OSIRIS-REx Gravity Field Estimates for Bennu Using Spacecraft and Natural Particle Tracking Data
The current best estimates of Bennu’s gravity field will be presented, based on the independent solutions from four different teams involved on the OSIRIS-REx mission. The discovery of ejected particles about Bennu that may remain in orbit for several days or more provide a unique opportunity to probe the gravity field to higher degree and order than possible by using conventional spacecraft tracking. However, the non-gravitational forces acting on these particles must also be characterized, and their impact on solution accuracy must be assessed. This talk will present the latest results from the mission, incorporating spacecraft tracking from the lowest orbit in which the satellite will be during the mission.
Improved Impact Hazard Assessment with Existing Radar Sites and a New 70-m Southern Hemisphere Radar Installation
Add radar capability to the existing southern hemisphere 70-m Deep Space Network (DSN) site at Canberra, Australia, thereby increasing by 1.5-2x the observing time available for high-precision NEO trajectory refinement and characterization. Estimated cost: approx.$16 million over 3 years, $2.5 million/year for operations (FY09).
