    Ground Track Acquisition and Maintenance Maneuver Modeling for Low-Earth Orbit Satellite by Byoung-Sun Lee, Jong-Won Eun, Charles E. Webb

    Published 1997-12-01
    “…This paper presents a comprehensive analytical approach for determining key maneuver parameters associated with the acquisition and maintenance of the ground track for a low-earth orbit. A livearized model relating changes in the drift rate of the ground track directly to changes in the orbital semi-major axis is also developed. …”

    Low earth orbit nanosatellite: influence of heat dissipation on passive thermal analysis by Amine Akka, Farid Benabdelouahab, Randa Yerrou

    Published 2022-10-01
    “…To meet the thermal stability requirements, it becomes statutory to manage passive and active thermal control to reach this goal while a variety of factors, such as high-powered components, sunlight and shadow on orbit, or a tight spacecraft layout, remain imposed.A spherical nanosatellite thermal analysis was performed to show the effect of energy dissipation in a low earth orbit and the stability of the system with a special attention to batteries, which persist as the weak link among electronics parts. …”

    Space Radiation: The Number One Risk to Astronaut Health beyond Low Earth Orbit by Jeffery C. Chancellor, Graham B. I. Scott, Jeffrey P. Sutton

    Published 2014-09-01
    “…One or more of these deleterious health effects could develop during future multi-year space exploration missions beyond low Earth orbit (LEO). Shielding is an effective countermeasure against solar particle events (SPEs), but is ineffective in protecting crew members from the biological impacts of fast moving, highly-charged galactic cosmic radiation (GCR) nuclei. …”
