Juno Marches On

NASA's Juno spacecraft has completed its thermal vacuum chamber testing. The two-week-long test, which concluded on March 13, 2011, is the longest the spacecraft will undergo prior to launch.

NASA's Jupiter-Bound Spacecraft Taking Shape In Denver
NASA's Juno spacecraft is currently undergoing environmental testing at Lockheed Martin Space Systems near Denver. The solar-powered Juno spacecraft will orbit Jupiter's poles 33 times to find out more about the gas giant's origins, structure, atmosphere and magnetosphere. The launch window for Juno from the Cape Canaveral Air Force Station in Florida opens Aug. 5, 2011.

NASA Goddard Delivers Magnetometers for Juno Mission
The magnetometers developed at NASA's Goddard Space Flight Center in Greenbelt, Md., for the Juno mission to Jupiter were delivered recently to Lockheed Martin in Denver, Colo. Designed and built by an in-house team of Goddard scientists, engineers and technicians, this instrument will map the planet's magnetic field with great accuracy and observe its variations over time. Each of the two vector magnetometers carries with it a pair of non-magnetic star cameras to determine its orientation in space with commensurate accuracy.

Lockheed Martin employees are in the midst of assembling the Juno spacecraft in south Jefferson County, equipping it with "armour" to withstand the radiation rigors of Jupiter.
Juno is scheduled to be launched by Centennial- based United Launch Alliance in August 2011. It will begin a year-long mission of exploring Jupiter's origin and evolution in 2016.

Juno Armoured Up to Go to Jupiter

NASA's Juno spacecraft will be forging ahead into a treacherous environment at Jupiter with more radiation than any other place NASA has ever sent a spacecraft, except the sun. In a specially filtered cleanroom in Denver, where Juno is being assembled, engineers recently added a unique protective shield around its sensitive electronics. New pictures of the assembly were released today.

NASA is officially moving forward on a mission to conduct an unprecedented, in-depth study of Jupiter.
Called Juno, the mission will be the first in which a spacecraft is placed in a highly elliptical polar orbit around the giant planet to understand its formation, evolution and structure. Underneath its dense cloud cover, Jupiter safeguards secrets to the fundamental processes and conditions that governed our early solar system.

"Jupiter is the archetype of giant planets in our solar system and formed very early, capturing most of the material left after the sun formed. Unlike Earth, Jupiter's giant mass allowed it to hold onto its original composition, providing us with a way of tracing our solar system's history" - Scott Bolton, Juno principal investigator from the Southwest Research Institute in San Antonio.

NASA Selects New Frontiers Mission Concept Study

NASA today announced a mission to fly to Jupiter will proceed to a preliminary design phase. The mission is called Juno, and it is the second in NASA's New Frontiers Program.

The mission will conduct a first-time, in-depth study of the giant planet. This mission proposes to place a spacecraft in a polar orbit around Jupiter to investigate the existence of an ice-rock core; determine the amount of global water and ammonia present in the atmosphere; study convection and deep wind profiles in the atmosphere; investigate the origin of the Jovian magnetic field; and explore the polar magnetosphere.

"We are excited at the prospect of the new scientific understanding and discoveries by Juno in our continued exploration of the outer reaches of our solar system during the next decade," said Dr. Ghassem Asrar, deputy associate administrator for NASA's Science Mission Directorate.

At the end of the preliminary design study, the mission must pass a confirmation review that will address significant schedule, technical and cost risks before being confirmed for the development phase.

Dr. Scott Bolton of Southwest Research Institute, Boulder, US, is the Principal Investigator. NASA's Jet Propulsion Laboratory, Pasadena, US, will provide mission project management. Lockheed Martin Space Systems in Denver will build the spacecraft.

NASA selected two proposed mission concepts for study in July 2004 from seven submitted in February 2004 in response to an agency Announcement of Opportunity. "This was a very tough decision given the exciting and innovative nature of the two missions," Asrar added.

The selected New Frontiers science mission must be ready for launch no later than June 30, 2010, within a mission cost cap of $700 million.

The New Frontiers Program is designed to provide opportunities to conduct several of the medium-class missions identified as top priority objectives in the Decadal Solar System Exploration Survey, conducted by the Space Studies Board of the National Research Council.

The first NASA New Frontiers mission will fly by the Pluto-Charon system in 2014 and then target another Kuiper asteroid belt object.
