It will arrive on Monday. Hubble also took some stunning images of Jupiter's auroras.

Juno To Arrive at Jupiter Tonight

NASA’s solar-powered Juno spacecraft is set to arrive at Jupiter after an almost five-year journey. Juno will perform a suspenseful orbit insertion maneuver, a 35-minute burn of its main engine, to slow the spacecraft so it can be captured into the gas giant’s orbit. NASA TV coverage of orbital insertion begins on July 4 at 10:30 p.m. EDT.

Once in orbit, the spacecraft will circle the Jovian world 37 times during 20 months, skimming to within 3,100 miles (5,000 km) above the cloud tops. This is the first time a spacecraft will orbit the poles of Jupiter, providing new answers to ongoing mysteries about the planet’s core, composition and magnetic fields.

Seems there are two threads on Jupiter. Think you were first Bob. :)

Juno has been captured!

Let the science begin!

Exciting!!

We’ve visited Jupiter before with probes, but Juno is special. This spacecraft is designed to fly closer than any man-made object has ever gotten to Jupiter, probing beneath its roiling cloud cover to unlock new secrets. And Jupiter is a fascinating world. It could even help explain Earth’s origins (read more about that here).

That's cool. I didn't know a microphone was on board.

Obviously since there is nothing to create air preasure waves a different transducer had to be used.

NASA’s Juno Spacecraft Sends First In-orbit View





The JunoCam camera aboard NASA's Juno mission is operational and sending down data after the spacecraft’s July 4 arrival at Jupiter. Juno’s visible-light camera was turned on six days after Juno fired its main engine and placed itself into orbit around the largest planetary inhabitant of our solar system. The first high-resolution images of the gas giant Jupiter are still a few weeks away.

"This scene from JunoCam indicates it survived its first pass through Jupiter's extreme radiation environment without any degradation and is ready to take on Jupiter," said Scott Bolton, principal investigator from the Southwest Research Institute in San Antonio. "We can't wait to see the first view of Jupiter's poles."

Your welcome, Annie. Sorry so late in my reply.

Juno is ready for science now.

Juno heads back toward Jupiter, ready for science

After braking into a highly elliptical path around Jupiter on July 4, NASA's Juno spacecraft finally reached the high-point of its initial 53.4-day orbit Sunday, setting up a long plunge back toward its quarry and an Aug. 27 close encounter with all of its instruments up and running.

"We're very pleased about the state of the spacecraft and the state of the instruments, they all look really good," Rick Nybakken, Juno project manager at the Jet Propulsion Laboratory, said in an interview.

No, it may take a week. Download from Jupiter is not fast, due to power limits.

Jupiter’s North Pole Unlike Anything Encountered in Solar System


NASA’s Juno spacecraft has sent back the first-ever images of Jupiter’s north pole, taken during the spacecraft’s first flyby of the planet with its instruments switched on. The images show storm systems and weather activity unlike anything previously seen on any of our solar system’s gas-giant planets.

Juno successfully executed the first of 36 orbital flybys on Aug. 27 when the spacecraft came about 2,500 miles (4,200 kilometers) above Jupiter’s swirling clouds. The download of six megabytes of data collected during the six-hour transit, from above Jupiter’s north pole to below its south pole, took one-and-a-half days. While analysis of this first data collection is ongoing, some unique discoveries have already made themselves visible.



This image from NASA's Juno spacecraft provides a never-before-seen perspective on Jupiter's south pole.

The JunoCam instrument acquired the view on August 27, 2016, when the spacecraft was about 58,700 miles (94,500 kilometers) above the polar region. At this point, the spacecraft was about an hour past its closest approach, and fine detail in the south polar region is clearly resolved.

Some very expensive pictures. Looks to me like what we always see on Jupiter from our telescopes; high winds, rotations and persistent storms.

What is (are) the gas(es) that Jupiter is made of and does it have a solid core and are there mountains ?
Can we map it's surface if there is one?

Why only a limited number of orbits--I presume we are going in to the atmosphere to try to learn the answers to some of there questions. Apparently radar imaging won't work.

Why isn't there enough power to send pictures or even video in real time?

Jupiter is far away from the SUN and solar panels are power limited.

Yes I would suspect so. Why not a small nuclear power source of some type.
