Oceanus Procellarum

Like other lunar pits, MHP will serve as an opening to these underground spaces which may have formed during ancient volcanic activity.

One in particular is the Marius Hill Pit, MHP, a prominent skylight on the near side's Oceanus Procellarum.

Gimli will allow scientists to investigate MHP directly from the lunar surface using an advanced suite of instruments.

These include ground-penetrating radar, seismic sensors, a gravimeter to probe beneath the surface, and cameras that provide imagery of the surface and pit walls.

We are heading to a highly specific location called the Marius Hills Pit, or MHP.

Right, in the Oceanus Procellarum.

Yeah, which is one of the Moon's most volcanically diverse regions.

And just to be clear, this isn't, you know, a standard impact crater.

They're really cool.

Day 26, the illuminated area shrinks rapidly, shifting in focus across the western edges of the Oceanus Procellarum vast southern crater fields, mainly all that kind of rough terrain.

Your targets are getting fewer in choice, but still spectacular.

Schickard Crater is a massive flat-floored walled plain near the eastern limb, showing dark basaltic patches on its floor.

it is cute.

So look for Grimaldi Crater, which is one of the darkest spots on the Moon, appearing as a dark oval near the extreme limb, sharply contrasting with the bright surrounding highlands.

And then the Oceanus Procellarum is heavily foreshortened by perspective near the edge now as the g- like, just the very western edge of it, giving a sort of unique visual depth to it, which is really cool.

Yeah.
