Abstract The Navigation Ancillary Information Facility (NAIF) at Caltech’s Jet Propulsion Laboratory, acting under the directions of NASA’s Office of Space Science, has built a data system-named SPICE-to assist scientists in planning and interpreting scientific observations. SPICE provides geometric ...
Abstract The NASA MESSENGER mission explored the innermost planet of the solar system and obtained a rich data set of range measurements for the determination of Mercury’s ephemeris. Here we use these precise data collected over 7 years to estimate parameters related to general relativity and the...
