Searching for life with the Terrestrial Planet Finder: Lagrange point options for a formation flying interferometer

In this paper, we describe the mission design for TPF assuming a distributed spacecraft concept using formation flight around both a halo orbit around L2 as well as a heliocentric orbit. Although the mission architecture is still under study, the next two years will include study of four design cncepts and a downselect to two concepts around 2005.

Simulation of formation flight near Lagrange points for the TPF Mission

In this paper, we focus on an orbit near the L***2***. Lagrange point. Our work in the study of the feasibility of formation flight near the Lagrange points indicates that 1) formation flight near L***2*** is dynamically possible for the TPF Mission and 2) linear control around a nonlinear baseline libration orbit near L***2*** is adequate for the TPF Mission.

Genesis Halo Orbit Station Keeping Design

As the fifth mission of NASA's Directory Program, Genesis is designed to collect solar wind samples for approximately two years in a halo orbit near the Sun-Earth L(sub 1) Lagrange point for return to the Earth.

Shoot the Moon

In 1991, the Japanese Hiten mission used a low energy transfer with a ballistic capture at the Moon which required less delta V than a standard Hohmann transfer to the Moon.

Halo Orbit Mission Correction Maneuvers Using Optimal Control

This paper addresses the computation of the required trajectory correction maneuvers (TCM) for a halo orbit space mission to compensate for the launch velocity errors introduced by inaccuracies of the launch vehicle.
