Nerds! Darpa Wants Your Advice on Interstellar Flight
"Remember how you read those issues of Silver Surfer from
the 60s and reflected long and hard about the possibility of pacifism when all an intergalactic traveler encounters is warlike aliens? The mad scientists at Darpa want you to put those musings to advise its most cosmic project yet. Darpa recently launched a program called the 100 Year Starship, which is exactly what it sounds like: an effort to achieve interstellar flight by the year 2111. This being Darpa, they’re dead serious. And they also recognize that 2011-era technology probably isn’t good enough to forecast the state of the art over the next 100 years."

See: http://www.wired.com/dangerroom/2011...-advice-on-int erstellar-flight/ Why would it take 100 years to design and build an interstellar spacecraft? It depends on how fast you want to travel (and then, perhaps, stop at the destination). If you only want to travel at 0.1% of Light, it should be easy enough, but take 430 years to get to Centauri. So, what mission time-line are the thinking of? Maybe it will take that long to reverse engineer the Roswell (and other) craft. ;) |

But this gives me the perfect opportunity to present my "Vegative Starship" concept to them: http://groups.google.com/group/rec.a...2dbce274268532 "I hereby nominate my idea- The "Vegetative Starship": a truly wonderful device that puts starflight within our reach even today - as any good medieval herbalist knows, each species of plant has a affinity for a certain star, whose influence draws its sprout forth from the soil after it germinates...this is a small, but very real, force, which like an ion engine can generate a great deal of velocity over a period of time - the Vegetative Starship resembles one of the greenhouse domes off of the "Valley Forge" of "Silent Running" fame. It is assembled in GEO, and its crew of carefully selected award-winning gardener/scientists put onboard...then the planting of the correct type of plant for the target star ensues - the domed top section of the ship is aimed toward the destination, and the seeds begin to feel the influence of the distant target sun - but as they try to draw themselves toward it with their sprouting, their roots are locked squarely into a artificial soil matrix screen, and they begin to slowly pull the whole ship along with themselves as they are drawn starward - bit by bit the speed increases as the plants continue to grow (if in a somewhat stunted state, due to the acceleration of their garden environment) and after two or three generations have been planted, the ship is moving at a good fraction of lightspeed - now the plants are harvested for the last time, and another species sown, which has an affinity toward a star at the antipodes of the celestial sphere, thereby braking the starship's velocity and allowing it to enter orbit around it's destination...other species of plants can be planted in small amounts to serve as a maneuvering system for the ship changing its attitude and modifying its trajectory as they are moved around in its interior and are attracted to their kindred stars. But one of the real advantages of this type of starship is that it's self homing; pick the correct species of plant, kick back, and let mother nature do all the work...no fuss, no muss...and no annoying, almost weekly, imminent breach of the matter/antimatter containment field! ...and, with a little forethought and careful choice of destination stars, edible species of plant can be used, and sustain the crew with their harvesting and oxygen producing ability. "Ad Astra Per Asparagus" may well be the motto of these harvesters of the heavens; these gardeners of the galaxies; these sower's to the stars! But we must ask ourselves...is there anything wrong with this idea? Is it perhaps unworkable? I need only point out one staggering argument in its favor- I mean of course - that Great Enigma; That Mysterious Manuscript; That WONDER Of WONDERS...THE VOYNICH MANUSCRIPT! LOOK AT THIS, YOU DOUBTING SWINE!!!!!!!!!* http://www.crystalinks.com/voynich.html An entire book of star charts, written in a language no one has ever been able to decipher, with loads of pictures of plants no one has ever seen on Earth....and, as a special bonus, and incentive to make you look at the site above...PICTURES OF NAKED LADIES ALSO! Naked Ladies that were probably being lusted after by some priapic aliens in a Vegetative Starship when they dropped by our Solar System round about 1400 or so, sick and tired of having eaten Sunflower Seeds for twenty odd years (One of the few plants that IS recognizable in the manuscript is the Sunflower; now revealed to be a Triffid-like contaminant upon our blessed Earth, and most aptly named; for this was the fuel that brought these adventurous Botonauts to our planet - you will note that there is no mention of the Sunflower plant in the Holy-Bible-Book, sure proof that it didn't exist on Earth until it was brought here!)- they got drunk, got laid, and lost one of their tech manuals, as they puked their hung over way back into the sky.... ready to eat grass for the next twenty years, on their way to the star Aldebaran...in Taurus the Bull. " * I may take that part out of the DARPA submission. Pat |

It's not just about how you build a starship.
You need to read what DARPA and NASA Ames have put out. A starship project would cost (using the midrange estimate from the Icarus group) some $20T. You can't simply treat that as another engineering project: no agency in the world can raise that kind of money for a space program. DARPA asks how you could create an organization which, over the notional century-long period, could evolve the technology, society, and economics needed to create an interstellar spacefaring civilization. In other words, how do we encourage a long-term effort whose scope needs to be global? Matt Bille www.mattwriter.com |

I think DARPA trying to work out something a hundred years in the future is about as futile as trying to predict what our technology would be today back in 1911. Here's what spaceflight in the future was thought to look like in 1914-1918: http://modcult.org/image/1392 ...when giant airplanes that could fly at 120 mph set out for the planets. Pat |

The largest space organization in the world today has a budget of
$18B, out of which only a few billion is available for exploration. A global effort creates all kinds of headaches and will require some really innovative thinking. Certainly no current international organization is up this challenge. But that's DARPA's point in specifying it wants organizational and political and financial, not just technical, solutions: we can't just solve the workings of a Bussard ramjet or whatever. Solving the riddle of how to get governments, corporations, and NGOs on board a century-long effort to transform us into an interstellar civilization will be the most difficult thing in the history of the world. But it's still more likely to work than getting any one nation to devote an average of $200B a year. We as a species have to WANT to do this. It's a challenge with as much in common with the great religions as with Apollo and ISS. It's the sheer audacity of the thing that makes it beautiful. Matt www.mattwriter.com |

See: http://www.wired.com/dangerroom/2011...tellar-flight/ Tell them not even to think about it. There's nothing the big aviation manufacturers would like more than a project where they're not required to deliver within the lifetime of most humans. A perfect excuse for being paid for activity rather than results. Sylvia. |

So, you're in favor of it, is what you're saying. Predicting long-range technologies accurately is effectively impossible. But the process of doing so rigorously, with enthusiam and ingenuity, leads to progress. People in 1911 who tried to predict what the spaceships of 2011 would look like were not even close to accurate. But in the attempt, they determined that it was *possible.* and so the efforts of a century ago led to the actual spacecraft of half a century ago. Sadly, the politics of half a century ago led to the lack of spaceships today, but that's a different matter. |
