To fly humans to Mars we will need a very big rocket to lift the hardware needed to live on another planet for several months before heading home. The planned habitat will likely be the same size a two-story house. This means the rocket will be bigger than the mighty Saturn V of the Apollo missions to the Moon.

At SXSW’s trade show, NASA is featuring the SLS rocket that will fit the bill to send people further than ever. Nicholas Case is one of the many engineers working to make sure the SLS is even more successful than the Saturn’s incredible record.
