7 min read Peering Homeward, 1972 By Laura Rocchio The scientists and engineers at NASA Goddard looking at the first MSS images were looking at just one band of data, so the images appeared black and white to them. The image shows the area on that July 25, 1972 image that initially had them [...]

4 min read My NASA Experience By Marcia J. Rieke The development of infrared detector arrays is intertwined with my experiences working on NASA projects. As an astronomer at a university, my interactions with NASA all start with a proposal in response to an opportunity. In 1983, near-infrared detector arrays were beginning to attract [...]

14 min read The Gestation of the Hubble By Nancy Grace Roman Looking through the atmosphere is like looking through a piece of old stained glass. The glass has defects that distort the image. The atmosphere also has defects that distort the image, but the defects in the atmosphere move, thus blurring the image [...]

Northern Japan, especially the island of Hokkaido, is home to some of the snowiest cities in the world. Sapporo, the island’s largest city and host of an annual snow festival, typically sees more than 140 days of snowfall, with nearly 6 meters (20 feet) accumulating on average each year.Michala Garrison, using MODIS data from NASA [...]

NASA/Chris Williams NASA astronaut Chris Williams pointed a camera out a window on the cupola as a set of CubeSats were deployed outside the Kibo laboratory module by a small satellite orbital deployer into Earth orbit. Students from Mexico, Italy, Thailand, Malaysia, and Japan designed the shoe-boxed satellites for a series of Earth observations and technology demonstrations. CubeSats are a class of nanosatellites – [...]
