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)

Version 1.0 Status: Archived (liens all resolved)
Data set: Browse: Download:
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)


Version 2.0 Status: Certified with minor liens as of August 10, 2016

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

Data set: Browse: Download:
Dawn VIR IR raw, all Vesta phases, V2.0 DWNVVIR_I1A (19 Gb) DWNVVIR_I1A-160617.tgz (15 Gb)
Dawn VIR VIS raw, all Vesta phases, V2.0 DWNVVIR_V1A (19 Gb) DWNVVIR_V1A-160617.tgz (12 Gb)

Note: These two volumes have been released while still in liens-resolution. Please consult the liens list before using these data.


Calibrated Data (Level 1b)

Version 1.0 Status: Archived (liens all resolved)

Note: The VIR level 1B data has had 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 for an updated calibration with the 3 micron region restored.

Dawn VIR IR calibrated, all Vesta phases, V1.0 DWNVVIR_I1B (38 Gb) DWNVVIR_I1B.tar.gz (26 Gb)
Dawn VIR VIS calibrated, all Vesta phases, V1.0 DWNVVIR_V1B (40 Gb) DWNVVIR_V1B.tar.gz (32 Gb)


Version 2.0 Status: Certified with minor liens as of August 10, 2016

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

Data set: Browse: Download:
Dawn VIR IR calibrated, all Vesta phases, V2.0 DWNVVIR_I1B (38 Gb) DWNVVIR_I1B.tar.gz (30 Gb)

Note: This volume has been released while still in liens-resolution. Please consult the liens list before using these data.

Note: The Vesta V2.0 VIR VIS L1b volume was not certified at review because it was discovered that a component of the VIR VIS processing, the detilt algorithm, has not been documented. This volume will be released soon once the detilt algorithm has been documented. Note that the detilt algorithm was also part of the processing of all previously released VIR VIS L1b data, including Ceres Approach and RC3, and Vesta all phases. VIR IR is not affected.


VIR Vesta Global Maps (Level 2)

Status: Certified with minor liens as of August 10, 2016


Data set: Browse: Download:
Dawn VIR Vesta Global Maps DWNVVIR_2 (2.3 Gb) DWNVVIR_2_20160606.zip (908 Mb)

Note: This volume has been released while still in liens-resolution. Please consult the liens list before using these data.
