What You Need to Know about NASA’s SpaceX Crew-8 Mission

Source: NASA

Four new crew members are preparing to launch to the International Space Station as part of NASA’s SpaceX Crew-8 mission.
NASA astronauts Matthew Dominick, Michael Barratt, and Jeanette Epps, and Roscosmos cosmonaut Alexander Grebenkin will lift off from Launch Complex 39A at NASA’s Kennedy Space Center in Florida to perform research, technology demonstrations, and maintenance activities aboard the microgravity laboratory.
The flight is the eighth crew rotation mission with SpaceX to station, and the ninth human spaceflight as part of NASA’s Commercial Crew Program. The cadre will fly aboard the SpaceX Dragon spacecraft, named Endeavour, which previously flew NASA’s SpaceX Demo Mission-2, Crew-2 and Crew-6, in addition to Axiom Mission 1, the first commercial astronaut mission to the space station.
As teams progress through Dragon milestones for Crew-8, they also are preparing a first-flight Falcon 9 booster for the mission. Once all rocket and spacecraft system checkouts are complete and all components are certified for flight, teams will mate Dragon to the Falcon 9 rocket in SpaceX’s hangar at the launch site. The integrated spacecraft and rocket will then be rolled to the pad and raised to vertical for a dry dress rehearsal with the crew and an integrated static fire test prior to launch.

Matthew Dominick will serve as commander for Crew-8, his first spaceflight, after being selected as an astronaut by NASA in 2017. He is from Wheat Ridge, Colorado, and earned a bachelor’s degree in electrical engineering from the University of San Diego, California, and a master’s in systems engineering from the Naval Postgraduate School in Monterey, California. He is an active-duty U.S. Navy astronaut. He graduated from the U.S. Naval Test Pilot School in Patuxent River, Maryland, and then served as a test pilot specializing in testing aircraft carriers’ landings and catapult launches.

Michael Barratt is the Crew-8 pilot, making his third visit to the space station. In 2009, Barratt served as a flight engineer for Expeditions 19/20 as the station transitioned its standard crew complement from three to six and performed two spacewalks. He flew aboard the space shuttle Discovery in 2011 on STS-133, which delivered the Permanent Multipurpose Module and fourth Express Logistics Carrier. He has spent a total of 212 days in space. Born in Vancouver, Washington, he considers Camas, Washington, to be his hometown. Barratt earned a bachelor’s in zoology from the University of Washington, Seattle, and a Doctor of Medicine degree from Northwestern University in Chicago. He completed residencies in internal and aerospace medicine at Northwestern along with a master’s degree at Wright State University in Dayton, Ohio. After nine years as a NASA flight surgeon and project physician, Barratt joined the astronaut corps in 2000. During Expedition 70/71 on the International Space Station, he will serve as a mission specialist.
Jeanette Epps was selected by NASA as an astronaut in 2009 and is a mission specialist aboard Crew-8, her first spaceflight, working with the commander and pilot to monitor the spacecraft during the dynamic launch and re-entry phases of flight. She is from Syracuse, New York, and earned a bachelor’s in physics from LeMoyne College in Syracuse, and a master’s in science and a doctorate in aerospace engineering from the University of Maryland at College Park. Prior to joining NASA, she worked at Ford Motor Co. and the Central Intelligence Agency. She was selected as an astronaut in July 2009 and has served on the Generic Joint Operation Panel working on space station crew efficiency, as a crew support astronaut for two expeditions, and as lead capsule communicator at NASA Johnson. Epps previously was assigned to NASA’s Boeing Starliner-1 mission. NASA reassigned Epps to allow Boeing time to complete development of Starliner while also continuing plans for astronauts to gain spaceflight experience for future mission needs.

Roscosmos cosmonaut Alexander Grebenkin, who graduated from Irkutsk High Military Aviation School, Irkutsk, Russia, majoring in engineering, maintenance, and repair of aircraft radio navigation systems, also is flying on his first mission. He graduated from Moscow Technical University of Communications and Informatics with a degree in radio communications, broadcasting, and television. Grebenkin will serve as a flight engineer during Expeditions 70/71 aboard the International Space Station.

Lifting off from Launch Pad 39A on a Falcon 9 rocket, Dragon will accelerate to approximately 17,500 mph, to dock with the space station.
Once in orbit, the crew and SpaceX mission control in Hawthorne, California, will monitor a series of automatic maneuvers that will guide Dragon to the forward-facing port of the station’s Harmony module. The spacecraft is designed to dock autonomously, but the crew can take control and pilot manually, if necessary.
After docking, Crew-8 will be welcomed inside the station by the seven-member crew of Expedition 70 and conduct several days of handover activities with the departing astronauts of NASA’s SpaceX Crew-7 mission. After a handover period, NASA astronaut Jasmin Moghbeli, ESA (European Space Agency) astronaut Andy Mogensen, JAXA (Japan Aerospace Exploration Agency) astronaut Satoshi Furukawa, and Roscosmos cosmonaut Konstantin Borisov of Crew-7 will undock from the space station and splash down off the coast of Florida.
Crew-8 will conduct new scientific research to prepare for human exploration beyond low Earth orbit and benefit humanity on Earth. Experiments include using stem cells to create organoid models to study degenerative diseases, studying the effects of microgravity and UV radiation on plants at a cellular level, and testing whether wearing pressure cuffs on the legs could prevent fluid shifts and reduce health problems in astronauts. These are just a few of the more than 200 scientific experiments and technology demonstrations taking place during their mission.
While aboard the orbiting laboratory, Crew-8 will see the arrival of both the SpaceX Dragon and the Roscosmos Progress cargo spacecraft. Crew-8 also is expected to welcome the agency’s Boeing Crew Flight Test astronauts and the first cargo flight of Sierra Space’s Dream Chaser. A Soyuz spacecraft with three new crew members, including NASA astronaut Tracy Dyson, will also launch during their stay, and the Soyuz carrying NASA astronaut Loral O’Hara will return to Earth.
After completing a short handover with Crew-9 at the completion of the mission, Dragon with the four crew members aboard will autonomously undock, depart the space station, and re-enter Earth’s atmosphere. After splashdown off Florida’s coast, a SpaceX recovery vessel will pick up the spacecraft and crew, who then will be helicoptered back to shore.
Commercial crew missions enable NASA to maximize use of the space station, where astronauts have lived and worked continuously for more than 23 years testing technologies, performing research, and developing the skills needed to operate future commercial destinations in low Earth orbit, and explore farther from Earth. Research conducted on the space station provides benefits for people on Earth and paves the way for future long-duration trips to the Moon and beyond through NASA’s Artemis missions.

Overview for NASA’s Northrop Grumman 20th Commercial Resupply Mission

Source: NASA

NASA, Northrop Grumman, and SpaceX are targeting 12:29 p.m. EST on Monday, Jan. 29, for the next launch to deliver science investigations, supplies, and equipment to the International Space Station. Filled with more than 7,800 pounds of supplies, the Cygnus cargo spacecraft, carried atop the SpaceX Falcon 9 rocket, will launch from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. This launch is the 20th Northrop Grumman commercial resupply services mission to the orbital laboratory for the agency. The backup launch opportunity will be at 12:07 p.m. Tuesday, Jan. 30.
Live launch coverage will begin at 12:15 p.m. and air on NASA+, NASA Television, the NASA app, YouTube, and on the agency’s website, with prelaunch events starting Wednesday, Jan. 24. Learn how to stream NASA TV through a variety of platforms
Learn more at:  nasa.gov/northropgrumman

Arrival & Departure
The Cygnus spacecraft will arrive at the orbiting laboratory at 3:35 a.m. Wednesday, Jan. 31, filled with supplies, hardware, and critical materials to directly support dozens of science and research investigations during Expeditions 70 and 71. NASA astronaut Jasmin Moghbeli will capture Cygnus using the station’s robotic arm, and NASA astronaut Loral O’Hara will act as backup.
After capture, the spacecraft will be installed on the Unity module’s Earth-facing port and will spend about six months connected to the orbiting laboratory before departing in May. Cygnus also provides the operational capability to reboost the station’s orbit.
After departure, the Kentucky Re-entry Probe Experiment-2 (KREPE-2), stowed inside Cygnus, will take measurements to demonstrate a thermal protection system for spacecraft and their contents during re-entry in Earth’s atmosphere, which can be difficult to replicate in ground simulations.
Live coverage of Cygnus’ arrival will begin at 2 a.m., Wednesday, Jan. 31.

Research Highlights
Scientific investigations traveling in the Cygnus spacecraft include tests of a 3D metal printer, semiconductor manufacturing, and thermal protection systems for re-entry to Earth’s atmosphere.
3D Printing in Space

An investigation from ESA (European Space Agency), Metal 3D Printer tests additive manufacturing or 3D printing of small metal parts in microgravity.
“This investigation provides us with an initial understanding of how such a printer behaves in space,” said Rob Postema of ESA. “A 3D printer can create many shapes, and we plan to print specimens, first to understand how printing in space may differ from printing on Earth and second to see what types of shapes we can print with this technology. In addition, this activity helps show how crew members can work safely and efficiently with printing metal parts in space.”
Results could improve understanding of the functionality, performance, and operations of metal 3D printing in space, as well as the quality, strength, and characteristics of the printed parts. Resupply presents a challenge for future long-duration human missions. Crew members could use 3D printing to create parts for maintenance of equipment on future long-duration spaceflight and on the Moon or Mars, reducing the need to pack spare parts or to predict every tool or object that might be needed, saving time and money at launch.
Advances in metal 3D printing technology also could benefit potential applications on Earth, including manufacturing engines for the automotive, aeronautical, and maritime industries and creating shelters after natural disasters.
Semiconductor Manufacturing in Microgravity

Manufacturing of Semiconductors and Thin-Film Integrated Coatings (MSTIC) examines how microgravity affects thin films that have a wide range of uses.
This technology could enable autonomous manufacturing to replace the many machines and processes currently used to make a wide range of semiconductors, potentially leading to the development of more efficient and higher-performing electrical devices.
Manufacturing semiconductor devices in microgravity also may improve their quality and reduce the materials, equipment, and labor required. On future long-duration missions, this technology could provide the capability to produce components and devices in space, reducing the need for resupply missions from Earth. The technology also has applications for devices that harvest energy and provide power on Earth.
Modeling Atmospheric Re-Entry

Scientists who conduct research on the space station often return their experiments to Earth for additional analysis and study. But the conditions that spacecraft experience during atmospheric reentry, including extreme heat, can have unintended effects on their contents. Thermal protection systems used to shield spacecraft and their contents are based on numerical models that often lack validation from actual flight, which can lead to significant overestimates in the size of system needed and take up valuable space and mass. Kentucky Re-entry Probe Experiment-2 (KREPE-2), part of an effort to improve thermal protection system technology, uses three capsules outfitted with different heat shield materials and a variety of sensors to obtain data on actual reentry conditions.
“Building on the success of KREPE-1, we have improved the sensors to gather more measurements and improved the communication system to transmit more data,” said Alexandre Martin, principal investigator at the University of Kentucky. “We have the opportunity to test several heat shields provided by NASA that have never been tested before, and another manufactured entirely at the University of Kentucky, also a first.”
The capsules can be outfitted for other atmospheric re-entry experiments, supporting improvements in heat shielding for applications on Earth, such as protecting people and structures from wildfires.
Remote Robotic Surgery

Robotic Surgery Tech Demo tests the performance of a small robot that can be remotely controlled from Earth to perform surgical procedures. Researchers plan to compare procedures in microgravity and on Earth to evaluate the effects of microgravity and time delays between space and ground.
The robot uses two “hands” to grasp and cut rubber bands, which simulate surgical tissue and provide tension that is used to determine where and how to cut, according to Shane Farritor, chief technology officer at Virtual Incision Corp., developer of the investigation with the University of Nebraska.
Longer space missions increase the likelihood that crew members may need surgical procedures, whether simple stiches or an emergency appendectomy. Results from this investigation could support development of robotic systems to perform these procedures. In addition, the availability of a surgeon in rural areas of the country declined nearly a third between 2001 and 2019. Miniaturization and the ability to remotely control the robot help make surgery available anywhere and anytime on Earth. 
NASA has sponsored research on miniature robots for more than 15 years. In 2006, remotely operated robots performed procedures in the underwater NASA’s Extreme Environment Mission Operations (NEEMO) 9 mission. In 2014, a miniature surgical robot performed simulated surgical tasks on the zero-g parabolic airplane.
Growing Cartilage Tissue in Space

Compartment Cartilage Tissue Construct demonstrates two technologies, Janus Base Nano-Matrix and Janus Base Nanopiece. Nano-Matrix is an injectable material that provides a scaffold for formation of cartilage in microgravity, which can serve as a model for studying cartilage diseases. Nanopiece delivers an RNA (ribonucleic acid)-based therapy to combat diseases that cause cartilage degeneration.
Cartilage has a limited ability to self-repair and osteoarthritis is a leading cause of disability in older patients on Earth. Microgravity can trigger cartilage degeneration that mimics the progression of aging-related osteoarthritis but happens more quickly, so research in microgravity could lead to faster development of effective therapies. Results from this investigation could advance cartilage regeneration as a treatment for joint damage and diseases on Earth and contribute to development of ways to maintain cartilage health on future missions to the Moon and Mars.

SpaceX’s Falcon 9 rocket will launch the Northrop Grumman Cygnus spacecraft to the International Space Station

Hardware  
Hydrogen Dome Assembly includes all  hydrogen and oxygen electrolysis replacement components within the International Space Station’s Oxygen Generation Assembly. These items are contained in a sub-ambient dome maintained at near vacuum pressure, designed to contain an explosion or fire in the electrolysis cell stack during operation. The dome provides a second barrier to protect against cabin air internal leakage and external leakage into the rack environment, and is pressurized with nitrogen gas for launch. This will launch as an  on-orbit spare.
Ion Exchange Bed — The ion exchange bed replacement unit consists of a pair of tubes in series containing ion exchange resins, which remove organic acids from the catalytic reactor effluent, and microbial check valve resin, which injects iodine into the water as a biocide agent. This will launch  as an on-orbit spare.
Catalytic Reactor — The catalytic reactor replacement unit oxidizes volatile organics from the wastewater so they can be removed by the gas separator and ion exchange bed replacement units as part of the station’s water recycling system. This will launch as an on-orbit spare.
Biocide Maintenance Canister — The Internal Thermal Control System Coolant Maintenance Assembly is designed to administer o-phthalaldehyde, a biocide used to purify the internal cooling loops in the Destiny laboratory, and the Harmony, Tranquility, Columbus, and Japanese Experiment Modules, to prevent the growth of microorganisms in the thermal control system. This unit will replace the current one installed in the laboratory.
Cylinder Flywheel — The ARED (Advanced Resistive Exercise Device) cylinder-flywheel assemblies provide the resistive loads for astronaut anaerobic exercise. The cylinder flywheels impart inertial forces to simulate Earth’s gravity during exercise.
International Space Station Roll Out Solar Array Modification Kit 7 – This upgrade kit consists of upper, mid, and lower struts (one each for left and right), a backbone, brackets, and support hardware for the new solar panels. This is the third in series of four modification kits needed to support the installation of the fourth set of upgraded solar arrays. The new arrays are designed to augment the station’s original solar arrays which have degraded over time. The replacement solar arrays are installed on top of existing arrays to provide a net increase in power with each array generating more than 20 kilowatts of power.
Urine Processor Assembly Pressure Control and Pump Assembly — The assembly evacuates the urine distillation assembly at startup and periodically purges non-condensable gases and water vapor and pumps them to the separator plumbing assembly. The purge pump housing and pressure control and pump assembly manifolds are liquid cooled to promote steam condensation, thereby reducing the volume of the purge gas. All these systems make up the system used to covert urine to drinking water.
Collection Packet and Adapter — Required for minimal, nominal water microbial sampling. In-flight water quality assessment is needed to assure that water of acceptable, defined quality will be available aboard the space station.

Live coverage of the launch from Cape Canaveral Space Force Station in Cape Canaveral, Florida, will air on NASA TV, NASA+ and the agency’s website. Live coverage will begin at 12:15 p.m.
Live coverage of Cygnus’ rendezvous and capture at the space station will begin at 3:35 a.m. Jan. 31. Read more about how to watch and engage.

NASA: Let’s Ketchup on International Space Station Tomato Research

Source: NASA

Growing food aboard the International Space Station is one of the many research investigations ripe for long duration spaceflight missions to the Moon and Mars.
NASA astronaut Frank Rubio recently shared the saucy story of two rogue tomatoes, which he had accidentally lost track of while harvesting for the eXposed Root On-Orbit Test System (XROOTS) experiment he conducted aboard the space station in 2022. The experiment uses hydroponic and aeroponic techniques to grow plants without soil or other growth media and could provide suitable solutions for plant systems needed for future space exploration missions.
[embedded content]
While celebrating the space station’s 25th anniversary of operations, Expedition 70 crew members revealed they found the lost tomatoes, joking that Rubio did not eat the tomatoes as they suspected. Despite being nearly a year after the initial disappearance of the tomatoes, the fruit was found in a plastic bag dehydrated and slightly squished. Other than some discoloration, it had no visible microbial or fungal growth.
During his U.S. record-breaking 371-day stay aboard station, Rubio also conducted another a-peeling experiment for the VEG-05 study, which helps address the need for a continuous fresh-food production system in space. This experiment used the space station’s Veggie facility to grow dwarf tomatoes focusing on the impact of light quality and fertilizer on fruit production, microbial food safety, nutritional value, and taste acceptability by the crew.
While the rogue tomatoes found from the XROOTS experiment will not be returning to Earth for analysis as they were discarded, plant research aboard space station continues with Plant Habitat-03, returning to Earth during the upcoming splashdown of SpaceX’s 29th commercial resupply mission. Plant Habitat-03 is one of the first multi-generational plant studies aboard the space station which could help researchers assess whether genetic adaptations in one generation of plants grown in space can transfer to the next. Results from this study could help identify genetic elements that increase the adaptability of plants to spaceflight providing insight into how to grow repeated generations of crops to provide food and other services on future space missions.
The benefits of growing plants in space don’t stop there, astronauts report there are psychological benefits to time spent gardening, increasing their quality of life in space, and boosting their morale. Research aboard the space station is advancing the technology and scientific knowledge needed to successfully grow plants in space and help humans push the boundaries of space travel. This work also helps efforts to improve plants grown for food and other important uses here on Earth.
