When & Where Can You See Juno’s Photos of Jupiter’s Great Red Spot?

NASA experts celebrate at a press conference after the Juno spacecraft was successfully placed into Jupiter's orbit. With Juno passing Jupiter's Red Spot today, how long will we have to wait to see photos?

NASA’s Juno spacecraft is flying by Jupiter’s Great Red Spot today and coming within 2,200 miles of Jupiter’s surface. This is the first close up we’ve ever seen of the 10,000 mile-wide spot on Jupiter’s surface, believed to be a monumental storm centuries old. Juno will be taking photos of the Great Red Spot as it flies over, but those photos won’t be available immediately. When will they be available and where can you go to see them?

Although Juno is passing over the Great Red Spot at around 6:55 p.m. Pacific (9:55 p.m. Eastern), the photos won’t be available for the public to see right away. NASA is estimating that the pictures will be available by Friday, July 14, and one NASA expert (see below) said it might even be at least a day before that on July 13 or possibly sooner.

Candy Hansen from NASA’s Planetary Science Institute shared more details about this on the Unmanned Spaceflight discussion forum. She said it’s not known exactly when the images will be downlinked, but it will happen as fast as possible because of the huge amount of interest. She said the most conservative estimate for photos was July 14, but they could actually arrive one day before that.

The reason for the delay is that during the flyby, Juno won’t be facing in a direction to communicate with Earth. It may even be a few hours before NASA even gets confirmation that the spacecraft is still functioning right and intact. After that, the data must be downloaded and then the photos are sent in the order in which they were taken.

Scott Bolton, of the Southwest Research Institute in Texas, told ABC Science that the first up-close views might not even arrive until at least this weekend. (The pictures taken from farther away will start arriving first.)

Here’s what Hansen said on the Unmanned Spaceflight discussion forum about the transmission of images from Juno:

When will the GRS images be downlinked? These are the factors:

* We have no downlink during the perijove pass because the spacecraft is in the MWR attitude. This means that all data must be stored on-board. The JunoCam onboard storage is 1181 Mb.
* Once downlink starts we play back engineering first, then FGM, then the other instruments
* The instrument round-robin will start at 6:40 am on Tuesday; JunoCam gets roughly 6 min per hour
* We start by playing back the images collected at -24 hr. Those images are compressed, so it is difficult to calculate the speed of playback precisely. Also, if other instruments’ buffers empty early then playback of JunoCam data will speed up.
* If the GRS images happen to be played back in the middle of the night there is no one at MSSS to see that they’ve arrived – that will happen at open of business
* Once we get the actual images we still need the c kernel with the spacecraft attitude to run the processing pipeline. Usually the C kernel arrives within a day of perijove, so this shouldn’t be a delay.
* As soon as the raw images are posted we will let everyone know that they are available at missionjuno.

Very conservatively I’ve estimated July 14, expecting that it is likely we’ll see them at least a day before.

Of course, the next question is which webpage you should be constantly refreshing to see the photos.

As soon as they arrive, the Great Red Spot’s unprocessed photos will be posted on this linkNASA actually relies on the amateur image-processing community to help process the raw data into the photos you’re likely waiting to see.

The Great Red Spot is larger in diameter than the Earth. It’s been studied since the 1800s, but even in the 1600s there were reports of people seeing a large spot on the surface of Jupiter. No one is completely sure how the storm has managed to stay intact all this time.

Designation of an object as a “planet” has nothing to do with its ability to host life. Additionally, assuming that Jupiter could not host life is unwarranted.

JOHN MAYOR

These “objects” circling suns aren’t “wanderers”!… and so, they’re not “planets”! But!… whatever their MAIN CATEGORY should be, there is a NECESSARY DISTINCTION to be made between HABITABLE “objects” and INHABITABLE “objects”! And the FACT that the designation of these “objects” has nothing to do– today!– with their ability to host life, IS THE PROBLEM I’M ATTEMPTING TO ADDRESS! Additionally, NO ASSUMPTION HAS BEEN MADE BY ME, THAT JUPITER C-O-U-L-D N-O-T HOST LIFE!… OR ANY OTHER GASEOUS GIANT! And, just as it could have been assumed about earth, at an earlier UNSTABLE STAGE in its evolution! Although!… Jupiter may be unable NOW, to host life!… and, as may be the case with all other gaseous giants!
.
Simply put… in attempting to make the BOLD CLAIM that formative gaseous giants can’t host life, necessitates the presentation of PROOFS that such is the case!… and such is the goal of science!… but, whether such will be able to host life once such become STABLE (if at all possible!… see, Kelt-9B!), is another issue altogether! And so, the scientific argument to be made re gaseous giants, is whether the designation of inhabitable is valid for such “objects (i.e., within their specific gaseous state!)”!… and ifn’t, under what conditions/ circumstances/ parameters can these be deemed HABITABLE! And in PROVING that such “objects” within specific parameters are to be classified as INHABITABLE, we then FOREVER DISTINGUISH THESE from those proven HABITABLE! And my case is… my point is!… LET’S MAKE THE ASSERTION! And let the science– and the reclassification!– begin!
.
Please!… no emails!… Jesus is Lord!

P.S.: I believe it’s time to end the designation, “planet”, for gaseous “objects” circling galactic suns! And because, as such “objects” possess no “habitable geography” wherein biological/ chloe can live… let alone, “sentient life”!… it’s a stretch– to say the least!– to place these “objects” in the same category as planets like earth! Therefore, a new classification OTHER than planet, should be entertained! And maybe… and for want of a better description!… a “para-planet” or “proto-planet” may be a more apt description for such “objects”! And so… from hot gaseous “proto-planets”/ “para-planets” such as KELT-9B, down to where such “proto-planets” show evidence of ANY FORM of biological/ chloe life, we state, that within “such and such parameters”, such “proto-planets” will be classified as such, until a “biological/ chloe threshold” is reached, wherewith, such “para-planets” enter the domain of planets (i.e., HABITABLE PLANETS!)! And if for no other reason, that to achieve a clearer understanding of “planetary evolution”!

Planet means “wanderer”, not a place to live. Jesus is Myth!

Hello Mr. Atrophy!:…
.
I believe that most of us are familiar with the classic definition of the use “planet”!… and, that “wandering” isn’t synonymous with a terminologic designation of habitable!… or that of inhabitable! But, that misses my point and argument of our need for a clearer understanding of what these “objects” are, and how best to classify them! Further, the fact that these objects are deemed “wanderers” doesn’t mean that these “disparate objects” should be included within one lone main Taxonomy!
.
To be categorically and descriptively correct, these disparate objects don’t “wander”!… as wandering suggests an “UNCONTROLLED” and haphazard movement through space!… or– worse!– a “willful” haphazard movement through space! And, the latter description/ designation, would be RIDICULOUS!
.
NOTHING within our universe is “UNCONTROLLED” in the sense that PHYSICAL LAWS ARE NOT AT WORK!… and ditto, for the term/ notion of “haphazardness”! EVERY “PLANET” that has been examined, can be “BOUND” to one or more suns– PRIMARILY!– and to other planets and moons! Therefore, such are not “wandering”; but rather, are moving through the agency of “physical constants”/ physical laws! Indeed, the very phrase “wanderer”, is WHOLLY OPPOSITE to what these disparate objects actually do! And, a more categorically and descriptively proper expression for what these disparate objects are and do, respectively, would be, HELIOSFAIREA (from the Greek word Helio(s), for “sun”, and sfairea, for “spheres” or orbs!… and helio(sfaira), in the singular!… or– but, more crudely!– HELIORBS!) and HELIODEOSFAIREA (again, helio(s) for “sun”… deó, for “bound”, and sfairea, for “spheres” or orbs!)! But, whether HELIOSFAIRA or HELIORB… or, otherwise!… the disparate objects within our universe’s galactic solar systems that/ which may be reclassified under a new Nomenclature, must yet be SUBCATEGORIZED, to provide a clearer understanding of the distinctions between them! And one basic distinction to be made between Heliosfaira/ Heliorbs, is habitable versus inhabitable!… and so, a perceived need for the subcategorizes of, anstatheróheliosfaira/ anstatheróheliorb, and statheróheliosfaira/ statheróheliorb, is recognized (the Greek prefix an-, for “un-“, or “not”, and the prefix statherós, for “stable”!)! And, the “gaseous giants”– specifically!– would fall into the anstatheróheliosfaira/ anstatheróheliorb category, and those objects revealing an indication of habitability, would fall into the category of statheróheliosfaira/ statheróheliorb!
.
Nevertheless!… let yet further Taxonomic elaborations proceed!… and let these undo and redo, what we’ve come to understand as our respective galactic solar system evolutions!
