Below a nice LORRI mug shot of my fave Volcanic Io, which I have enlarged & enhanced. Hi portercc. Yes I think that we will be getting some pretty good Jupiter images soon. I am looking forward to further images of ALL of the gallileans as well as the hi res Great Red Spot images. Your link to the Titan island in the hydrocarbon lake image is fantastic. I have downloaded it. Thank you both to viper101 & MeteorWayne for putting the link & original images on this thread. I have made some good friends here on SDC. Distance: 4.1 million kilometres / 2.5 million miles. Monday 26th February 2007. My name is sailing past Jupiter. Certificate number 33663. Quite a thrill really. Thanks for ALL of your updates. Please keep them coming. Andrew Brown. <div class="Discussion_UserSignature"> "I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

New article. NASA Probe Spies Jupiter's Moons and Storms in Flyby By Tariq Malik Staff Writer posted: 28 February 2007 7:16 a.m. ET Visions of a volcanic plume spewing out of Jupiter’s moon Io and a swirling storm are among the first images returned by a NASA probe as it approached an early-morning swing past the gas giant today. NASA’s New Horizons spacecraft sent home the new look at Jupiter’s “Little Red Spot” and the planet’s volcanic moon Io as it closed in on the gas giant during a planetary flyby that was due to reach its closest approach at about 12:45 a.m. EST (0545 GMT) today. "This is the best image of a large volcanic plume on Io since the Voyager flybys in 1979," John Spencer, deputy leader of the New Horizons Jupiter Encounter Science Team at Colorado’s Southwest Research Institute (SwRI), said in a written statement released Tuesday. The flyby is a major milestone for New Horizons’ flight and allows mission scientists to collect new Jupiter observations in a dress rehearsal for the probe’s planned Pluto encounter in 2015 At its closest pass, New Horizons was expected to swing within 1.7 million miles (2.3 million kilometers) of Jupiter before shooting onward on a course through the gas giant’s long magnetotail -- the non-Sunward side of the Jovian magnetic field. It is during that time that astronomers hope to uncover new secrets of the interactions between Jupiter’s magnetosphere, the Sun’s solar wind and the gas giant’s aurora displays. “This is really the payback time,” SwRI’s David McComas, principal investigator for New Horizon’s Solar Wind Around at Pluto (SWAP) instrument, told SPACE.com before today’s planned flyby. “The big show, it probably isn’t just one day or two…we’ll be inside the magnetosphere of Jupiter for many weeks.” Launched in January 2006, New Horizons is expected to grab a 9,000-mile per hour (14,484 kph) speed boost from its p <div class="Discussion_UserSignature"> "I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

Just thought I'd throw this up here. Slept through my watch alarm (not very loud) so this is the graph from about 1:35 after closest approach. I notice heliocentric speed has continued to increase past closest encounter, have to look at the geometry. <div class="Discussion_UserSignature"> But the Krell forgot one thing John. Monsters.

Fine illustrations. The BBC had this to write about the New Horizons mission. only 1 year out and at Jove already. That is VERY fast, considering it took Cassini several years to get to Saturn, about twice as far out as Jove. But it would need to be very fast-- Jove ~800 million kms. from sun Saturn ~1.4 billion " " " Pluto 4.4--7.4 BILLION kms. out. What is its velocity now? Must be very high.

Position of New Horizons relative to Jupiter & the Galileans as of: Wednesday 28th February 2007 @ 5:00 PM GMT. New Horizons is now clearly past Perijove & is still accelerating. Shortly New Horizons will be imaging the lightning in the thunderstorms & aurora in the night hemisphere of Jupiter. Hi chesh. Heliocentric speed: 23.21 KPS = 14.41 MPS or 83,556 KPH / 51,888 MPH & is still accelerating. Remember, Cassini / Huygens took a very circular route to Saturn, twice past Venus, once past Earth & Jupiter. Cassini / Huygens had to only go as far as the orbit of Saturn & also had to enter orbit aroung the giant ringed planet & drop Huygens onto Titan, so the approach speed to Saturn had to be moderate. New Horizons on the other hand, is on a solar escape trajectory into intersteller space via Jupiter, Pluto & the Kuiper Belt.

chesh · Feb 28, 2007

G'day, 3488! Good Lord!! 23.21 kps is very fast, but once it is past Jove the velocity will no longer accelerate. Maximum velocity kick from a planetary encounter is over pretty much after it has left "perijovian" point. After that, Jove's gravity will act a bit to slow it down. So a slight deceleration is actually ongoing. Still, 83,556 kph is very fast. Astonishing!! Has any other mission reached such enormous velocities?

WOOHOO! Pluto, here we come!

Hi chesh. If you see this link with the fascinating post provided by mrmorris the answer is there. New Horizons is NOT the fastest over all, but the fastest to leave Earth. Helios 2 is the fastest ever, due to its small Heliocentric orbit.

Thanks CalliArcale. The detail is just incredible. Like those tremendous thunderstorms to the west. Makes anything the Earth produces, look like amateur efforts. Indeed Pluto here we come!! I do hope that New Horizons did not miss the Pluto Keyhole!!! Andrew Brown. <div class="Discussion_UserSignature"> "I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

at 1900 Z, heliocentric velicity is 23.25 km/sec, 89700 km/hr. That's 14.45 miles per second, or just over 52000 mph. <div class="Discussion_UserSignature"> But the Krell forgot one thing John.

And what's everyone going to being doing during this 8 years? Just hope your all still on this forum in 8 years time to share in the excitement. Not sure if this little bit of information has previously been shared but here it comes again. Some have been wandering about the dearth of images. At the bottom of this page, Ganymede and the New Horizons "Most of the data being gathered by the spacecraft are stored on board and will be downlinked to Earth during March and April 2007." So the best is still to come!

jmilsom · Feb 28, 2007

Well I'm through the first hurdle with my PhD and I am taking some time to catch up on the thread and the NEWS on the mission web site. It seems the flyby has been flawless and there should be a flood of excellent data in the coming weeks. I must say the latest image of the Little Red Spot is spectacular. Perhaps someone can scale it down and post it here. It is beautiful. Great posts everyone, I've enjoyed reading them.

Will New Horizons be imaging Pluto again in the near future, or on the way? I'm curious how it looks now compared to this image for example: http://en.wikipedia.org/wiki/Image:112806_pluto_animation.gif <div class="Discussion_UserSignature"> ----- http://mithridates.blogspot.com </div>

portercc · Mar 1, 2007

Any projections as to the surface temperature of Europa after the Sun balloons out to the orbit of Mars? Will these frozen jewels we are looking at through the eyes of New Horizons become wet? I understand it will be cooler as it reddens but will distance outweigh temperature? I apologize if this belongs in another thread.

Headlines February 28, 2007 Pluto-Bound New Horizons Spacecraft Gets a Boost from Jupiter NASA’s New Horizons spacecraft successfully completed a flyby of Jupiter early this morning, using the massive planet’s gravity to pick up speed on its 3-billion mile voyage to Pluto and the unexplored Kuiper Belt region beyond. “We’re on our way to Pluto,” says New Horizons Mission Operations Manager Alice Bowman, of the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md. “The swingby was a success; the spacecraft is on course and performed just as we expected.” New Horizons came within 1.4 million miles (2.3 million kilometers) of Jupiter at 12:43 a.m. EST, threading an “aim point” that puts it on target to reach the Pluto system in July 2015. During closest approach the spacecraft was out of touch with Earth – busily gathering science data on the giant planet, its moons and atmosphere – but by 11:55 a.m. EST mission operators at APL had established contact with New Horizons through NASA’s Deep Space Network and confirmed its health and status. The fastest spacecraft ever launched, New Horizons is gaining nearly 9,000 miles per hour (14,000 kilometers per hour) from Jupiter’s gravity – half the speed of a space shuttle in orbit – accelerating past 52,000 mph (83,600 km/h) away from the Sun. New Horizons has covered approximately 500 million miles (800 million kilometers) since launch in January 2006, and reached Jupiter quicker than the seven previous spacecraft to visit the solar system’s largest planet. Today it raced through an aim point just 500 miles (800 kilometers) across – the equivalent of a skeet shooter in Washington hitting a target in Baltimore on the first try.

Hi jmilsom. I have cropped it, enlarged & enhanced the Red Spot Junior from New Horizons. Like the thunderstorms to the west!! Possibly with football sized hailstones, torrential rain, snow & updrafts in excess of 360 KPH / 200 MPH. Not to mention the lightning!!!!!

This image of Jupiter's icy moon Europa, the first Europa image returned by New Horizons, was taken with the spacecraft's Long Range Reconnaissance Imager (LORRI) camera at 07:19 Universal Time on February 27, from a range of 3.1 million kilometers (1.9 million miles). The longitude of the disk center is 307 degrees West and the image scale is 15 kilometers (9 miles) per pixel. This is one of a series of images designed to look for landforms near Europa's terminator - the line dividing day and night - where low Sun angles highlight subtle topographic features. Europa's fractured icy surface is thought to overlie an ocean about 100 kilometers (60 miles) below the surface, and the New Horizons team will be analyzing these images for clues about the nature of the icy crust and the forces that have deformed it. Europa is about the size of Earth's moon, with a diameter of 3,130 kilometers (1.945 miles). This is one of a handful of images of the Jupiter system already returned by New Horizons during its close approach to Jupiter. Most of the data being gathered by the spacecraft are stored onboard and will be downlinked to Earth during March and April 2007.

This is New Horizons' best image of Ganymede, Jupiter's largest moon, taken with the spacecraft's Long Range Reconnaissance Imager (LORRI) camera at 10:01 Universal Time on February 27 from a range of 3.5 million kilometers (2.2 million miles). The longitude of the disk center is 38 degrees West and the image scale is 17 kilometers (11 miles) per pixel. Dark patches of ancient terrain are broken up by swaths of brighter, younger material, and the entire icy surface is peppered by more recent impact craters that have splashed fresh, bright ice across the surface. With a diameter of 5,268 kilometers (3,273 miles), Ganymede is the largest satellite in the solar system.

It is quite an oxymoron that Ganymede is the largest & most massive solid object to be imaged in detail by New Horizons. The second largest known KBO Pluto, the primary target is only about half of the diameter & only about one twentyfifth / 4% (Charon, Nix & Hydra included) of the mass of Ganymede at most.

Hi all I have cropped, enlarged & enhanced the giant 240 kilometre / 150 mile high plume from the high latitude volcano Tvashtar, on the Jupiter moon Io. It shows the ballistic 'umbrella' shape rather well. Thank you to MeteorWayne for posting the original image. Thank you kane007. I agree, the best is still yet to come. There is no doubt what so ever about that fact being true. Thanks shuttle-guy. It will be interesting to see the rate of deceleration. It should be less now, seeing as New Horizons is further from the Sun & that New Horizons passed 'behind' Jupiter over the afternoon hemisphere. Sorry all, for the large number of posts by me, but I have waited a long time for fresh in situ decent data from the Jovian system. New Horizons has delivered & delivered well. A real big kudos to Alan Stern & his team. Reposted as original image did not work properly (very grainy).

These high velocities are great for obvious reasons but there is one drawback: orbital insertion becomes more difficult, can't carry enough fuel for braking, especially at a low gravity target like Pluto, so you're limited to flybys, some future Pluto orbiter would have to be rather massive, I can't wait for ion drives to become standard.. <div class="Discussion_UserSignature"> </div>
