As NASA representatives said in the new ScienceCasts podcast, more than 4 million have been collected to date.
For example, with their help, scientists can trackchanges on our planet over long periods of time. Lake Toshka and Lake Nasser in Egypt, for example, have been regularly photographed by the station for the past 20 years. This is partly because the water levels of these lakes change dramatically from month to month month, continually impacting agriculture in the region. Researchers able to observe these bodies of water over long periods of time through crew surveys can better study these processes.

Also, the film crew watched for a long timeViedma Glacier in southern South America. Over the years, its length has significantly decreased, and photographs allow researchers to observe these processes and compare the movement of the glacier with data on climate change.

You can also ask for a film crewcapture an event such as a hurricane, wildfire, flood or volcanic eruption. The photo below shows the flooding in Colombia. “This was one of a series of photographs used by international first responders to update their flood maps. As a result, it helped organize a rescue operation for local villagers who were stranded by rising waters,” Andrea Wenzel, a geologist in the Geosciences and Remote Sensing Division who handles photography requests for ISS crew members, said in a podcast.
