US Military Aims to Launch Cheap New 'Blackjack' Spy Satellites in 2021

Partner Series Blackjack aims to meet this ambitious cost target by leveraging developments in the private space sector. Several companies plan to establish huge constellations in LEO in the next few years, to deliver cost-effective internet service to people around the globe. SpaceX's Starlink network , for example, will feature thousands of individual satellites. Blackjack will integrate reconnaissance and communications payloads into standard commercial satellite bodies (known as buses) and take advantage of the high launch rate required to loft the mega-constellations, Thomas said. "The Blackjack approach assumes that we're not going to be an anchor tenant. We're not going to be driving these companies," he said during the FISO presentation. "But we want to take advantage of that production line of spacecraft, the buses especially, that they're going to be building. We want to take advantage of that launch and take advantage of all of those pieces." And there are advantages to setting up shop in LEO, just 620 miles (1,000 km) or so above the planet, in addition to the relatively cheap ride. Signal strength is about 1,300 times higher there than it is in geostationary orbit, Thomas said, and communications get down to Earth faster.  It's unclear at the moment which sensors will ride aboard the Blackjack satellites; program officials are currently evaluating payload and spacecraft-bus proposals, which were submitted before a June 6 deadline.
