The LTV is orbiting the moon, waiting to bring our crew back to Earth at the end of the mission. If you look closely, you can see the third crewmember checking out the Ascent Stage, making sure it will be ready at a moment's notice to carry the crew to lunar orbit. As you move around toward toward the southwest, the airlock comes into view. This T-shaped vestibule is the front door to the habitat. The hatch on the end was docked to the Lunar Transfer Vehicle during the trip out from Earth.
Light glinting off the airlock window is a reflection of the mountains around Angus Bay.
On the moon, our crewmembers will use the side hatch to enter and leave the lunar exploration base. Moving around the airlock, back toward the front of the base, you can see the lightweight stairs that the crew have erected in front of the airlock. If we land at Angus Bay , the sun won't be that far north. The orientation of the earth and the sun in the sky is closer to the view we'd get if we land near the equator at Mare Marginis or Mare Smythii. The region around Angus Bay will probably have more hills, rilles, and rocks than we're showing in these views.
