Three\u00a0days after its launch from Florida, the SpaceX Dragon cargo spacecraft was installed on the Earth-facing side of the\u00a0International Space Station<\/a>\u2019s\u00a0Harmony module at 7:47 a.m.\u00a0EST.<\/p>\n The 19th contracted commercial resupply mission\u00a0from SpaceX\u00a0delivers\u00a0more than 5,700 pounds of\u00a0research, crew supplies and hardware\u00a0to the orbiting laboratory.<\/p>\n Here\u2019s some of the science arriving at station:<\/p>\n Keeping Bones and Muscles Strong<\/strong> Checking for Leaks<\/strong> After Dragon spends approximately one month attached to the space station, the spacecraft will return to Earth with cargo and research.<\/p>\n 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\u00a0dock to the Pirs compartment<\/a>\u00a0on the station\u2019s Russian segment at 5:38 a.m. Monday, Dec. 9.

\nRodent Research-19 (RR-19<\/a>) 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.<\/p>\n
\nNASA is launching Robotic Tool Stowage (RiTS), a docking station that allows Robotic External Leak Locator (RELL<\/a>) 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\u2019s lunar Gateway and eventually habitats on the Moon, Mars, and beyond.<\/p>\nDragon Attached to Station for Month-Long Stay<\/h2>\n<\/p>\n
Dec. 8, 2019: International Space Station Configuration. Four spaceships are parked to the space station including the SpaceX Dragon space freighter, the Northrop Grumman Cygnus resupply ship and Russia\u2019s Soyuz MS-13 and MS-15 crew ships. <\/p>\n
