ScienceDaily (May 12, 2012) NASA's Space Launch System is on track to give America the launch vehicle it will need to send humans deeper into space than ever before, the program's manager said May 8. <\/p>\n
Speaking to the National Space Club during a luncheon near NASA's Kennedy Space Center in Florida, Todd May, SLS program manager, said an uncrewed test flight of the Orion spacecraft in 2014, SLS mission in 2017 and a 10- to 14-day mission with astronauts going to the moon and back in 2021 will leave the nation in a position to explore as far as it wishes. <\/p>\n
\"By that point, you'll have the capability to go anywhere in the solar system people want to go,\" May said. May leads a team of engineers and designers at NASA's Marshall Spaceflight Center in Huntsville, Ala. \"The ultimate goal is to put human boots on Mars.\" <\/p>\n
Kennedy designers also are at work to make a place for the SLS to be assembled and launched from. Launch Pad 39B has seen significant changes and the Vehicle Assembly Building is undergoing modernizations to host the 36-story-tall SLS. Also, the mobile launcher that will hold the rocket and its servicing connections already has conducted a test at the pad. <\/p>\n
A test version of the Orion capsule is inside the Operations and Checkout Building at Kennedy and the spacecraft that will make the first test flight into space is expected in a couple of months. It will undergo final assembly at Kennedy before being mounted atop a Delta IV rocket for a mission without astronauts aboard to test the spacecraft's systems and heat shield. <\/p>\n
There's a lot going on,\" said Scott Colloredo, chief architect of the Ground Systems Development and Operations Program. \"Whenever you see hardware moving in the direction of the launch pad, that's always significant.\" <\/p>\n
Many elements of the SLS itself already are in testing, including the engines and solid rocket boosters that will give the rocket about 8 million pounds of thrust at launch, 10 percent more than the Saturn V. <\/p>\n
NASA already has an inventory of space shuttle main engines that will be used to power the core stage. \"The propulsion elements are in really good shape,\" May said. \"Sixteen space shuttle main engines, that's a good head start.\" <\/p>\n
The SLS also will use solid rocket boosters like the shuttle, but the SLS versions will be five segments instead of four. <\/p>\n
The core stage, which will hold the fuel tanks for the main engines, is early in its design but still is on schedule. Like the space shuttle external tanks, the core stage will be built at NASA's Michoud Assembly Facility in Louisiana. The SLS stage is about 15 feet longer than the shuttle's external tank, and it will be shipped to Kennedy on the Pegasus barge, another element shared with the shuttle. <\/p>\n<\/p>\n
