In 2014, the GVSU Art Gallery hosted an exhibition titled “The History of Space Photography” that featured over 50 noteworthy images from the last 50 years of space exploration. Images included some of the earliest black and white photographs of the moon to more recent image taken with the Mars Curiosity rover. These images were captured by astronauts, astronomers, and data visualization experts. This photograph shows the glacier recession at the Breidamerkurjokull glacier in Iceland. The data from 1973 is taken from Landsat 1 and the 2000 data is from Landsat 7. Almost all glaciers on the Earth are currently shrinking, a probable result of global warming.
