The threat of potential hazardous near-Earth asteroid (PHA) impact on Earth is increasingly attracting public attention. Monitoring and early warning of those PHAs are the premise of planetary defense. In this paper, we proposed a novel concept of su

This paper proposed a polynomial representation-based method for orbit determination (OD) of spacecraft with the unknown maneuver. Different from the conventional maneuvering OD approaches that rely on specific orbit dynamic equation, the proposed me

Asteroid anchoring is the premise for the spacecraft to conduct in-situ scientific exploration on the surface of a weak gravitational asteroid. There is not any precedent for successful anchoring on the asteroid surface all over the world. Ultrasonic

The rotation effect by a revolving two-bladed rotor on hydrodynamics of gas and particles over the particles layer in an open chamber has been numerically studied using a three-dimensional transient Euler-Euler two-fluid model (TFM). The collisional

The draft fan is used to generate a controlled transportation of particles to enhance entrainment of gas and particles from the particles bed. Present investigations show the entrainment behavior of particles induced by an axial 4-blade draft fan hov

The Main Belt Comet 133P/Elst-Pizarro is one of the targets in China’s asteroid exploration mission. To support this goal, gravity field estimation for this celestial object was simulated and analyzed using two-way and four-way range rate observati

The aerodynamics of gas-particle suspensions is simulated as an Euler-Euler two-fluid model in a revolving rotor over a particle bed. The interactions of collisions between the blade and particles and particle-particle interactions are modeled using
The past twenty years have seen an evolution in the definition and categorization of small bodies in the Solar System. While new types of bodies are being discovered at an increasing pace, objects familiar to us have been rediscovered with traits pre

Landing on the surfaces of small solar system bodies (3SBs) is a prerequisite for maximizing the value of probes and provides technical reserves for the resource development of 3SBs and crewed landings on their surfaces. Motivated by the purposes of
