This paper presents and analyzes Reinforcement Learning (RL) based approaches to solve
spacecraft control problems. Different application fields are considered, eg, guidance …

Spaceflight is facing a sustainability problem in Earth orbit, where about 90% of all man-
made trackable objects are without functional use. Existing research activities on active …

Abstract Space debris is growing dramatically with the rapid pace of human exploration of
space, which seriously threatens the safety of artificial spacecraft in orbit. Therefore, the …

Solar sails, characterized by passive propulsion, have attracted an increasing attention of
researchers, which has important value in the field of deep space exploration. SIASAIL-I is …

Active debris removal (ADR) allows for the disposal of inactive satellites and larger objects,
preventing the build-up of space junk and allowing to replace aging agents in a …

Abstract Space debris have become exceedingly dangerous over the years as the number
of objects in orbit continues to increase. Active debris removal (ADR) missions have gained …

Application of the method of removal of space debris objects by an ion beam-the IBS method-
seems to be the most effective for cleaning the GEO region. This is due to the low energy …

Debris removal problem has become a consensus of international communities with the
dramatically increase of space debris. When the service spacecraft (Servicer) carries out …

The purpose of this paper is to study active removal of rotating space debris in space, a
conical harpoon was used to carry out penetration experiments on a single-axis rotating …

As the sole orbit data source of space objects for public access, the NORAD catalog
provides the basic orbital information in the form of two-line element (TLE) for various space …
