The Astrodynamics Primer on Cislunar and Translunar Space
Aaron J. Rosengren, Anjali Rawat, Bhanu Kumar +1
The Earth-Moon environment is multiscale and strongly nonuniform, yet it is often discussed as a single cislunar regime. In reality, circumterrestrial space is partitioned by chang…
Analytical estimates for heliocentric escape of satellite ejecta
Jose Daniel Castro-Cisneros, Renu Malhotra, Aaron J. Rosengren
We present a general analytic framework to assess whether impact ejecta launched from the surface of a satellite can escape the gravitational influence of the planet--satellite sys…
A dynamical coherency gate for state recovery: Statistical requiem for the long arc of cislunar orbital mis-prediction
Binyamin Stivi, Vishnuu Mallik, Lamberto Dell'Elce +1
We present a statistically grounded methodology for recovering physically consistent initial conditions from historical two-line element sets (TLEs), enabling accurate long-arc tra…
Lunar impact ejecta flux on the Earth
Jose Daniel Castro-Cisneros, Renu Malhotra, Aaron J. Rosengren
The transfer of material between planetary bodies due to impact events is important for understanding planetary evolution, meteoroid impact fluxes, the formation of near-Earth obje…
The Sensitivity to initial conditions of the Co-orbital outcomes of Lunar Ejecta
Jose Daniel Castro-Cisneros, Renu Malhotra, Aaron J. Rosengren
Lunar ejecta, produced by meteoroidal impacts, have been proposed for the origin of the near-Earth asteroid (469219) Kamo'oalewa, supported by its unusually Earth-like orbit and L-…
