Reusable orbital rocket

A Falcon 9 first stage returns from an orbital launch and lands upright.

On 21 December 2015 a Falcon 9 booster landed at Cape Canaveral after launching 11 satellites; the first reflight followed in 2017. Reuse cut launch costs sharply, and single boosters have since flown more than 25 times. SpaceX now performs well over 100 launches a year.
