The mod Science Arkive informs me that there are several regions on the Mun that have not been logged yet. Craters, Mare Eye, and several ???? which represent discoverables such as the Mun Arches. For this mission, I am going after the Mare Eye.
What is a Mare Eye?
Two mare on the Mun, Mare Chorum (the Northwest Mare) and Mare Tergus (Farside Mare) have bright areas in there centers. The impacts that made them happened in stages. The first was impact and compression where the asteroid slams into the rock, transferring that kinetic energy to that rock. The next part is that rock being pushed out by that energy into a crater. Finally, gravity is able to pull some of that material back down. In a smaller crater, most of the material has been thrown away and you have a clean bowl-shaped crater, but larger impacts attempting to excavate more material has a lot more rock that doesn’t make it out of the crater. Gravity pulls it back and it can slide down the crater rim towards the center, run into other material sliding down the other side of the crater, and splash upwards, forming a central peak. In these particularly large impacts that punch through the crust, the molten mantel beneath is no longer being held down by the weight of the crust above it and it rises to fill in the space, again, pushing that central peak up. This peak is not covered by the subsequent molten rock flow and so is lighter.
Mission Designation : LN-3
Rocket Model : Lunaria UL-II
Total delta-V (to orbit) : 8,842 m/s (4,013 m/s)
Surface TWR : 1.20
Total Mass (to orbit) : 184.07 t (30.46 t)
Dry Mass : 37.93 t
Part Count : 62
Height : 23.79 m
Width : 7.99 m
Length : 3.96 m
Mission Objectives : Land at a mare eye
Crew : Huduki Kerman, Erbart Kerman, Lanory Kerman
Into orbit of the Mun had be on almost exactly the right trajectory to come around the other side and land at Mare Tergus.
After having collected the science at the mare, I wanted to make another attempt to hop to a Crater region. There was a large crater to the northeast that looked promising and the craft had 2,45 m/s of delta-V available.
But on the ascent, I wasn’t seeing the path in map view. A repeat of a glitch. Without that path, I would have a hard time figuring out where I was landing, and so I abandoned the project and burned to Munar orbit.
After getting into orbit, I saw that the glitch had repaired itself and I could see the path again. Doing a hop had been well within my delta-V reserves but I didn’t want to push my luck with a full-on deorbit, descent, and landing.
