On 30 March, SpaceX made history when it successfully delivered an SES satellite into orbit using a previously flown Falcon 89 first stage booster.
The Falcon 9 has been refurbished since it flew a Dragon capsule to the ISS in April 2016. As well the first stage returning to Earth by vertically landing on its drone ship, in another first company also recovered the nose-cone fairings which soft-landed using parachutes. Musk tweeted of this reusable launcher breakthrough: “Incredibly proud of the SpaceX team for achieving this milestone in space! Next goal is reflight within 24 hours.”
