Space Launch System
The
Space Launch System
(
SLS
) is an American
Space Shuttle-derived
heavy
expendable launch vehicle
being designed by
NASA
. It follows the cancellation of the
Constellation program
, and is to replace the retired
Space Shuttle
. The
NASA Authorization Act of 2010
envisions the transformation of the Constellation program's
Ares I
and
Ares V
vehicle designs into a single launch vehicle usable for both crew and cargo, similar to the
Ares IV
. SLS will be the world's most powerful rocket with about 20% more thrust than
Saturn V
and a comparable payload capacity.
