![]() ![]() "Everything looks good and on schedule for a late '18 launch," he said during the FISO talk. The SLS team has been notching its milestones, including an SRB ground test in June, on time and as expected, DaLee said. SLS is scheduled to make its maiden flight in 2018, when a Block 1 booster will launch an uncrewed Orion on a weeklong trip around the moon known as Exploration Mission-1 (EM-1). Orion has one flight under its belt, an unmanned test to Earth orbit in December 2014 that lifted off atop a United Launch Alliance Delta IV Heavy (which is the most powerful rocket currently in operation). SLS will launch Red Planet pioneers aboard the Orion crew capsule, which is also in development. The rocket is a key part of NASA's plan to get astronauts to Mars, which the agency aims to do before the end of the 2030s. The Block 1B iteration will boost that to 116 tons (105 metric tons), while the Block 2 will max out at 143 tons (130 metric tons) to LEO.īut SLS was not designed with Earth orbit in mind. The first version, known as Block 1, will have a LEO payload capacity of 77 tons (70 metric tons). All of them consist of a core stage, along with two solid rocket boosters (SRBs). SLS is an evolvable vehicle, with three primary variants currently envisioned. "It doesn't tell you exactly the capability." The path to Mars "We're talking about a 130-metric-ton-class vehicle," Robinson said. ![]() She, Sanders, DaLee and Fuller all cautioned, however, that these numbers for SLS are not carved in stone. The "injected mass" capacity of SLS comes out to 173 tons (156.9 metric tons), Robinson added. These three companies are the prime contractors for SLS.) (The FISO talk was given by Chris Sanders of Aerojet Rocketdyne, Bob DaLee of Boeing and Orbital ATK's Mike Fuller. "We have a payload mass to LEO of about 122.4 metric tons for Saturn V," said Robinson, who did not give the FISO presentation but chimed in to answer a question posed by a listener. 3 during a presentation with NASA's Future In-Space Operations (FISO) working group. The SLS team has calculated some apples-to-apples comparisons, and the new rocket comes out on top, Robinson said Aug.
