A recent provide of 8,300 kilos of scientific investigations and cargo launched from NASA’s Wallops Flight Facility in Virginia at 12:40 p.m. EST on Saturday, February 19, aboard a Northrop Grumman Cygnus resupply spacecraft, and is now touring to the Worldwide House Station.
The Cygnus spacecraft, which was launched on an Antares rocket, is scheduled to reach on the house station round 4:35 a.m. on Monday, February 21. NASA Tv, the NASA app, and company’s web site will present stay protection of the spacecraft’s method and arrival starting at 3 a.m.

NASA astronauts Raja Chari and Kayla Barron will seize Cygnus with the station’s robotic Canadarm2 upon its arrival. The spacecraft will then be put in on the Earth-facing port of the station’s Unity module.
That is Northrop Grumman’s seventeenth contracted resupply mission below the second Business Resupply Providers contract with NASA. The supply consists of vital supplies to assist dozens of the greater than 250 science and analysis investigations occurring throughout NASA’s Expedition 66 mission aboard the house station.
The scientific investigations Cygnus is carrying embody:
Defending our pores and skin
Deterioration of pores and skin tissue, a traditional a part of growing old, happens over many years. Microgravity results in modifications within the physique like growing old however that happen way more shortly, to allow them to be extra simply studied. Colgate Pores and skin Getting older will consider mobile and molecular modifications in engineered human pores and skin cells in microgravity. Outcomes could assist velocity improvement of merchandise geared toward defending pores and skin from the growing old course of on Earth.

Testing tumor medicine
MicroQuin 3D Tumor will look at the results of a therapeutic on breast and prostate most cancers cells. These cells can develop in a extra pure 3D mannequin in microgravity, which makes it simpler to characterize their construction, gene expression, cell signaling, and response to the remedy. Outcomes might present new perception into the cell protein focused by the drug and assist advance improvement of different most cancers medicine.

Staining reveals a traditional nucleus (blue) and the therapeutic (inexperienced) localized to the cell’s endoplasmic reticulum (purple). The drug forces the cytoskeleton (yellow) to break down, inducing cell dying. Credit score: Scott Robinson, MicroQuin
Bettering hydrogen sensors
The Superior Hydrogen Sensor Expertise Demonstration will take a look at new sensors for the house station’s oxygen technology system. Present sensors be certain that not one of the hydrogen enters the cabin oxygen however may be delicate to moisture, nitrogen, and different points that require them to be swapped out each 201 days. This expertise might present extra sturdy sensors for conditions the place fast substitute shouldn't be sensible, lowering the variety of spares wanted on longer house missions similar to to the Moon or Mars.

Higher batteries
House Demonstration for All Strong-State Li Ion Battery (House As-Lib), an investigation from the Japan Aerospace Exploration Company, will function the operation of a lithium-ion secondary battery able to secure, steady operation below excessive temperatures and in a vacuum surroundings. The battery makes use of strong, inorganic, and flame-retardant supplies that don't leak, making it safer and extra dependable. Outcomes might show the battery’s efficiency for varied potential makes use of in house and different planetary environments. Strong-state batteries even have potential functions in harsh environments and the automotive and aerospace industries.

Crops in house
Present programs for rising vegetation in house use soil or a development medium. These programs are small and don't scale nicely in an area surroundings attributable to mass, containment, upkeep, and sanitation points. To deal with these points, eXposed Root On-Orbit Check System (XROOTS) will use water- and air-based strategies as a substitute, lowering general system mass. Outcomes might present perception into the event of larger-scale programs to develop meals crops for future house exploration and habitats. Elements of the system might additionally improve plant cultivation in greenhouses on Earth and contribute to higher meals safety.

Bettering fireplace security
Strong Gas Ignition and Extinction (SoFIE) will allow research of the flammability of supplies and ignition of fires in real looking atmospheric situations. This facility makes use of the Combustion Built-in Rack (CIR), which permits for testing at totally different oxygen concentrations and pressures that characterize present and deliberate house exploration missions. Gravity influences flames on Earth, however in microgravity, fireplace acts in a different way and might behave in surprising methods aboard the house station. Some proof means that fires could also be extra hazardous in diminished gravity. Outcomes might assist guarantee crew security by enhancing design of extravehicular exercise fits, and cabin supplies, enhance our means to find out one of the best methods for suppressing fires in house.
Findings from these and different investigations aboard the house station will contribute to protecting astronauts wholesome throughout long-duration house journey and show applied sciences for future human and robotic exploration missions as a part of NASA’s Moon and Mars efforts, together with lunar missions by the company’s Artemis program.
Cygnus can even ship vital hardware to be put in through the upcoming ISS Roll-Out Photo voltaic Array (IROSA) spacewalks, in addition to different parts for the profitable functioning of astronaut life on the house station, similar to a trash deployer and acoustic covers for the waste administration system.
This Cygnus mission is the primary to function enhanced capabilities that can permit the spacecraft to carry out a reboost, utilizing its engines to regulate the house station’s orbit as a typical service for NASA. The company has one reboost is deliberate whereas Cygnus is related to the orbiting laboratory. A take a look at of the maneuver was carried out in 2018 throughout Cygnus’ ninth resupply mission.
Cygnus will stay on the house station till Might earlier than it deploys CubeSats, then disposes of a number of thousand kilos of trash throughout its re-entry into Earth’s environment, which is able to end in its destruction.
