When landed on the moon, the ladder seems to be in the shadow for each Apollo mission.
For example, on this photo, the ladder is not in the side exposed to the Sun. (the astronaut go out of the LM in the shadow of the LM).
Why did the NASA choose to land the LEM in that direction (exit (and the ladder) in the shadow of the LM)?

All the lunar landings were performed with the sun low in the sky behind the LM, between 5º and 14º above the horizon at the landing site. This provided several advantages:
- The sun wouldn't be in the crew’s eyes during any portion of the descent (they’d start out oriented feet forward, lying on their backs looking upward, during the braking phase, and progressively pitch downward from that orientation to standing vertically looking forward during the final portion of descent)
- The terrain would cast sharp shadows, which made it easier to see the shape of the surface
- The shadow of the LM itself would be cast on the ground ahead in the final moments of descent, which would help the commander judge the LM's altitude.
The descent ladder, being on the front leg of the ship, was therefore always in shadow after touchdown.
