Abstract

Asteroids have many valuable resources such as minerals and volatiles, which can be brought back to Earth or used in space for space propulsion systems or space habitats and stations. Transportation to and from asteroids will require relatively massive vehicles capable of sustaining crew for long durations, while economizing on propellant mass. Thus, in the design of advanced space missions for exploration, mitigation, and mining of Near-Earth Asteroids (NEAs), developing new technology for low cost trajectories will play a key role. This paper is focused on NEA rendezvous mission design using fuel-minimizing trajectories that take advantage of the natural dynamics in the solar system. This energy efficient trajectory technology, called Interplanetary Super Highway, allows long duration space missions with little fuel. Invariant manifolds, can carry a spacecraft immense distances with little or no expenditure. This patched three-body method of trajectory design is fairly well developed for impulsive propulsion. Here we advance the capabilities of the method by extending it to continuous, low-thrust, high specific impulse propulsion methods.
