May 15th, 2023 - MEX HRSC new Version 4 map projected data (REFDR4) data have been loaded into ODE
- HRSC new Version 4 of map projected RDR data (REFDR4) have been loaded into ODE, with coverage from January 1, 2019, through August 8, 2022 (Orbit 18976-23498).

Note: Version 3 of the HRSC map-projected dataset (REFDR3) is being superseded by a version 4 dataset (REFDR4). The new version is based on version 4 of the radiometrically calibrated images. The revision details are described in chapter 2.4 of the HRSC EAICD in the document directory of each volume. In addition, the JPEG 2000 images in the version 3 dataset have been replaced by GeoTIFF versions that are located in the EXTRAS subdirectory.
The version 4 dataset is being divided into multiple volumes based on mission phase as has been done for the radiometrically calibrated dataset. The new data products will be released from the most recent mission phase (extended mission eight) and going backward in time to the beginning of the mission. The version 3 map projected dataset will be transferred to the NSSDCA deep archive for permanent backup storage and taken offline at the Geosciences Node about 6 months after the complete set of version 4 volumes is available.
