Dragon Attached to Station for Month-Long Stay












SpaceX - Falcon 9 / Dragon CRS-19 patch.

December 8, 2019

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.

Astronauts Capture Dragon Filled With Brand New Science

International Space Station was traveling more than 262 miles over the south Pacific Ocean, Expedition 61 Commander Luca Parmitano of ESA (European Space Agency) grappled Dragon at 5:05 a.m. EST using the space station’s robotic arm Canadarm2 with NASA astronaut Andrew Morgan acting as a backup.

Ground controllers will now send commands to begin the robotic installation of the spacecraft on bottom of the station’s Harmony module. NASA Television coverage of installation is scheduled to begin at 7:30 a.m. Coverage may be adjusted as needed.

SpaceX CRS-19 Dragon capture

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.

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 malting 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 behavior 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.

SpaceX CRS-19 Dragon berthing

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.
