Nettstedet Reddit (hva, er du ikke der forlengst?) holder jevnlig “Ask Me Anything”-sesjoner, som har fått så høy status etterhvert at også president Obama har stilt opp. Igår var det hovedforsker i New Horizons-prosjektet Alan Sterns tur, og han fikk mange og gode spørsmål. Vi har samlet de beste nedenfor.
What has surprised you the most in the data that you’ve gathered so far?
For me, Charon’s dark pole. We all think this is hysterical, because Charon had a dark pole in the simulation we did of what the encounter would be like. It was also a surprise because Charon’s rotational light curve (i.e. its pattern of light and dark) is very subtle, so while we knew Pluto was going to have dark spots, Charon very well could have been uniform.
