SpaceX have performed a successful launch and landing of their new Falcon 9 rocket, launching from Cape Canaveral, Florida and then landing on a drone ship in the Atlantic Ocean.
The new model Block-5 version of the rocket sent a communication satellite into orbit for Bangladesh.
The Block-5 version of the rocket features around 100 upgrades over the previous model, and is designed to be a more re-usable rocket, capable of 10 or more flights without substantial refurbishment being required.
Re-usability of rockets is one of the major cost barriers to spaceflight, and creating highly re-usable rockets is a core goal for SpaceX and its owner Elon Musk.
Mr Musk said in a pre-lunch press conference that ideally the rockets will be immediately re-usable after having a new upper stage and nose cone refit and refuelling following landing.
He added that with moderate maintenance the rockets could potentially fly up to 100 times each.
But for this particular rocket, a post flight break-down needs to occur to make sure everything has worked as intended.
“Ironically, we need to take it apart to confirm that it does not need to be taken apart,” Mr Musk said.
