SpaceX’s latest upgrade aims to make rockets even more reusable

The next launch by Space Exploration Technologies Corp. appears almost routine by now: A  satellite owned by Bangladesh will blast into orbit on top of a reusable Falcon 9 rocket, then the booster will land back on a drone ship to be launched again at a later date. SpaceX has already done this 24 times—11 by land, 13 by sea.
