Thermal & Structural Management

Because electronic and instrument components are very sensitive to stresses that occur in the operational environment, including temperature extremes and launch loads, thermal and structural management are critical to mission success. SDL has extensive experience in thermal and structural management and our onsite testing facilities enable rapid analysis.

Experience

WISE

Wide-field Infrared Survey Explorer

The WISE cryogenically-cooled infrared telescope provided a complete stellar infrared map more than 1,000 times more detailed than previous surveys.

SABER

Sounding of the Atmosphere using Broadband Emission Radiometry

SABER, a 10-channel infrared (1.27 to 16.9 µm) radiometer, is one of four instruments on NASA's TIMED mission, which is dedicated to study the dynamics of the Mesosphere and Lower Thermosphere (MLT) portion of the Earth's atmosphere.

ASSP

Auroral Spatial Structures Probe

ASSP was designed to measure the spatial and temporal variation of the energy flow in the upper atmosphere in and around the aurora to better understand global temperature changes in the thermosphere.

AIM/SOFIE

Aeronomy of Ice in the Mesosphere Solar Occultation for Ice Experiment

SOFIE is one of three instruments aboard the Aeronomy of Ice in the Mesosphere (AIM) satellite. AIM’s objective is to study polar mesospheric clouds and the environment in which they form.

RASAR

Real-time, Autonomous, Synthetic Aperture Radar

RASAR is a full-featured, flight-proven, 25-lb radar system with expandable capabilities that include dual-band operation, ground moving target indicator (GMTI), and comprehensive data processing and image formation capabilities.

DICE

Dynamic Ionosphere Cubesat Experiment

Twin CubeSats mapped the geomagnetic Storm Enhanced Density (SED) plasma bulge and plume formations in Earth’s ionosphere.
