7,992 pounds (3,625 kilograms) Mission Design and Management. Juno's principal goal is to help scientists understand the origin and evolution of Jupiter.

Juno will improve our understanding of the solar system's beginnings by revealing the origin and evolution of Jupiter. 10 Things You Need to Know About the Juno Mission Get up to speed on the ways this daredevil probe will unlock Jupiter’s secrets, and find out some of Juno’s unique features. Juno is not NASA’s first mission to observe the largest planet in the solar system. Juno’s mission continues.

New discoveries about Jupiter continue to be made.

PJ24 raw images for processing are available now.

Now, 150 days into the mission, Juno should have made six or seven close fly-bys of Jupiter, which means flying through the point of its orbit that is closest to the giant planet. NASA's Juno probe reached Jupiter in July 2016, and scientists' view of the solar system has not been the same since. Its landing probe, Huygens, successfully touched the moon Titan's surface in 2005. This new information suggests the Galileo mission just happened to sample a particularly dry part of Jupiter's atmosphere. From 1995 to 2003, Galileo orbited the planet and probed part way into its atmosphere. Bolton says, “Every 53 days, Juno goes soaring by Jupiter and gets doused by a fire hose of data. During its 24th close flyby of Jupiter, NASA’s Juno spacecraft captured this view of a chaotic, stormy area of the planet’s northern hemisphere known as a folded filamentary region. NASA’s billion dollar mission has been up there for months. PJ24 Images are posted! Like many discoveries, what Juno is making is creating as many questions as answers. Some of our favorite submissions! In the 1970s, Pioneer 10 and Voyagers 1 and 2 sent back observations made as they flew past Jupiter, as did Ulysses in 1992. Juno was launched from Earth in August … Cassini is the first extended mission at Saturn. Atlas V 551 (AV-029) Launch Date and Time. United States of America (USA) Spacecraft Mass. Juno's 20-month Jupiter mission aims to answer questions about the massive planet Bolton also said Juno is likely to discover more moons around Jupiter, which is … Launch - … 6 Minute Read
Juno has also found that Jupiter’s magnetic field us twice as powerful as scientists have hitherto believed. Juno's primary goal is to reveal the story of Jupiter's formation and evolution. Mission Events. There is always something new.” For more discoveries from Jupiter and the other planets of our solar system, stay tuned to science.nasa.gov.
Every 53 days Juno will be sending back more images and scientists will learn more and more about this giant planet. View Featured Images. Using long-proven technologies on a spinning spacecraft placed in an elliptical polar orbit, Juno will observe Jupiter's gravity and magnetic fields, atmospheric dynamics and composition, and evolution.
