The objective of the MEO is to understand the flux and the associated risk of meteoroids impacting spacecraft traveling in and beyond Earth’s orbit. Meteoroids impacting spacecraft are a quantifiable risk as they can puncture pressurized volumes (i.e. space station modules, propellant tanks) or destroy components (i.e. engines, electronics). While meteoroids have never been definitively proven to have destroyed a spacecraft, there have been several in-flight anomalies attributed to meteoroid impacts including loss of the Olympus satellite to control system failure induced by a Perseid shower meteor impact. Understanding the meteoroid environment can help spacecraft designers to better protect critical components on spacecraft or avoid critical operations such as extravehicular activities during periods of higher flux such as meteor showers..
