The Best Of Planetary Explorers 143

An anonymous reader writes "NASA's timeline is published today on the top seventy five events in recent planetary explorations. Since June and July inaugurates three new landers going to Mars, it is curious to see their selected images: Venusian crust hot enough to melt lead, comets colliding with Jupiter, Europa's frozen ocean. But the most precious discoveries may be those chalked up as nearly free riders: the fifteen Mars rocks that annually are found among Antarctic meteors [100 grams total] and all those four and half million personal computers doing SETI@home CPU cycles."

      I think SETI@Home has been successful at something many of these other events also achieved -- capturing the imagination of the populace.

      I remember as a child, reading magazine articles about the moons of Jupiter, seeing an artist's conception of Jupiter rising behind a Volcano on Io, and being flabbergasted ... awestruck.

      Whether it was picturing running on the moon in the low gravity, or gazing out the window at Jupiter as a passenger spaceship did a loop around the gas giant on its way to an unknown destination, my imagination was completely dedicated to space travel.

      Years later, I run SETI@Home for the same simple reasons. The thought of having some small part in what could arguably be the biggest discovery ever ... that's something.

      If SETI@Home never finds anything, it has still succeeded in giving me some measure of joy and excitement, that I'm doing my own small part.

      Perhaps the strongest result to come out of SETI@home is the validation of a new means of performing research, i.e. the distributed computing model. SETI@home took that model and rolled it out into the public domain where everyday people could become a contributing part of research.

      It depends how big the chunk is. Basically, the impact needs to accelerate the "chunk" form zero to escape velocity. Escape velocity is the same for everything (it only depends on the earth's mass and the distance from the centre of mass) but varies very very very slightly with height. How much of a push your chunk needs depends on its mass.

I mean, something like 90% of the stories on this site revolve around how perfection in automation is practically impossible to achieve. About how, a certain level of bugs is to be expected no matter how much the software is tested.

      What, exactly, makes you think that NASA has some sort of secret magic bullet that they're not telling us about? What's the reason for the space shuttles carrying astronauts? Because automation is unreliable, at best.

      The scientists at NASA don't just sorta guess. They make educated guesses. Sometimes those guesses are wrong. The stuff we don't know about flight at the kind of speeds would shock you. (Try googling for "real gas effects" or "radiation heat transfer" together with "re-entry" if you're interested.) For instance I believe that on the first shuttle flight the prediction of center of lift was off by 0.7%, necessitating doubling the flap area.

    I grew up in a small, conservative USian town and so the education that we got about space exploration was exclusively about USian missions (in fact, the school board prohibited the teaching of information about Soviet successes since they deemed such information to be unpatriotic.)

    But the fact of the matter is that the Venera landers were a marvel of human engineering. They were able to touch down on the planet's surface, take instrument readings, and even return pictures of the planet's surface and skyline .. all of this in an environment where the temperature is 900 degrees (Fahrenheit), the atmospheric pressure is 100 times what it is on Earth, and it rains sulfuric acid. The Venera landers only operated for a few minutes each, but it's a wonder that they were ever able to operate at all! Mars looks like a cakewalk by comparison.

        There are even MORE books and even MORE links to web-sites proving the contrary. The proof offerered as to the moon landing's reality far, FAR outweigh those of the skeptics. This is a no brainer.

        I have researched every single claim of the "faked moon landing" people, and have not found ONE that wasn't explained rather simply. In fact, there are dozens of things that show this was done on the low gravity surface of the moon that CANNOT be explained by any artificial means. Look at the moon dust fly up from

    Oh dear, I hear some criticism of both NASA and the SETI project. Though most space exploration is driven by military-industrial interests (lots of pork; forget projects like "Star Wars" - think space-based offensive nuclear capabilities to ensure a quick-strike), SETI is interested in a more noble pursuit: are we alone? Absence of evidence is not evidence for absence (to quote Ellie from the movie Contact, "You know, there are 400 billion stars out there, just in our galaxy alone. If only one out of a million of those had planets, all right, and if just one out of a million of those had life, and if just one out of a million of those had intelligent life, there would be literally millions of civilizations out there.."). Think about the dramatic changes that the discovery of intelligent alien life might bring about. Isn't that justification enough? Humanity might even be mature enough to handle the enormous cultural differences that typically lead to conflict whenever societies foreign to each other meet. Maybe. All of this doesn't even take into account the technological improvements that result from us rising to the complex problem of space exploration. For instance, SETI@home is a model example for distributed data processing if I ever saw one. Money spent here has some positive feedback for the economy, whereas money spent on long-term welfare provides little to none (not to mention sustaining unhealthy behavior on the part of the citizens). Plus, I want to know if aliens talk and look like the stuffed ones from Toy Story, or breathe methane gas and communicate using olfactory stimulus. Talk about a hard language to decipher. ;)

    In the next decade we will see the first of a totally new class of orbiting space telescopes - large arrays of sensors spanning many tens of miles across. These will be true orbiting interferometers [space.com] which will bring amazing optical resolution to "near-earth" explorers.

    The ramifications for earth-based planetary exploration are huge. Currently, work is being performed on how to keep such a satellite array in perfect alignment. Low-thrust ion engines and tide-stabilizing configurations are flying as we speak.

    NASA has plans to launch the first Space-Based Interferometer [nasa.gov] in 2009. Taking into account the inevitable schedule slide, we should start seeing some really cool pictures in about 2012. AND, since the array will live relatively close to our "Big Blue Marble," it might also be a reason to keep the ISS and the manned space program in general running for another decade. All it takes is $$$$$$$$$$$$$$$$$$$.

  • Surely, one of the greatest events of the last quarter century of planetary exploration was the launch of the first element of the International Space Station. It's the next logical step to the rest of the solar system.

    NASA says it, so it must be true.

    There's some good stuff listed there, and some sad failures too.

    I remember hearing about Shoemaker-Levy 9 and thinking "oh, that's gonna be so frickin' cool." When the time came, I was watching TV, and one of the NASA people was handling a press conference. Someone asked a question about what we should expect to see. Her answer was along the lines of "well, a lot of predictions have been made; some simulations suggest could see quite a spectacular plume, but it could be more subdued, me might not get to see much..." Before she got a chance to finish, an astronomer came out with a couple of bottles of champagne grinning from ear to ear. When the first pictures started showing up, my hair stood on end.

    It makes me sad that so few people can appreciate magic moments like this in science. Instead they turn to pseudoscientific herbal bullshit about holistic medicine, astrology, dowsing, planet X, moon hoaxes, remote psyhic viewing or past-life regression. There are a lot of good people out there working hard to bring real knowledge about the universe to all of humanity. Nothing good has ever come from a snake-oil salesman.
