Hey folks, I browsed "Hipparchus" site:ntrs.nasa.gov on google, and guess what I found ? A Surveyor landing site at Hipparchus !
In a Lunar Orbiter V mission report - attached.
Thanks to [USER=960]@Justo Miranda[/USER] artwork and the french book I mentionned, I managed to pinpoint both landing spots on LROC map.
Hipparchus X for Tintin versus Surveyor coordinates.
So, behold: Tintin versus Surveyor at Hipparchus. Pink cross is Hipparchus X, with coordinates at the bottom; blue dot is Surveoyor landing spot coordinates (on top, according to the attached pdf.)
Hipparchus X: 3.80° S 3.40° E
Surveyor spot: 4.45°S 4.05° E
Lunar circumference is 11000 km, divided by 360 degrees: 1 lunar degree is roughly 31 km. Hence, 0.5 degree should be 15 km.
So both places are merely 20 km apart.
