A Russian space freighter has rolled out to its launch pad ready to resupply the International Space Station this weekend. Meanwhile, the Expedition 63 crew is ramping up its preparations for the first Commercial Crew mission and more cargo activities planned for May.
Commander Chris Cassidy of NASA is looking forward to welcoming a pair of fellow NASA astronauts aboard the station at the end of May. Commercial Crew astronauts Robert Behnken and Doug Hurley are preparing for their launch aboard the SpaceX Crew Dragon spaceship scheduled for May 27 at 4:23 p.m. The first crew to launch from U.S. soil since 2011 will dock one day later to the station and join Expedition 63 for a months-long mission.
The crew aboard the orbiting lab is also due to receive its first space delivery on Saturday at 1:12 a.m. EDT. Russia’s Progress 75 (75P) cargo craft will carry several tons of crew supplies and station hardware and automatically dock to the aft port of the Zvezda service module. The 75P will lift off on Friday at 9:51 p.m. from the Baikonur Cosmodrome in Kazakhstan for the short three-and-a-half hour flight to the station.
Cosmonauts Anatoly Ivanishin and Ivan Vagner are training for Saturday morning’s automated arrival of the 75P. The duo practiced remotely-controlled emergency rendezvous and docking techniques in the unlikely event the 75P wouldn’t be able to approach and dock to the station on its own.
Meanwhile, the U.S. Northrop Grumman Cygnus cargo craft is being readied to end its stay attached to the station’s Unity module on May 11. Cassidy and Ivanishin packed trash and discarded gear inside Cygnus today for a fiery disposal in the atmosphere above the Pacific Ocean.
Finally, JAXA (Japan Aerospace Exploration Agency) is targeting May 20 for the launch of its ninth cargo mission to the station. JAXA’s HTV (H-II Transfer Vehicle) cargo craft, nicknamed Kounotori, would take a five-day trip before being captured and installed to the station with the Canadarm2 robotic arm.
Expedition 63 Commander Chris Cassidy of NASA continued working on a variety of science hardware throughout the International Space Station today. His two crewmates worked in the orbiting lab’s Russian segment on their complement of science and maintenance.
Cassidy started Tuesday in the Japanese Kibo laboratory module setting up a small satellite deployer. CubeSats are installed into the device, which is then loaded into Kibo’s airlock. Then the deployer is positioned in the vacuum of space to eject the tiny shoebox-sized satellites into Earth orbit.
In the afternoon, Cassidy moved over to the U.S. Destiny laboratory module and swapped computer parts inside the Fluids and Combustion Facility (FCF). The FCF consists of two refrigerator-sized research racks enabling safe observations of the behavior of fluids and flames in microgravity. Scientists use the data to design advanced fuel transfer systems and increase fire safety.
Russian Flight Engineers Anatoly Ivanishin and Ivan Vagner logged their meals today to understand how spaceflight affects a crewmember’s nutrition and metabolism. The duo then worked throughout the day on life support maintenance while continuing to get used to life onboard the station.
Russia’s next cargo craft to resupply the station is completing final processing and assembly at the Baikonur Cosmodrome in Kazakhstan. The Progress 75 (75P) space freighter packed with several tons of food, fuel and supplies is due to launch on Friday at 9:51 p.m. EDT. The 75P will make a two-orbit, three-and-a-half hour trip and automatically dock to the aft port of the Zvezda service module.
The International Space Station is orbiting higher today as three Expedition 61 crewmates get ready to return to Earth in two weeks. Meanwhile, two astronauts are finalizing preparations for a spacewalk early Saturday.
Russia’s Progress 74 cargo craft fired its engines twice boosting the space station’s altitude Thursday morning. The orbital adjustment sets up the correct trajectory for the undocking and landing of the Soyuz MS-13 crew ship on Feb. 6.
The Soyuz MS-13 will be commanded by Alexander Skvortsov returning home with astronauts Christina Koch and Luca Parmitano. The trio will parachute to a landing in Kazakhstan at 4:14 a.m. EST (3:14 p.m. Kazakh time). Koch will have lived in space continuously for 328 days, second only to U.S. astronaut Scott Kelly with 340 days.
The third spacewalk of January 2020 is set to begin Saturday at 6:50 a.m. EST with live NASA TV coverage getting under way at 5:30 a.m. Parmitano with NASA Flight Engineer Andrew Morgan will complete the complex thermal repairs on the Alpha Magnetic Spectrometer, a dark matter and antimatter detector.
Koch and fellow NASA astronaut Jessica Meir will assist the spacewalkers with the Canadarm2 robotic arm and are getting up to speed with the fine-tuned robotics maneuvers. They were joined by Morgan and Parmitano as the quartet reviewed spacewalk tasks and procedures.
The Starliner spacecraft sits atop an Atlas V rocket from United Launch Alliance counting down to a liftoff Friday at 6:36 a.m. EST. This will be Boeing’s first Orbital Flight Test of the uncrewed vehicle that will dock to the station Saturday at 8:27 a.m.
NASA astronauts Jessica Meir and Christina Koch are getting ready for duty Saturday morning when they will monitor Starliner’s automated rendezvous and docking with the orbiting lab. The duo will then conduct leak checks, open the hatch and ingress the vehicle to begin a week of docked operations. Starliner is also delivering about 600 pounds of cargo to the crew and will return science samples to Earth after its departure on Dec. 28.
Meanwhile, microgravity science is always ongoing aboard the station to improve life for humans on Earth and in space. Today, NASA Flight Engineer Andrew Morgan studied how weightlessness affects an optical material that can control the reflection and absorption of light. Results could improve solar power technology and electronic mobile displays.
Meir had her eyes scanned with an ultrasound device by ESA (European Space Agency) Commander Luca Parmitano for a look at her cornea, lens and optic nerve. She had a second eye exam using optical coherence tomography for a view of her retina.
The flight engineers in the Russian side of the space station checked on a pair of docked spaceships while working science and maintenance. Cosmonaut Oleg Skripochka charged electronics gear in the Soyuz MS-15 crew ship. He also worked on plumbing systems in the Progress 74 cargo craft. Cosmonaut Alexander Skvortsov set up hardware for an Earth imaging study that explores the effects of natural and manmade catastrophes.
NASA Television and the agency’s website are now live broadcasting the expected arrival of a Russian Progress cargo spacecraft set to dock to the Pirs compartment on the International Space Station’s Russian segment at 5:38 a.m.
The Progress 74 spacecraft is carrying almost three tons of food, fuel and supplies for the Expedition 61 crew aboard the station. Progress will arrive after making 49 orbits of Earth in three days since its launch Friday, Dec. 6 at 4:34 a.m.
Three days after its launch from Florida, the SpaceX Dragon cargo spacecraft was installed on the Earth-facing side of the International Space Station’s Harmony module at 7:47 a.m. EST.
The 19th contracted commercial resupply mission from SpaceX delivers more than 5,700 pounds of research, crew supplies and hardware to the orbiting laboratory.
Here’s some of the science arriving at station:
Keeping Bones and Muscles Strong
Rodent Research-19 (RR-19) investigates myostatin (MSTN) and activin, molecular signaling pathways that influence muscle degradation, as possible targets for preventing muscle and bone loss during spaceflight and enhancing recovery following return to Earth. This study also could support the development of therapies for a wide range of conditions that cause muscle and bone loss on Earth.
Checking for Leaks
NASA is launching Robotic Tool Stowage (RiTS), a docking station that allows Robotic External Leak Locator (RELL) units to be stored on the outside of space station, making it quicker and simpler to deploy the instruments. The leak locator is a robotic, remote-controlled tool that helps mission operators detect the location of an external leak and rapidly confirm a successful repair. These capabilities can be applied to any place that humans live in space, including NASA’s lunar Gateway and eventually habitats on the Moon, Mars, and beyond.
After Dragon spends approximately one month attached to the space station, the spacecraft will return to Earth with cargo and research.
Next up, the station crew will be preparing for the arrival early Monday morning of a second resupply spacecraft. The Russian Progress 74 that launched Friday at 4:34 a.m. is expected to dock to the Pirs compartment on the station’s Russian segment at 5:38 a.m. Monday, Dec. 9. NASA TV and the agency’s website will provide live coverage of Progress rendezvous and docking at 4:45 a.m.
SpaceX will launch its 19th Dragon resupply ship aboard a Falcon 9 rocket on Wednesday at 12:51 p.m. EST from Kennedy Space Center in Florida. Dragon is delivering nearly three tons of cargo to the orbiting lab including new science hardware such as the Confined Combustion study, Japan’s Hyperspectral Imager Suite (HISUI) and the AzTechSat-1 cubesat developed by Mexican students.
Commander Luca Parmitano and Flight Engineer Andrew Morgan are training to capture Dragon with the Canadarm2 robotic arm when it arrives Saturday at 5:58 a.m. Robotics controllers will take command of the Canadarm2 and then install Dragon to the Harmony module’s Earth-facing port.
Parmitano and Morgan wrapped up a spacewalk on Monday having replaced a thermal pump system on the station’s cosmic particle detector. They joined fellow astronauts Jessica Meir and Christina Koch at the end of the day Tuesday with a call to Mission Control about their spacewalk experience.
The space station is also preparing for the arrival of Russia’s Progress 74 (74P) cargo craft set for launch on Friday at 4:34 a.m. The 74P will take a three-day trip to the station and dock Monday Dec. 9 at 5:38 a.m. Cosmonauts Alexander Skvortsov and Oleg Skripochka checked out the tele-robotically operated rendezvous unit (TORU) today in the unlikely event they would need to remotely maneuver the 74P to a docking.
Traveling about 259 miles over northwest China, the unpiloted Russian Progress 73 cargo ship docked at 11:29 a.m. EDT to the Pirs docking compartment on the Russian segment of the complex.
In addition to the arrival of Progress today, the six crewmembers aboard the space station welcomed SpaceX’s cargo Dragon spacecraft on July 27, two days after launching on a Falcon 9 rocket from Launch Complex 40 on Cape Canaveral Air Force Station in Florida.
On July 20, the Soyuz MS-13 spacecraft arrived to the space station carrying NASA astronaut Andrew Morgan and Luca Parmitano of ESA (European Space Agency) and Alexander Skvortsov of the Russian space agency Roscosmos. Their arrival restored the station’s crew complement to six. They joined NASA astronauts Nick Hague, Christina Koch and Expedition 60 Commander Alexey Ovchinin of Roscosmos.
Carrying almost three tons of food, fuel and supplies for the International Space Station crew, the unpiloted Russian Progress 73 cargo spacecraft launched at 8:10 a.m. EDT (5:10 p.m. Baikonur time) from the Baikonur Cosmodrome in Kazakhstan.
The resupply ship reached preliminary orbit and deployed its solar arrays and navigational antennas as planned. Following a 2-orbit rendezvous, the Russian cargo spacecraft will dock to the orbiting laboratory at 11:35 a.m. NASA Television coverage of rendezvous and docking will begin at 10:45 a.m.
Progress 73 will remain docked at the station for five months before departing in December for its deorbit in Earth’s atmosphere.
The Progress is the second of two cargo resupply ships delivering supplies to the six crewmembers aboard the space station this month. SpaceX’s cargo Dragon spacecraft attached to station on Saturday, July 27, two days after launching on a Falcon 9 rocket from Launch Complex 40 on Cape Canaveral Air Force Station in Florida.
