Less Ageism, Please The January 4 issue of this publication proved to me that there are some sensible voices of reason in our community regarding all things “inter-generational.” I offer a word of thanks to Elizabeth Myers. I too have worked hard for what I’ve earned throughout my years in the various positions I’ve held. While I too cannot speak for each millennial, brash generalizations about a lack of work ethic don’t sit well with me...Joe Connolly, Traverse City

Now That’s an Escalation I just read the letter from Greg and his defense of the AR15. The letter started with great information but then out of nowhere his opinion went off the rails. “The government wants total gun control and then confiscation; then the elimination of all Constitutional rights.” Wait... what?! To quote the great Ron Burgundy, “Well, that escalated quickly!”

Healthy Eating and Exercise for Children Healthy foods and exercise are important for children of all ages. It is important for children because it empowers them to do their best at school and be able to do their homework and study...

Mascots and Harsh Native American Truths The letter from the Choctaw lady deserves an answer. I have had a gutful of the whining about the fate of the American Indian. The American Indians were the losers in an imperial expansion; as such, they have, overall, fared much better than a lot of such losers throughout history. Everything the lady complains about in the way of what was done by the nasty, evil Whites was being done by Indians to other Indians long before Europeans arrived...

Snyder Must Go I believe it’s time. It’s time for Governor Snyder to go. The FBI, U.S. Postal Inspection Service and the EPA Criminal Investigation Division are now investigating the Flint water crisis that poisoned thousands of people. Governor Snyder signed the legislation that established the Emergency Manager law. Since its inception it has proven to be a dismal failure...

Erosion of Public Trust Let’s look at how we’ve been experiencing global warming. Between 1979 and 2013, increases in temperature and wind speeds along with more rain-free days have combined to stretch fire seasons worldwide by 20 percent. In the U.S., the fire seasons are 78 days longer than in the 1970s...

Star Sailor

Harley Sachs - July 7th, 2005
There’s a whirligig gadget on my window sill that may have come from a science museum, for it illustrates a power of light that is now being applied to space flight. It resembles a clear glass light bulb, but instead of a filament inside there’s a little windmill -- four black and white paddles that rotate on needle mounted in a pillar of glass. When sunlight strikes the paddles the gadget turns and in bright sunlight it spins. As long as the sun shines on it, it keeps on spinning.
The principle is simple: the pressure of the beams of light striking the blades causes the gadget to spin. This wouldn’t work if the blades were not sealed in a vacuum, for the pressure of the light is not strong enough to turn the blades in the presence of resistant air. This might seem like a perpetual motion machine, were it not for two factors. Eventually the pivot point where the blades rest on the column will wear out. So far, after many years on my window sill, that hasn’t happened. What has prevented this device from running forever is that the glass is not totally impermeable. Atom by atom, air has penetrated the glass so it is not a perfect vacuum and it takes more and more intense sunlight to make it turn.
But what if the same principle were applied to a sail on a space ship? Then, like the marvelous prairie schooner of Pecos Bill sailing across the sea of grass of our Great Plains, a space ship would go on in the vacuum of space, accelerating forever.

ULTRA-THIN SAILS
That was precisely the intention of a new space experiment launched from the Russian nuclear submarine Borisoglebsk. A Volne intercontinental ballistic missile was modified to carry the sailing space vehicle, Cosmos-1 and launched on what was planned to be a 500 mile high orbit. That was a nice peaceful modification for an otherwise lethal ICBM.
According to the website for the California-based Planetary Society, which sponsored the craft, signals were recorded independently at three ground stations, at Petropavlovsk in Kamchatka, Majuro in the Marshall Islands and Panska Ves in the Czech Republic, that Cosmos-1 was expected to pass over.
The society web page describes the Cosmos 1 as having eight triangular sails, each 50 feet long with the spacecraft’s body at the center. If the launch was successful, once reaching orbit the space craft would open the ultra-thin sails to be driven by the power of impacting photons from the sun, just like my window sill gadget.
This is seen as a solution for space flight, for such a space ship doesn’t need to carry fuel for propulsion. Like my 22-foot-sloop which sails Lake Superior on free wind, the Cosmos-1 would sail through space propelled by the pressure of a kind of solar wind.

MISSING
Unfortunately, although it was sponsored by Planetary Society enthusiasts from around the world, the Cosmos-1 has gone missing.. Apparently one engine of the Volne missile failed and the Cosmos-1 disappeared.
This doesn’t mean that the adventure is over. If you visit their web site you’ll discover that the Society sells T shirts, Cosmos-1 souvenirs, and posts a great deal of information about space flight going back to the days of Jules Verne and other science fiction imagineers for whom the Cosmos-1 is a present reality.
Now when I look at that little spinning solar windmill on my window sill, I will think of the Cosmos-1 and adventures of future sailors in space.
