Committee on Implementation of a Sustained Land Imaging Program; Space Studies Board; Division on Engineering and Physical Sciences; National Research Council
In 1972 NASA launched the Earth Resources Technology Satellite (ETRS), now known as Landsat 1, and on February 11, 2013 launched Landsat 8. Currently the United States has collected 40 continuous years of satellite records of land remote sensing data from satellites similar to these. Even though this data is valuable to improving many different aspects of the country such as agriculture, homeland security, and disaster mitigation; the availability of this data for planning our nation’s future is at risk.
Thus, the Department of the Interior’s (DOI’s) U.S. Geological Survey (USGS) requested that the National Research Council’s (NRC’s) Committee on Implementation of a Sustained Land Imaging Program review the needs and opportunities necessary for the development of a national space-based operational land imaging capability. The committee was specifically tasked with several objectives including identifying stakeholders and their data needs and providing recommendations to facilitate the transition from NASA’s research-based series of satellites to a sustained USGS land imaging program.
Landsat and Beyond: Sustaining and Enhancing the Nation’s Land Imaging Program is the result of the committee’s investigation. This investigation included meetings with stakeholders such as the DOI, NASA, NOAA, and commercial data providers. The report includes the committee’s recommendations, information about different aspects of the program, and a section dedicated to future opportunities.
Earth observation is a science and technology with tremendous power to collect data over the whole of the Earth at many wavelengths and at many spatial resolutions. But does this science and technology, or rather the use of this science and technology, have an ethical dimension? This article explores the application of ethical concepts to Earth observation. Three main aspects of ethics are examined: duty theories of ethics, consequentialist ethics, and environmental ethics. These ethical ideas are then applied to the UN Principles on Remote Sensing, the International Charter on Space and Major Disasters and to Google Earth, and also to questions of security and privacy. The article concludes that there is no absolute ethical position in relation to Earth observation, but a dependency on the perspective of the observer.

The eighth satellite in NASA’s Earth-watching Landsat fleet will launch Monday, Feb. 11 from Vandenberg Air Force Base in California…. The joint program between NASA and the U.S. Geological Survey is the longest-running data record of Earth observations from space. …The Landsat program enables scientists to track major changes of Earth’s surface, including melting glaciers, urban explosion and the effects of natural disasters.

The U.S. Geological Survey (USGS) injected a bit of life into its aging Landsat 5 satellite, which has orbited Earth more than 150,000 times since its launch in 1984 and has been experiencing problems with its thematic mapper (TM) instrument. Engineers have been able to power-on a long-dormant data-collection instrument aboard the satellite—the multispectral scanner (MSS), which has been offline for more than a decade. USGS now is acquiring MSS data over the United States only. The news is significant, because USGS continues to work toward launch of an eighth Landsat satellite, meaning that data from current Landsat craft still are key to Earth-observing operations. Landsat 7, activated in 1999, continues to collect images worldwide. But, in 2003, Landsat 7 experienced a hardware failure that caused a 22-percent loss of data in every image. Meanwhile, the Landsat Data Continuity Mission (LDCM or Landsat 8), is scheduled for launch in January 2013.

U.S. government agencies are working together to look for ways to reduce the cost of future Landsat missions as a result of congressional direction included in the 2012 budget passed in December. “Although Congress has provided $2 million to the U.S. Geological Service for Landsat 9 program development, they have also requested that the Administration re-examine how to proceed with future Landsat missions,” Jon Campbell, spokesman for the Interior Department’s U.S. Geological Survey (USGS), said in a Jan. 10 email. … U.S. President Barack Obama requested $48 million for USGS to pave the way for development of Landsat 9 and Landsat 10, spacecraft designed to extend the Landsat program’s 40-year record of providing moderate-resolution imagery on global agriculture, land use and natural disasters. …
