{ New Horizons Emily Linden Bear Elder

 Leaving Earth faster than any other spacecraft to date  First spacecraft to be launched directly into a solar escape trajectory  Launched on January 19, It flew by Jupiter on February 28, 2007 at 5:43:40 (to the exact time) Background

 Uses a plutonium-powered radioisotope thermoelectric generator  Rex  SDC  LORRI (Long Range Reconnaissance Imager)  478 kilograms (1,054 pounds) at launch  0.7 m (27 inches) tall, 2.1 m (83 inches) long and 2.7 m (108 inches) at its widest. Details of Spacecraft

Results Pluto is depicted by the white arrow. The distance is 4.2 billion kilometers (2.6 billion miles) from the spacecraft. Huge cyclonic storms, the Great Red Spot and the Little Red Spot, and wispy cloud patterns.

Results To the left is Io, the volcanic moon; and on Jupiter is the shadow of Ganymede as it passes over Jupiter. New Horizon took a picture of Io when its volcanoe Tvashtar erupted.

{ Cassini Bear Elder Emily Linden

Spacecraft Details  The orbiter is about the same size as a 30 passenger school bus. It weighs roughly 5,650 kg (6 tons)  Cassini's instrumentation consists of: a radar mapper, a CCD imaging system, a visible/infrared mapping spectrometer, a composite infrared spectrometer, a cosmic dust analyzer, a radio and plasma wave experiment, a plasma spectrometer, an ultraviolet imaging spectrograph, a magnetometer, an ion/neutral mass spectrometer

Objectives  Cassini’s objectives were flyby of Jupiter, examine the great red spot more extensively, and some missions regarding Saturn.

Results  Scientists used the Cassini spacecraft to reveal Jupiter's magnetosphere, a vast, invisible whirling bubble of charged particles surrounding the planet. The data revealed how Jupiter interacts with particles from our Sun. The results helped scientists understand Earth's own magnetosphere, which shields us from harmful solar radiation.  Cassini also revealed Jupiter's radiation belts to be much harsher than expected -- information that will help engineers protect future robotic spacecraft -- and spotted new details in Jupiter's auroras.
