University of California, Berkeley- launched in 2002 Active Cavity Radiometer Irradiance Monitor Satellite (ACRIMSAT) for NASA/ JPL- launched in 1999 Planetary exploration Orbital's heritage Planetary Exploration Heliophysics satellites are as listed below: Dawn for NASA/ JPL- launched in 2007 Deep Space 1 for NASA/ JPL- launched in 1998 National security systems Orbital's national security systems range from smaller, more affordable spacecraft buses (e.g. disaggregated systems) to hosted payload applications. Orbital advocates disaggregated systems because conceptually disaggregated systems can lower the cost and accelerate the development and deployment of national security space systems. For example, Orbital's GEOStar-1 spacecraft provides a compact platform optimized for GEO missions (adaptable for MEO for launch aboard Minotaur, Falcon, and EELV launch vehicles to deliver resilient capabilities in a relatively short period of time (years instead of decades). Orbital's hosted payload capabilities in national security systems include the Hosted Infrared Payload (CHIRP) program for the U.S. Air Force. The wide-field of view sensor was hosted on an Orbital-built commercial GEO communications satellite. Orbital's hosted payload program takes advantage of the high frequency of commercial satellite launches and the excess resources that typically exist on a commercial communications satellite to provide frequent and low-cost access to space for National Security Systems. Advanced flight systems Orbital's current advanced flight systems programs include the contract with Stratolaunch Systems to design a new intermediate-class rocket to be carried aloft and launched from the largest aircraft ever built-Stratolaunch carrier aircraft. Orbital is responsible for the program's overall systems engineering, and the development, production, test, and operations of the air-launch rocket and related ground operations, including payload and launch vehicle integration. A demo launch is currently scheduled for 2017. Orbital's heritage programs in advanced flight systems include the NASA X-34 and X-43 programs, and the Orion Launch Abort System, among others.
