Atlas V 551New Horizons
Jupiter
• 484 million miles from Sun (receives ~4% the solar energy)• 9.9 hour day, Jovian year is ~11.9 Earth years• 318 times as massive as Earth• 1,400 more volume, 88,846 miles in diameter• ¼ as Dense (1.33 times water)• 63 moons +• Centuries old Great Red Spot• Largest planetary magnetic field • Radiates more heat than it receives from the Sun• Atmosphere 90% hydrogen, 10% helium; traces of methane,
ammonia, water, ethane, ice• Visited by Pioneers, Voyagers, Cassini, New Horizons• Orbited by Galileo with an atmospheric probe

Trajectory & Science• Five-year cruise to Jupiter, arriving July 2016• Deep Space Maneuver (DSM): 2, 33 min Engine Burns • Earth Fly-by Gravity Assist• Jupiter polar orbit for about one year
– 33 orbits, (11 day period)– Galileo plan was 2 years, lasted 8 years
• Mission ends with de-orbit into Jupiter – Same as Galileo (protect Moons)
• 9 Experiments, 25 Sensors• Color camera - Junocam
– First detailed glimpse of the Jupiter's poles.– 9.3 mile/pixel resolution – Education & Public Outreach
Spacecraft Overview•Spacecraft Mass 7992 pounds, 4 tons
– Larger and more propellant than Galileo with its probe•3 Solar Arrays 8.7 feet x 29.5 feet, total area 650 ft2
– 15 kilowatts at Earth, 450 watts at Jupiter (3-4%)– 50% more efficient then 20 years ago– All previous Jupiter “visits” used Plutonium RTGs
•Spin-stabilized 3 rpm, like Pioneer for pointing and control– Keeps pointed towards Sun
•Propulsion – Bi-propellant system, 4400 lb, 2 tons– 145 lbf thrust main engine with a protective cover
•Titanium “Vault” to protect Electronics from Magnetic field– Weights 157 kg (346 lb)– Shields from electrons and protons– Testing difficult due to vacuum,
