First complete orbit is now almost accomplished (Dawn hasn't been using engines in the last 5 days).
During orbit, the speed and distance were constant; such a circular orbit is possible only if we assume that "distance from Vesta" declared in the simulator is measured from asteroid's surface (otherwise, speed should be significantly higher). I updated plots, using an average Vesta radius of 266km and assuming that also final survey orbit height will be 2700 km from surface: Meanwhile, look to last spectacular "family portrait" from simulator: -------------------- I always think before posting! - Marco -
