NASA is gearing up for the Monday launch of an Earth-observation satellite that will continue a celebrated 40-year project to monitor our planet's surface from space. <\/p>\n
The Landsat Data Continuity Mission is slated to blast off Monday at 1:02 p.m. EST (1802 GMT\/10:02 a.m. PST) from Vandenberg Air Force Base in California. The LDCM satellite is the eighth overall in the Landsat program, which has been scrutinizing Earth from orbit continuously since Landsat 1 launched in 1972. <\/p>\n
Mission team members call LDCM the most advanced and capable Landsat spacecraft ever built. It should help the United States and other nations around the world monitor environmental change and better manage their natural resources, they say. <\/p>\n
\"LDCM will continue to describe the human impact on Earth and the impact of Earth on humanity, which is vital for accommodating seven billion people on our planet,\" LDCM project manager Ken Schwer, of NASA's Goddard Space Flight Center in Greenbelt, Md., told reporters Friday during a prelaunch press briefing.

The $855 million LDCM mission is a collaboration between NASA and the United States Geological Survey, which will take over operations after the spacecraft's launch and initial checkouts. At that point, the satellite will be renamed Landsat 8. <\/p>\n
Landsat 8 will zip around the Earth at an altitude of 438 miles, using two sensors to study the planet's surface in the visible and infrared portions of the electromagnetic spectrum. <\/p>\n
The SUV-size satellite will achieve full Earth coverage every 16 days, though its work will lower this to once per eight days for the program overall. That's because Landsat 8 will fly eight days behind Landsat 7, which launched in 1999 and recently became the only currently operational Landsat spacecraft. (Landsat 5 retiredrecently after 29 years of service). <\/p>\n
