A variety of man-made objects have been sent into outer space for decades, and as a very large and distinguished group, they have sent back important data. NASA has been at the forefront of these efforts here in the United States, and the Landsat Program has certainly been quite successful since its inception in the early 1970s. This website provides a wealth of information on the Landsat Program, and visitors can learn about its work in remote sensing. Visitors can use the right-hand side of the page to learn about different Landsat missions ranging from the original Landsat all the way up to Landsat Seven, which was launched in 1999. Each section contains information on Landsat's orbit, its instruments, and its vital statistics. Finally, a "Did You Know" section provides some key facts about some of the accomplishments of the Landsat program.
