US based private rocket launching company SpaceX for first time ever has successfully launched used Dragon spacecraft with a used Falcon 9 rocket. The 2 pre-flown rocket parts were launched together for the first time as part of resupply mission to International Space Station (ISS).
The mission was SpaceX’s 13th of 20 under a $1.6 billion contract with National Aeronautics and Space Administration (NASA). After the launch, SpaceX landed its rocket booster upright on solid ground at Cape Canaveral, Florida.
The used Dragon spacecraft was on its way to ISS. It carried 4,800 pounds of supplies for astronauts in ISS. So far, SpaceX has managed to return 20 of its rocket boosters after launch, whether on a floating ocean platform or on land as part of its effort to re-use instead of jettison costly components.
