NASA officials Wednesday announced they have completed a rigorous review of the Space Launch System (SLS) — the heavy-lift, exploration class rocket under development to take humans beyond Earth orbit and to Mars — and approved the program’s progression from formulation to development, something no other exploration class vehicle has achieved since the agency built the space shuttle.
“We are on a journey of scientific and human exploration that leads to Mars,” said NASA Administrator Charles Bolden. “And we’re firmly committed to building the launch vehicle and other supporting systems that will take us on that journey.”
For its first flight test, SLS will be configured for a 70-metric-ton (77-ton) lift capacity and carry an uncrewed Orion spacecraft beyond low-Earth orbit. In its most powerful configuration, SLS will provide an unprecedented lift capability of 130 metric tons (143 tons), which will enable missions even farther into our solar system, including such destinations as an asteroid and Mars.
This decision comes after a thorough review known as Key Decision Point C (KDP-C), which provides a development cost baseline for the 70-metric ton version of the SLS of $7.021 billion from February 2014 through the first launch and a launch readiness schedule based on an initial SLS flight no later than November 2018.
