Comet surface changes before Rosetta’s eyes | Rosetta - ESA's comet chaser

Since arriving at Comet 67P/C-G in August 2014, Rosetta has been witnessing an increase in the activity of the comet, warmed by the ever-closer Sun. A general increase in the outflow of gas and dust has been punctuated by the emergence of jets and dramatic rapid outbursts in the weeks around perihelion, the closest point to the Sun on the comet’s orbit, which occurred on 13 August 2015.

But in June 2015, just two months before perihelion, Rosetta scientists started noticing important changes on the surface of the nucleus itself. These very significant alterations have been seen in Imhotep, a region containing smooth terrains covered by fine-grained material as well as large boulders, located on 67P/C-G’s large lobe.

"We did not expect to find hints of a nitrogen-based glacial cycle on Pluto operating in the frigid conditions of the outer solar system,” said Alan Howard, a member of the mission’s Geology, Geophysics and Imaging team from the University of Virginia, Charlottesville. “Driven by dim sunlight, this would be directly comparable to the hydrological cycle that feeds ice caps on Earth, where water is evaporated from the oceans, falls as snow, and returns to the seas through glacial flow.”

“Pluto is surprisingly Earth-like in this regard,” added Stern, “and no one predicted it.”

KOCOURMIKES: ano, pokud budu tavit tuny. Pokud budu tavit 5g, staci mi tuzkova baterie. Zaver je, ze z maleho solarniho panelu (nebo radioizotopoveho zdroje) budu vyrabet dost kysliku pro jednoho cloveka, navic kovy a CO2 budu vypoustet do atmosfery marsu.
Jinak doporucuji koupit si nejakou ucebnici fyziky pro zakladni skoly treba..

KOCOURMIKES: "An industrial-scale smelter" - to znamena neco, co produkuje tuny hliniku kazdy den. Ten proud nema s principem nic spolecneho, jenom s tim "industrialnim" meritkem. Podobne by nekdo mohl argumentovat, ze nemuzou fungovat domaci kaminka na koks s malou hromadkou ve sklepe, kdyz teplarna spotrebuje 20 tun koksu denne.. napr.
Principialne bude ta vyroba kysliku z oxidu fungovat i s nekolika malo ampery. Jde jen o meritko.
