I work at the Scientific Visualization Studio at NASA Goddard Space Flight Center. Below are a few of the animations I've done since starting here in 1998. If you click on any of the titles or images, you can download the full animation. They are in MPEG format and vary in size from about 2MB to 10MB, so it's helpful if you are on a fast connection. In some cases, the encoding isn't what I would like, but it's what I've got for now. Also, you may find some of them a bit dark if your system doesn't correctly deal with gamma.


This was one of the first things I did at the Studio. The Upper Atmosphere Research Satellite, UARS, carried instruments to study the ozone layer. This animation shows how ultraviolet light can break up molecular oxygen and form ozone.


The Mars Global Surveyor carries on it the Mars Orbiting Laser Altimeter, or MOLA, instrument. This device uses laser pulses to create a very accurate topographic map of Mars. By doing insanely clever rocket scientist things, they were also able to use MOLA to get an idea of the shape of the Martian mantle layer. This animation shows a cutaway of Mars, revealing the interior mantle layer.

The Farallon Plate

The Farallon techtonic plate no longer exists. It subducted under the North American plate, and in so doing, caused the formation of the Rockies. The theory is that the Rockies are so far east of the plate boundary because Farallon didn't plunge down straight away, but scrapped the bottom of the North American plate for a while, then dove under. This animation illustrates that idea.

Salt Lake City Olympic Venue Tour, with Pushpins

The 2000 Winter Olympics were held in Salt Lake City and the surrounding area. This animation is a tour of the venues, which are marked with pushpins. For this project, I used Landsat 7 imagery, combined with topographic data for the Salt Lake City region.

Mount Kilimanjaro

Mount Kilimanjaro has had a permanent snowcap for all of recorded history. Now, due to global warming, that snow cap is going away. This animation, using Landsat imagery, shows how small the snowcap was in February 2000. This animation, done in December, 2002, got a lot of play on CNN, which was very satisfying!
