The giant rocket NASA is building to carry astronauts to Mars and other destinations in deep space may cost $500 million per launch when it's flying regularly, space agency officials said Tuesday (Sept. 11). <\/p>\n
NASA is eyeing $500 million as a target right now for the Space Launch System (SLS) when it begins making roughly one flight per year, which could begin happening after 2023. But things could change as the SLS program which was just announced in September 2011 matures, officials said. <\/p>\n
\"We've estimated somewhere around the $500 million number is what an average cost per flight is,\" SLS deputy project manager Jody Singer, of NASA's Marshall Space Flight Center in Huntsville, Ala., said Tuesday during a presentation at the American Institute of Aeronautics and Astronautics SPACE 2012 conference in Pasadena, Calif. <\/p>\n
\"But again, I'd caution you, because we still are working on our contracts and where we're going,\" Singer added. \"Plus we're in the development phase, and you really have to have a little bit more of a steady-state flight launch to be able to get the more efficient launch rate. But that's the number we're using right now.\" [Photos: NASA's Space Launch System] <\/p>\n
NASA's next big rocket <\/p>\n
NASA unveiled the SLS just two months after the last flight of its venerable space shuttle program, which was grounded in July 2011 after 30 years of orbital service. <\/p>\n
But the giant rocket and the capsule it will loft known as the Orion Multi-Purpose Crew Vehicle are not a replacement for the space shuttle. That space-taxi role will be filled by private American spaceships, which NASA is grooming to be ready to carry astronauts to and from low-Earth orbit by 2017. <\/p>\n
The SLS-Orion combo, on the other hand, is a deep space transportation system. In 2010, President Barack Obama charged NASA with getting astronauts to a near-Earth asteroid by 2025 and then on to the vicinity of Mars by the mid-2030s, and SLS-Orion is how NASA will try to make that happen. <\/p>\n
The first test flight of the SLS is slated for 2017, and NASA hopes the rocket will begin lofting astronauts in 2021. <\/p>\n
If the SLS is able to meet the $500 million target, it would end up being cheaper to fly than the space shuttle. The shuttle program cost about $209 billion (in 2010 dollars) over its lifetime and made a total of 135 flights, yielding an average cost per launch of more than $1.5 billion. <\/p>\n<\/p>\n
