Space Show Features Talk on ATK's Liberty Launch Vehicle (Source: Space Show)
Kent Rominger, Program Manager for ATK's Liberty Launch Vehicle was featured in an interview on last week's The Space Show. During our hour long discussion, Mr. Rominger introduced us to the Liberty Launch Vehicle with the European Astrium second stage. We talked about the ITAR issues working with Astrium and spent some time discussing the pros and cons of using a solid rocket booster (SRB) for human spaceflight (HSF) over a liquid rocket motor. Many people in various segments of the space community believe that SRBs are not safe for HSF so we explored this issue in depth with our guest. Click here to listen to the interview. (8/15)

NASA Considers Liquid Rocket Engine for Orion Escape System (Source: Examiner)
NASA’s Langley Research Center is considering using a liquid thruster engine on the next Max Launch Abort System (MLAS) test flight, according to contract documents released on Thursday. MLAS is an alternate astronaut escape system under development at Langley for NASA’s new "Orion" Multi-Purpose Crew Vehicle (MPCV).

The current emergency abort system on MPCV has a single solid rocket engine in a tower positioned above the crew capsule. The alternate MLAS would have four or more solid rocket motors attached. NASA Langley is soliciting information about potential sources for a liquid propellant rocket engine that would be used on MLAS. “The MLAS project is considering incorporating a conventional technology liquid attitude control subsystem for coast flight stabilization and reorientation on Flight Test Vehicle #2,” NASA said.
