The Cygnus space freighter is on orbit today and refining its approach to the International Space Station following its launch from Virginia Thursday afternoon. Meanwhile, the Expedition 59 crew is juggling a variety of science and maintenance activities today before Friday morning’s space shipment arrives.
Astronaut Anne McClain, with Flight Engineer David Saint-Jacques as her back up, will capture Cygnus with the Canadarm2 robotic arm around 5:30 a.m. Friday. Ground controllers will take over afterward and remotely install Cygnus to the Unity module where it will stay until the end of July.
Cygnus is packed with about 7,600 pounds of science, supplies and crew hardware to replenish the orbital lab. Among its science payloads are mice, free-flying robots and a host of other experiments and research gear. The astronauts set up hardware today that will house the rodents and enable research into how the immune system responds to microgravity. The crew will also test the ability of tiny, autonomous robots to provide assistance with routine space chores and lab monitoring.
Commander Oleg Kononenko and fellow cosmonaut Alexey Ovchinin worked throughout the day on Russian life support maintenance. Ovchinin also researched enzyme behavior in space and photographed plants for a botany investigation.
The U.S. Cygnus resupply ship from Northrop Grumman is encapsulated atop the Antares rocket and standing at its launch pad in Virginia. The Expedition 59 crew is training for its capture at the end of the week in the midst of ongoing life science aboard the International Space Station.
The duo continued sharpening their robotics skills today as they practiced Friday’s Cygnus capture maneuvers and techniques on a computer. NASA TV will broadcast the space freighter’s launch and capture activities live.
McClain started the day setting up a mouse habitat that will house rodents to gain insight into the immune system’s response to long-term spaceflight. Saint-Jacques set up the 360° camera in Tranquility module for more virtual reality filming of crew life on the station.
Flight Engineer Christina Koch started Tuesday collecting and spinning her blood samples in a centrifuge for the Myotones muscle study. She then joined NASA astronaut Nick Hague for body measurements and ultrasound scans to research how microgravity impacts the biochemical properties of muscles.
The next U.S. spaceship to deliver goods to the International Space Station rolled out to its launch pad in Virginia today. The Expedition 59 crew is training to capture the U.S. space freighter while also filming a virtual reality experience aboard the orbital lab.
Astronauts Anne McClain and David Saint-Jacques will be waiting for Cygnus’ arrival Friday morning from inside the cupola. McClain will command the Canadarm2 robotic arm to reach out and capture Cygnus about 5:30 a.m. as Saint-Jacques backs her up. Robotics controllers will take over shortly after and remotely install the Cygnus to Unity’s Earth-facing point about two hours later.
The duo, supported by NASA astronaut Nick Hague, continued reviewing procedures and practicing robotics maneuvers today as Cygnus counts down to its Wednesday launch. NASA TV will broadcast the launch and capture activities live.
More virtual reality filming continued today and has been ongoing for several months now inside the orbital complex. The crew has been filming a 360° experience depicting life on the station for future viewing by audiences on Earth.
The Expedition 59 crew is now training to capture a U.S. cargo ship when it arrives at the International Space Station next week. The orbital lab residents are also busy researching how living in space affects the human mind and body.
Fresh off their spacewalk Monday, astronauts Anne McClain and David Saint-Jacques are now practicing to capture Northrop Grumman’s Cygnus space freighter with the Canadarm2 robotic arm. McClain will be at the robotics workstation in the cupola April 19 and command the Canadarm2 to capture Cygnus around 5:30 a.m. EDT. Saint-Jacques will back her up while Flight Engineer Nick Hague monitors Cygnus’ systems during its approach and rendezvous. The commercial cargo craft is due to launch April 17 at 4:46 p.m. from Wallops Flight Facility in Virginia.
Hague started his day with more brain research in the Japanese Kibo lab module. The NASA astronaut used a Doppler device to record his arterial blood flow waveforms. The data will help doctors understand how the brain regulates blood flow in microgravity.
The astronauts also researched how the station’s atmosphere affects breathing. The experiment studies how dust, particles and exhaled breath inflames a crewmember’s airways. Observations may reveal conditions that exacerbate or alleviate airway inflammation influencing future space missions.
SpaceX has announced April 26 as the launch date for its next Dragon cargo mission. The private space freighter will blast off from Cape Canaveral in Florida arriving at the station April 28. This time Saint-Jacques will lead the robotics capture activities while Hague backs him up.
The Expedition 59 crew has switched focus from Monday’s spacewalk to microgravity science aboard the International Space Station. Soon, the orbital residents will be unpacking a pair of U.S. space freighters.
Astronauts Anne McClain of NASA and David Saint-Jacques of the Canadian Space Agency are conducting their post-spacewalk medical checkups today. The astronauts measured their temperature, blood pressure, respiration and ear condition. After the checkups, the spacewalkers had their eyes scanned with an ultrasound device by Flight Engineer Nick Hague.
The spacewalking duo along with NASA astronaut Christina Koch also had an hour-long video debrief session with specialists on the ground. The crew and mission controllers discussed lessons they learned that could inform the planning of future spacewalks.
Koch spent most of her day on maintenance replacing science hardware inside the Combustion Integrated Rack. The research device enables safe investigations of microgravity’s impacts on solid and gaseous fuel combustion aboard the orbital lab. Hague explored how blood flows to the brain for the Cerebral Autoregulation study. The brain research uses Doppler technology that measures blood flow waveforms to help doctors understand and treat space-caused lightheadedness.
With the recent series of spacewalks now complete, the crew will soon be turning its attention to the arrival of two resupply ships. Northrop Grumman’s Cygnus cargo craft and the SpaceX Dragon will each deliver science and supplies before the end of the month to replenish the space station crew. Cygnus is due to blast off for a three-month mission attached to the station’s Unity module April 17. Dragon is targeted to liftoff at the end of April for a month-long stay at the Harmony module.
The Expedition 59 crew is going into the weekend preparing for another spacewalk on Monday. The International Space Station residents also continue microgravity research as they wait for two U.S. cargo ships to arrive before the end of the month.
Astronauts Anne McClain and David Saint-Jacques are getting their tools ready for another power upgrades spacewalk and will wrap up their final procedures review on Sunday. The spacewalkers will set their spacesuits to battery power around 8:05 a.m. EDT Monday signifying the start of their spacewalk and exit the space station’s Quest airlock.
The duo will work outside for about six-and-a-half hours installing truss jumpers to provide a redundant power source to the Canadarm2 robotic arm. McClain and Saint-Jacques will also install cables to update the station’s External Wireless Communications system. NASA TV starts its live coverage at 6:30 a.m. Monday.
Russia’s Progress 72 (72P) resupply ship delivered over 3.7 tons of food, fuel and supplies after docking to the Pirs docking compartment Thursday morning. Next up is Northrop Grumman’s Cygnus space freighter when it launches from Virginia on April 17 on a two-day ride to the station’s Unity module. SpaceX follows in late April when its Dragon cargo craft blasts off from Florida on a two-day trip to the orbital lab’s Harmony module.
Virtual reality filming and space research continued full pace inside the orbital lab today. Flight Engineer Christina Koch first strapped herself into an exercise bike to measure her aerobic capacity then set up a virtual reality camera inside the Unity module today. Nick Hague of NASA then recorded himself describing his space experiences for a short immersive, cinematic film.
Cosmonauts Oleg Kononenko and Alexey Ovchinin unloaded the new 72P and worked on an array of life science experiments in the orbital lab’s Russian segment. The duo photographed red blood samples and microbes to help doctors keep long-term crews healthy in space.
April is shaping up to be a busy month bringing three new spaceships and another spacewalk to the International Space Station. The Expedition 59 crew has already wrapped up two spacewalks this year and welcomed the first SpaceX Crew Dragon spacecraft and the latest Soyuz MS-12 crew ship in March.
Roscosmos, SpaceX and Northrop Grumman are all readying their resupply ships to blast off this month and replenish the six orbital residents. A pair of astronauts will also go on another spacewalk, this time to provide secondary power for the Canadarm2 robotic arm.
At the Baikonur Cosmodrome in Kazakhstan, the Russia’s Progress 72 cargo ship, loaded with more than 3 ½ tons of food, fuel and supplies, rolled to its launch pad Monday for final preparations for launch Thursday, April 4 at 7:01 a.m. EDT. The launch will send the unpiloted Progress on a 2-orbit rendezvous trajectory — the second ever — for an automated docking to the Pirs docking compartment three hours later. NASA TV will broadcast live the express cargo delivery to the orbital complex.
On Monday April 8, two astronauts will go on the third spacewalk of 2019. Flight Engineers Anne McClain and David Saint-Jacques will set their spacesuits to battery power around 8:05 a.m. and exit the Quest airlock. The duo will install truss jumpers on the Unity module and the Starboard truss structure to ensure the Canadarm2 stays powered in the event one of its other power units fail.
Finally, two U.S. spaceships will blast off toward the station this month from two different launch pads on the U.S. east coast. The orbital lab will be host to six different spacecraft, including two Russian Progress space freighters and two Russian Soyuz crew ships, by April 28.
Northrop Grumman will launch its 11th Cygnus cargo craft atop an Antares rocket April 17 from Wallops Flight Facility in Virginia and take a two-day trip to the station. SpaceX is readying its 17th Dragon cargo mission for an April lift off from Cape Canaveral in Florida and a three-day ride to the orbital lab.
Northrop Grumman’s Cygnus spacecraft was released from the Canadarm2 at 11:16 a.m. EST and has departed the International Space Station. After an extended mission to deploy several CubeSats in multiple orbits, Cygnus is scheduled to be deorbited on Feb. 25 to enter the Earth’s atmosphere and burn up harmlessly over the Pacific Ocean.
Expedition 58 Flight Engineers Anne McClain of NASA and David Saint-Jacques of the Canadian Space Agency used the station’s robotic arm to release the craft, dubbed the “SS John Young”, after ground controllers unbolted the cargo vehicle from the Earth-facing port of the Unity module earlier this morning.
This Commercial Resupply Services contract mission delivered dozens of new and existing investigations as Expedition 58 contributes to some hundreds of science and research studies. Highlights from the new experiments include a demonstration of 3D printing and recycling technology and simulating the creation of celestial bodies from stardust.
The Refabricator is the first-ever 3D printer and recycler integrated into one user-friendly machine. Once it’s installed in the space station, it will demonstrate recycling of waste plastic and previously 3D printed parts already on-board into high-quality filament, or 3D printer “ink.” This recycled filament will be fed into the printer as stock to make new tools and parts on-demand in space. This technology could enable closed-loop, sustainable fabrication, repair and recycling on long-duration space missions, and greatly reduce the need to continually launch large supplies of new material and parts for repairs and maintenance. The demonstration, which NASA’s Space Technology Mission and Human Exploration and Operations Directorates co-sponsored, is considered a key enabling technology for in-space manufacturing. NASA awarded a Small Business Innovation Research contract valued to Tethers Unlimited Inc. to build the recycling system.
The Experimental Chondrule Formation at the International Space Station (EXCISS) investigation will explore how planets, moons and other objects in space formed by simulating the high-energy, low-gravity conditions that were present during formation of the early solar system. Scientists plan to zap a specially formulated dust with an electrical current, and then study the shape and texture of the resulting pellets.
The Crystallization of LRRK2 Under Microgravity Conditions-2 (PCG-16) investigation grows large crystals of an important protein, leucine-rich repeat kinase 2 (LRRK2), in microgravity for analysis back on Earth. This protein is implicated in development of Parkinson’s disease, and improving our knowledge of its structure may help scientists better understand the pathology of the disease and develop therapies to treat it. LRRK2 crystals grown in gravity are too small and too compact to study, making microgravity an essential part of this research. This investigation is sponsored by the International Space Station U.S. National Laboratory, which Congress designated in 2005 to maximize its use for improving quality of life on Earth.
Cygnus launched Nov. 17, 2018, on an Antares 230 rocket from Virginia Mid-Atlantic Regional Spaceport’s Pad 0A at Wallops, and arrived at the station Nov. 19 for the company’s 10th NASA-contracted commercial resupply mission to the station.
This was the seventh flight of an enhanced Cygnus spacecraft, and the fourth using Northrop Grumman’s upgraded Antares 230 launch vehicle featuring new RD-181 engines that provide increased performance and flexibility.
