Ross Beyer, my co-worker at NASA, performed a Google Tech Talk early this month. It is now available online and you can watch it above. I don’t want to give any spoilers, but a certain stereo something is mentioned in this talk.
The Google community silently released a few new features for their Mars mode in Google Earth. MER-B, Opportunity, now has an updated traverse path thanks to a fellow at the Unmanned Spaceflight forum along with a new base map that Ross created. However I’m really excited about a new CTX Global Map that is available. Below is a screen shot:
From this high view you can see that that CTX hasn’t imaged all of Mars. This is expected. CTX isn’t trying to image all of Mars, it is simply the context imager for HiRISE. Meaning that CTX tends to roll tape only when HiRISE is. Never the less, the imagery is still beautiful and, in my opinion, shows more detail that the default base layer from an HRSC composite.
This mosaic was created by simply downloading all CTX data from NASA’s PDS servers and then calibrating and map projected the imagery with USGS’s ISIS software. The composite was then made with in house software from our team at NASA Ames Research Center. This is a Vision Workbench combination plus our Plate Filesystem. It is the same software we used to do a global MOC-NA and HiRISE mosaic for Microsoft’s World Wide Telescope. Unfortunately, I believe those servers have bit the dust. Regardless, if you have free time, I encourage you to check out the CTX Mosaic and Opportunity traverse in Google Earth. Click the planet, select “Mars”, and then in the bottom left select “CTX Mosaic” under “Global Maps”.
