Summer Internship at NASA Ames Research Center

Help us put scientific papers on the map—of Mars!

Here at NASA Ames, we're working with Google, Inc., and the SAO/NASA Astrophysics Data System to get scientific papers geo-located on Mars. Although we'll start with explicitly geo-locating a few, we want to enable a system so that the scientific community itself can add geo-location information to already-published works, and encourage future publications to include easier to parse geo-location information.

Little known features in Google Earth's Mars mode

Lots of blogs (here and here) and news outlets have covered some of the great new Mars features in Google Earth. I will assume that you have read those blogs, watched various demonstration videos, or even watched some of the Guided Tours available in the Google Earth client itself. I will most certainly assume that you have at least taken a cursory spin around the Mars in Google Earth (we refer to it as Google Mars internally—at Ames and Google—but since that has meant the 2D Google Maps API Mars maps for so long, I don't want to confuse people).

For the discerning visitor I present a number of little perks that you might not notice. Mars in Google Earth is primarily targeted at a general public audience, but we've also slipped in some pretty cool extras (if I do say so myself) for scientists and advanced explorers alike.

Cropping HiRISE JPEG 2000 images

HiRISE images are huge, frequently 1.5 GB, and they are in JPEG 2000 format, which many image software programs don't (yet) handle. So what do you do if you need to work with just a small area of that image at high resolution? This post explains how to get that subframe.

Using Google Earth as a Mars Browser

Although there are many issues with putting Mars data into Google Earth, most notably the fact that the best we can currently do is wrap the Earth's sphere in Mars basemaps. However, we can make Google Earth a remarkable tool for locating Mars Reconnaissance Orbiter (MRO) data by being a little clever.

The steps below outline how to configure Google Earth with Martian basemaps, and then how to plot data from the MRO mission.

importing MOC into GMT with grdraster

Hi. Has anyone successfully imported MOC images into GMT using grdraster? I have been working on this for over a week, and I (as well as several others helping me) have had no luck. Some issues:

1. Should the MOC images, processed with ISIS, be map projected or not? Altered with mocaspect?

2. What files are acceptable as input to grdraster? I found online that .bmp, .gif, .jpeg, .jpg, .tif, and .wbmp are raster images. I am only able to get my files into .tif, .raw, or .bmp files (ISIS2 dform and ISIS3 isis2std aren't working properly on the machines I use). I have not managed to get any of these data types into GMT (problems with -I (increment) and/or data type definitions in grdraster.info file).

point photoclinometry / stereo images

Hi. I am looking into doing point photoclinometry for certain regions of Mars. I know how to process MOC images with ISIS, but does anyone know how to get the raw DN values of each pixel? Also, has anyone used SOCET SET to make stereo images?

how to find MOC images on the PDS?

I want to find a specific MOC image on the PDS http://pds.jpl.nasa.gov/. I do a "Data Search", select Instrument "Mars Oribiter Camera", click "Go!", and get two results. But where do I go from there?

qview measure

I am using ISIS2 and qview to look at processed MOC cubes. When I try to use the qview measure tool, one end of the measuring line is always trapped in the upper left hand corner. Has anyone else experienced this and/or found a way to fix this?

MGS data tools

Not quite sure where to start with data from the Mars Global Surveyor spacecraft? This article contains links to the raw data, and also links to the various software tools that members of the community have created to analyze the data itself.

MOC images vs press releases

How do I get science-quality MOC images from a press release image I like? For example, I want to use this press release image:

http://www.msss.com/mars_images/moc/2004/04/30/

The numbering systems seem totally different though, so I don't know how to find that image in the data at:
