Program Overview
The Cargo Dragon program, operated by SpaceX under NASA’s Commercial Resupply Services (CRS) contract, is a series of uncrewed cargo missions to the International Space Station (ISS). Based on the Dragon spacecraft platform, the program began in 2012 and became a key component of ISS logistics, delivering pressurized and unpressurized cargo, science experiments, hardware, and crew supplies. It is the first commercial cargo vehicle capable of returning significant amounts of payload safely to Earth.

Objectives
The main goals of the Cargo Dragon program include:

  • Transporting scientific experiments, crew supplies, and station hardware to and from the ISS.
  • Supporting microgravity research in biology, physics, and materials science.
  • Returning time-sensitive cargo and completed experiments to Earth via ocean splashdown recovery.
  • Demonstrating cost-effective, commercial delivery capabilities to low-Earth orbit.

Key Details
- Manufacturer: SpaceX
- Variants: Dragon 1 (CRS-1 to CRS-20), Dragon 2 (CRS-21 onward)
- Launch Vehicle: Falcon 9
- Launch Site: Kennedy Space Center and Cape Canaveral Space Force Station
- Recovery: Splashdown in the Atlantic Ocean (Dragon 1) or Gulf of Mexico (Dragon 2)
- First Launch: May 22, 2012 (Dragon C2+)
- First Operational Mission: October 8, 2012 (CRS-1)
- Reusable: Yes (capsule and trunk for Dragon 2; capsule only for Dragon 1)

Structure
Cargo Dragon consists of a pressurized capsule for sensitive and recoverable payloads, and an unpressurized "trunk" used for larger hardware, solar arrays, and external payloads. The capsule contains avionics, propulsion, thermal control, and a parachute system for Earth return. Dragon 2 improved upon Dragon 1 with enhanced automation, greater cargo volume, and faster refurbishment turnaround.

Mission Profile
Cargo Dragon launches atop a Falcon 9 rocket, separates in orbit, and uses onboard thrusters to rendezvous with the ISS. It is captured by the station's robotic arm (Dragon 1) or docks autonomously (Dragon 2) and remains berthed for several weeks while cargo is transferred. Upon departure, the capsule reenters Earth's atmosphere and splashes down for recovery and cargo return.

Achievements
The Cargo Dragon program was the first commercial spacecraft to deliver and return cargo from the ISS. It demonstrated reliable, reusable logistics support and contributed to a new model of public-private partnership in space. Dragon 2 continues to deliver vital science and supplies, supporting the transition to sustainable human spaceflight operations.
