November 5, 2010 - Vandenberg Air Force Base. There was a sentimental blastoff from California on Friday night as the venerable Delta 2 made its one-and-only flight of the year, chalking up a major milestone for the rocket family's lasting legacy while also finishing deployment of Italy's radar satellite quartet that images the world for peace and security. Launching at 7:20 pm from Vandenberg Air Force Base, the space booster that has defined dependability for two decades successfully shot the COSMO-SkyMed 4 craft into orbit. It's the last commercial mission currently booked for the Delta 2 rocket, which faces an uncertain future in the years ahead. Three launches carrying satellites for NASA will occur in 2011, but whether the program flies beyond next year depends whether five additional vehicles in inventory can be sold.
