Vibration

To determine structural stability before instruments and components are flown, it is important to perform tests that simulate vibration and shock equivalent to the actual operational environment. SDL has over 50 years of experience testing systems and components for space and upper atmospheric environments and uses a UDC SAI 160F-R24C/ST vibration test system designed to provide reliable performance for medium and high force applications.

Experience

OSIRIS-Rex

Origins Spectral Interpretation Resource Identification Security Regolith Explorer

OSIRIS REx is a NASA New Frontiers mission to return a sample of an asteroid to the Earth. SDL is designing, building, and testing the detector electronics assemblies for the three OSIRIS-REx Camera Suite (OCAM) instruments.

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.

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.

JWST Heat Switch

James Webb Space Telescope

SDL designed and demonstrated an advanced thermal switch for NASA’s Goddard Space Flight Center (GSFC) James Webb Space Telescope (JWST).

JWST Thermal Links

James Webb Space Telescope

SDL developed thermal links to transport heat from JWST’s science instruments to their radiators, enabling each instrument to operate at desired temperatures.

GIFTS

Geosynchronous Imaging Fourier Transform Spectrometer

GIFTS was successfully tested and calibrated as an engineering demonstration unit to ground-validate technologies critical to NOAA’s Hyperspectral Environmental Suite for the Geostationary Operational Environmental Satellite (GOES) system.

FPMU

Floating Potential Measurement Unit

The FPMU is an important diagnostic tool that helps enable NASA to monitor and control surface charging on the International Space Station, reducing risks to astronauts during extra-vehicular activity.
