Hi MeteorWayne. It sure will be. Below. New Horizons LORRI (Long Range Reconnaissance Imager) short exposure image of crescent Io, taken from a distance of 2.5 million / 1.6 million miles on Wednesday 28th February 2007. Smallest details visible are about 12 kilometres / 7.4 miles. This is the penultimate LORRI image from a handful returned to Earth. Some 700 observations are being made of the Jovian system (about double that expected from the Pluto system, quite an oxymoron really). During March & April, all images & observations will be returned by New Horizons. New Horizons has imaged all four of the Galileans (Io, Europa, Ganymede & Callisto) & taken infrared spectra of all four. We have yet to see any images of Callisto at all from New Horizons. Jupiter observations including close up dedicated observations of both the Great Red Spot & Red Spot Junior, night time lightning flashes, polar aurorae, other Jovian nocturnal glows, storm circulations & weather patterns, not to mention the gigantic magnetosphere.. Jupiters rings & how Metis, Adrastea, Amalthea & Thebe model them & the roles they play in their maintainence. Also long range New Horizons LORRI observations of the middle group* moons Himalia (Jupiter's fifth largest at about 184 km / 114 miles across) & Elara (Jupiter's eighth largest at about 78 km / 48 miles across) were to be made, determining rotation rates, orientation & spectra . No surface detail would be visible however as too far away. They orbit Jupiter in a prograde direction (the same as the Galileans & Jupiter's own rotation) but inclined about 27 degrees to Jupiter's equator & are thought to be similar to type S, Silicate asteroids, larger versions of the asteroids 243 Ida, 433 Eros & 951 Gaspra. Perhaps they are captured silicate asteroids. Come end of April, we should have a veritable feast of fresh Jupiter data from New Horizons. <div class="Discussion_UserSignature"> "I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

The PI's Perspective The Tip of the Iceberg March 5, 2007 The intensive phase of Jupiter encounter operations is winding down, but it's not yet over. In the first days of this week, we still have Radio Science Experiment (REX) and Long Range Reconnaissance Imager (LORRI) calibrations using Jupiter system targets, and some imaging to better determine the shapes and photometric phase curves of Jupiter's satellites Elara and Himalia. After that, the encounter becomes almost entirely magnetotail exploration using the Solar Wind at Pluto (SWAP), Pluto Energetic Particle Spectrometer Science Investigation (PEPSSI), and Venetia (Student Dust Counter) instruments; this final phase of the encounter lasts until mid-June. In the past week, we conducted more than 98 separate observing sequences comprising several hundred observations. I am sure that if you're reading this, you've seen some or the entire handful of images we released in the past week — such as the beautiful LORRI imagery of Jupiter's Little Red Spot and Io's Tvashtar volcano. Well, those data represent less than 1/1000th of what we still have to send down, including color imager, more high-resolution LORRI shots, ultraviolet and infrared spectra galore, and, of course, plasma data. So while the "tip of the tip" of the iceberg is now on the ground to whet appetites, we won't have the entire dataset we've taken - all 36 gigabits! - on the ground until at least late April. But don't despair, we will begin downlinking operations this Wednesday, March 7, and will be sending back a few gigabits each week. So you should expect to see nearly weekly data releases coming from New Horizons throughout March and April.

Hi all, Position of New Horizons in relation to Jupiter & the Galileans as of: Friday 9th March 2007 @ 4:30 PM GMT. 22.29 KPS / 13.84 MPS or 80,244 KPH / 49,832 MPH, so has decelerated a little. Distance from Jupiter: 15,838,786 KM / 9,553,331 miles or 0.11 AU, so is pulling away now & is now crossing the orbits of Jupiter's middle group of moons, Leda, Himalia, Lysithea & Elara, all similar to type S, Silicate asteroids.

hi Andrew, thanks again for lending us your informed enthousiasm for the undiscovered realms of the Jovian System. we do not know what surprises Pluto, Charon, Nix & Hydra will have. I have mixed feelings about the fact that 8 years will pass before NH encounters Pluto. Assuming I make it to 2015 alive and well, I will have 'encountered' my 50th birthday - yikes! Of course, since time seems to fly faster and faster as my life goes by, it probably won't seem so long. Time is speeding up due to a gravity boost! <div class="Discussion_UserSignature"> I'm a recovering optimist - things could be better. </div>

portercc · Mar 9, 2007

Thank you Andrew. I got a little irritated last night after viewing raw images from Saturn and Mars and then looking at old Europa images from Galileo...everytime I check on LORRI I'm hoping for a little Christmas...Brellis, this is what happens when you turn fifty...and gravity doesn't always give you a boost. No more whining on my part.

hi portercc I got a little irritated last night after viewing raw images from Saturn and Mars and then looking at old Europa images from Galileo It is frustrating to see how good the detail could be if we still had a Jupiter orbiter in place. Another "New Horizon" on our horizon should be a craft with the staying power of Voyager, and an armada of little sub-craft that can be released at leisure over years or even decades. Then we can wait for tidal events, eruptions, geysers, etc. and drop a probe when things are getting hot! <div class="Discussion_UserSignature"> I'm a recovering optimist - things could be better. </div>

portercc · Mar 10, 2007

Hi Brellis That would be fantastic, an "armada", but it would certainly go against the policy of smaller, cheaper, more frequent. With that many eggs in one basket, I'd be afraid to send it through the asteroid belt. The power requirements would probably set off more than a few protests. Before dedicating everything to the jovian system, I sure would like to get a closer look at Triton. Oh, this is the image that started all the fuss last night. http://photojournal.jpl.nasa.gov/jpeg/PIA01125.jpg

You punk kids....no patience. One of life's little ironies. When you're young and have all the time in the world, you have to have everything right now. Once you get older and learn patience, you might not have enough time left to see what it is you're patiently waiting for. Gonna be a loooong 8 years, MW. In the meantime, we have Cassini and Mars to amuse us, I guess. <div class="Discussion_UserSignature"> "2012.. Year of the Dragon!! Get on the Dragon Wagon!". </div>

That is the plan. Maybe I should yell at them directly more often. Hmmmm.... Where's this week's post-it note??? There's actually a point there. &%$#@!in' about it here doesn't accomplish much.

I bet LORRI has something for us Monday.

The New Horizons Long Range Reconnaissance Imager (LORRI) snapped this photo of Jupiter's ring system on February 24, 2007, from a distance of 7.1 million kilometers (4.4 million miles). This processed image shows a narrow ring, about 1,000 kilometers (600 miles) wide, with a fainter sheet of material inside it. "This is one of the clearest pictures ever taken of Jupiter's faint ring system," says Dr. Mark Showalter, a planetary astronomer from the SETI Institute in Mountain View, Calif., who planned many of the ring images. "The ring looks different from what we expected — it has usually appeared much wider." Showalter suggests that the ring's largest boulders are corralled into a narrow belt by the influence of Jupiter's two innermost moons, Adrastea and Metis. The ring also appears to darken in the middle, a possible hint that a smaller, undiscovered moon is clearing out a gap. "If there is a smaller moon within those rings, we hope to see it in some of the hundreds of additional images that New Horizons will transmit back to Earth over the next several weeks," says Dr. Andy Cheng, LORRI principal investigator from the Johns Hopkins University Applied Physics Laboratory in Laurel, Md. Showalter adds that the faint glow extending in from the ring is likely caused by fine dust that diffuses in toward Jupiter. This is the outer tip of the "halo," a cloud of dust that extends down to Jupiter's cloud tops. The dust will glow much brighter in pictures taken after New Horizons passes to the far side of Jupiter and looks back at the rings, which will then be sunlit from behind. Jupiter's ring system was discovered in 1979, when astronomers spied it in a single image taken by the Voyager 1 spacecraft. Months later, Voyager 2 carried out more extensive imaging of the system. It has since been examined by NASA's Galileo and Cassini spacecraft, as well as by the Hubble Space Telescope and large ground-based observatories.

I think the colours you used are more or less correct. I hope that you do not mind, but I have downloaded them. If I use them on further discussions, you WILL be acknowledged, provided I have your permission!!!. No problem, I don't get out much (Space Science & Astronomy is mostly all I have time for). Here is another image with what appears to be some small bright object rising above the lower right plume. My initial chicken and egg question was - Is there enough force from these huge eruptions to send some of its mass in larger chunks towards other worlds in the Jovian system. The Long Range Reconnaissance Imager (LORRI) on New Horizons captured another dramatic picture of Jupiter's moon Io and its volcanic plumes, 19 hours after the spacecraft's closest approach to Jupiter on Feb. 28, 2007. LORRI took this 75 millisecond exposure at 0035 Universal Time on March 1, 2007, when Io was 2.3 million kilometers (1.4 million miles) from the spacecraft. Io's dayside is deliberately overexposed to bring out faint details in the plumes and on the moon's night side. The continuing eruption of the volcano Tvashtar, at the 1 o'clock position, produces an enormous plume roughly 330 kilometers (200 miles) high, which is illuminated both by sunlight and "Jupiter light." The shadow of Io, cast by the Sun, slices across the plume. The plume is quite asymmetrical and has a complicated wispy texture, for reasons that are still mysterious. At the heart of the eruption incandescent lava, seen here as a brilliant point of light, is reminding scientists of the fire fountains spotted by the Galileo Jupiter orbiter at Tvashtar in 1999. http://pluto.jhuapl.edu/gallery/missionPhotos/pages/031307.html 031307.5 <div class="Discussion_UserSignature"> Ron Bennett </div>

My GOD thats amazing!!! Thank you very much indeed rlb2. Needless to say I have downloaded the above image. Zal Patera was seen by both Voyager 1 & Galileo in some detail, but was always inactive. Wow it has awoken at last!!!! This shows the scientific value of this encounter with the Pluto bound New Horizons!!

do you have a link to a higher res version? I think that would make a great desktop

hi rocketman I believe Andrew got it from New Horizons Sci Op Center. If you download it from there, it's a bit bigger, about 148k. I'll keep poking around. <div class="Discussion_UserSignature"> I'm a recovering optimist - things could be better. </div>
