LOW-THRUST trajectories are becoming increasingly impor-tant in the design of space
missions. The technological developments that allowed ion propulsion to become a …

Focused on asteroid soft-landing mission scenario, this paper investigates the methods of
online gravity field modeling and trajectory optimization. Since the gravity field near …

IN RECENT years, considerable attention has been devoted to the problem offinding
innovative trajectories for spacecraft subjected to a low-thrust propulsion system. The focus …

NASA's Deep Space 1 and recently ESA's SMART-1 have shown the effectiveness of
lowthrust systems as primary propulsion devices. This opens the door to new kinds of …

An approach for the fast generation of a minimum-time, three-dimensional trajectory for a
spacecraft propelled by a solar sail with reflection control devices (RCDs) is presented using …

To expand mission capabilities that are required for exploration of the solar system,
methodologies to design optimal low-thrust trajectories must be developed. However, low …

Deep space exploration missions are a great fit for continuous-thrust spacecraft because of
their benefits of high specific impulse and extended operating period. However, when it …

Some insects can move towards female ones or their preys while minimizing the chance of
being aware from their natural background using a technique called motion camouflage. In …
