We propose a distributed close-range survey of hundreds of asteroids representing many asteroid families, spectral types and sizes. This can be implemented by a fleet of nanospacecraft (e.g., 4-5-unit CubeSats) equipped with miniature imaging and spectral instruments (from near ultraviolet to near infrared). To enable the necessary large delta-v, e...

ESTCube-1 is a one-unit CubeSat that has been in orbit since May 2013. It was launched to a Sun-synchronous 670 km altitude polar low Earth orbit, and its primary mission objective was to centrifugally deploy a tether as a part of the first in-orbit demonstration of electric solar wind sail (E-sail) technology. The electrical power system, the comm...

Conference Paper
Full-text available
The development of attitude control systems in recent years have increasingly focused on Fault Tolerant Control (FTC) capabilities to deal with sensor and actuator faults as well as actuator saturation. The FTC capabilities could either be active or passive with the former involving real-time fault detection and isolation schemes. A detailed integr...

Nanospacecraft could enable detailed characterization of many asteroids in a small timeframe by launching multiple spacecraft simultaneously to visit a large set of targets. To be able to characterize as large of a set of asteroids as possible, however, visits to individual asteroids would be limited to flybys, which would have to be autonomous. As...

A voltage-biased metallic tether creates an electrostatic potential structure around itself. If put into flowing plasma, the electrostatic field deflects the trajectories of plasma ions. The resulting momentum transfer from plasma to the tether can be used for propulsive purposes. The electric solar wind sail (E-sail) is one such application. The E...

Space missions are dynamic in nature and therefore the on-board software on spacecraft often needs to be updated after deployment into space. Nanosatellites are no exception, but their update options are often not implemented. In this paper four variants of a method are demonstrated for remote firmware updates on nanosatellite systems with low memo...

https://github.com/SISPO-developers/sispo SISPO is a newly developed, physically-based imaging simulator for small solar system body fly-by and terrestrial planet surface mission simulations. The image simulator utilises the open-source 3D visualisation system Blender and its Cycles rendering engine, which supports physically based rendering capabilities and procedural micropolygon displacement texture generation. The simulator concentrates on realistic surface rendering and has supplementary models to produce realistic dust- and gas-environment optical models for comets and active asteroids. The framework also includes tools to simulate the most common image aberrations, such as tangential and sagittal astigmatism, internal and external comatic aberration, and simple geometric distortions. The model framework's primary objective is to support small-body space mission design by allowing better simulations for characterisation of imaging instrument performance, assisting mission planning, and developing computer-vision algorithms. SISPO allows the simulation of trajectories, light parameters and camera's intrinsic parameters.
