Dawn at Vesta - VIR

The Dawn spacecraft visited the asteroid 4 Vesta for the time period May 3, 2011 to Sept. 5, 2012. VIR is an imaging spectrometer that combines two data channels in one instrument, Visible (VIS) and Infrared (IR). The data sets linked below include raw (level 1a) and calibrated (level 1b) versions of all available images acquired during the Vesta Encounter.


Raw Data (Level 1a)

Status: Archived

The Version 2.0 L1a VIR Vesta volumes have been updated with the following changes with respect to the superseded Version 1.0 volumes below:

Dawn VIR IR raw, all Vesta phases, V1.0 DWNVVIR_I1A (19 Gb) DWNVVIR_I1A.tar.gz (16 Gb)
Dawn VIR VIS raw, all Vesta phases, V1.0 DWNVVIR_V1A (20 Gb) DWNVVIR_V1A.tar.gz (12 Gb)



Calibrated Data (Level 1b)

Status: Archived

The Version 2.0 L1b VIR Vesta volumes have been updated with the following changes with respect to the superseded Version 1.0 volumes below:

Data set: Browse: Download:
Dawn VIR IR calibrated, all Vesta phases, V2.0 DWNVVIR_I1B (38 Gb) DWNVVIR_I1B.tgz (30 Gb)
Dawn VIR VIS calibrated, all Vesta phases, V2.0 DWNVVIR_V1B (39 Gb) DWNVVIR_V1B.tgz (32 Gb)

Note: VIR ground correction factors, which may be applied to each band of the Ceres or Vesta L1b VIR cubes to correct for a positive slope when compared to groundbased spectra of the same target, will be included in the L1b Ceres VIR data volumes. Until they can be added to the volumes, they are available for download in the zip file VIR_CORRECTION_FACTORS-170907.zip

Version 1.0, superseded:

The Version 1.0 VIR level 1B data has the 3 micron region set to zero (specifically, the range 2.534 - 3.272 microns). The calibration contained artifacts in this range which the VIR team believed made the V1.0 calibrated data unusable. See Version 2.0 above for an updated calibration with the 3 micron region restored.
