Contingency Trajectory Design for a Lunar Orbit Insertion Maneuver Failure by the LADEE Spacecraft
This paper presents results from a contingency trajectory analysis performed for the Lunar Atmosphere & Dust Environment Explorer (LADEE) mission in the event of a missed lunar-orbit insertion (LOI) maneuver by the LADEE spacecraft. The effects of varying solar perturbations in the vicinity of the weak stability boundary (WSB) in the Sun-Earth system on the trajectory design are analyzed and di...
متن کاملSun Safe Mode Controller Design for LADEE
This paper presents the development of sun safe controllers which are designed to keep the spacecraft power positive and thermally balanced in the event an anomaly is detected. Employed by NASA’s Lunar Atmosphere and Dust Environment Explorer (LADEE), the controllers utilize the measured sun vector and the spacecraft body rates for feedback control. To improve the accuracy of sun vector estimat...
متن کاملScattering Properties of Lunar Dust Analogs
A number of space missions are planned to explore the lunar exosphere which may contain a small population of dust particles. The objective of this paper is to present preliminary results from scattering experiments on a suspension of lunar simulants to support one such mission. The intensity of the light scattered from a lunar simulant is measured with a commercial version of the spectrometer ...
متن کاملValidation and Verification of LADEE Models and Software
The Lunar Atmosphere Dust Environment Explorer (LADEE) mission will orbit the moon in order to measure the density, composition and time variability of the lunar dust environment. The ground-side and onboard flight software for the mission is being developed using a “Model-Based Software” methodology. In this technique, models of the spacecraft and flight software are developed in a graphical d...
متن کاملPredictions for the Optical Scattering at the Moon, as Observed by the Ladee
Introduction: When viewing the lunar exosphere there appear to be three major sources of optical scattering that are typically observed: atomic line emissions from the exospheric gases [1]; the relatively bright coronal and zodiacal light (CZL) background [2]; and the putative scattering of sunlight by exospheric dust, which is also referred to as “lunar horizon glow” (LHG) [3]. The lunar exosp...
