The instrument control electronics (ICE) moves the filter wheel when commanded by the MIRI flight software (FSW). The ICE can measure the absolute position of the filter wheel before and/or after movement of the filter wheel. The ICE can move the filter wheel to the next adjacent position in either direction. ... Broad Band . ...

... Comets and Asteroids . ... In May 2014 Rosetta started to apply the brakes with its thrusters so the ten year mission would not end up with Rosetta scorching past the comet and instead find itself sharing the comet?s orbit. ... As stated above scientists believed that comet 67P was going to a glorious BRIGHT ball of ice due to the fact that it is not close enough to the warmer regions of the solar system to start melting but alas it is duller than a rock!

... The scale is 1 00 per pixel, with sky coverage of more than 4 0 2 4 0 on the NICMOS 3 (256 2 256 pixels, 40 Їm side) detector array. The optical path is compact enough to be enclosed in a 25.4 cm diameter dewar; the working temperature is 76 K. The camera is remotely controlled by a 486 PC, connected to the array control electronics via a fiber--optics link. A C--language package, running under MS--DOS on the 486 PC, acquires and stores the frames, and controls the timing of the array. ...
