There is a very nice map of the mission. https://mars.nasa.gov/maps/location/?mission=M20 https://mars.nasa.gov/maps/location/?mission=M20 If you go to layers you can turn on the helicopter flight path. The only thing I was missing was a distance tool. But while I was looking for that I did find two hidden tools which sort of work for distances. drag the scale marker in the bottom left corner to get a rectangle widget you can place on the map. click on the lat/log in the lower right side to cycle to easting/northing and relative east/north.
