"The agency announced the CRS-21 mission is scheduled for December 5th at 11:35 a.m. Eastern Time. A Falcon 9 rocket will lift off from Space Launch Complex 39A at NASA’s Kennedy Space Center in Florida, carrying the Dragon spacecraft to low Earth orbit. The CRS-21 mission will be the first resupply mission that will utilize SpaceX's upgraded version of the cargo Dragon capsule, which is capable of carrying 50% more payload mass. Dragon is capable of launching a bit over 13,000 pounds of cargo and returning around 6,000 pounds safely, SpaceX says it is “the only spacecraft currently flying that is capable of returning significant amounts of cargo to Earth.”
