"Will continue support for the Landsat Data Continuity Mission, which allows study of the earth's land surfaces and provides valuable data for agricultural, educational, scientific, and government use."
Landsat is a satellite program, jointly run by NASA and the U.S. Geological Survey, that has been used for climate research, natural resources management, land development, public safety, homeland security and disaster recovery. It has operated for more than 25 years, with two satellites — Landsat-5, launched in 1984, and Landsat-7, launched in 1999 — still in orbit. But they are operating beyond their planned life and are subject to failure.
To ensure that the program survives, NASA and USGS are developing the Landsat Data Continuity Mission, or LDCM, which is planning to launch a spacecraft in December 2012, according to the Congressional Research Service.
In its fiscal year 2010 proposed budget, the Obama administration sought $120.6 million for LDCM through NASA accounts and $40.2 million through USGS accounts. Between July 14, 2009, and July 17, 2009, a preliminary design review was held in Linthicum, Md. NASA described the event as "successful" — an early milestone for the program.
LDCM won't be ready to launch for a few years, but the promise was simply to "support" the program. The Obama administration has done that, seeking funding for it. We consider it a Promise Kept.
