This month’s presentation will highlight the successful Orbital Express (OE) mission. Dr David Kaufman, OE NextSat Program Manager, will speak about the design, development and mission operations of the mission and future implications for on-orbit on orbit servicing of spacecraft. spacecraft Orbital Express was a space mission managed by DARPA. The Orbital Express program was aimed at developing a safe and cost-effective approach to autonomously service satellites in orbit. The system consisted of two spacecraft: the Autonomous Space Transport Robotic Operations (ASTRO) vehicle, built by prime contractor Boeing, and a prototype modular next-generation serviceable satellite (NextSat) built by Ball Aerospace & Technologies Corp. The mission launched from Cape Canaveral on March 8, 8 2007, 2007 aboard an Atlas V. V ASTRO successfully docked with NextSat multiple times from separations of up to 400 km and demonstrated refueling and replacement of a flight component module in orbit. Dr. David Kaufman has been at Ball Aerospace since 2000. He worked on the OE program from its inception and became Program Manager in 2004. He is currently the program manager for STP-SIV, a small space vehicle with a standard payload interface designed to host a variety DoD space experiments in a range of LEO orbits without the need for design changes to the standard bus. David started his aerospace career as a Thermal Engineer in 1994 at Hughes Space and Communications Co. in El Segundo, CA where he had lead roles on the GOES N-Q proposal, DirecTV 1-R, Astra 2C, Superbird-4, and multiple other geosynchronous communications satellite programs. He was the PI on several IR&D projects and holds a patent for a compact RF plasma generator. g from the California Institute of Dr Kaufman holds Ph.D. and M.S. degrees Technology in Mechanical Engineering specializing in plasma engineering and Bachelors degrees from Stanford and Willamette Universities.

n NEW AND NOTABLE 2 for 2 The Orbital Express system successfully completed its on-orbit satellite-servicing demonstrations this summer. Here, OE’s NextSat satellite is seen in a photo taken by the Boeing-built Autonomous Space Transport Robotic Operations (ASTRO) spacecraft of OE. ASTRO was approaching to perform a soft capture. . Tech demo spacecraft achieve objectives By Marc Sklar SERVICE STATION IN SPACE OE is made up of two vehicles, the Boeing-built Autonomous Space Transport Robotic Operations (ASTRO) and NextSat, a spacecraft developed by Ball Aerospace. ASTRO acted like a combination service station and repair truck, working on NextSat. NextSat was built to demonstrate a satellite with components that could be replaced and the capability to be refueled while on orbit. OE, sponsored and led by the Defense Advanced Research Projects Agency, demonstrated a variety of on-orbit firsts, including • Capturing and servicing a satellite without help from the target satellite. • Using onboard navigation and guidance to approach and station-keep (hold position) within 10 centimeters (4 inches) of another satellite. • Using an IEEE 1394–standard high-speed data connection—known on personal computers as a FireWire connection—that allowed ASTRO to remove and replace its own sensor computer. • Transferring propellant from one space vehicle to another using U.S.-built technology. 10 Boeing image courtesy of Defense Advanced Research Projects Agency T he cost of a satellite designed to orbit as far as 23,000 miles (37,000 kilometers) in space can run in the hundreds of millions of dollars. No wonder owners and builders are always looking for ways to increase the capabilities and extend the lives of these modern marvels. Two Advanced Systems technology demonstration successes, the Orbital Express (OE) and CubeSat TestBed1 (CSTB1), could help Boeing deliver on all of the above for satellite customers. Advanced Systems is the Integrated Defense Systems group responsible for developing new technologies and products for IDS businesses, including Space and Intelligence Systems, the IDS satellite business. Over the spring and summer, OE and CSTB1 completed all of their primary mission objectives. • Capturing a free-flying space vehicle and transferring components using an autonomously operated robotic arm with its own onboard video sensors, and with the ability to correct for errors without outside inputs. powerful picosatellite Meanwhile, CSTB1 is a picosatellite (satellite weighing less than 2.2 pounds or 1 kilogram) used for a variety of technology demonstrations. CSTB1 is evaluating technologies, design elements, and attitude (orientation) determination and control approaches for future operational nanosatellites (satellites weighing less than 22 pounds or 10 kilograms). “Both of these programs have shown potential applications that could add value and/or cut costs for Boeing’s satellite cus- tomers,” said Alex Lopez, vice president, Advanced Network and Space Systems. “Orbital Express offers the possibility of replacing a failed component or replenishing fuel rather than writing off an on-orbit satellite that is otherwise healthy and functioning.” Lopez noted that design elements evaluated by CSTB1 can be incorporated into larger spacecraft. That could reduce volume, mass and power needs for the main spacecraft bus (the core physical and electrical structure of a satellite) and increase resources available for mission and payload needs. So, when communications companies, governments and other satellite buyers go shopping in the future, this summer’s twin test successes could make Boeing an even better place to buy. n marc.a.sklar@boeing.com October 2007 BOEING FRONTIERS
