Asteroid (99942) Apophis is a potentially hazardous asteroid. The Korea Astronomy and Space Science Institute (KASI) recently proposed a rendezvous mission with Apophis, with a planned asteroid observation campaign to help determine the mission strat

The deflecting asteroid by dusting (DAD) mission addresses the challenges of deflecting a potentially hazardous asteroid (PHA) that has a large probability of impacting Earth. It is an innovative a...

Following the testing of a pathfinder hypertelescope in the southern Alps, versions usable on the Moon or in space are proposed. The large resolution gain expected for direct imaging in a narrow “Direct Imaging Field”, with a high limiting magnit

A novel concept for the deflection of rotating asteroids is presented, based on the conversion of the asteroid rotational kinetic energy into translational kinetic energy. Such conversion is achieved using an orbital siphon, a tether-connected chain

This paper investigates the possibility to navigate one or more spacecraft in the proximity of an asteroid binary system using only optical measurements. The approach proposed in this paper assumes only limited prior knowledge of the shape and orbita

A collision of an asteroid with the Earth in the future is always considered as a probabilistic event because the asteroid orbit determined from observations with random errors inevitably contains an uncertainty in its parameters. To establish the pr
