NASA Unveils SLS Design for Deeper Space Exploration

On Wednesday, NASA unveiled the design of the Space Launch System (SLS) which, when completed, will be able to propel the Orion Multi-Purpose Crew Vehicle far outside the Earths orbit and pave the way for deeper space exploration -- including expeditions to asteroids and Mars. NASA officials are optimistic that the first SLS rocket will be launched in 2017.

The next chapter in Americas space exploration story is being written, right here, right now, said NASA administrator Charles Bolden in a video released on Wednesday. "President Obama challenged us to be bold and dream big, and that's exactly what we are doing at NASA. While I was proud to fly on the space shuttle, kids today can now dream of one day walking on Mars."

Using liquid hydrogen and liquid oxygen, the SLS will be able to lift 70 metric tons when it is first launched. NASA officials are hopeful that the rocket will be able to eventually launch up to 130 metric tons. This flexibility, insisted NASA, was one of the chief strengths of the SLS design which incorporates components of the space shuttle and Constellation programs.

NASA officials also played up the economic impact of the SLS program.

"This launch system will create good-paying American jobs, ensure continued U.S. leadership in space, and inspire millions around the world," Bolden said.
