Most of you are likely aware, or have seen photos of earth taken from the space shuttle or the International Space Station. However, did you know that NASA has a collection of photos featuring various national parks around the country? To be honest, many of the photos weren't all that impressive, in my opinion. There are a couple, such as Death Valley, or Crater Lake and North Cascades, that are quite compelling. However, the one photo that I was extremely impressed with was that of Grand Teton National Park:


To see other space photos of national parks you can browse through the NASA image gallery.

Ten Years of Global Fire Observations From Space

Ten Years of Global Fire Observations From Space

Friday, November 4, 2011

NASA recently released a series of new satellite data visualizations that show tens of millions of fires detected worldwide from space since 2002. The visualizations show fire observations made by the MODerate Resolution Imaging Spectroradiometer, or MODIS, instruments onboard NASA's Terra and Aqua satellites.

The short video below takes viewers on a narrated global tour of fires detected between July 2002 and July 2011. The fire data is combined with satellite views of vegetation and snow cover to show how fires relate to seasonal changes. The Terra and Aqua satellites were launched in 1999 and 2002, respectively.
