Para mi hermano del alma / For my soul brother Juli Modul (Juli Morató Torres).


"Cuando nuestro mundo alcanzó la mitad de su edad actual, algo que venía de las estrellas pasó a través del Sistema Solar, dejó aquella huella de su paso, y prosiguió su camino. Hasta que nosotros la destruimos, aquella máquina cumplió su cometido. Y empiezo a intuir cuál era.

Alrededor de cien mil millones de estrellas giran en el círculo de la Vía Láctea, y, hace mucho tiempo, otras razas de los mundos pertenecientes a otros soles deben de haber alcanzado y superado el estadio en el que ahora nos hallamos nosotros. Piensen en una tal civilización, muy lejana en el tiempo, cuando la Creación era aún tibia, dueña de un universo tan joven que la vida había surgido tan sólo en una infinitésima parte de mundos. La soledad de aquel mundo es algo imposible de imaginar, la soledad de los dioses que miran a través del infinito y no hallan a nadie con quien compartir sus pensamientos.

Deben de haber explorado las galaxias como nosotros exploramos los mundos. Por todos lados había mundos, pero estaban vacíos, o a lo sumo poblados de cosas que se arrastraban y eran incapaces de pensar. Así debía de ser nuestra Tierra, con el humo de los volcanes ofuscando aún el cielo, cuando la primera nave de los pueblos del alba surgió de los abismos más allá de Plutón. Rebasó los planetas exteriores apresados por el hielo, sabiendo que la vida no podía formar parte de sus destinos. Alcanzó y se detuvo en los planetas interiores, que se calentaban al fuego del Sol, esperando a que comenzara su historia.

Aquellos exploradores deben de haber observado la Tierra, sobrevolando la estrecha franja entre los hielos y el fuego, llegando a la conclusión de que aquél debía de ser el hijo predilecto del Sol. Allí, en un remoto futuro, surgiría la inteligencia; pero ante ellos quedaban aún innumerables estrellas, y nunca regresarían por aquel mismo camino.

Así pues, dejaron un centinela, uno de los millones que deben de existir esparcidos por todo el universo, vigilando los mundos en los cuales vibra la promesa de la vida. Era un faro que, a través de todas las edades, señalaba pacientemente que aún nadie lo había descubierto.

Quizás ahora comprendan por qué la pirámide de cristal fue instalada en la Luna y no en la Tierra. A sus creadores no les importaban las razas que luchaban aún por salir del salvajismo. Nuestra civilización les podía interesar tan sólo si dábamos prueba de nuestra capacidad de supervivencia, lanzándonos al espacio y escapando así de la Tierra, nuestra cuna. Este es el desafío que, antes o después, se plantea a todas las razas inteligentes. Es un desafío doble, porque depende de la conquista de la energía atómica y de la decisiva elección entre la vida y la muerte.

Una vez superado este punto crítico, era tan sólo cuestión de tiempo que descubriéramos la pirámide, y la forzásemos para ver lo que había dentro. Ahora ya no emite ninguna señal, y aquellos encargados de su escucha deben de haber vuelto su atención hacia la Tierra. Quizás acudan a ayudar a nuestra civilización, aún en su infancia. Pero deben de ser viejos, muy viejos, y a menudo los viejos son morbosamente celosos de los jóvenes.

Ahora ya no puedo mirar la Vía Láctea sin preguntarme de cuál de esas nebulosas estelares están acudiendo los emisarios. Si me permiten hacer una comparación bastante vulgar, hemos tirado del aparato de alarma, y ahora no podemos hacer otra cosa más que esperar.

No creo que tengamos que esperar mucho."

Fragmento del cuento "El Centinela", Arthur C. Clarke, 1957

"When our world was half its present age, something from the stars swept through the Solar System, left this token of its passage, and went again upon its way. Until we destroyed it, that machine was still fulfilling the purpose of its builders; and as to that purpose, here is my guess.

Nearly a hundred thousand million stars are turning in the circle of the Milky Way, and long ago other races on the worlds of other suns must have scaled and passed the heights that we have reached. Think of such civilizations, far back in time against the fading afterglow of Creation, masters of a universe so young that life as yet had come only to a handful of worlds. Theirs would have been a loneliness we cannot imagine, the loneliness of gods looking out across infinity and finding none to share their thoughts.

They must have searched the star-clusters as we have searched the planets. Everywhere there would be worlds, but they would be empty or peopled with crawling, mindless things. Such was our own Earth, the smoke of the great volcanoes still staining the skies, when that first ship of the peoples of the dawn came sliding in from the abyss beyond Pluto. It passed the frozen outer worlds, knowing that life could play no part in their destinies. It came to rest among the inner planets, warming
themselves around the fire of the Sun and waiting for their stories to begin.

Those wanderers must have looked on Earth, circling safely in the narrow zone between fire and ice, and must have guessed that it was the favorite of the Sun’s children. Here, in the distant future, would be intelligence; but there were countless stars before -them still, and they might never come this way again.

So they left a sentinel, one of millions they have scattered throughout the Universe, watching over all worlds with the promise of life. It was a beacon that down the ages has been patiently signaling the fact that no one had discovered it.

Perhaps you understand now why that crystal pyramid was set upon the Moon instead of on the Earth. Its builders were not concerned with races still struggling up from savagery. They would be interested in our civilization only if we proved our fitness to survive -by crossing space and so escaping from the Earth, our cradle. That is the challenge that all intelligent races must meet, sooner or later. It is a double challenge, for it depends in turn upon the conquest of atomic energy and the last choice between life and death.

Once we had passed that crisis, it was only a matter of time before we found the pyramid and forced it open. Now its signals have ceased, and those whose duty it is will be turning their minds upon Earth. Perhaps they wish to help our infant civilization. But they must be very, very old, and the old are often insanely jealous of the young.

I can never look now at the Milky Way without wondering from which of those banked clouds of stars the emissaries are coming. If you will pardon so commonplace a simile, we have set off the fire-alarm and have nothing to do but to wait.

I do not think we will have to wait for long."

Tom and the rest of the "rocket pit crew" helped me get it on the rail. (photo by oddwick)

It’s my heaviest rocket project so far. I fiber-glassed the body, added a flight computer up in the nose cone, epoxy-coated the fins, and filled the remaining free space in the nose and tail cones with expanding two-part foam.

I like the sleek shape and symmetry of the design. In the early days of rocketry, I wonder if the comic books were the design inspiration. It turns out that this shape and weight distribution is unstable, and so I epoxied two pounds of lead buck shot into the tip of the nose cone to keep it from spiraling out of control.

Here I am adjusting the angle to tilt slightly into the wind (to reduce the recovery hike distance).

I have already armed the on-board computer which will detonate 5 grams of black powder to pop a large parachute when it detects apogee (it has barometric and tilt sensors and an accelerometer; it also logs flight data for later PC download). The motor also has an ejection charge that will detonate 14 seconds after launch as a redundant precaution.

The last step will be to thread the electric igniter up through the center of the solid-AP Aerotech K550 motor. After clipping to the 12V power supply and a continuity test, she is ready to fly.

We are go flight.

Walking the Dogs (Explored)

In Far North Bicentennial Park outside Anchorage, Alaska, there is a no-leash area for dogs. This is not simply a "city dog park," this is a huge tract of wilderness where there are no leash requirements.

This wise policy really helps with the multi-user problems we have recreating in the out of doors in Alaska around Anchorage. (Not much of a problem anywhere else in Alaska!). In the Winter, people flock to the outdoors to Ski, Snow Machine China, Cross-Country Ski, Skijoring (where one or two dogs pull you on your skis), Ice Skating and Ice Fishing on frozen lakes, serious Dog Sledding with huge dog teams coming down the trail, winter Bicyclists, Hikers, Dog Walkers, and Nature and Wildlife Photographers!

This is pretty much what people do here in the Winter in the snow and ice in Parks. I’m leaving out people who climb up the face of frozen waterfalls because I think they are nuts! 🙂

But many of these outdoor activities conflict with dogs running free on the trails and in the Parks. Therefore, we have leash laws. Mostly ignored and seldom enforced, it basically turns out to be an exercise in good judgement on the dog owner’s part. Like when you hear a musher yelling at his or her team at the top of their lungs (BTW, there are a lot of women mushers in Alaska!) and the sound of 12 loudly barking dogs coming from around the corner ahead of you, it’s best to get your dog under control and off the trail as soon as possible…!!!!

Well, this wonderful, large, pristine wilderness that’s dedicated to dogs being off leash is really a safe haven for dogs and makes being out with them off-lead far more relaxed. Especially in the Winter when there are no bears around.

In the non-Winter times, there is an obvious risk to letting your dog run free in the Wilderness. About three Summers ago in this area, we came upon a huge Grizzly Bear eating a Moose kill and it took us about one nanosecond to offer him our congratulations on his fine meal, and quietly disappear backwards! 🙂

Happy New Year!
