Antarctica is in the middle of winter right now, which usually means scientists stationed there are stranded for all but the most dire of emergencies. Evidently, one of those emergencies is occurring now, and a rescue is presently underway. The Amundsen-Scott research station opened in 1957, and this is only the third time a winter rescue has been attempted. Wired gives a good summary of the problem:

There are also no paved runways. There is only ice, as far as the eye can see. Actually, the ice stretches far beyond what the eye can see. The Antarctic ice sheet is about one and a half times the size of the continental United States, and it’s more than 9,000 feet thick at the pole. The plane needs to land on the ice and snow itself—with skis.
