Landing and Mobility Concept for the Small Asteroid Lander Mascot on Asteroid 1999 Ju3
To enhance the currently studied asteroid sample return mission HAYABUSA-2 by in-situ science the Institute of Space Systems of the German Aerospace Center (DLR) is in lead of a proposal for a lander called MASCOT (Mobile Asteroid Surface Scout). Its mass of 10 kg lies in between those of the HAYABUSA small lander MINERVA (1 kg) and the legged ROSETTA comet lander PHILAE (100 kg). In the succes...
متن کاملDesign and Analysis of Landing Trajectories and Low-Altitude Asteroid Flyovers
This article discusses the dynamics, analysis, and design of low-altitude flyovers and landing trajectories at asteroids. The theory presented in the article will be applicable to asteroid missions in general. The article will begin with a brief review of orbital dynamics in close proximity to asteroids or other irregularly shaped bodies, covering the special considerations that must be taken i...
متن کاملGeometric Control for Autonomous Landing on Asteroid Itokawa using Visual Localization
This paper considers the coupled orbit and attitude dynamics of a dumbbell spacecraft around an asteroid. Geometric methods are used to derive the coupled equations of motion, defined on the configuration space of the special Euclidean group, and then a nonlinear controller is designed to enable trajectory tracking of desired landing trajectories. Rather than relying on sliding mode control or ...
متن کاملDetection of structure in asteroid analogue materials and Titan’s regolith by a landing spacecraft
We compare measurements made by two impact penetrometers of different sizes and with different tip shapes to further understand penetrometer design for performing pentrometry on an asteroid. To this end we re-visit the interpretation of data from the Huygens’ penetrometer, ACC-E, that impacted Titan’s surface. In addition we investigate the potential of a spacecraft fitted with a penetrometer t...
متن کاملUniversity of Dundee Asteroid modeling for testing spacecraft approach and landing
Spacecraft exploration of asteroids presents a variety of autonomous navigation challenges that can be aided by virtual models to test and develop guidance and hazard avoidance systems. This paper describes the extension and application of graphics techniques to create high-resolution, virtual asteroid models to simulate cameras and other spacecraft sensors approaching and descending towards as...
