SpaceX landed a rocket vertically in the ocean

          Though it’s now the second time SpaceX has landed one of its rockets, Musk’s commercial space company successfully landed the Falcon 9 in the ocean. After four failed attempts throughout the year where the rocket exploded upon its landing, it was beginning to look like SpaceX had finally reached a serious hurdle.

           These ocean landings are harder than a normal ground landing, mostly because it’s a small target, but are much more efficient fuel and cost-wise. In the end, efficiency is really what all these landings are about, since most rockets are either destroyed or lost post-launch as of now. These reusable rockets could end up being the factor that paves the way to affordable commercial space flight.
