Dawn primary instrument data:

Data type Browse/Download Description
Images Framing Camera (FC) Mars/Cruise/Calibration FC1 and FC2 are identical optical cameras
with a 1024x1024 pixel CCD. Filters include one broadband
and seven narrow-band filters from 438-965 nm.
Framing Camera Vesta
Framing Camera Ceres
Spectra VIS/IR Spectrometer (VIR) Cruise VIR is a moderate-resolution imaging
spectrometer with a 0.25-1 micron visible channel and a
0.95-5 micron infrared channel.
VIS/IR Spectrometer Vesta
VIS/IR Spectrometer Ceres
Nuclear Gamma-Ray/Neutron Detector Mars/Cruise (GRaND) GRaND is a nuclear spectrometer which measures
the spectrum of planetary gamma rays and neutrons which
originate from galactic cosmic ray interactions and the
decay of radioelements within the regolith.
