VISIR observations of the near-Earth asteroid 3908 Nyx in photometric N- and Q-band imaging mode and in low resolution N-band spectroscopy mode.
Nyx is a basaltic near-Earth asteroid with an extremely rough surface and the proposed target for the "Deep Interior" mission. The VISIR monitoring observations will allow us:
- to derive a high quality radiometric size and albedo
- to distinquish between a bare rock surface and a regolith covered surface
- to explore the surface roughness, cratering and the surface mineralogy
High-accuracy N- and Q-band photometry and low resolution spectroscopy at high S/N, observations are limited by signal processing/calibration uncertainites.
