TIRS telescope
Jun 27, 2013Spectral Response of the Thermal Infrared Sensor

< TIRS Design   In-Band, Band-Average Relative Spectral Response The band-average relative spectral radiance responses of the Thermal Infrared Sensor (TIRS) are provided here. These responses are based on measurements of the individual Read [...]

TIRS cryocooler
Jun 27, 2013TIRS Design

< TIRS Requirements TIRS Relative Spectral Response >   Like OLI, TIRS is also a push broom sensor employing a focal plane with long arrays of photosensitive detectors (Fig. 6). A four-element refractive telescope focuses an f/1.64 Read [...]

Jun 27, 2013TIRS Requirements

< Thermal Infrared Sensor TIRS Design >   TIRS requirements are specified in a manner similar to the OLI requirements. The specifications require TIRS to collect image data for two thermal infrared spectral bands with a spatial resolution [...]

launch vehicle assembly
Jun 19, 2013Launch Vehicle

The LDCM observatory will launch from Space Launch Complex-3E at Vandenberg Air Force Base aboard an Atlas V 401 launch vehicle built by the United Launch Alliance (ULA). This rocket is an evolved expendable launch vehicle capable of placing a [...]

Thermal Infrared Sensor (TIRS)
Jun 19, 2013Thermal Infrared Sensor (TIRS)

TIRS Requirements > The Thermal Infrared Sensor (TIRS) will measure land surface temperature in two thermal bands with a new technology that applies quantum physics to detect heat. TIRS was added to the satellite mission when it became clear [...]

Operational Land Imager (OLI)
Jun 19, 2013Operational Land Imager (OLI)

OLI Requirements > The Operational Land Imager (OLI), built by the Ball Aerospace & Technologies Corporation, will measure in the visible, near infrared, and short wave infrared portions of the spectrum. Its images will have 15-meter (49 [...]

Spacecraft Design
Jun 19, 2013Spacecraft Design

< Spacecraft   The spacecraft will supply power, orbit and attitude control, communications, and data storage for OLI and TIRS. The spacecraft consists of the mechanical subsystem (primary structure and deployable mechanisms), command and [...]

Landsat 8 spacecraft
Jun 14, 2013Spacecraft

Spacecraft Design > Landsat 8 consist of two major segments: the observatory and the ground system. The observatory consists of the spacecraft bus and its payload of two Earth observing sensors, the Operational Land Imager (OLI) and the Thermal [...]

May 15, 2013New Animation Marks Arrival of NASA’s LDCM Satellite to its Final Orbit

Have you ever wondered what it might be like to watch the world fly by beneath you from space? That dream is elusive for most of us, but the Landsat Data Continuity Mission offers a vicarious flight with a crisper view than our eyes alone would [...]
