NASA's Juno spacecraft, which left Earth Aug. 5 to began its five-year, 1.7 billion-mile journey to Jupiter, will offer the public the opportunity to participate in the mission's science endeavours, said a researcher from the Planetary Science Institute. The mission will also provide researchers with spectacular close-up colour images of Jupiter, including the first detailed glimpses of the planet's poles, said Candice Hansen-Koharcheck, a senior research scientist at the Planetary Science Institute and co-investigator on the Juno mission. She is also science lead for the spacecraft's camera, called the JunoCam. Read more
A Johns Hopkins Applied Physics Laboratory (APL) instrument that will delve into the dynamics of the solar system's largest planetary magnetic field was launched today aboard NASA's Juno spacecraft. The Jupiter Energetic-particle Detector Instrument (JEDI) will measure energetic particles that flow through and are trapped within Jupiter's space environment, called a "magnetosphere," and study how those particles interact with Jupiter's swirling atmosphere. That interaction generates Jupiter's bright northern and southern lights, called aurora, the most powerful in the solar system. JEDI findings will contribute to Juno's overall mission to find out more about the gas giant's origins, structure, atmosphere and magnetosphere. Read more
NASA's solar-powered Juno spacecraft lifted off from Cape Canaveral Air Force Station in Florida at 9:25 a.m. PDT (12:25 p.m. EDT) Friday to begin a five-year journey to Jupiter. Juno's detailed study of the largest planet in our solar system will help reveal Jupiter's origin and evolution. As the archetype of giant gas planets, Jupiter can help scientists understand the origin of our solar system and learn more about planetary systems around other stars. Read more
