Not yet, there's barely snow on the ground in the Arctic Circle right now, not much below freezing overnight. Give it another month, then we're talking.

- gojomo 3y agoSeems to me that soon as there are consistent nighttime freezes, pumped water could create a level & sealed frozen surface.
- lxgr 3y agoInteresting question: Can a jet take off from a (very) low friction runway? Seems similar to the classical problem of whether a take-off from a conveyor belt is possible :)

- lxgr 3y agoThat runway has been carefully prepared to have high friction: > The original construction of the runway was done over two years and accomplished using a laser cutter to level the blue ice near the station [...] Finally, two snow groomers with tillers grind a small layer of ice to create a top layer of crushed snow and ice that gives the runway the necessary friction for aircraft to operate. https://www.flightradar24.com/blog/troll-research-station-how-to-operate-an-airport-in-antarctica/ https://www.flightradar24.com/blog/troll-research-station-ho...

- grecy 3y agoYou'd be surprised, even +5C during the day will turn that shallow frozen water back to liquid. But when it hits, it happens quickly. Every year people dogsled on a lake outside Whitehorse, Yukon in November. Often it's pure liquid on November 20th, and yet they will dogsled on it before the last day of the month.
