The Visual and Infrared Mapping Spectrometer (VIMS) instrument
onboard the Cassini spacecraft observed the system of Saturn,
acquiring spectral cubes in the range 0.4-5.2 microns. This service
focuses on Saturn satellites, and provides access to calibrated and
ancillary data, computed as described here:
https://vims.univ-nantes.fr/info/isis-calibration. It also provides
direct links to a larger web site with previews.
The Chandra X-ray Observatory is the U.S. follow-on to the Einstein
Observatory and one of NASA"s Great Observatories.
Chandra was formerly known as AXAF, the Advanced X-ray
Astrophysics Facility, but renamed by NASA in December, 1998.
Originally three instruments and a high-resolution mirror carried in
one spacecraft, the project was reworked in 1992 and 1993. The Chandra
spacecraft carries a high resolution mirror, two imaging detectors,
and two sets of transmission gratings. Important Chandra features are:
an order of magnitude improvement in spatial resolution, good
sensitivity from 0.1 to 10 keV, and the capability for high spectral
resolution observations over most of this range.
The Chandra Source Catalog (CSC) includes information about X-ray
sources detected in observations obtained using the Chandra X-ray Observatory.
Release 2.0 of the catalog includes 317,167 point, compact, and extended
sources detected in ACIS and HRC-I imaging observations released
publicly prior to the end of 2014.
Observed source positions and multi-band count rates are reported, as
well as numerous derived spatial, photometric, spectral, and temporal
calibrated source properties that may be compared with data obtained
by other telescopes. Each record includes the best estimates of the
properties of a source based on data extracted from all observations
in which the source was detected.
The Chandra Source Catalog is extracted from the CXC"s Chandra Data
Archive (CDA). The CXC should be acknowledged as the source of Chandra data.

Pic du Midi de Bigorre in the French Pyrenees is the place where coronagraphic images were first realized, by Bernard Lyot in the 1930s. Since then, the solar instruments at Pic du Midi regularly provide images of the solar disc, solar prominences and solar corona.

Description:
Illumination by the Sun of each face of the comet 67P/Churyumov-Gerasimenko based on the shape model
CSHP_DV_130_01_LORES_OBJ.OBJ. The service provides the cosine between the normal of each face (in the same order as the faces defined in the shape model) and the Sun direction; both
numerical values and images of the illumination are available. Each map is defined for a given position of the Sun
in the frame of 67P (67P/C-G_CK). Longitude 0 is at the center of each map. The code is developed by A. Beth,
Imperial College London, UK and the service is provided by CDPP (http://cdpp.eu). Acknowlegment: The illumination models
have been developed at the Department of Physics at Imperial College London (UK) under the financial support of STFC
grant of UK ST/N000692/1 and ESA contract 4000119035/16/ES/JD (Rosetta RPC-PIU). We would also like to warmly
thank Bernhard Geiger (ESA) for his support in validating the 2D-illumination maps.

Description:
The Mars Crater Catalog by S.J. Robbins was generated from THEMIS
Daytime IR and Viking MDIM 2.1 global mosaics of Mars. Craters were
selected using 5 points along the rim. The table is statistically
complete to the diameter of ~1.0 km. The table contains morphologic
and morphometric data for craters with diameter larger than 3 km. The
Prometheus basin has been excluded from the Catalog due to technical
issues.

Mars_dust provides a multiannual climatology of Martian airborne dust as measured by various space missions. The retrieved column dust optical depth is mapped for each Martian year and formatted as cubes with time in the 3rd dimension. Two versions are available: irregularly gridded maps, and regular maps produced by kriging. These latter maps are used as column-integrated dust scenarios in the Mars Climate Database (MCD v5). The detailed description of the methodology and dataset can be found in: Montabone et al (2015) Icarus 251, pp. 65-95https://doi.org/10.1016/j.icarus.2014.12.034 ; Montabone et al (2020) JGR-Planets https://doi.org/10.1029/2019JE006111
