Overview

Cargo Dragon (Dragon 2 Cargo variant, also called Dragon C2) is an uncrewed resupply spacecraft developed by SpaceX to deliver supplies, experiments and equipment to the International Space Station under NASA's Commercial Resupply Services (CRS) programme. It is the successor to Dragon 1, which flew two demonstration flights and then CRS-1 to CRS-20 between 2010 and 2020.

Cargo Dragon's defining advantage is its ability to return payloads to Earth — up to 3,000 kg of pressurised cargo including science experiments, biological samples and station hardware. All other active ISS cargo vehicles (Cygnus, Progress) burn up on re-entry, meaning critical experiments can only return via Dragon. This makes it an irreplaceable part of the ISS science programme.

Like its crewed sibling (Crew Dragon), Cargo Dragon launches on Falcon 9 from Kennedy Space Centre and docks autonomously to the station. It does not carry a launch abort system, life support or crew displays.

Dragon 1 vs Cargo Dragon 2

The original Dragon 1 flew CRS-1 through CRS-20 (2012–2020) and was berthed to the ISS using the station's robotic arm. Cargo Dragon 2 (CRS-21 onwards) docks autonomously, carries more cargo, and shares the Dragon 2 capsule design with Crew Dragon. Dragon 1 was retired after CRS-20 in March 2020.

Cargo Dragon Mission Log

Every cargo Dragon flight, newest first: 35 in all, from the first demonstration flight in 2010 to today's resupply missions. Each mission name links to its launch record. CRS-7 does not appear: it was lost in a launch failure in June 2015, before reaching orbit. Crew flights are in the Crew Dragon mission log.

Frequently Asked Questions

Up to 6,000 kg of pressurised and unpressurised cargo to the ISS, and 3,000 kg of pressurised return cargo: science experiments, biological samples and hardware. The unpressurised trunk can carry external payloads like solar arrays.

Cargo Dragon has flown 35 times, counting the original Dragon 1 and today's Cargo Dragon 2. With Crew Dragon included, Dragon has flown 56 times; the combined count is in the Dragon missions summary.

Yes, this is its unique advantage. All other active ISS cargo vehicles (Cygnus, Progress) burn up on re-entry. Only Cargo Dragon can return significant payloads, making it essential for the ISS science programme.

Yes. Capsules are refurbished and reflown, and the most-flown has made 6 flights. The trunk is expendable. This lowers per-mission costs compared to expendable competitors.

Crew Dragon carries astronauts with life support and a SuperDraco abort system. Cargo Dragon carries supplies only: no life support, no abort engines, no crew displays. Both share the same capsule design and launch on Falcon 9. See the Dragon missions summary for both versions together.

Dragon 1 flew from 2010 to 2020: two demonstration flights, then the CRS-1 to CRS-20 resupply missions, of which CRS-7 was lost in a 2015 launch failure. It was retired after CRS-20 and replaced by Cargo Dragon 2, which carries more cargo and docks autonomously (Dragon 1 was berthed using the ISS robotic arm).
