Other documentation confusingly calls it EM-2, likely in some cheeky way of satisfying politically-driven schedules for SLS to fly “EM-2” by a certain date. The new EUSU was an in-house design by NASA Engineering and is being fabricated by JP Donovan. However, like ML-1, that cost is likely to rise over time based on the challenges involving ML-1, which ranged from being overweight to suffering from a slight lean. See AlsoSLS Forum SectionL2 SLS SectionClick here to Join L2. The team has joined with four subcontractors to jointly ensure the success of getting “Boots on the moon in 2024.”. “While these tasks have been rehearsed individually, the return to Pad 39B allows the team to perform this sequence altogether,” said Charlie Blackwell-Thompson, Artemis launch director. The decision to keep SLS in its Block 1 configuration and launching off ML-1 deep into the 2020s now leaves NASA with some decision points. With the crewed EM-1 plan rejected, managers then looked into bringing the more powerful Block 1B rocket online sooner, as early as EM-2. Lanham said this is an added safety measure, in addition to the walk downs performed prior to launch. A second Mobile Launcher (ML-2) for NASA’s Space Launch System (SLS) is heading into its construction phase as Ground Support Equipment begins to arrive at the Kennedy Space Center (KSC). But the effort will require a massive, new rocket and the infrastructure to safely assemble and launch it from. Selected in 2019, Bechtel will design, build, test, and commission ML2: a ground structure used to assemble and launch the Space Launch System (SLS) Rocket and Orion spacecraft from Launch Pad 39B at Kennedy Space Center. A series of missions will include a flight around the moon, a landing, and a moon-orbiting space station. NASA is committed to landing the first woman and the next man on the moon by 2024 as part of the Artemis program. A brand-new Falcon Heavy for a high priority science mission would cost just over $100 million, whereas the latest estimates for SLS put the per-mission cost anywhere between $500 million (from NASA in 2013) to a range between $1.5 – $2.5 billion (conservative industry estimates in December 2017). Working with U.S. companies and international partners like Bechtel, NASA will push the boundaries of human exploration. (NASA photograph by Ben Smegelsky) SLS could one … There is currently a mobile launcher in existence at KSC that will support the first two launches for the Artemis program that sends American astronauts back to the moon. However, with ML-1 in the VAB, the construction site north of the assembly building has been freed to allow for the build-up of the huge structure to begin in earnest. Bechtel is teaming with industry leaders as we execute the ML2 project. The plan, up until this year, had been to modify this ML for the Block 1B SLS after the uncrewed EM-1 test flight. It too will undergo testing at the LETF before being delivered for integration onto the ML-2 tower. The procurement will go in a two-step process, starting with a … Bechtel National Inc., of Reston, Virginia will design, build, test and commission the mobile launcher during a 44-month period beginning July 1. Cimarron also is contributing expertise in systems engineering, configuration and data management, mission assurance and reliability, as well as human factor analysis. The ML2 structure will be used to assemble and process NASA’s SLS Block 1B rocket and Orion spacecraft inside of the Vehicle Assembly Building. The facility allows for simulated launch vehicle events such as movement from wind, ignition and liftoff, effects of solar heating and cryogenic shrinkage. The initial money will be used to pay for a civil engineering outfit to design ML-2 and provide funds to build its basic structure. The cost-plus-award-fee contract carries an estimated value of approximately $402 million with a term of 47 months. Bechtel Corporation. NASA called for a second ML to be constructed to cater for the slightly taller Block 1B SLS that is set to come online in the middle of the decade. During its two-week stay at the pad, engineers will perform several tasks, including a timing test to validate the launch team’s countdown timeline, and a thorough, top-to-bottom wash down of the mobile launcher to remove any debris remaining from construction and installation of the umbilical arms. In May 2019, NASA announced the Artemis program with the goal to return U.S. astronauts to the Moon by 2024 using the Space Launch System (SLS), the Agency’s new heavy-lift rocket. The Gateway is now firmly in NASA’s roadmap and continues to pass the approval stages within the U.S. government. The mobile launcher for Artemis I begins rollout from the Vehicle Assembly Building atop crawler-transporter 2 in the early morning on Oct. 20, 2020, at NASA's Kennedy Space Center in Florida.

Initially, this was set to occur after two test flights – one uncrewed, one crewed – with the Block 1. It is understood that ML-1 would be converted to provide SLS Block 1B with cargo-only mission capabilities. With the goal to return humans to the moon by 2024, NASA announced Tuesday the plans to design and build a second mobile launcher, known as Mobile Launcher 2 or ML2, at Kennedy Space Center. Intended specifically for NASA's Space Launch System Block 1B rocket, which will carry the Orion spacecraft and Exploration Upper Stage, ML2 will launch the rocket intended to send humans back to the lunar surface from KSC pad 39B. “During the Artemis launch countdown, this work will be performed prior to tanking,” Blackwell-Thompson said. Space Launch System (SLS) managers are now planning for the utilization of two Mobile Launchers (MLs), allowing for additional use of the rocket on both crewed and cargo-only missions. The cost-plus-award-fee contract carries an estimated value of approximately $402 million with a term of 47 months. NASA designed the SLS as the world’s most powerful rocket for safely sending humans on missions to deep space, and Orion is specifically designed to keep humans alive hundreds of thousands of miles from home. Artemis I will test the Orion spacecraft and SLS as an integrated system ahead of crewed flights to the Moon. © 2020 www.floridatoday.com. After successfully arriving at Kennedy Space Center’s Launch Complex 39B, Exploration Ground Systems' mobile launcher is photographed at the pad surface atop the crawler-transporter 2 on June 28, 2019. Subsequent design iterations for the Block 1B tower have changed the EUS umbilicals and added a Vertical Stabilizer Damper above. The publisher assumes no responsibility for error in ads other than space used. The contract is likely to hit the streets this Summer, prior to being awarded to the winning contractor next year.
