     Spacecraft Components

ASR is currently working on the mechanical design of a methanol far infrared laser local oscillator (LLO) module for the Earth Observing System (EOS) portion of NASA's Mission to Planet Earth (MTPE) program.

The Jet Propulsion Laboratory of the California Institute of Technology has awarded the development of the LLO module to Coherent-DEOS. As subcontractor to DEOS, ASR is responsible for the mechanical engineering aspect of the program, which includes design, stress and thermal analysis and drafting.

The EOS portion of NASA's MTPE program includes space instrumentation directed toward understanding the chemistry of the Earth's atmosphere from space. The methanol LLO will be part of the Microwave Limb Sounder portion of the EOS Aura satellite program which will be responsible for acquiring OH atmospheric data, as well as other data, by looking through the atmosphere "limb" from space. Understanding the role of the OH molecule in the Earth's atmospheric chemistry is important in predicting future trends in the ozone layer.

From conceptual design through detail design and analytical simulation of launch loads and thermal conditions, ASR can substantially increase your chances for success.

JPL awarded ASR the mechanical design and structural/thermal analysis responsibility for the secondary and tertiary mirrors of the Cloudsat spacecraft.
