Imagine sitting there, with that view, in real time. Seeing the planet rotate. Its bands swirling. And its moons orbiting.


Oh. Sorry. Gary says you would only see darkness. Never mind.

First in-orbit picture. More to come soon. Can't wait

Fantastic image, but of course always better with the original source: www.nasa.gov...

This color view from NASA's Juno spacecraft is made from some of the first images taken by JunoCam after the spacecraft entered orbit around Jupiter on July 5th (UTC). The view shows that JunoCam survived its first pass through Jupiter's extreme radiation environment, and is ready to collect images of the giant planet as Juno begins its mission.

The image was taken on July 10, 2016 at 5:30 UTC, when the spacecraft was 2.7 million miles (4.3 million kilometers) from Jupiter on the outbound leg of its initial 53.5-day capture orbit. The image shows atmospheric features on Jupiter, including the Great Red Spot, and three of Jupiter's four largest moons.

JunoCam will continue to image Jupiter during Juno's capture orbits. The first high-resolution images of the planet will be taken on August 27 when the Juno spacecraft makes its next close pass to Jupiter.

On the topic of JunoCam's resolution, I just saw it stated at the Unmanned Spaceflight Forum that the best resolution of Jupiter we'll see will be 4 km/pixel! Some really, really great images are ahoy.

Wow..gorgeous image. Thanks for posting. Never seen Jupiter like this before.

Study up on the JUNOCAM. There will be a test in a while.

Search (can't link):
Junocam: Juno’s Outreach Camera

Pray, tell us, what is it about JunoCam that we don't already know, and how does it make "invisible light" visible? The ball is in your court.

Oh wow, just reading up on this mission, the engine is British built

Nice to see we still have some involvement with these deep solar system missions.

No, I never said that. I have no doubt that from close range there will be visible light, the question would be as to the source of the light. Is it reflected sunlight, or is it from light generated by UV, or maybe even cosmic ray bombardment of the atmospheric components? The colour filter centre wavelengths have been chosen to match well known emission lines of certain substances, can you identify them? We know the IR filter is for methane.

GaryN, with all due respect, I don't want you to argue your case in this thread please. You have your own 40+ thread. Cheers mate. Lets keep it on topic.

Now, about this image. I know it's blurry and I know it's nothing special really but is anyone else here having very strong feelings of awe and emotion looking at it? I am profoundly moved by this beautiful, simple image.


PHAGE: yes..image that beautiful view. The approach time lapse "ballet" video was stunning.

WOOGLEUK: Yes, I read that today too. Very cool.

But the rest of them (red, green, and blue) are broadband filters: red (600–800 nm), green (500–600 nm), blue (420–520 nm).

So whatever argument you wanted to make falls flat again.

(P.S. I'm happy to post about this here because it's a Juno and JunoCam topic)

Come on NASA!

2 million Rads?
that can not be from the sun?
and they say in the first vid that they use titanium to shiled from it.
I did not think titanium could shiled from radiation?
gold or lead yes.

Why would Ti not be able to shield?

It might be tomorrow. I'm impatient too.

What might be tomorrow?

Juno is currently performing what is called "capture orbits".

A few days after the JOI Burn, Juno performs a Clean-Up Maneuver to target the time and location of the large Period Reduction Maneuver that is made after the Capture Orbit is complete.

During the long initial Orbit around the Gas Giant, Instruments are turned back on after Jupiter Orbit Insertion. About 50 hours after JOI, all instruments are planned to be powered up and start gathering science data.

As with Jupiter Approach, the duration of the Capture Orbits is utilized to perform more instrument calibration in the Jupiter environment and to obtain initial science data. Teams have sufficient time to learn about instrument and spacecraft behavior during the Capture Orbits so that no additional time is needed when the science phase begins.

As part of this, on July 13th, Juno performed a "cleanup" orbit-trim maneuver (OTM), and the mission control are now looking at how well that went, which will determine whether Juno will require another OTM on July 27th.

God, why cant they just flick everything on and start taking pictures? Jeez...Do they have to be SO meticulous with everything they do?


Joke

No new images or info really but here is an interesting article on the mission

www.inverse.com...

What the hell is Jupiter made of? Lunine and his colleagues are interested in learning exactly what about the composition of the planet because it is likely also “the composition of the building blocks of all the planets of the solar system, including material that may have delivered water to Earth.” “This,” says Lunine, “is kind of the cosmic archeology part.”

Thanks to the Juno twitter feed, i can point you to this link for all the raw images from the approach to Jupter

And one more link to a very interesting article on the Juno Cam

Actually, i just got a chance to finish the article above and i can highly recommend it folks. Lots of info on Jup and Saturn

One guy at the Unmanned Spaceflight Forum created a timelapse of Juno's approach to Jupiter: www.unmannedspaceflight.com...

I've uploaded it to Youtube for easy viewing:

You can just about make out the Galilean moons spinning around it.

One of the images from the approach phase, created by Gerald from the UMSF forum, and colour-balanced by me:



Also, today Juno reached the furthest point in the first of its two "capture orbits" around Jupiter.

Five years after departing Earth, and a month after slipping into orbit around Jupiter, NASA's Juno spacecraft is nearing a turning point. On July 31 at 12:41 p.m. PDT (3:41 p.m. EDT), Juno will reach the farthest point in its orbit of Jupiter for the first time, known as “apojove,” 5 million miles (8.1 million kilometers) from the giant planet. After that point, Jupiter's gravitational grip on Juno will cause the spacecraft to begin falling back toward the planet for another pass, this time with its scientific eyes wide open.

www.missionjuno.swri.edu...

Following the capture orbits, Juno will fire its engine once more to shorten its orbital period to 14 days and begin its science mission.

But before that happens, on Aug. 27, Juno must finish its first lap around Jupiter, with a finish line that represents the mission's closest pass over the gas giant. During the encounter, Juno will skim past Jupiter at a mere 2,600 miles (4,200 kilometers) above the cloud tops.

Not long left now, and in less than a month we'll get some stunning close-up images!
