LDCM Subsystems

Integration

OLI Telescope
LDCM Family Portrait
03.08.12 - Both Landsat Data Continuity Mission (LDCM) instruments have been mounted to the spacecraft at Orbital Science Corp. in Gilbert Arizona.

Operational Land Imager (OLI)

OLI Telescope
Operational Land Imager (OLI) Integration
10.18.11 - Engineers at Orbital Sciences Corporation, Gilbert, AZ mechanically integrated the Operational Land Imager (OLI) onto the Landsat Data Continuity Mission (LDCM) spacecraft.
OLI Telescope
LDCM Operational Land Imager (OLI)—VIS/IR Instrument
07.08.11 - OLI improves on past Landsat sensors using a technical approach demonstrated by a sensor flown on NASA's experimental EO-1 satellite.
OLI Telescope
The Calibration Subsystem for LDCM's Operational Land Imager
07.01.11 - The Calibration Subsystem for the Operational Land Imager (OLI) on LDCM uses both the sun and the absence of light to establish the light and dark end points, respectively, of a scale used to interpret the collected reflectance data.
OLI Telescope
Operational Land Imager (OLI) Telescope
06.20.11 - The OLI telescope uses a four-mirror compact design. The optics are positioned inside a lightweight, yet highly stable, carbon composite optical bench.

Thermal Infrared Sensor (TIRS)

OLI Telescope
The Cryocooler—Part of the LDCM Thermal Infrared Sensor (TIRS)
06.20.11 - The Cryocooler is like a big refrigerator, except that it cools to cryogenic temperatures (below −150°C, −238°F or 123K).
OLI Telescope
Meet the "Scene Select Mechanism"—Part of the LDCM Thermal Infrared Sensor
06.14.11 - The Scene Select Mechanism is an apparatus that rotates the LDCM Thermal Infrared Sensor (TIRS) mirror among three scenes: the Earth view ("nadir;" when imaging the Earth), and two calibration views (one of a warm blackbody carried onboard and the other of a deep-space cold view).
OLI Telescope
The Calibration Ground Support Equipment (GSE) —Part of the LDCM Thermal Infrared Sensor (TIRS)
06.14.11 - This is used to test and characterize the Thermal Infrared Sensor (TIRS) instrument

USGS Landsat

USGS LDCM website
The Landsat Program is a series of Earth-observing satellite missions jointly managed by NASA and the U.S. Geological Survey. Since 1972, Landsat satellites have collected information about Earth from space. This science, known as remote sensing, has matured with the Landsat Program.

Landsat Education

Landsat Education website
By virtue of its long history, Landsat's education and outreach program has spawned many educational resources. The effort continues with what will be the newest in this series of satellites, the Landsat Data Continuity Mission (LDCM). To enable educators seamless access to all of these resources, Landsat and LDCM education are united into one program.
