Abstract We present results from an occultation of a star by the asteroid (269) Justitia on 2023 August 31 UT using deployment 34 stations. Of deployed stations, 29 were successful in collecting useful data and 19 recorded positive event. All stations regularly spaced 2.45 km apart cross-track direction to cover ±3 σ ephemeris uncertainty with planning diameter 59 km. find that shape is irregular, large-scale facets circular-equivalent radius range 28.5–28.9 The inferred albedo p V = 0.072 ±...
A system of Lunar relay satellites has been proposed to address communication and navigation needs ensure robustness for the variety upcoming robotic human exploration missions Moon. The relays are envisioned estimate self-position time knowledge onboard, allowing provide in-situ services in cis-Lunar environment. quality accuracy those highly dependent on performance itself. To assess performance, a series orbit determination (OD) Monte Carlo (MC) simulations run using gravity modeling up...
