On 27 August 2016, Jupiter was involved in two interesting events. At around 7:44 am CDT the Juno spacecraft made a very close and fast flyby of the planet going 130,000 mph. It came within 2600 miles of the cloud tops, the closest to the clouds for the entire mission of 35 more orbits. NASA reported the entire suite of scientific instruments was turned on and functioned well. Data will be returned over the next days and weeks.
The image at left is a view of the north pole of Jupiter just prior to the flyby. The polar orbit is a first for Jupiter exploration.
According to Scott Bolton, principal investigator, “We are getting some intriguing early data returns as we speak. It will take days for all the science data collected during the flyby to be downlinked and even more to begin to comprehend what Juno and Jupiter are trying to tell us. We are in an orbit nobody has ever been in before, and these images give us a whole new perspective on this gas-giant world.”
High resolution images will be released in the next two weeks.
More information and details about the Juno mission are available at this previous post.
At sunset also on the 27th, Jupiter and Venus aligned about 1/2˚ apart low in the western sky. That is the width of a full-moon. The dense cloud cover earlier in the day gave way to some partially clear sky for the evening show. The air was laden with much moisture and cloud remnants. The planets were visible. But, hazy conditions made their images not sharp and clear. I couldn’t wait for darkness because the clouds were approaching. Below is a wide view and a fully zoomed view. Venus is the upper and brightest of the two.
