Liberty System Includes Spacecraft, Launch Vehicle, Ground and Mission Ops
ATK announced today it has developed its Liberty concept into a complete commercial crew transportation system, including the spacecraft, abort system, launch vehicle, and ground and mission operations, designed from inception to meet NASA’s human-rating requirements with a potential for the first test flight in 2014 and Liberty crewed flight in 2015. The company also announced Lockheed Martin will provide support to the ATK and Astrium Liberty team as a major subcontractor on the project.
“Our goal in providing Liberty is to build the safest and most robust system that provides the shortest time to operation using tested and proven human-rated components,” said Kent Rominger, vice president and program manager for Liberty. “Liberty will give the U.S. a new launch capability with a robust business case and a schedule that we expect will have us flying crews in just three years, ending our dependence on Russia.”
“Liberty will enable a successful commercial space program and result in a globally competitive capability that America doesn’t have today,” said Rominger. “This program is changing the way we do business and can also result in a positive change to government programs.”
Liberty's test flights are expected to begin in 2014, with a crewed mission anticipated in late 2015. The current schedule will support crewed missions for NASA and other potential customers by 2016, with a price-per-seat that is projected to be lower than the cost on the Russian Soyuz rocket. Liberty’s approach is to bring together flight-proven elements designed from inception to meet NASA’s human-rating requirement, reducing development time and costs, and providing known, reliable and safe systems. The simple configuration of a solid first stage and liquid second stage lowers the likelihood of failure and enables a flight path with total abort coverage, maximizing survival for the crew in the unlikely event of an anomaly requiring an abort. In addition, the Liberty spacecraft leverages design work performed at NASA Langley Research Center on the composite crew module and launch abort system, for which ATK was a contractor.
“Because Liberty provides a safe and reliable vehicle for the crew, as well as a sustainable business for years to come, it can be a successful commercial business,” said Rominger. “Liberty’s business case benefits from mature, flight-proven elements that dramatically lower our up-front development costs.” Liberty’s performance of 44,500 pounds to low-earth orbit enables the system to launch both crew and cargo and also serve non-crewed markets including ISS cargo up and down mass, commercial space station servicing, U.S. government satellite launch, and future endeavors.
“We believe that no other offering can match Liberty’s safety, spacious spacecraft, customer service and performance,” said Rominger. “These traits enable the Liberty business to provide the best commercial space flight experience.” The Liberty spacecraft includes a composite crew module, which ATK built at its Iuka, Miss., facility as part of a NASA risk-reduction program at Langley between 2007 and 2010. As prime contractor, ATK is responsible for the composite crew module, Max Launch Abort System (MLAS), first stage, system integration and ground and mission operations, while Astrium provides the second stage powered by the Vulcain 2 engine and Lockheed Martin provides subsystems and other support.
“Astrium is proud to be part of the ATK Liberty team and to provide our proven second stage, which is powered by the Vulcain 2 engine, as an integral part of this exciting next-generation launch system,” said John Schumacher, CEO of Astrium in North America, an EADS North America company. “Initially, we will ship the second stage to the Kennedy Space Center where it will be integrated by the skilled workforce there. However, once Liberty’s business base is established in the U.S. market, we envisage Liberty upper stage manufacturing in the United States.”
Lockheed Martin is providing crew interface systems design, subsystem selection, assembly, integration and mission operations support for the Liberty spacecraft. These subsystems could include avionics, guidance navigation and control, propulsion systems, environmental control system, docking system and other components. “Combining Lockheed Martin’s and ATK’s decades of human spaceflight experience to create the Liberty space vehicle will help ensure America’s crew access to the International Space Station – sooner rather than later,” said Scott Norris, Lockheed Martin Lead, Liberty Program. “We look forward to our role supporting Liberty as it delivers on a highly-effective cost solution for NASA crew and for commercial missions.”
The program has optimized and streamlined development, fabrication and mission operations while ensuring the utmost safety to support a commercial marketplace. Liberty also builds upon processes from existing ATK, Astrium and Lockheed Martin commercial programs. ATK’s commercial programs include solid rocket motors for various launch vehicles, system integration and composite technology (for crew module, Delta IV, Atlas V and A350 Airbus composite structures) and other commercial products. Astrium builds the Ariane 5, which launches the majority of the world’s commercial satellites and is afforded the lowest insurance rates based on its successful track record. Lockheed Martin commercial programs include satellites, the Atlas V and Athena launch vehicles.
“The team’s combined best practices enable Liberty to offer affordable access to space, both to serve existing market needs and, critically, to spur the development of new markets that depend on affordable, safe access to space,” said Rominger.
Liberty has been developed under a CCDEV-2 unfunded Space Act Agreement (SAA) with the NASA Commercial program office at the Kennedy Space Center. All development to date has been performed on internal funding from ATK and Astrium. Under this SAA, the team has successfully completed four milestones. The next major milestone is a structural test of the second stage tank, to be conducted at Astrium in June. “Working with the NASA team under the SAA has provided significant benefit to the development of the Liberty crew transportation system,” said Rominger.
