Atlas V Juno Mission Overview
Mission Overview Atlas V Juno Cape Canaveral Air Force Station, FL United Launch Alliance (ULA) is proud to be a part of NASA’s Juno mission. Following launch on an Atlas V 551 and a fi ve-year cruise in space, Juno will improve our understanding of the our solar system’s beginnings by revealing the origin and evolution of its largest planet, Jupiter. Juno is the second of fi ve critical missions ULA is scheduled to launch for NASA in 2011. These missions will address important questions of science — ranging from climate and weather on planet earth to life on other planets and the origins of the solar system. This team is focused on attaining Perfect Product Delivery for the Juno mission, which includes a relentless focus on mission success (the perfect product) and also excellence and continuous improvement in meeting all of the needs of our customers (the perfect delivery). My thanks to the entire ULA team and our mission partners, for their dedication in bringing Juno to launch, and to NASA making possible this extraordinary mission. Mission Overview Go Atlas, Go Centaur, Go Juno! U.S. Airforce Jim Sponnick Vice President, Mission Operations 1 Atlas V AEHF-1 JUNO SPACECRAFT | Overview The Juno spacecraft will provide the most detailed observations to date of Jupiter, the solar system’s largest planet. Additionally, as Jupiter was most likely the fi rst planet to form, Juno’s fi ndings will shed light on the history and evolution of the entire solar system. Following a fi ve-year long cruise to Jupiter, which will include a gravity-assisting Earth fl y-by, Juno will enter into a polar orbit around the planet, completing 33 orbits during its science phase before being commanded to enter Jupiter’s atmosphere for mission completion. -

Magnetic torquing is also used to maintain the satellite spin rate at 1/ 12 revolution per minute.

The in-orbit performance has been essentially flawless.

The irregular satellites of the giant planets are believed to have been captured during the evolution of the solar system. Knowing their physical parameters, such as size, density, and albedo is important for constraining where they came from and how they were captured. -
Juno Spacecraft Description
Juno Spacecraft Description By Bill Kurth 2012-06-01 Juno Spacecraft (ID=JNO) Description The majority of the text in this file was extracted from the Juno Mission Plan Document, S. Stephens, 29 March 2012. [JPL D-35556] Overview For most Juno experiments, data were collected by instruments on the spacecraft then relayed via the orbiter telemetry system to stations of the NASA Deep Space Network (DSN). Radio Science required the DSN for its data acquisition on the ground. The following sections provide an overview, first of the orbiter, then the science instruments, and finally the DSN ground system. Juno launched on 5 August 2011. The spacecraft uses a deltaV-EGA trajectory consisting of a two-part deep space maneuver on 30 August and 14 September 2012 followed by an Earth gravity assist on 9 October 2013 at an altitude of 559 km. Jupiter arrival is on 5 July 2016 using two 53.5-day capture orbits prior to commencing operations for a 1.3-(Earth) year-long prime mission comprising 32 high inclination, high eccentricity orbits of Jupiter. The orbit is polar (90 degree inclination) with a periapsis altitude of 4200-8000 km and a semi-major axis of 23.4 RJ (Jovian radius) giving an orbital period of 13.965 days. The primary science is acquired for approximately 6 hours centered on each periapsis although fields and particles data are acquired at low rates for the remaining apoapsis portion of each orbit. Juno is a spin-stabilized spacecraft equipped for 8 diverse science investigations plus a camera included for education and public outreach. -
