NASA’s Juno Spacecraft to Fly Over Jupiter’s Great Red Spot July 10

Just days after celebrating its first anniversary in Jupiter orbit, NASA’s Juno spacecraft will fly directly over Jupiter’s Great Red Spot, the gas giant’s iconic, 10,000-mile-wide (16,000-kilometer-wide) storm. This will be humanity’s first up-close and personal view of the gigantic feature — a storm monitored since 1830 and possibly existing for more than 350 years.

“Jupiter’s mysterious Great Red Spot is probably the best-known feature of Jupiter,” said Scott Bolton, principal investigator of Juno from the Southwest Research Institute in San Antonio. “This monumental storm has raged on the solar system’s biggest planet for centuries. Now, Juno and her cloud-penetrating science instruments will dive in to see how deep the roots of this storm go, and help us understand how this giant storm works and what makes it so special.”
「ジュピターの神秘的な大赤斑はおそらく木星の最もよく知られた特徴です」とサンアントニオのサウスウエスト研究所のジュノーの主任研究員スコット・ボルトン氏は語りました。 「この壮大な嵐は、太陽系最大の惑星である木星で、数百年にわたり激しさを増しています。今回ジュノーに搭載している大気を調査観測する測定器は、この嵐がどれほど深いところから発生しているかを明らかにし、この特別な巨大な嵐の発生や仕組みを解析する助けとなります。

The data collection of the Great Red Spot is part of Juno’s sixth science flyby over Jupiter’s mysterious cloud tops. Perijove (the point at which an orbit comes closest to Jupiter’s center) will be on Monday, July 10, at 6:55 p.m. PDT (9:55 p.m. EDT). At the time of perijove, Juno will be about 2,200 miles (3,500 kilometers) above the planet’s cloud tops. Eleven minutes and 33 seconds later, Juno will have covered another 24,713 miles (39,771 kilometers) and will be directly above the coiling crimson cloud tops of Jupiter’s Great Red Spot. The spacecraft will pass about 5,600 miles (9,000 kilometers) above the Giant Red Spot clouds. All eight of the spacecraft’s instruments as well as its imager, JunoCam, will be on during the flyby.
大赤斑のデータ収集は、木星を覆う神秘的な大気の頂を6回目となる周回の際に実施されます。木星の中心に最も近い軌道には、PDTで7月10日(月)午後6時55分(EDTで午後9時55分)に到達します。その際ジュノーは木星大気の頂から約2,200マイル(3,500km)の高度にあります。 11分33秒後、ジュノーは木星の大赤斑の真上に位置します。その後24,713マイル(39,771キロメートル)をカバーしながら、大赤斑の上空約5,600マイル(9000キロメートル)を通過します。ジュノーの8基の観測機器とカメラであるジュノーカムは、その間稼働して観測を実施します。

On July 4 at 7:30 p.m. PDT (10:30 p.m. EDT), Juno will have logged exactly one year in Jupiter orbit. At the time, the spacecraft will have chalked up about 71 million miles (114.5 million kilometers) in orbit around the giant planet.

“The success of science collection at Jupiter is a testament to the dedication, creativity and technical abilities of the NASA-Juno team,” said Rick Nybakken, project manager for Juno from NASA’s Jet Propulsion Laboratory in Pasadena, California. “Each new orbit brings us closer to the heart of Jupiter’s radiation belt, but so far the spacecraft has weathered the storm of electrons surrounding Jupiter better than we could have ever imagined.”

Juno launched on Aug. 5, 2011, from Cape Canaveral, Florida. During its mission of exploration, Juno soars low over the planet’s cloud tops — as close as about 2,100 miles (3,400 kilometers). During these flybys, Juno is probing beneath the obscuring cloud cover of Jupiter and studying its auroras to learn more about the planet’s origins, structure, atmosphere and magnetosphere.

Early science results from NASA’s Juno mission portray the largest planet in our solar system as a turbulent world, with an intriguingly complex interior structure, energetic polar aurora, and huge polar cyclones.

JPL manages the Juno mission for the principal investigator, Scott Bolton, of Southwest Research Institute. The Juno mission is part of the New Frontiers Program managed by NASA’s Marshall Space Flight Center in Huntsville, Alabama, for the Science Mission Directorate. Lockheed Martin Space Systems, Denver, built the spacecraft. JPL is a division of Caltech in Pasadena. More information on the Juno mission is available at:
