Last night, SpaceX launched its first generation Dragon capsule on its twentieth — and final — resupply run to the International Space Station.

The launch marks the Dragon’s last mission as the capsule makes way for SpaceX’s updated and improved Dragon 2 capsule, which will begin making resupply runs to the space station in October.
