospheric research several hours after departing the orbiting lab. Flight Engineer Jessica Meir installed the CubeSats, packed inside the SlingShot small satellite deployer, on Cygnus’ hatch Thursday afternoon.
The Expedition 61 crew’s schedule was packed today as they researched space biology and packed a pair of spaceships for departure. Wednesday morning also saw the deployment of an experimental satellite outside the International Space Station.
Blood draws and eye checks are part of the crew’s regimen of biomedical activities to help doctors keep astronauts healthy during long-term space missions. Commander Luca Parmitano of ESA (European Space Agency) collected his blood samples this morning before spinning them in a centrifuge and stowing them in a science freezer for later analysis. NASA Flight Engineer Jessica Meir had her eyes scanned in the afternoon by fellow NASA astronaut Andrew Morgan using optical coherence tomography gear.
Meir and Morgan started the day finishing up packing the Cygnus space freighter with trash and discarded gear before it leaves at the end of the week. Cygnus will be detached from the Unity module with the Canadarm2 robotic arm and released into Earth orbit on Friday at 9:35 a.m. EST. NASA TV will cover the release and departure live as mission controllers on the ground remotely command all the robotics work.
Cygnus has another mission to deploy eight CubeSats for communications and atmospheric research once it reaches a safe distance away from the orbiting lab. The space station also saw the deployment early this morning of a Department of Defense CubeSat that is testing space weather and satellite sensor technology. That satellite was deployed outside of the Kibo laboratory module using the specialized Cyclops deployer.
Christina Koch of NASA is returning to Earth next week after 328 days in space on her first mission. She will land in Kazakhstan with Parmitano and cosmonaut Alexander Skvortsov. The trio will board the Soyuz MS-13 crew ship, undock from the Poisk module and parachute to a landing Friday, Feb. 6, at 4:13 a.m. (3:13 p.m. Kazakh time).
Koch will be second only to former astronaut Scott Kelly who lived in space 340 days for the single longest spaceflight by a U.S. astronaut.
The Cold Atom Lab (CAL) enables research into the quantum effects of gases chilled to nearly absolute zero, which is colder than the average temperature of the universe. NASA Flight Engineers Jessica Meir and Christina Koch opened up the CAL today to swap and clean hardware inside the quantum research device.
Mission controllers will then remotely command the Japanese robotic arm to grapple and deploy Cyclops outside Kibo overnight. The tiny satellite, packed with a variety of space weather and star tracker experiments, will be deployed into Earth orbit Wednesday morning.
Meir then installed a different small satellite deployer, this one called SlingShot, on the Cygnus space freighter attached to the Unity module. The SlingShot, attached to Cygnus’ hatch, will release a variety of small satellites after the U.S. cargo craft departs the space station on Friday at 9:35 a.m. EST. The suite of eight CubeSats will study different optical and communication technologies as well as atmospheric and natural phenomena.
Koch is getting ready to come home on Feb. 6 with fellow crewmates Luca Parmitano of ESA (European Space Agency) and Alexander Skvortsov of Roscosmos. The trio performed leak checks today on the Sokol launch and entry suits they will wear aboard the Soyuz MS-13 crew ship when they parachute to a landing in Kazakhstan.
Upon landing, Koch will have lived in space continuously for 328 days on her first mission. She will be second only to former astronaut Scott Kelly who lived in space 340 days for the single longest spaceflight by a U.S. astronaut.
Engineers on the ground have begun powering up the Alpha Magnetic Spectrometer’s (AMS) thermal system following a successful repair spacewalk over the weekend. The Expedition 61 astronauts are now preparing a U.S. cargo craft for its departure at the end of the week.
It took four spacewalks over three months to restore and upgrade thermal operations on the AMS. Astronauts Andrew Morgan and Luca Parmitano wrapped up the complex repair job on Saturday for the 8-year-old cosmic particle detector. Soon after the spacewalk, payload controllers reported stable cooling operations on the AMS, and are continuing to monitor its thermal conditions. The AMS will soon resume its search for evidence of dark matter and antimatter once the system checkouts are complete.
The crew are now turning their attention to packing Northrop Grumman’s Cygnus resupply ship with trash and discarded hardware. Robotics controllers in Mission Control will command the Canadarm2 robotic arm to release Cygnus on Friday at 9:35 a.m. EST after 88 days attached to the Unity module. The private cargo carrier will reenter Earth’s atmosphere over the South Pacific for a fiery, but safe disposal.
NASA Flight Engineers Jessica Meir and Christina Koch started Monday on housecleaning tasks. They were joined by Morgan and Parmitano cleaning fans and filters and disinfecting surfaces containing microbes and condensation.
Cosmonaut Alexander Skvortsov is getting the Soyuz MS-13 crew ship ready for its return to Earth on Feb. 6. He will parachute to a landing in Kazakhstan with Koch and Parmitano just three and half hours after undocking from the Poisk module. Koch will have lived in space continuously for 328 days on her first mission, second only to former astronaut Scott Kelly who lived in space 340 days for the single longest spaceflight by a U.S. astronaut.
Expedition 61 crew members Andrew Morgan of NASA and Luca Parmitano of ESA (European Space Agency) concluded their spacewalk at 1:20 p.m. EST. During the 6 hour, 16 minute spacewalk, the two astronauts successfully completed leak checks for the cooling system on the Alpha Magnetic Spectrometer (AMS) and opened a valve to being pressurizing the system. Preliminary testing shows AMS is responding as expected.
Ground teams will work over the next several days to fill the new AMS thermal control system with carbon dioxide, allow the system to stabilize, and power on the pumps to verify and optimize their performance. The tracker, one of several detectors on AMS, should be collecting science data again before the end of next week. The upgraded cooling system is expected to support AMS through the lifetime of the space station.
AMS is a joint effort between NASA and the Department of Energy’s Office of Science and is led by Principal Investigator Samuel Ting, a Nobel laureate from the Massachusetts Institute of Technology. The AMS team includes some 600 physicists from 56 institutions in 16 countries from Europe, North America and Asia. AMS has been capturing high-energy cosmic rays to help researchers answer fundamental questions about the nature of antimatter, the unseen “dark matter” that makes up most of the mass in the universe, and the even-more-mysterious dark energy that is speeding up the expansion of the cosmos.
The astronauts also completed an additional task to remove degraded lens filters on two high-definition video cameras.
This was the fourth spacewalk by Morgan and Parmitano to repair the spectrometer and the 227th in support of station assembly, maintenance and upgrades. For Morgan, it was the seventh spacewalk of his career, for a total of 45 hours and 48 minutes, and the sixth for Parmitano, with a total of 33 hours and 9 minutes, who will return to Earth Feb. 6 in a Russian Soyuz spacecraft to complete a six-and-a-half month mission on the outpost. Spacewalkers have now spent a total of 59 days 12 hours and 26 minutes working outside the station. This was also the ninth spacewalk for the Expedition 61 crew, more than in any other increment in the history of the station.
Two astronauts switched their spacesuits to battery power this morning at 7:04 a.m., EST aboard the International Space Station to begin a spacewalk planned to last about six-and-a-half hours. NASA Flight Engineer Andrew Morgan and Expedition 61 Commander Luca Parmitano of ESA (European Space Agency) will venture outside the International Space Station to complete repairs on a cooling system for the Alpha Magnetic Spectrometer (AMS), a cosmic ray detector. The duo will conduct leak checks for the spectrometer’s refurbished cooling lines and complete the work to resume operations of the cosmic ray detector.
Morgan is designated extravehicular crewmember 1 (EV 1), wearing the suit with red stripes, and with the helmet camera labeled #20. Parmitano is designated extravehicular crew member 2 (EV 2), wearing the suit with no stripes, and with helmet camera #18.
During the first three spacewalks in the complex series to repair the AMS, the astronauts carefully prepared the AMS and positioned materials, installed the upgraded cooling system, completed the power and data cable connection for the system. The intricate connection work required making a clean cut for eight existing stainless steel tube cooling lines connected to the AMS then connecting it to the new system through a process of metalworking known as swaging. Following the third spacewalk, the flight control team on Earth initiated power-up and confirmed the new system was receiving power and data.
In addition to revitalizing an important piece of scientific equipment, the process of creating the tools and procedures for these spacewalks is preparing teams for the types of spacewalks that may be required on Moon and Mars missions.
Expedition 61 NASA Flight Engineer Andrew Morgan and Commander Luca Parmitano of ESA (European Space Agency) will begin a spacewalk outside of the International Space Station at about 6:50 a.m. EST Saturday, Jan. 25. NASA Television coverage of the spacewalk will begin at 5:30 a.m.
This will be the ninth spacewalk for the Expedition 61 crew, more than in any other increment in the history of the station. The two astronauts will venture outside the International Space Station for the last planned spacewalk in a series to repair the Alpha Magnetic Spectrometer (AMS), a cosmic ray detector.
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 included cutting and splicing of eight cooling tubes to connect to a new cooling system, and connecting a myriad of power and data cables.
Morgan and Parmitano were joined by NASA Flight Engineers Jessica Meir and Christina Koch for a final procedures review with mission controllers on the ground. Meir and Koch will operate the Canadarm2 robotic arm carefully making fine-tuned maneuvers to assist the spacewalkers at the AMS worksite.
Meir and Koch began their workday by performing scans of their neck, arm, leg and feet muscles with an ultrasound device. The scans are downlinked to doctors studying how weightlessness affects the biochemical properties of muscles. The pair also collected their blood samples and stowed them in a science freezer for the human research study. Insights my impact health strategies on future long-term space missions.
Cosmonauts Alexander Skvortsov and Oleg Skripochka spent Friday morning on a Russian digestion study today scanning their stomachs with another ultrasound device before and after breakfast. They split up in the afternoon working on a variety of station hardware maintenance and crew departure activities.
