A NASA spacecraft with a Johns Hopkins University Applied Physics Laboratory-built instrument that works to measure high-energy particles is scheduled to reach Jupiter on July 4 as part of a mission to study the planet and the universe.
Johns Hopkins APLâ€™s Jupiter Energetic Particle Detector InstrumentÂ onboard the Lockheed Martin-built Juno spacecraft has three detectors designed to provide a 360-degree view of the space aroundÂ the space vehicle, APL said Wednesday.
The JEDI detectors will work to collect data on high-energy particles that are responsible for the development of auroras around Jupiterâ€™s polar regions as well as measure neutral atoms that the planetâ€™s auroral atmosphere emits.
â€œJupiterâ€™s aurora has a power density 10 times greater than Earthâ€™s, and an overall power that is a factor of 100 greater,â€ said Barry Mauk, lead of the JEDI investigation team at Johns Hopkins APL.
â€œWhat we want to know is, how is this system energized?â€
Other instruments aboard Juno that will be used in magnetic field and particle investigations around the planet include the Southwest Research Institute-made Jovian Auroral Distributions ExperimentÂ tool, Waves instrument and the Magnetometer ExperimentÂ equipment.
Juno is scheduled to enter Jupiterâ€™s orbit five years after it was launched in 2011.
