Preventing a Space Pearl Harbor: SBSS Program to Monitor the Heavens
Defense Industry Daily

In January 2001, a commission headed by then US Defense Secretary-designate Donald Rumsfeld warned about a possible “space Pearl Harbor” in which a potential enemy would launch a surprise attack against US-based military space assets, disabling them. These assets include communications satellites and the GPS system, which is crucial for precision attack missiles and a host of military systems.
“The US is more dependent on space than any other nation. Yet the threat to the US and its allies in and from space does not command the attention it merits,” the commission warned.
One of the systems that grew out of the commission’s report was the Space Based Space Surveillance (SBSS) project, which is developing a constellation of satellites to provide the US military with space situational awareness using visible sensors. …
The SBSS system is intended to detect and track space objects, such as satellites, anti-satellite (ASAT) weapons, and orbital debris, providing information to the US Department of Defense as well as NASA. The SBSS is a stepping stone toward a functional space-based space surveillance constellation. …
The initial SBSS satellite is expected to improve the US government’s ability to detect deep space objects by 80% over the MSX/SBV system.
The MSX/SBV system was a late 1990s missile defense test satellite; by 2002 most of its sensors had failed. However, 1 small package called the SBV sensor was able to search and track satellites in geosynchronous orbit (GEO) using visible light. …
Building on the success of the MSX/SBV visible sensor, the SBSS Block 10 will further develop the technology and replace the SBV sensor. Block 10 will involve the development of 1 satellite as a pathfinder for a full-constellation of space-based sensors. …
Jan 15, 2010: Boeing in Seal Beach, CA received a $30.9 million contract exercising the option for CY2010 maintenance and operations services to provide the requirements for the development and delivery of the logistics infrastructure of the Space Based Space Surveillance Block 10 system. At this time, $7.8 million has been obligated.
