Abstract

The terminal navigation of the Near Earth Asteroid Rendezvous (NEAR) spacecraft during its close flyby of asteroid 253 Mathilde involved coordinated efforts to determine the heliocentric orbits of the spacecraft and Mathilde and then to determine the relative trajectory of the spacecraft with respect to Mathilde. The gravitational perturbation of Mathilde on the passing spacecraft was apparent in the spacecraft tracking data. As a result of the accurate targeting achieved, these data could be used to determine Mathilde's mass as 1.033 (± 0.044) × 10 20 grams. Coupled with a volume estimate provided by the NEAR imaging team, this mass suggests a low bulk density for Mathilde of 1.3 grams per cubic centimeter.

5. The early Mathilde orbits included only 60 observations over the interval 3 May 1927 to 6 January 1994. In January 1995 E. Goffin made available a data set wherein he had re-reduced many of the existing observations with respect to more modern reference star catalogs and extended the observational interval back to the time of this asteroid's discovery in mid-November 1885. Extensive sets of observations were received from a number of observatories including McDonald (Texas) Klet (Czech Republic) Modra (Slovakia) Siding Spring (Australia) Oak Ridge (Massachusetts) the Carlsberg Automatic Meridian Circle (Canary Islands) and the U.S. Naval Observatory Flagstaff Station (Arizona). Some of the observations from Flagstaff were reduced with respect to extragalactic radio sources; these observations were given increased weight in the orbit determination process because they were relatively unaffected by the systematic errors present in most reference star catalogs.
