A passive de-orbiting strategy for high altitude CubeSat missions using a deployable reflective balloon [PDF]

open access: yes, 2011
A de-orbiting strategy for small satellites, in particular CubeSats, is proposed which exploits the effect of solar radiation pressure to increase the spacecraft orbit eccentricity so that the perigee falls below an altitude where atmospheric drag will ...

Displaced solar sail orbits : dynamics and applications [PDF]

open access: yes, 2010
We consider displaced periodic orbits at linear order in the circular restricted Earth-Moon system, where the third massless body is a solar sail. These highly non-Keplerian orbits are achieved using an extremely small sail acceleration.

Combining Solar Science and Asteroid Science with the Space Weather Observation Network (SWON) [PDF]

open access: yes, 2011
The peculiarity of space weather for Earth orbiting satellites, air traffic and power grids on Earth and especially the financial and operational risks posed by damage due to space weather, underline the necessity of space weather observation.

Solar radiation pressure augmented deorbiting from high altitude sun-synchronous orbits [PDF]

open access: yes, 2012
This paper discusses the use of solar radiation pressure (SRP) augmented deorbiting to passively remove small satellites from high altitude Sun-synchronous orbits. SRP-augmented deorbiting works by deploying a light-weight reflective inflatable device to

Control of colocated geostationary satellites [PDF]

open access: yes, 1996
Control of the inter-satellite distances within a cluster of colocated satellites located in the same GEO window is examined with regards to the close approaches between pairs of satellites. Firstly, the orbital evolution and station keeping control of a

ANALYSIS OF SELF – GRAVITATING PLANETARY SATELLITES IN THE SOLAR SYSTEM

open access: yesOdessa Astronomical Publications, 2016
As of today there have been more than 180 planetary satellites discovered in the Solar system, and the number of outer moons found continues to grow. Most of those natural satellites have insufficient mass and are able to retain their shape only due to ...

Thin-shell Tidal Dynamics of Ocean Worlds

open access: yesThe Planetary Science Journal, 2023
Several solar system moons harbor subsurface water oceans; extreme internal heating or solar irradiation can form magma oceans in terrestrial bodies. Tidal forces drive ocean currents, producing tidal heating that affects the thermal−orbital evolution of

Satellite Requirements for Observation of Close Proximity Celestial Bodies

open access: yesEngineering Proceedings, 2022
Celestial bodies of our solar system remain as a major unexplored and unexploited reserve of natural resources available to humans. Furthermore, those constitute a valuable source of information about the origins and evolution of the solar system and an ...

Retrograde Predominance of Small Saturnian Moons Reiterates a Recent Retrograde Collisional Disruption

open access: yesThe Planetary Science Journal
We report the discovery and careful orbital determination of 64 new irregular moons of Saturn found in images taken using the Canada–France–Hawaii Telescope from 2019 to 2021, bringing the total number of Saturnian irregulars to 122.
