Starship Asterisk*

Art - it is the interpreter that completes the work
The distant stars are there to... see, study but not visit...?

I think the most important thing that we've learned from extraterrestrial exploration is that Earth teems with life like no other planet in our solar system. But whether you believe the universe sprang out of nothing, is infinite, or was designed out of nothing, it is difficult… nearly impossible, after looking out into the incredible vastness of the heavens, not to imagine that there is more life elsewhere in the universe. But what if there isn't advanced life outside of Earth? What if we are alone in this awesome and inspiring cosmos? And even if there is life elsewhere, how would we get to it/them if/when we discover evidence? This is a disheartening question for those of us who grew up imagining space travel to distant galaxies and have since been faced with relativity. Travel to even our nearest (and lifeless) stellar neighbor is well beyond a reasonably attainable human journey. Astronomers measure stellar distances in "light years"... how far light travels in one year (time instead of kilometers or miles). The distance light travels in one hour is 1,079,252,848.8 kilometers. So multiply 8,760 hours (a non-leap year) times 1,079,252,848.8 kilometers to find the km distance for one light year... a whopping big number. Sadly, Einstein’s general relativity theory tells us that the universal speed limit for objects with mass (such as spacecraft) is just below the speed of light. And so far, the speed record for space travel is just a meager fraction of that speed. So unless we are somehow able to actually build a much faster spaceship and unless Einstein’s theory is debunked, we are resolved to only dream about traveling even to the closest neighboring star which (currently) happens to be Proxima Centauri at about 4.2 light years distant. But these space travelling dreams so many of us have likely indicate possibility. I believe we look and outreach with hope to the heavens because that is in our nature. I also believe in the design aspect of the universe and it would be disappointing, to say the least, for the Designer not to accommodate this dream someday… how that dream is fulfilled… who can say? Perhaps we will reach the outer stars from a second Earth. Perhaps this second Earth will have new and different physics?? What is apparently impossible in this universe may be possible in another??

life’s flame burns like fusion
propagating emotion like starlit nebulae
who can hide from its beckoning
to the stars… onward outward… ever reaching
for love’s reward

[size=85]The universe is probably littered with the one-planet graves of cultures which made the sensible economic decision that there's no good reason to go into space--each discovered, studied, and remembered by the ones who made the irrational decision.[/size]

There is a more revealing pic at http://en.wikipedia.org/wiki/Cape_Canav ... _Complex_5 - a control panel, almost blank when compared with Mission Control, with a big tape arrow pointing to the firing button. All it lacks is a handwritten sign "Don't press this until really, really ready!"

But that pad has changed completely. What doesn't in 50 years? The rails have gone, the support superstructure has gone and I think the scrub bushes have grown! The blockhouse with that control panel may remain - I haven't been there.

Last night there was a program on TV which also showed this launch and others in the series. I noticed then, as you can see in this picture, that the exhaust is extremely clean and clear compared to recent launches with which I'm familiar. Back then were they using a different mix of propellants on those rockets? Or is it just that they use water now to control the heat transfer to the pad, and the water flashes to steam?

<<On March 11, 2003 Representatives Robert W. Ney (R-Ohio) and Walter B. Jones, Jr. (R-North Carolina) declared that all references to French fries and French toast on the menus of the restaurants and snack bars run by the House of Representatives would be removed. House cafeterias were ordered to rename French fries "freedom fries". This action was carried out without a congressional vote, under the authority of Ney's position as Chairman of the Committee on House Administration, which oversees restaurant operations for the chamber. The simultaneous renaming of French toast to "freedom toast" attracted less attention. According to a statement released by Ney, this move was intended to express displeasure with France's "continued refusal to stand with their U.S. allies". The statement further read: "This action today is a small but symbolic effort to show the strong displeasure many on Capitol Hill have with our so-called ally, France." Reckitt Benckiser, makers of French's mustard, was sufficiently concerned to clarify that their brand name was derived from a family name, and to issue a press release affirming its patriotism.

The Embassy of France in Washington, D.C. made no comment beyond pointing out that French fries come from Belgium. "We are at a very serious moment dealing with very serious issues and we are not focusing on the name you give to potatoes," said Nathalie Loisau, an embassy spokeswoman. Critics also asserted that "French fries" were called such because they are "frenched", or thinly sliced, although this might be a false etymology; the first American reference to French fries was made by Thomas Jefferson, who referred to them as "potatoes, fried in the French Manner".

Congressmen Ney and Jones were not the first to rename French fries "freedom fries"; a number of private restaurants across the country began the renaming movement. Neal Rowland, owner of the privately owned fast-food restaurant Cubbie's in Beaufort, North Carolina began the movement by selling his fried potato strips under the name "freedom fries". Rowland claimed that his intent was not to slight the French people, but rather to be "patriotic and supportive of President George W. Bush" after hearing the news of the French opposition on 19 February 2003. He explained that the name change came to mind after a conversation with a history teacher about World War I, during which anti-German sentiment prompted Americans to rename German foods. Sauerkraut was renamed "liberty cabbage" and hamburgers renamed "liberty steaks" or "Salisbury steaks" (a name that remains in use). The name change is still used by some restaurants, such as Geno's Steaks in Philadelphia and the chain restaurant Toby Keith's I Love This Bar & Grill.>>

Martian 'Freedom 7' Crater [i](Credit: NASA/JPL-Caltech)[/i]

The team exploring Mars via NASA's Opportunity rover for the past seven years has informally named a Martian crater for the Mercury spacecraft that astronaut Alan Shepard christened Freedom 7. On May 5, 1961, Shepard piloted Freedom 7 in America's first human spaceflight.

The team is using Opportunity this week to acquire images covering a cluster of small, relatively young craters along the rover's route toward a long-term destination. The cluster's largest crater, spanning about 25 meters (82 feet), is the one called "Freedom 7." The diameter of Freedom 7 crater, about 25 meters (82 feet), happens to be equivalent to the height of the Redstone rocket that launched Shepard's flight.
...
By taking advantage of seeing many craters of diverse ages during drives toward major destinations, the Opportunity mission is documenting how impact craters change with time. The cluster that includes Freedom 7 crater formed after sand ripples in the area last migrated, which is estimated to be about 200,000 years ago.
