Water Impact Simulation Ensures Safer Landing for NASA Astronauts

The water landing of a craft like the Orion Crew Module is a very complex and changeable event, subject to the dynamics of the vehicle’s structure and sub-structures, such as its heat shield and atmospheric and water conditions. To maintain the spacecraft’s structural integrity and increase safety of the crew, a clearer understanding of the dynamic loads generated during water impact was required.

Demystifying Spectroscopy

Spectroscopy techniques date back to Isaac Newton’s first studies of light and today provide researchers with a better understanding of what happens at the atomic and molecular level when matter interacts with light. Advances in electro-optics, high-speed array detectors, inexpensive optical fibers and powerful computers have spurred the growth of miniature spectroscopy. This miniaturization has increasingly made optical spectroscopy the sensing technique of choice for many real-world applications.

System-on-Module for Pre-Packaged Convenience

Increasing design complexity, coupled with compressed time to market, has been an engineering reality for some time. A system-on-module (SOM) addresses both of these real engineering issues. An engineer who chooses to use a SOM trades a very complex, chip-down circuit design for a much simpler SOM connector interface.

Measuring Motion with Imaging Software

High-speed photography is as much of an engineering tool as an oscilloscope, spectrum analyzer, or logic analyzer. The photographic technique enables us to visualize and analyze motion, especially motion that is too fast for the human eye or conventional cameras to perceive.
