We propose a novel strategy for precise landing of a space probe on an asteroid surface. In
Hayabusa mission, a Japanese asteroid sample-return spacecraft launched in 2003, a small …

In recent years, there has been significant interest in sending spacecraft to smallbodies in
our solar system, such as asteroids and comets, for the purpose of scientific study. Scientists …

Abstract The Japan Aerospace Exploration Agency (JAXA) has conducted an asteroid
sample return mission, Hayabusa2. The spacecraft was launched in 2014 and arrived at the …

For the probe descending and landing safely, a continuous control method based on
proportional plus derivative (PD) and nonsingular Terminal sliding mode was proposed …

Aimed at the multiple-constraint trajectory optimization problem in the descent phase of
small body landing exploration, Gauss pseudospectral method is used for the optimization …

To pinpoint land on the surface of irregular small bodies safely, an effective guidance and
control algorithm based on dynamic surface was presented. The relative orbit dynamic …
