Clementine 2 was a proposed asteroid-interception mission that was intended to fly by two near-Earth asteroids, 433 Eros and 4179 Toutatis planned by NASA.[2]

Launch datePlanned:
July 1995
RocketTaurus-1110
Flyby of 433 Eros (proposed)
Closest approach13 March 1996
Distance30 km (19 mi)[2]
Flyby of 4179 Toutatis (proposed)
Closest approach4 October 1996
Distance50 km (31 mi)[2]

The probe impact at Toutatis was needed to obtain the dynamic strength of surface material and data on the properties of the regolith and on stratification below the surface, and potentially allowed the measurement of thermal diffusivity between the interior and the surface. Measurements should be done by high-resolution imagery of the impact crater and its surroundings in visible, ultraviolet, and infrared wave bands from the spacecraft flying by some 30 min after the probe strike. It was proposed to equip the probe with a lightweight mass spectrometer and dust analyzer to measure the particle sizes and distribution and the composition of the eject a cloud. This mission was planned to be launched in Jul 1995, with the Eros encounter on 13 March 1996, and the Toutatis flyby on 4 October 1996, some 440 days after launch.[2]

The mission was a successor of Clementine, and was intended to be launched by Taurus 1110 rocket, but was cancelled in 1997.[1]
