![]() "It's our job to comply with their requirements. NASA currently manages SLS production, with Boeing and Northrop its top contractors, each having contracts under which the space agency bears any delay costs. ![]() That repair may prevent another leak.Įngineers will have to perform the fix directly on the launch pad, though the agency said it may have to roll the SLS back to the Vehicle Assembly Building to perform additional checks and to reset the system's batteries before it is launched.įree, however, said NASA has sought a waiver from Space Force so it can launch in late September. A lack of SLS launch dates amid a backlog of Artemis program missions in the coming years is another roadblock, even if there is demand for the rocket beyond NASA, Chaplain said. Before the SLS flies, NASA will have replaced the seal on an interface called the quick disconnect that's used to pump liquid hydrogen fuel into the rocket via a feed line from the mobile launch tower. Hydrogen leaks have continued to plague the SLS, becoming apparent even in dry test rehearsals. NASA sees our space future as both government and privately run.NASA picks a tailor for Artemis moonwalking suits.NASA scrubs Artemis mission yet again because SLS just can't handle the pressure.NASA's Artemis rocket makers explain that it's a marathon and a sprint.Heat will cause the liquid to expand, and liquid hydrogen is prone to seeping out from tiny pores or seams. The gases have to be pressurized and maintained at cryogenic temperatures to, among other things, prevent them from evaporating. Although they make for powerful and light fuels, the substances are difficult to contain. With its unprecedented power and capabilities, SLS is the only rocket that can send Orion, astronauts, and cargo directly to the Moon on a single mission. Using liquid oxygen and hydrogen to put many tons of machinery into space is risky. NASA’s Space Launch System, or SLS, is a super heavy-lift launch vehicle that provides the foundation for human exploration beyond Earth’s orbit.
