Dr. Martin W. Lo is a member of the Navigation and Mission
Design Section at the Jet Propulsion Laboratory, California
Institute of Technology. Lo received his PhD from Cornell
University (1980) and his BS from the California Institute
of Technology in mathematics. As Mission Design Manager, he
led the development of the trajectory for the Genesis Mission
which launched on August 8, 2001 and is now collecting Solar
Wind samples in orbit about L1. He is currently supporting
the mission design and technology development of the Terrestrial
Planet Finder mission.
He is the organizer of the Lagrange Group, an interdisciplinary
and international group of researchers and engineers from
universities, NASA centers, and industry whose focus is on
the development of nonlinear astrodynamics techniques with
applications to space missions and dynamical astronomy. At
the request of the NASA Exploration Team, he demonstrated
that formation flight in halo orbits is practical for the
Terrestrial Planet Finder mission from the trajectory and
mission design point of view.
He also conceived of a novel approach for human servicing
of libration missions such as the Terrestrial Planet Finder
at a Gateway Module in halo orbit about the Lunar L1. This
provides a cost effective and efficient approach for human
servicing. The spacecraft requiring service may be moved between
the Earth libration orbits and the Lunar Gateway module via
ultra low energy trajectories in the InterPlanetary Superhighway.
This is a vast system of tunnels and passageways in space,
discovered by Lo, which connects the whole Solar System and
is generated by the Lagrange Points of all of the planets
and moons. Not only does the InterPlanetary Superhighway provide
low energy orbits for space missions, it is also traveled
by comets and asteroids throughout the Solar System. Comet
Shoemaker-Levy 9 and the asteroid which killed the dinosaurs
both traveled in impact orbits which are similar to the Genesis
orbit. Thus the InterPlanetary Superhighway is crucial to
the development of life on Earth. Lo believes that the InterPlanetary
Superhighway may play a key role in our understanding of low-thrust
trajectory design for spacecraft using advanced electric or
nuclear propulsion.
He is also leading the development of LTool, JPL's new mission
design tool which uses dynamical systems techniques, or "chaos
theory" to design highly nonlinear trajectories. His professional
interests include mission design, the three body problem,
satellite constellation coverage analysis, dynamical astronomy,
applied dynamical systems theory, and computational mathematics.
