Juno spacecraft to attempt polar Jupiter Orbit Insertion 7/4

i want moar.....

In your case it would not normally be sarcasm.

It would just be one of your typical serious posts.

Actually NASA didn't go full-bore $$ on Juno's camera because it is only expected to last 7 orbits or so before the radiation destroys the sensor. What they are really after is the data from the high-powered radar that can "see" 350 miles through Jupiter's atmosphere. All the other components are inside a titanium-shielded box, since Jupiter's magnetic field is so dense and large it traps much more cosmic radiation than the Van Allen belts do. This probe will take a beating doing it's job and they came up with the elliptical orbit scheme to help it last. It uses it's radar. camera, other instruments when it's close to the planet then it gets outta there pretty fast and by the time it loops around for another pass a different "slice" of the planet will be underneath it so eventually it should be able to radar-map the entire surface. Let's hope it works, it was not cheap..

Actually I wonder why they arn't keeping the craft around longer, it seems like such a waste to deorbit it so fast. Or do they know the radiation is going to destroy it anyway? Could be neat to just leave it in orbit with Jupiter permanently. Would need to make the orbit much larger though.

When the mapping is complete it will be sent into the atmosphere to burn up, NASA does not want it to take an accidental turn and crash into one of Jupiter's many moons. By using a long. elliptical, orbit it minimizes the amount of exposure to the searing radiation.

Bummer, Juno won't get any closer due to engine troubles

http://www.universetoday.com/133501/juno-will-get-no-closer-jupiter-due-engine-troubles/

"On July 4th, 2016, the Juno mission established orbit around Jupiter, becoming the second spacecraft in history to do so (after the Galileo probe). Since then, the probe has been in a regular 53.4-day orbit (known as perijove), moving between the poles to avoid the worst of its radiation belts. Originally, Juno’s mission scientists had been hoping to reduce its orbit to a 14-day cycle so the probe could make more passes to gather more data.

To do this, Juno was scheduled for an engine burn on Oct. 19th, 2016, during its second perijovian maneuver. Unfortunately, a technical error prevented this from happening. Ever since, the mission team has been pouring over mission data to determine what went wrong and if they could conduct an engine burn at a later date. However, the mission team has now concluded that this won’t be possible."

Actually, Juno will last a lot longer now, so theres a lot of information and experiments that couldnt previously be gathered that can now be gathered.

but it is still hanging around.

Sucks, but at least they did not lose complete contact with it, so it could be worse. They can still gather data and what not.

Wonder if it's close enough that it will start to lithobrake and slowly lower the apogee making each orbit shorter. Of course it will eventually get sucked in if that's the case too, but think that was their plan.

Some new pictures from Juno.

"The JunoCam is not exactly part of the science payload. It was included in the missions to help engage the public with the mission, and it appears to be doing that job well. The Junocam’s targets have been partly chosen by the public, and NASA has invited anyone who cares to to download and process raw Junocam images. You can see those results throughout this article."

Check out this site for more images and where and how to DL raw images to play with. https://www.missionjuno.swri.edu/junocam/processing

This image of Jupiter from the Juno probe shows an intricate dance of storms and swirls. The enhanced color image was captured on February 2nd, from only 14,500 km above the gas giant's cloud tops. Image: NASA/JPL-Caltech/SwRI/MSSS/Roman Tkachenko

Latest pictures and video from Juno of Jupiter. Like the soundtrack.

Good stuff. So the red spot in July.

That flyby lapse is pretty cool.

Nice! I wonder if those are actual optical images or just heavily colorized radio/xray etc though. If those are actual real optical images, then that's even more impressive. Either way it's incredible to get such high res imagery from the planet. The amount of science data they're getting is probably crazy too.

The music is fitting.

It's actually crazy to think that what was complete science fiction in the 2001 movie is somewhat happening. Like, we didn't send people there, but we technically could have. It's just that there's no reason to and it's not really feasible and not because we don't have the tech.

Last night Juno made its closest pass to the red spot some 5600 miles above it. All its instruments were pointing at it. We should be getting some images back soon. They have discoverd a lot about the makeup of jupiter if you are intrersterd you can read about it here https://www.space.com/36999-jupiter-mysteries-cyclones-auroras-juno-probe.html

Bad ass. Between this and New Horizons, NASA has really been killing it lately.

Stumbled upon this site. Lots of Juno stuff new pics and you can DL and tweak and resubmit.
