\f0\fs24 \cf0 SpaceX rocket recycling\
\
When SpaceX next launches a cargo mission to the International Space Station, it will try to land and reuse the first stage of its Falcon 9 rocket rather than allowing it to fall to Earth and be destroyed\
----------------------------------------\
Second stage (with Dragon capsule): Can carry six tonnes of cargo into space and return three tonnes to Earth\
\
Hypersonic grid fins (x4): Unfold during descent to aid stability\
\
First stage:Incorporates nine Merlin engines \'96 fuelled by liquid oxygen and kerosene \'96 able to produce up to 1.5 million pounds of thrust\
\
Landing legs:Fold down to stabilise rocket on barge\
\
Landing barge: Unmanned and size of football field. Not anchored but powerful thrusters keep it in place\

First stage: Rocket must slow from nearly 5,800km/h to zero, and not miss barge. Odds of success said to be 50% at best\
