On the Moon, knowing when the Sun is visible means access to power and navigation.  This solution module of MoonHacker™ from Lunar Station™ gives you the insights needed about the Sun's surface illumination or energy flux for any location so that your mission can succeed.  Just order this and we will produce the numpy file format chart(s) for you!  We will send you an email to receive your site coordinates (lat/lon), starting date (mm/dd/yy) and the ending date (mm/dd/yy) of your time on the surface.  You will see the Sun's availability for your site with binary blocks of light/no-light map(s). 
Basic map uses USGS 30 meter Tiff DEM with 1km squared area and 1 meter resolution for mapping for single point-in-time.  If you want more maps (1 per hour over a period of time: increase the quantity for the period of time).
You can order time series maps by the number of hours needed to support your mission planning. 
Notes: 1) Screenshot shows larger area of mapping with lower resolution. 2) If you want to customize this mapping order with larger areas and/or higher resolution DEMs - contact us!
