Optical Properties Monitor (OPM)

OPM and the Space Portable SpectroReflectometer (SPSR) were developed under the protoflight concept in partnership with NASA, flown aboard the Space Shuttle and used on the exterior of the Russian Mir Space Station. The OPM was placed on the exterior of MIR during the first joint US/Russian spacewalk. These very successful programs included design, development testing, and verification of this hardware and included integrating the requirements for hardware performance, Shuttle, SpaceHab, and Mir payloads, and Extravehicular Activities (EVA) while maintaining a cost-effective program. Data from OPM and SPSR are still being used today (See System Report (pdf 12 MB) and Science Report (pdf 16MB) for detailed reports). The need to monitor the optical properties of materials in space is still very important. AZ Technology continues to be involved with experiments on Materials International Space Station Experiment (MISSE). See also MISSE Summary Report (pdf 540KB).

What does a "materials exposure experiment" do? The obvious answer is that it exposes materials to space. But the OPM did much more than that. It had the capability to take measurements on the materials being exposed while they were still out in the space vacuum, without having to bring them back to Earth and risk their being contaminated by handling and exposure to atmosphere and gravity.

The OPM monitored the space environment in its vicinity, so it could ascertain what the samples were actually being exposed to. And it had the ability to be controlled from Earth, so that the experiment could be changed on the fly when unusual results were seen. From April to December 1997, the OPM, in its position on the outside of the Mir's Space Shuttle docking module, monitored the space environment around Mir and took measurements on material samples.
