Cassini Alters Path. Phoebe Now In Sight! 186

Anonymous Explorer writes "This week the Cassini-Huygens Spacecraft finally entered the Saturn system and made its first main-engine burn in five years in preparation of for the Phoebe flyby. This long journey has been one filled with much promise and peril. Launched in 1997, Cassini is expected to have a rendezvous with the moon Phoebe on June 11. For those of us who are lazy, that's just a tad under two weeks away. After the Phoebe flyby, it's on to the ringed planet, with an anticipated July 1 ground orbit insertion. The ESA's Huygens probe will descend into the atmosphere of Titan a few months after Cassini is inserted into orbit. This mission promises to be one that brings a very psychedelic and beautiful area of our solar system into clearer focus. This multinational mission is one the most ambitious scientific explorations yet undertaken and promises some truly otherworldly images in the near future. With 31 moons/natural satellites thus far discovered orbiting Saturn, there should be a lot to keep us occupied. Anyone else excited about the journey to a ringed world? Lets all enjoy this ride. It promises to be a unique one as much as for the scenery as for the science. Informal discussion regarding the Cassini-Huygens mission can be found at #cassini on irc.freenode.net."

      The protests were about a risk, that is, an accident that could have occurred with a certain probability. Everybody pretty much agreed that the risk of an accident was at least fairly low. What people disagreed on was the cost should such an accident acctually occur. The fact that a fairly low-risk event didn't occur does not tell you anything about whether it was prudent to engage in the activity in question.

      I'm sorry that such elementary scientific and economic concepts as "risk" and "cost" elude you. Without an understanding of those concepts, you are simply in no position to even participate in such debates.

        I call troll.

        It seems that you don't understand the concepts of risk and probability.

        You never have a "certain probability". All you have is probability. Probability is a best guess in cases such as this since there are numerous factors to take into consideration.

        72 lbs. of plutonium re-entering the atmosphere BY ITSELF without shielding would cause insignificant damage at best. It would be vaporized and scattered in the upper atmosphere, where cosmic radiation would rapidly turn most particles into unstable elements that breakdown even faster.

        In fact, the chances of said particles reaching the surface of the earth is minimal. And even if it did, we are talking fractions of microcuries at best.

        BUT IT WILL DAMAGE THE ENVIRONMENT! 36 kg of plutonium vs. 6.14X10^24 kg of Earth? With the way people make radiation sound, you'd think it was magical death wraith just waiting to be set loose on the poor undefended Earth.

        And while we're talking about probabilities, I think you should be more concerned with your fellow drivers than an errant space probe. You're far more likely to die in a car crash than any sort of radioactive accident, least of all from a space probe.

        To put it in perspective, you have a risk when you take a shower in the morning. There's a risk that you could slip, crak your head and die. The risk is small, but it's there. Does this mean you shouldn't take showers? Do you do a risk/cost analysis everytime you step in the shower? Do you have life insurance, a will, savings, etc. for anyone left behind? Do you estimate how much a funeral will cost? What taxes will be due? How much lawyers will cost? What about your job? The cost it would take to replace you? The list goes on. And this is all just based on you taking a shower.

        Do you trully know your risk/cost? I doubt it. It's not possible to know all the repercussions of your demise because no one can predict the future. If you were smart though, you would be prepared as you could be for such a thing and you'd go on living your life and taking showers.

        You're just one person. NASA has hundreds who run computer simulations, analysis, environmental impacts, emergency scenarios, etc. . The probe was launched in 1997, but they were probably testing the hell out of it for at least a decade. And NASA has been doing this since the 60's.

        They are not infalliable, but they have numbers to back up their claims. And I would take a 100 scientist recommendation over an elitest snob.

        • My point was, clearly stated, that people generally agreed that the probability of an event was low, even people who opposed the Cassini launch. Therefore, absence of an event does not prove, as the post implied, that the launch was low risk because the event itself was low probability.

    It's gonna be nice to see a photo-intensive orbiting mission to one of the big gas giants. The Galileo orbiter for Jupiter had an antenna problem that greatly reduced the imaging volume.

    However, based on Voyager flybys, Saturn's moons are not quite as photogenic as Jupiter's. Titan is covered with a thick feature-poor haze and most of the other moons are too small to have many of the interesting tidally-caused features of the Jupiter moons. But there are still some interesting features on some of the moons.

    And, Cassini will drop a probe into Titan's atmosphere that should return some interesting images and data. Titan may have a methane ocean and the Titan probe may possibly land in it and float for a few hours. The ocean may have giant waves because the gravity is so weak compared to Earth, similar to the way that sand-dunes are easier to make on Mars because of the lower gravity there. Things can get taller and weirder under low gravity. It would be the first time liquid could be seen from the surface of another world (aside from the Apollo Tang drippings).

      Photographic indeed. Take a look at the DISR [arizona.edu] page that details the optics and detectors that are aboard the Huygens probe. There are even some test images [arizona.edu] taken with the flight spare that give an idea of the images to be returned from the surface of Titan (sans palm trees perhaps). Huygens is expected to relay ~175 MBytes of data through Cassini and back to Earth for a nominal mission, this is almost 500 TIMES the total data returned from the Galileo atmospheric probe!! There are many other experimental devices attached to the bottom of the probe which are beautifully elegant in design that will tell us about just what it hits when it gets to the surface ice...liquid hydrocarbons...etc. The surface science package also contains a piezoelectric transducer to determine the depth of the ocean it may land in using sonar pulses. It can measure the height of waves on the surface with its accelerometers and the density of the liquid with a refractometer to determine the liquid's index of refraction. The amount and quality of information retured from the dim frigid surface of this strange world hundreds of millions of miles away will be positively awe inspiring.

      Judging from previous releases from the imaging team(CICLOPS [arizona.edu], they seem to be a very, very competent bunch. During the Jupiter flyby 4 years ago, they used the spare seconds between scheduled observations to take extra images of Jupiter in true color which they then stitched together later to form the highest detailed full planet image of Jupiter ever taken [nasa.gov]. With Cassini actually passing through a gap in the inner rings during its orbit insertion it's hard to imaging the spectacular images that await us.

      June 30 is the real show when Cassini performs its orbit insertion burn for over 90 minutes, resulting in a delta-v change of in the area of 1,400 mph.

      What's remarkable is that because of the distance between Earth and Saturn, there is an hour and 20 minute lag, so Cassini is pretty much on its own for this (and most other) maneuvers.

      Amazing indeed, but they can do even better. Just look at the Voyager spacecrafts, they've been out there since the 70's and the reason they will be shut down within a few years is because they're running out of power, rather than hardware failure or something.

      Although one of the Voyager probes [nasa.gov] whizzed through Saturn's ring plane (which is only about a km or so thick), no such daring maneuver is planned for Cassini.

      There is a preliminary plot of Cassini's possible orbital tour here [nasa.gov]. According to it, Cassini will make around 69 orbits during its planned mission. Note that one of Cassini's primary targets, Titan, orbits at around 40 Saturn radii, well outside the rings.

      Oh, and, look for all the pretty pictures from Cassini to be posted over at CICLOPS [arizona.edu] (Cassini Imaging Central Laboratory for Operations).

        The ring plane extends out to infinity, and so even the Earth passes through it occasionally. The ring plane is considerably tilted with respect to the ecliptic, so it would have been impossible for the Voyagers to not pass through the ring plane. Both went well outside the rings, not, as you imply, through the rings (In Saturn radii: closest approaches V1=3.09 & V2=2.67, outer ring lies at ~2.3) Someone has already pointed out your misinformation about the Cassini orbit.

    When do they get pictures of Rachel? That would be some moon! I like that one better than Phoebe, at least to look at, but Phoebe is more entertaining to listen to. You can skip Ross, Joey and Chandler but take a few of Monica mooning while you're at it. That will get me excited :).

    ... about the journey to a ringed Apparantly not, we're having the same old discussion about that hazards it posed for having a nuclear power source, and dumb jokes about a character on a defunt sitcom. Perhaps it would save some bandwith on /. if mods just decided to forgo future Cassini stories. Those who want to see the pictures know where to go.

    For those of you interested in Saturn's larger roll in the formation of our solar system, check out this site. Lots to read, but pretty interesting:

  • Things like this are among the things that move our entire world forward. Maybe not as big as landing on the moon within ten or anything...but, we are about to plunge a highly sensitive instrument into the atmosphere of a moon that is a solid distance away. It amazes me sometimes what we as a race are able to create and act upon. Our thoughts coming to fruition. This is the type of advance that could show us life. As I have said before...that time when we do discover and know of the existence of a growing

    Just out of curiousity: The pics show that the rings cast shadows on the surface of Saturn. I wonder what it would look like if you were on the surface of Saturn, and would be in an area covered by ring-shadow. Is the light just more dim, or would it be completely dark? And would the rings be visible through the atmosphere (in both shadow or light)?

    Hmmm how about an artist-impression of that... :-)

    We have a room on the irc.freenode.net servers called #cassini which is available to all who are interested in the Cassini [nasa.gov] project. Here you will find a wide range of interests discussed, from the informal to the most scientific details of the mission. Some of the Cassini staff have shown interest in participating to further support the project's public interest so don't be surprized to meet them there.

    We also support the ' Maestro [telascience.org] ' program which is the Public-Outreach software [telascience.org] created for the Mars Exploration Rover Project [nasa.gov] from JPL [nasa.gov]. As a result, we helped maintain the #maestro room (also on freenode.net) which is still in operation today.

    With such high interest building as Cassini-Huygens [nasa.gov] approaches orbital insertion and the Phoebe flyby, we expect a bigger rush in the next weeks. Join in and share the experience!

    If you are not sure how to do 'IRC' there are many good primers [irchelp.org] online to help and you can visit http://freenode.net [freenode.net] for details about connecting as well as links to assist you to set things up to chat online.

    See all "/.'ers" there... ;^)

  • The submission isn't really wrong, 5-6 months could still be considered a 'few' months but the Huygens probe [nasa.gov] won't be released until December, 2004, and won't reach Titan until January, 2005.
