Q: Would someone be so kind as to convert what is meant in the Users Guide "Mission lifetime: Lunar mid-morning to Lunar noon." primary mission duration into Earth minutes please.

A: The assumption is that the CLPS landers will land on the surface after the sun is high enough above the lunar horizon to provide good illumination on the solar panels (hence mid-morning) and the mission will end at some point after the lander power is exhausted when the sun has set. A full “lunar day” is a bit over 27 earth days so the period when the landing site is illuminated is a bit over two weeks or 14 Earth days. Things like the latitude of the landing site and elevation of the lander affect this so there will be a fair amount of variance. The actual landing time into the lunar day cannot be predicted with certainty since there are a lot of orbital mechanics involved with getting there and it is highly dependent on the launch vehicle used. The payload provider can make some assumptions and do a simple calculation to determine the number of minutes based on those assumptions.
