Spectral properties of bright deposits in permanently shadowed craters on Ceres
Stefan Schröder, Norbert Schörghofer, Erwan Mazarico +1
Bright deposits in permanently shadowed craters on Ceres are thought to harbor water ice. However, the evidence for water ice presented thus far is indirect. We aim to directly det…
Potential and scientific requirements of optical clock networks for validating satellite gravity missions
Stefan Schröder, Simon Stellmer, Jürgen Kusche
The GRACE and GRACE-FO missions have provided an unprecedented quantification of large-scale changes in the water cycle. However, it is still an open problem of how these missions'…
Spectrophotometric analysis of the Ryugu rock seen by MASCOT: Searching for a carbonaceous chondrite analog
Stefan Schröder, Katharina Otto, Hannah Scharf +11
We analyze images of a rock on Ryugu acquired in situ by MASCam, camera of the MASCOT lander, with the aim of identifying possible carbonaceous chondrite (CC) analogs. The rock's r…
Resolved Photometry of Vesta Reveals Physical Properties of Crater Regolith
S. E. Schröder, S. Mottola, H. U. Keller +2
During its year-long orbital mission, the Dawn spacecraft has mapped the surface of main-belt asteroid Vesta multiple times at different spatial resolutions and illumination and vi…
Laboratory Observations and Simulations of Phase Reddening
S. E. Schröder, Y. Grynko, A. Pommerol +3
The visible reflectance spectrum of many solar system bodies changes with changing viewing geometry for reasons not fully understood. It is often observed to redden (increasing spe…
Variegation and space weathering on asteroid 21 Lutetia
S. E. Schröder, H. U. Keller, S. Mottola +4
During the flyby in 2010, the OSIRIS camera on-board Rosetta acquired hundreds of high-resolution images of asteroid Lutetia's surface through a range of narrow-band filters. While…
Resolved Spectrophotometric Properties of the Ceres Surface from Dawn Framing Camera Images
S. E. Schröder, S. Mottola, U. Carsenty +9
We present a global spectrophotometric characterization of the Ceres surface using Dawn Framing Camera (FC) images. We identify the photometric model that yields the best results f…
Spectrophotometric properties of dwarf planet Ceres from the VIR spectrometer on board the Dawn mission
M. Ciarniello, M. C. De Sanctis, E. Ammannito +14
We study the spectrophotometric properties of dwarf planet Ceres in the VIS-IR spectral range by means of hyper-spectral images acquired by the VIR imaging spectrometer on board th…
Surface Albedo and Spectral Variability of Ceres
Jian-Yang Li, Vishnu Reddy, Andreas Nathues +21
Previous observations suggested that Ceres has active but possibly sporadic water outgassing, and possibly varying spectral characteristics in a time scale of months. We used all a…
