Cerise (French for "cherry") was a French military reconnaissance satellite. Its main purpose was to intercept HF radio signals for French intelligence services. With a mass of 50 kg, it was launched by an Ariane rocket from Kourou in French Guiana at 17:23 UT, 7 July 1995. Cerise's initial orbital parameters were period 98.1 min, apogee 675 km, perigee 666 km, and inclination 98.0 deg.
It was hit by a catalogued space debris object from an Ariane rocket in 1996, making it the first verified case of an accidental collision between two artificial objects in space.
The collision tore off a 2.8-2.9 metre (9.2-9.5 foot) portion of Cerise's gravity-gradient stabilization boom, which left the satellite severely damaged.
