You might remember that we were planning on releasing HiRISE images to the public on a monthly basis. That plan was delayed by issues with our processing software, hardware and other events. A productive summer working on these issues culminated last week with one of our larger releases of Mars images! Here are some statistics about our September 2009 release, which includes the images the HiRISE camera took of the Martian surface between Mars Reconnaissance Orbiter (MRO) orbits 12,600 to 14,199, or roughly April 4 through August 6, 2009:
- 2,996 RDRs, 1 TB
- 42,370 EDRs, 1 TB
- 34,481 RDR Extras, 1.6 TB
- 83,784 EDR Extras, 0.02 TB
- 636 Anaglyphs, 0.01 TB
Totals for this release: 163,631 image products, 3.6 TB
This brings our total released product numbers and data volume to:
- 22,676 RDRs, 12 TB
- 317,120 EDRs, 10.4 TB
- 192,270 RDR Extras, 15.3 TB
- 612,769 EDR Extras, 0.1 TB
- 2,892 Anaglyphs, 0.5 TB
Total: 1,148,363 images, 37.5 TB
In summary, we released nearly 1500 observations, most of those with both black & white and color RDR products. Several newer observations matched up with older observations from a slightly different angle of the same location on the surface, resulting in 636 awesome new anaglyphs. The RDRs are the fully processed, geometrically projected products best for scientific inquiry. If you really want to, though, anyone can download and process HiRISE data from scratch. You can do this using ISIS software, which is publicly available for free download. See the ISIS Web site for download information, processing instructions, and tutorials.
Starting this week, I will be looking over the observations taken August 6 through August 26 before MRO went into safe mode and make sure they are ready for release. We plan to release these images in early October. We are also in the process of reprocessing those Extended Science Phase mission images prior to all the latest processing pipeline fixes and updates. Once we are satisfied with that data set, we will release them to the public and then start reprocessing the images from the Primary Science Phase…a major project that should keep me and the rest of Downlink busy for several months!
