The United States Missile Defense Agency (MDA) is developing a Space Tracking and Surveillance System (STSS) which it will use to research the space-based detection and tracking of ballistic missiles. Data from STSS satellites could allow interceptors to engage incoming missiles earlier in flight than would be possible with other missile detection systems. The STSS program began in 2001, when the "SBIRS Low" program was transferred to MDA from the United States Air Force.

Famous quotes containing the words space, tracking and/or system:
“When my body leaves me
I’m lonesome for it.
but body
goes away to I don’t know where
and it’s lonesome to drift
above the space it
fills when it’s here.”
—Denise Levertov (b. 1923)
“Such is the art of writing as Dreiser understands it and practices it—an endless piling up of minutiae, an almost ferocious tracking down of ions, electrons and molecules, an unshakable determination to tell it all. One is amazed by the mole-like diligence of the man, and no less by his exasperating disregard for the ease of his readers.”
—H.L. (Henry Lewis)
“While the system of holding people in hostage is as old as the oldest war, a fresher note is introduced when a tyrannic state is at war with its own subjects and may hold any citizen in hostage with no law to restrain it.”
—Vladimir Nabokov (1899–1977)
