Dragon became the first commercially-built and operated spacecraft to be recovered successfully from orbit.It was launched on 22 May 2012 from Florida  and on 25 May 2012, an uncrewed variant of Dragon became the first commercial spacecraft to successfully rendezvous with the International Space Station (ISS) and now it has come down to Earth on 2 June 2012 successfully.The capsule was loaded with 1,100 pounds of food, water, clothing and equipment for ISS. 

Dragon Highlights:

1. Fully autonomous rendezvous and docking with manual override capability 
    in crewed configuration.
2.  6,000 kg (13,228 lbs) payload up-mass to LEO; 3,000 kg (6,614 lbs)    
    payload down-mass.
3. Payload Volume: 10 m3 (350 ft3) pressurized, 14 m3  (490 ft3)    
    unpressurized.
4. Dragon is 4.4 meters (14.4 feet) tall and 3.66 meters (12 feet) in diameter.
5. The trunk is 2.8 meters (9.2 feet) tall and 3.66 meters (12 feet) wide. With 
    the solar panels fully extended, the vehicle measures 16.5 meters (54 feet)    
    wide.
6. Supports up to 7 passengers in Crew configuration.

Transporting Crew and Cargo:

To ensure the rapid and secure transportation of Crew and Cargo to ISS, dragon has the same configuration with the exception of the crew escape system, life support system and on board control that allows crew to take control of capsule when needed.For cargo launches the inside of the spacecraft is outfitted with a modular cargo rack system designed to accommodate pressurized cargo in standard sizes and form factors.For crewed launches, the interior is outfitted with crew couches, controls with manual override capability and upgraded life-support.   


Re-Entry:

1. Designed for water landing under parachute for ocean recovery.
2. Designed for lift during reentry for precise landing and low g-forces.
