Space-X lands a rocket booster, on land

The video is fascinating, a big rocket hovering on engine power and carefully backing down to the ground.  Landing upright, all in one piece.  Space-X hopes to lower the cost of spaceflight by soft landing and reusing the booster.   Amusingly, the Fox News commentator keep referring to the rocket engines as "afterburners".  Sorry Fox, an afterburner is a power boosting device applied to jet engines, not rockets.  Afterburners can double your thrust, at the cost of horrible fuel consumption.  Only military fighter planes are equipped with afterburners due to their ability to suck down fuel like a sewer pipe.  To call the rocket engines of a booster afterburners reveals the depth of ignorance of the newsies.
