ZZ-ZZ-ZZ-ZZ-20100727_LORRILooksBack_lg.jpgOn the Way to Pluto: Jupiter, Europa and Ganymede102 visiteCaption NASA:"New Horizons had an exciting Fly-By encounter with Jupiter in early 2007, and the Spacecraft has been rapidly moving away from the Giant Planet ever since.
The New Horizons team looked back at Jupiter during Annual Checkout (ACO) to test the Long Range Reconnaissance Imager (LORRI)'s ability to image targets close, in angle, to the Sun.
This image was taken on June 24, 2010, when New Horizons was 16,3 Astronomical Units (about 1,5 Billion Miles) from Jupiter, at a Spacecraft-Sun-Planet angle of only 17°. Looking like Earth's moon at a quarter phase, Jupiter is clearly resolved, with an apparent diameter of nearly 12 LORRI pixels. LORRI also picks up the moons Ganymede and Europa, even though the exposure time was only 9 milliseconds and these Galilean satellites are extremely faint in comparison to Jupiter".MareKromium

ZZ-ZZ-ZZ-ZZ-20100727_LORRIM_lg.jpgOn the Way to Pluto: Messier 784 visiteCaption NASA:"The New Horizons team calibrates the Long Range Reconnaissance Imager (LORRI) by taking pictures of the Open Star Cluster Messier 7 (M 7). This is the first LORRI image of M 7 taken during Annual Checkout (ACO); the 100-millisecond manual exposure was taken on June 25, 2010. A preliminary comparison of this image to a 2008 LORRI picture of M7 indicated no degradation or change in LORRI's performance".MareKromium
