I nearly forgot about these cancelled missions.
Pre-Dawn: The French-Soviet VESTA mission Very interesting three proposed trajectory for two spacecrafts. Trajectory 1: -launch from Earth -Mars gravity assist -flyby of 2335 James (a 10 km X-type asteroid) (an Amor-asteroid) -Mars gravity assist -109 Felicitas (C-type, 76 km) -739 Mandeville (EMP(?) type, 110 km) -4 Vesta (V-type, or Vestoid. Has a diameter of 570 km) flyby with 3.5 km/s. A penetrator is released. Total delta-v: 450 m/s Trajectory 2: -launch from Earth -Mars gravity assist -flyby of the P/Tritton short period comet -Mars gravity assist -2087 Kochera (30 km?) -1 Ceres (flyby & releasing a penetrator) Total delta-v: 1150 m/s Trajectory 3: -launch from Earth -Mars gravity assist -1204 Renzia (10 km?) (an Amor-asteroid) -Mars gravity assist -435 Ella (U type, 30 km) -46 Hestia (F type, 165 km) -135 Hertha (M type, 80 km) Total delta-v: 350 m/s -------------------- Free software for planetary science (including Cassini Image Viewer).

I noticed the following paragraph in the above article: QUOTE I've heard it's not ruled out that Dawn will be directed to rendezvous with 2 Pallas (for a slow flyby) in 2018, after the main mission at Vesta and Ceres is completed and enough fuel is left. Is that possibly still on the cards? -------------------- |
