NEW HORIZONS Final Update (For Now)... As of right now, the Pluto-bound New Horizons spacecraft is flying past Mars’ orbit...being at a current distance of 65 million miles from Earth and speeding its way towards an encounter with Jupiter on February 28 of next year. All but one of Horizons’ seven instruments have now been checked out and will begin making observations within a few months [two instruments, the Student Dust Counter (built by the University of Colorado) and the Solar Wind At Pluto (SWAP) device, have already made "first light" observations]. The final instrument to be checked out, the LORRI (LOng Range Reconnaissance Imager) camera, will not open its lens cover and be tested till later this Fall...since the instrument is extremely sensitive to light, and mission engineers don’t wanna risk damaging it if the camera was accidentally pointed at the Sun. In terms of the Jupiter flyby in 2007, the planned observation list for the giant planet will be finalized by October, 2006. New Horizons has already made three trajectory correction maneuvers (TCMs) to fine-tune its flight path to Jupiter and Pluto...two thruster burns on January 28 and 30, respectively, and the third one on March 9.
In terms of mementos that New Horizons is carrying onboard during its journey out of the solar system, it bears a canister holding the ashes of Pluto discoverer Clyde Tombaugh (shown above), a piece of material from the experimental SpaceShipOne vehicle and a Florida coin commemmorating the U.S. space program (both shown below).
Unless events warrant it, I probably won’t talk about New Horizons again till the few months leading up to the Jupiter flyby. See ya!
