ASIME 2018 White Paper. In-Space Utilisation of Asteroids: Asteroid Composition -- Answers to Questions from the Asteroid Miners
Amara L. Graps, Angel Abbud-Madrid, Paul Abell +41
In keeping with the Luxembourg government's initiative to support the future use of space resources, ASIME 2018 was held in Belval, Luxembourg on April 16-17, 2018. The goal of ASI…
Tomographic inversion of gravity gradient field for a synthetic Itokawa model
Liisa-Ida Sorsa, Mika Takala, Patrick Bambach +6
This article investigates reconstructing the internal mass density of a numerical asteroid model using the gradient of a simulated gravity field as synthetic measurement data. Our…
Bistatic full-wave radar tomography detects deep interior voids, cracks and boulders in a rubble-pile asteroid model
Liisa-Ida Sorsa, Mika Takala, Patrick Bambach +3
In this paper, we investigate full-wave computed radar tomography (CRT) using a rubble-pile asteroid model in which a realistic shape (Itokawa) is coupled with a synthetic material…
DISCUS - The Deep Interior Scanning CubeSat mission to a rubble pile near-Earth asteroid
Patrick Bambach, Jakob Deller, Esa Vilenius +5
We have performed an initial stage conceptual design study for the Deep Interior Scanning CubeSat (DISCUS), a tandem 6U CubeSat carrying a bistatic radar as main payload. DISCUS wi…
Far-Field Inversion for the Deep Interior Scanning CubeSat
Mika Takala, Patrick Bambach, Jakob Deller +6
This study aims at advancing mathematical and computational techniques for reconstructing the interior structure of a near earth asteroid (NEA) via Computed Radar Tomography (CRT).…
Multigrid-based inversion for volumetric radar imaging with asteroid interior reconstruction as a potential application
Mika Takala, Defne Us, Sampsa Pursiainen
This study concentrates on advancing mathematical and computational methodology for radar tomography imaging in which the unknown volumetric velocity distribution of a wave within…
The effect of hardware-computed travel-time on localization accuracy in the inversion of experimental (acoustic) waveform data
Mika Takala, Timo D. Hämäläinen, Sampsa Pursiainen
This study aims to advance hardware-level computations for travel-time tomography applications in which the wavelength is close to the diameter of the information that has to be re…
