Re: E-Mails from the New Horizons Folks

Yeah it does seem almost anticlimax that after 9 years of travel it will blast past Pluto without slowing down... but it was really also designed to poke around the area past Pluto's orbit as well. I think there will be interesting discoveries made out there.

Pluto Mission News

A Summer's Crossing of the Asteroid Belt
June 1, 2006


May, like April, was a busy month for New Horizons instrument payload commissioning. In particular, our instruments LORRI, PEPSSI, Alice and Ralph all continued their in in-flight checkouts. In addition, the spacecraft itself received a new suite of onboard fault protection autonomy software resolving a number of bug fixes discovered in ground and flight tests. We continue to see software-induced guidance computer resets once or twice per month, but the spacecraft recovers flawlessly from these, without any interruption to plans. The team is working on software that will resolve the bug that causes this; we expect to have that load tested and aboard the spacecraft around Oct. 1.

Highlights of our payload commissioning activities included door openings for PEPSSI (May 3), Alice (May 20) and Ralph (May 29). The Student Dust Counter (SDC) registered each of these events at the precise time of the door openings by the noise they made on the spacecraft. Each of these instruments also saw "first light," i.e., detecting signals from stars (Ralph) or the interplanetary medium (PEPSSI and Alice). From these tests, we appear to have a little higher than spec sensitivity with Ralph's color and panchromatic cameras. Also, Alice's background counts are only about half what we predicted, indicating that the Radioisotope Thermoelectric Generator (RTG) induces a significantly lower background than we estimated before launch. This lower background rate will significantly enhance Alice's signal-to-noise ratio on faint spectral features.

From the Alice, Ralph and PEPSSI testing this month we can say that from all of the data surrounding the careful, step-by-step instrument commissioning activities to date, our instrument payload continues to perform as well or better than predicted from ground testing. This is a testament to the exacting engineering that went into their development.


In other news for May, we began to finalize the suite of observations planned for next year during our Jupiter flyby, and we continued to track New Horizons to determine whether a fine course correction will be needed this fall. So far, no course correction appears necessary, but the final verdict won't be in until we have about another 90 to 100 days of tracking.

Planning activities began in May for the annual 60-day checkouts we'll perform each year each year during Cruise 2 ("Glen's Glide") - the coast from Jupiter to Pluto. From 2008 to 2011, these checkouts will occur in the fall. But from 2012 to 2014 our annual checkouts will occur in the summer, because we'll be rehearsing the Pluto encounter aboard the spacecraft and we want the Earth-Sun geometry at rehearsal time to faithfully reproduce what will occur at the actual encounter in summer 2015.

Now let's talk about the significance of our current location: deep in the solar system's asteroid belt. As both the title and the first illustration in this month's blog indicate, we're traversing the main asteroid belt now. This region of the solar system consists of a handful of dwarf planets, like Ceres (itself 1,000 kilometers in diameter), and literally millions of debris bits created by collisions between asteroids. These small bodies range up in size from mountains to objects as large as 100 kilometers across. The asteroid belt also contains innumerable boulders, rocks and dust motes created by the same collisions. There are many good Web sites describing what is known about the asteroid belt. One I hope you'll like can be found at: http://www.solstation.com/stars/asteroid.htm; another good site is http://en.wikipedia.org/wiki/Asteroid_belt.

The first spacecraft to transit the asteroid belt was NASA's Pioneer 10, which made its epic crossing in 1972 on the way to the historic first encounter of a spacecraft with Jupiter. Later, Pioneer 11, Voyagers 1 and 2, Galileo, Cassini, NEAR and Ulysses all made the same kind of journey to or across the main belt. Now it is our turn. Fortunately, the asteroid belt is so huge that, despite its large population of small bodies, the chance of running into one is almost vanishingly small - far less than one in one billion. That means that if you want to actually come close enough to an asteroid to make detailed studies of it, you have to aim for a specific asteroid.


The first such asteroid flyby was made by Galileo in October 1991. Galileo also made a second asteroid encounter in 1993. Other spacecraft, most notably the NEAR (Near Earth Asteroid Rendezvous) mission, have also made close main belt asteroid flybys, yielding important geological and geophysical insights into these bodies. Galileo also made the first discovery of an asteroid satellite in its 1991 flyby of asteroid Gaspra -since then, ground-based observers have found dozens of asteroid satellites. In addition to main belt asteroid flybys, NASA's NEAR and the Japanese Hayabusa mission have both made orbital rendezvous and landings on asteroids closer to Earth. And next year, NASA plans to launch the Dawn (http://dawn.jpl.nasa.gov) Discovery mission to orbit two of the largest asteroids - Vesta and Ceres. Dawn will arrive in orbit about Vesta in 2012, and will reach Ceres, the largest asteroid, in August 2015, just a month or so after New Horizons encounters Pluto.

A long time ago, we considered the possibility of targeting a close asteroid flyby with New Horizons during our crossing of the main belt. As the mission PI, I rejected this early on for two reasons. First, such an encounter would take about half of our Kuiper Belt fuel to accomplish. Secondly, even for this amount of fuel, the only asteroids we could hope to reach would be tiny - just a few kilometers across. While such an encounter would certainly be scientifically useful, it couldn't be justified for the amount of Kuiper Belt fuel it would cost us. And when all is said and done, our job is to reconnoiter bodies in the Kuiper Belt.

Although we specifically decided not to target any asteroid, after launch we did conduct a thorough search for chance encounters along our trajectory. Just the statistics of such chance encounters indicated that we might expect to pass perhaps 1 million to 3 million kilometers from a small asteroid by chance as we transited the main belt. We found several such opportunities back in February.

But, as it turns out, we got more than what we expected: in early May we also discovered that we'd pass within approximately 104,000 kilometers of the little-known asteroid 2002 JF56 on June 13! This little mountain-sized body (http://smass.mit.edu/2002jf56.html) is only 3 to 5 kilometers across; virtually nothing is known about it - not even its compositional type or its rotational period.

Although we cannot resolve something as small as 2002 JF56 from this distance with Ralph (LORRI, which has higher resolution cannot open its door until late August to guard against accidental Sun pointings), the June 13 "encounter" with 2002 JF56 is still going to be useful to New Horizons.
The primary use of this distant flyby will be to test Ralph's optical navigation and moving target tracking capabilities. We will also get a handle on the asteroid's light curve, composition, phase curve, and perhaps even refine its diameter if all goes as planned. But this event is really a flight test, so we aren't guaranteeing anything but a best effort. If it works, you'll see images that just barely resolve the asteroid into perhaps 1 or 2 pixels and perhaps a spectrum of this chip off some larger body. More importantly, of course, we will gain some valuable experience that will yield benefits at both the Jupiter and Pluto flybys, so we're excited to give this a try.

Stay tuned, we'll report on the results at mid-month on this Web site.

Flight activities for June will center on SWAP instrument testing, Ralph instrument calibrations, and beam mapping observations for our high gain antenna and REX (radio science) instrument. By July 4, we'll be 3 Astronomical Units (AU) from the Sun. Although the sunlight there is still 100 times as strong as it is on the brightest day at Pluto, it'll be about 10 times dimmer than at Earth's orbit. Less than six months into a 114-month journey to Pluto, New Horizons is beginning to reach the cooler thermal conditions it was designed to thrive in!

Well, that's all I have for you for now. So until next time, keep exploring.

Pluto Probe Passes An Asteroid

June 15 , 2006
New Horizons Tracks an Asteroid

It's a small object with big news for the New Horizons team: the first spacecraft to Pluto tested its tracking and imaging capabilities this week on asteroid 2002 JF56, a relatively tiny space rock orbiting in the asteroid belt.

In photos snapped by the Multispectral Visible Imaging Camera (MVIC) component of New Horizons' Ralph imager, from distances ranging from 1.34 to 3.36 million kilometers (about 833,000 to 2.1 million miles), the asteroid (with an estimated diameter of about 2.5 kilometers) appears as a bright, barely resolved pinpoint of light against the background of space. That Ralph "saw" the asteroid demonstrates that it can track and photograph objects moving relative to New Horizons - just as Jupiter and its moons and then, later, Pluto and its moons will be. This capability is critical as New Horizons closes in on Jupiter for a gravity boost toward the Pluto system.

"The asteroid observation was a flight test, a chance for us to test the spacecraft's ability to track a rapidly moving object and to refine our sequencing process," says Gabe Rogers, New Horizons guidance and control engineer from the Johns Hopkins University Applied Physics Laboratory, Laurel, Md. "The objects we will observe this winter in the Jupiter system will appear to be moving across the sky much more slowly than this asteroid, so these observations were an unexpected opportunity to prepare for the even faster tracking rates we'll experience in summer 2015, when the spacecraft zips through the Pluto system at more than 31,000 miles per hour."

Ralph's camera took separate images on June 11, June 12 and June 13. The images had to be compressed (to save on the number of bits that must be sent back), radioed back to Earth through NASA's Deep Space Network of antenna stations, and checked out by mission team members before they could be evaluated.

About an hour before closest approach to the asteroid - which occurred at 4:05 UTC on June 13, at distance of 101,867 kilometers - Ralph began scanning it to obtain color images and infrared spectra. Those data must also be compressed before they're sent back to Earth next week.

"Ralph has performed flawlessly since the launch of New Horizons and these asteroid observations are giving us more insight into the ultimate sensitivity and capability of the instrument," says Ralph Instrument Scientist Dennis Reuter, of NASA Goddard Space Flight Center, Greenbelt, Md. "They are allowing us to use Ralph to view and track a single fast-moving object as it changes from a dim speck of light in a bright star field to a body whose brightness rivals that of Jupiter at the high resolution that Ralph is capable of."

Launched last Jan. 19, New Horizons is currently 283 million kilometers (176 million miles) from Earth, moving about the Sun at about 27 kilometers (17 miles) per second. The spacecraft is on course to fly through the Jupiter system for science studies and a gravity assist, with closest approach to the giant planet set for Feb. 28, 2007.

LOL Fortunately there are no traffic cops out there. The New Horizons probe is the fastest man made device ever launched. The Pioneer and Voyager probes to Jupiter used to be the fastest devices at about 39k mph, but Pluto is a good deal further away than Jupiter. The Jupiter pass mentioned in the article is designed to sling the NH probe around the planet with two purposes: one to adjust its course towards Pluto, and second to increase its speed by some 9000 mph without having to fire its on-board thrusters. This "slingshot" maneuver was successfully used by both the Pioneer and Voyager probes to send them to Saturn, Uranus and Neptune.

Pluto New Horizons Probe: All Instruments Functioning

If you have been reading the posts on this subject for the last few months, you'll recall that the NH team have been activating each of the instruments slowly, one at a time with the last one being the hi-resolution imaging system called LORRI. It was necessary to keep the LORRI camera covered until the probe travelled far enough that an accidental pointing at the Sun wouldn't destroy it. Well, Sept 1 was the day that LORRI saw "first light", which means that all the New Horizons's systems are healthy and the probe is fully functional. Now the next major encounter is the Jupiter slingshot maneuver next February which will adjust it's course and add almost 10,000 mph to the probe's speed towards Pluto which will occur in 2015. "Dwarf planet" or not, this is the first time any man made instrument package has visited Pluto. The NH team is happy that their little robot is working and so am I.

Here's the official New Horizons press release:

LOL I know what you mean. As fast as that little robot is travelling, 9 years isn't really too long. I find it amazing to consider that the Apollo missions took 3 days to get to the Moon, while NH passed the moon in 9 HOURS! Of course the big difference is that NH didn't have to slow down because the Moon wasn't its final destination.

FYI, as of 9PM Central time, the NH probe is over 364 million miles from Earth (596 million Km) with a mere 2,700 million miles (4,300 million Km) to go. It's travelling at over 52,000 miles per hour (84,000 Km/h). When it does its Jupiter swing-by at the end of Feb 2007, an additional 9,500 mph (152,000 km/h) will be added to its speed.

I'm thinking that if a more efficient and powerful propulsion system is designed in the interim, it would be sadly ironic if the NH probe is overtaken by a more advanced probe. That's not at all likely to happen, but it's still funny to consider.

No excuses... I fucked up and I thank you for catching that.

Simple, mistake man not a problem That's really cool, I used to be very into spacecraft and missions, until I saw species when I was about 12-13. Kinda spoiled the whole alien thing for me.

Yeah, that would just about do it. I actually paid to see that abortion in the theater. One of the worst movies I ever saw-at least until I saw the latest Star Wars cac

However, a shitty movie shouldn't put you off the excitement of the real space exploring that is going on. There's the Cassini probe in the Saturn system, the Venus Express that just arrived, the Mercury MESSENGER probe en route, and of course all the machination on or around Mars. Lots of stuff going on IRL. Let Hollywood have their crappy fantasies; I'll stick to the real thing.

Jupiter Ahoy!

Blazing along its path to Pluto, New Horizons has come within hailing distance of Jupiter. The first picture of the giant planet from the NASA spacecraft’s Long Range Reconnaissance Imager (LORRI), taken Sept. 4, is a tantalizing promise of what’s to come when New Horizons flies through the Jupiter system early next year.

LORRI snapped the image during a test sequence to help prepare for the Jupiter encounter observations. It was taken close to solar opposition, meaning that the Sun was almost directly behind the camera when it spied Jupiter. This makes Jupiter appear blindingly bright, about 40 times brighter than Pluto will be for LORRI's primary observations when New Horizons zips through the Pluto system in 2015. To avoid saturation, the camera’s exposure time was kept to 6 milliseconds. This image was, in part, a test to see how well LORRI would operate with such a short exposure time.

“LORRI's first Jupiter image is all we could have expected,” says LORRI Principal Investigator Andy Cheng, of the Johns Hopkins University Applied Physics Laboratory, where LORRI was designed and built. “We see belts, zones and large storms in Jupiter's atmosphere. We see the Jovian moons Io and Europa, as well as the shadows they cast on Jupiter. It is most gratifying to detect these moons against the glare from Jupiter.”

Re: Jupiter Ahoy!

Jupiter is my favorite planet by far. I could (and have) watch(ed) the swirling patterns of gas undulating and coalescing for great lengths of time.

And Jupiter also has my favorite satellite. EUROPA!!! BLIND SHARKS MUTHAFUCKAZ!!!

No but seriously, there had better be some blind sharks on Europa. And I wonder how they taste. Grilled teriyaki Europan shark steak anyone? I make an excellent shark soup as well.

New Horizons promises a lot. I sure hope it will deliver.

Re: Jupiter Ahoy!

The science and observations NH will be doing during the Jupiter Pass are only "opportunistic". The real reason NH is coming so close to Jupiter is to use Jupiter's powerful gravitational field as a giant slingshot to pick up almost 10,000 mph of free speed so NH won't be in the neighborhood for too very long at all.

As far as the possibility of your blind Europan sharks go (frankly, as nonscientific as this sounds, I have very little doubt that there is life of some sort under that icy skin of Europa) ...recall my "Space and Stuff" podcast and consider what I said about the "black smokers" on Earth. The bottom of the food chain in those microclimates are SULFUR consuming organisms. If the blind sharks you (and I) so fervantly wish to see in the Europan waters have even a similar biochemistry, I very much doubt that they would be palatable to us. I don't think I'd find a cut of fish loaded with sulfur compounds very tasty. Even if we got past the egg fart smell, they would probably be quite toxic to us anyway.

Re: Jupiter Ahoy!

If there has been a fairly stable environment down there on Europa for as long as most scientists tend to agree, those hydrothermal vents (AKA "black smokers") are hosting a lot more than just bacteria. A billion years of stability means a billion years of evolution of more complex forms. If there is something that eats, there is also something larger that can eat it. Seeing as how the ice is many miles thick over the waters of Europa and the sunlight is many times fainter out there, the chances of the oceans being totally dark is very good. Any life forms which evolved there did so without light so have no need for eyes. The food chain has to have a top predator- hence the blind sharks

Re: Jupiter Ahoy!

bioluminescent creatures...

yeah, i dont think sharks or other animals as complex as they are but who knows...you're gonna need a big drill to find out.



ps. does anyone want to write an aurgumentative essay on niccolo machiavellis 'the prince' ? :-D

Re: Jupiter Ahoy!

Concerning the exposure time, I was under the impression a shorter exposure time would be better when light is sufficient (disregarding CCD burnout). If I recall, the Voyager spacecrafts had some problems because they needed a long exposure time at such large distances. The problem was that the small vibrations blurred the images (like shaking hands when taking a picture indoors). This was supposedly solved by taking a series of images with short exposure times and using visible light interferometry to combine the images. I don't know enough about New Horizons or LORRI to know if they will use the same technique.

Voyager used 1970's era cutting edge technology which I suspect is just short of daguerrotype compared to the cutting edge imaging systems which exist now. Also, the primary optics of the LORRI imager is an 8 inch telescope because LORRI is designed to image a far far dimmer object than Jupiter. Like I said, the Jupiter science is opportunistic. NH is a creature of dark, cold space. Jupiter is next door compared to where New Horizons is heading.
