The unmanned craft was due to make a soft landing on the Moon's south pole, but failed after encountering issues as it moved into its pre-landing orbit.

It was Russia's first Moon mission in almost 50 years.

The spacecraft was scheduled to land on Monday to explore a part of the Moon which scientists think could hold frozen water and precious elements.

Roskosmos, Russia's state space corporation, said it lost contact with the Luna-25 shortly after running into difficulties.

Mainly, because the poles are always just barely within line of sight to Earth (and thus line of communications) if at all. So the probe has to either operate autonomously or you have to maintain coms via a relay satellite. Either isn't exactly easy with hardware that must also be radiation-hardened and lightweight. Initiating the deorbit burn should (I am guessing this) be done from the backside or you'll run into even more problems when you overshoot the landing site.

Thanks for sharing. That all makes sense.
