MIR Environmental Effects Payload
(MEEP) Archive System

NASA Langley Research Center
Hampton, Virginia

The Mir Environmental Effects Payload (MEEP) was an International Space Station Phase 1 Risk Mitigation Experiment that will provide an assessment of baseline and candidate Space Station materials for the intended operational environment of the International Space Station. MEEP also fulfill the need to examine the occurrence and effects of man-made debris and natural micrometeoroids through capture and impact studies. The MEEP was deployed on the Mir/Shuttle Docking Module via an Extravehicular Activity (EVA) from the shuttle on STS-76, and was retrieved during STS-86.

MEEP consists of a family of four science experiments that are deployed on a common carrier. Langley Research center has the overall responsibility for the MEEP experiment as well as the development of the common carrier. The organizations responsible for each of the science experiments are listed in the descriptions below pertaining to each of the four experiments.

• Passive Experiment Carrier (PEC)
• Polished Plate Micrometeoroid and Debris (PPMD)
• Passive Optical Sample Assembly I (POSA I)
• Orbital Debris Collector (ODC)
• Passive Optical Sample Assembly II (POSA II)
