A SpaceX Dragon cargo spacecraft has delivered more than 5,700 pounds of NASA cargo and science investigations to the ISS, including studies of malting barley in microgravity, the spread of fire, and bone and muscle loss.
Dragon joined three other spacecraft currently at the station. Expedition 61 Commander Luca Parmitano of ESA (European Space Agency) grappled Dragon with NASA astronaut Andrew Morgan acting as a backup. NASA’s Jessica Meir assisted the duo by monitoring telemetry during Dragon’s approach.
This delivery, SpaceX’s 19th cargo flight to the space station under NASA’s Commercial Resupply Services contract, will support dozens of new and existing investigations. NASA’s research and development work aboard the space station contributes to the agency’s deep space exploration plans, including future Moon and Mars missions. Here are details about some of the scientific investigations.
A better picture of Earth’s surface
The Hyperspectral Imager Suite (HISUI) is a next-generation, hyperspectral Earth imaging system. Every material on Earth’s surface – rocks, soil, vegetation, snow/ice and human-made objects – has a unique reflectance spectrum. HISUI provides space-based observations for tasks such as resource exploration and applications in agriculture, forestry and other environmental areas.
Malting barley in microgravity
Malting ABI Voyager barley seeds in microgravity tests an automated procedure and compares malt produced in space and on the ground for genetic and structural changes. Understanding how barley responds to microgravity could identify ways to adapt it for nutritional use on long-duration spaceflights.
Spread of fire
The Confined Combustion investigation examines the behaviour of flames as they spreads in differently shaped confined spaces in microgravity. Studying flames in microgravity gives researchers a better look at the underlying physics and basic principles of combustion by removing gravity from the equation.
Keeping bones and muscles strong
Rodent Research investigates myostatin (MSTN) and activin, molecular signalling 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.
