Editing MMR06

{{Short description|Soviet sounding rocket}}
{{Expand Russian}}
The '''MMR06''' is a Soviet/Russian [[rocket]] for [[meteorological]] experiments, with a length of 3.48 metres and a total weight of 130&nbsp;kg. The MMR06 rocket was built in two versions: One version had a [[cone (geometry)|conical]] top, the second one, named MMR06-M, had a detachable free flying top, also called [[dart (rocket)|dart]]. The maximum flight height was about 60 - 80 kilometres. Between 1988 and 1992 62 rockets of the type MMR06-M were launched from the former [[Nationale Volksarmee|NVA]] exercise area [[Zingst]], in order to accomplish wind and temperature measurements in the upper [[Earth's atmosphere|atmosphere]].
