In 2002 on this date, NASA’s CONTOUR probe launched from Cape Canaveral. CONTOUR was a five-year mission to explore three comets, using repeated encounters with Earth to modify its orbit in order to reach each target. Unfortunately, during a main engine burn in orbit, CONTOUR disappeared, likely destroyed. Learn more at NASA’s CONTOUR page here.
