Milan A. Nikolic ::Koridor ::Habl snima vise u Infracrvenom spektru nego optickom ali nevtreba ti Habl da snimi boju gaca na striku ispred kuce (pogledaj Google Earth) to dobro rade svi komercijalni sateliti samo se placa...

Реч је била о сателиту који би непрекидно снимао једну тачку земље, што не могу да чине сателити у нижој орбити. Зато питам, какву слику у смислу употребљивости би дао свемирски телескоп попут Хабла са даљине геостационарне орбите? Стварно бих волео да то неко израчуна и покаже.

Милане,
ако имаш сателит на 500км и на 35000км, односно 70 пута већем одстојању, проста математика показује да ће бити потребно огледало 70х већег пречника да би прикупио исту количину светла са једног места.

Комерцијални сателит који користи Максар има резолуцију од 41цм, а лети на висини од 680км. Величина огледала је 1,1 метар.
