Landsat Satellite Missions
In a September 21, 1966 press release, Secretary of the Interior Stewart Udall announced that the DOI was launching "Project EROS (Earth Resources Observation Satellites)". Udall's vision was to observe the Earth for the benefit of all. He stated that "the program will provide us with the opportunity to collect valuable resource data and use it to improve the quality of our environment."
The Department of the Interior, NASA, and the Department of Agriculture then embarked on an ambitious effort to develop and launch the first civilian Earth observation satellite. Their goal was achieved on July 23, 1972, with the launch of the Earth Resources Technology Satellite (ERTS-1), which was later renamed Landsat 1. The launches of Landsat 2, Landsat 3, and Landsat 4 followed in 1975, 1978, and 1982, respectively.
When Landsat 5 launched in 1984, no one could have predicted that the satellite would continue to deliver high quality, global data of Earth’s land surfaces for 28 years and 10 months, officially setting a new Guinness World Record for "longest-operating Earth observation satellite." Landsat 6 failed to achieve orbit in 1993.
Landsat 7 successfully launched in 1999, Landsat 8 in 2013, and both satellites continue to acquire data.
The Landsat 9 satellite is being developed toward a launch readiness date of September 2021.

EarthNow! Landsat Image Viewer
The EarthNow! Landsat Image Viewer displays imagery in near real-time as Landsat 7 and Landsat 8 orbit the Earth. Along with the near real-time video stream, EarthNow! also replays acquisition recordings from a list of previous Landsat overpasses. When Landsat 7 or Landsat 8 are out of viewing range of a ground station, the most recent overpass is displayed.

Economic valuation of landsat imagery
Landsat satellites have been operating since 1972, providing a continuous global record of the Earth’s land surface. The imagery is currently available at no cost through the U.S. Geological Survey (USGS). A previous USGS study estimated that Landsat imagery provided users an annual benefit of $2.19 billion in 2011, with U.S. users accounting for...

Landsat helps bolster food security
One of the cruelest, most complex narratives in the world today (2019) is written in the hunger of sub-Saharan Africa. When famine is the only yield from the scorched Earth, survival often depends on a heart-rending calculation—how far is the distant feeding center and how close is the nearest well?
Landsat plays a key role in reducing hunger on earth
The United Nations’ Department of Economic and Social Affairs predicts 9.7 billion people will sit down every day to the global dinner table by 2050. If this prediction is correct, the world is going to need more crops, more livestock, and more efficient and sustainable agricultural practices.
