SpaceX to try to recover rocket's upper stages using balloon
Founder Elon Musk has claimed that SpaceX will try to recover rocket's upper stages out of orbital velocity using a "giant party balloon". Calling the idea "crazy", Musk further said the rocket stage will "then land on a bouncy house." Currently, SpaceX estimates a cost of $62 million for a Falcon 9 rocket launch including the first stage recovery.
