CNC Machining of Lightweight Mirrors for a High Resolution Science Experiment Camera
( Click image to enlarge )
At Pacific Quartz, Inc., our portfolio of skills gives us the opportunity to participate in some high profile projects that demand nothing short of perfection. We built the lightweight mirrors shown here for the High Resolution Imaging Science Experiment (HiRISE) camera on the Mars Reconnaissance Orbiter spacecraft. Launched in 2005, it was the largest reflecting telescope carried on a deep space mission, and has continued to provide NASA scientists with stunning visuals of the Martian landscape.
This project was challenging, but since we had done other projects for this client, they knew they could trust us to deliver on quality. As a NASA project it was subject to a process qualification program—all manufacturing equipment, tooling, and instrumentation used to assess, measure, or make contact with the product had to be qualified using defined validation protocols. We worked closely with the customer on design and machinability issues, but the dynamics of the project required the client to make modifications to the original model after the job was in process. Our agility enabled us to react quickly adjust what was necessary to keep the project on track.
We wound up delivering two sets of low expansion ceramic glass mirrors to the client within an 8 week timeframe, enabling them to meet their project deadlines. These mirrors are now in orbit millions of miles from Earth, and the telescope continues to provide rich information about our neighboring planet.
