Near Earth Asteroid Rendezvous (NEAR) Revised Eros Orbit Phase Trajectory Design
Trajectory design of the orbit phase of the NEAR mission involves a new process that departs significantly from those procedures used in previous missions. In most cases, a precise spacecraft ephemeris is designed well in advance of arrival at the target body.
A Comprehensive Orbit Reconstruction for the Galileo Prime Mission in the J2000 System
The Galileo spacecraft arrived at Jupiter in December of 1995 to begin an orbital tour of the Jovian system. The objective of the tour was the up close study of the planet, its satellites, and its magnetosphere.

Estimating the Mass of Asteroid 433 Eros During the Near Spacecraft Flyby
The terminal navigation of the Near-Earth Asteroid Rendezvous (NEAR) spacecraft during its flyby of asteroid 433 Eros on December 23, 1998 involved coordinated efforts to determine the heliocentric orbits of the spacecraft and Eros and then to determine the relative trajectory of the spacecraft with respect ot Eros.
Navigating Galileo in the Jovian System
The Galileo spacecraft's navigation results for the first eleve Jupiter satellite encounters are described.
Preliminary Considerations for NEAR's Low-altitude Passes and Landing Operations at 433 Eros
NASA's Near Earth Asteroid Rendezous (NEAR) mission is currently on course for rendezous and orbit insertion about the asteroid 433 Eros in December 1998.
Investigations into the Unexpected Delta-V Increases during the Earth Gravity Assists of Galileo and NEAR
This paper will further investigate the possible resources of these anomalous delta-V's beyond the work of Kallemeyn.
Galileo Orbit Determination for the Earth-1 Encounter
The galileo spacecraft was launched on October 18, 1989 towards Jupiter using the Venus-Earth-Earth Gravity Assist (VEEGA) trajectory.
