According to Space Travel.com, the aerospace giant ATK has announced that its planned Liberty Logistics Module or LLM will have an enhanced cargo and crew capability, taking advantage of the lift capacity of planned Liberty Launcher.
The LLM’s enhanced cargo capacity
ATK is claiming that its LLM will be capable of transporting 5,100 pounds of cargo to the International Space Station. That means that the vehicle could take four full-sized science racks to the ISS along with the scientists to perform the experiments. ATK claims that this means that the Liberty system could deliver in one flight what other vehicles in development, such as the SpaceX Dragon or the Boeing CST-100, must deliver in two flights, garnering some cost savings, according to NASA Space Flight. The other options divide their flights into cargo or crew, with different versions of their spacecraft Each flight would take up to seven crew members as well as the cargo.
Liberty launch vehicle derived from Ares 1 design
The Liberty launch vehicle, according to NASA Space Flight, is somewhat derived from the Ares 1, the now cancelled launch vehicle envisioned in the Constellation program. The first stage would consist of a five-segmented solid rocket booster. The second stage would consist of the core stage of the Ariane 5 launcher. According to ATK, the Liberty could take 44,500 pounds of payload to low Earth orbit. The Liberty is a joint venture between ATK and the European aerospace company Astrium.
Test flights scheduled for 2014 and 2015
According to SpaceTravel.com unmanned test flights of the Liberty are scheduled for 2014 and 2015 with the first manned flight to the ISS in late 2015.
Liberty not being funded by NASA
The Liberty did not receive funding under NASA’s commercial crew program, according to NASA Space Flight. The company nevertheless chose to proceed with the development of the launch vehicle and the LLM using its own funds under an unfunded Space Act Agreement with NASA. ATK hopes that the Liberty will be chosen for the next round of funding when NASA is expected to choose two companies to compete for ISS servicing contracts.
Liberty may be gaining favor with NASA
According to NASA Spaceflight, Liberty may be gaining favor with senior NASA managers as an option over those that have received funding under the commercial crew program. Those other options include space vehicles being developed by SpaceX, Boeing, Blue Origin, and Sierra Nevada.
