We need to get to the moon by 2024. Will this rocket be able to take us there? - Chron

Two boosters will be attached to NASA's Space Launch System rocket that will carry astronauts to the moon.

The Space Launch System (SLS) is supposed to be for NASA today what the Saturn V was for the space agency in the '60s and '70s: the workhorse.

NASA used the Saturn V to launch 12 out of the 15 Apollo missions, including all those that took astronauts to the Moon.

With its first mission scheduled to launch only this fall, NASA was at first indecisive about whether it should perform another test and risk delay.
