Mountain Views-News Saturday, August 26, 2017 11THE WORLD AROUND US IN QUEST TO REACH ALPHA CENTAURI, BREAKTHROUGH STARSHOT LAUNCHES WORLD’S SMALLEST SPACECRAFT Mountain Views-News Saturday, August 26, 2017 11THE WORLD AROUND US IN QUEST TO REACH ALPHA CENTAURI, BREAKTHROUGH STARSHOT LAUNCHES WORLD’S SMALLEST SPACECRAFT Breakthrough Starshot, a multi-facetedprogram to develop and launch practicalinterstellar space missions, successfullyflew its first spacecraft—the smallest everlaunched. On June 23, a number of prototype“Sprites”—the world’s smallest fullyfunctional space probes, built on a singlecircuit board—achieved low Earth orbit, piggybacking on OHB System AG’s ‘Max Valier’ and ‘Venta’ satellites. The 3.5-by-3.5centimeter chips weigh just four grams butcontain solar panels, computers, sensors, and radios. These vehicles are the next stepof a revolution in spacecraft miniaturizationthat can contribute to the development ofcentimeter- and gram-scale “StarChips” envisioned by the Breakthrough Starshotproject. The Sprite is the brainchild of BreakthroughStarshot’s Zac Manchester, whose 2011 Kickstarter campaign, “KickSat,” raisedthe first funds to develop the concept. TheSprites were constructed by researchers atCornell University and transported intospace as secondary payloads by the MaxValier and Venta satellites, the latter built bythe Bremen-based OHB System AG, whosegenerous assistance made the missionpossible. The Sprites remain attached to thesatellites. Communications received from the mission show the Sprite systemperforming as designed. The spacecraftare in radio communication with groundstations in California and New York, as well as with amateur radio enthusiasts around the world. This mission is designed to testhow well the Sprites’ electronics perform inorbit, and demonstrates their novel radio communication architecture. Breakthrough Initiatives—includingmost notably, Breakthrough Starshot andBreakthrough Listen—are a set of longterm astronomical programs exploringthe universe, seeking scientific evidence oflife beyond Earth, and encouraging public debate from a planetary perspective. Breakthrough Starshot, announced on April 12, 2016, by Yuri Milner andStephen Hawking, is a $100 million research and engineering program aimingto demonstrate proof of concept for light- propelled spacecraft that could fly at 20percent of light speed and, in just over 20years after their launch, capture imagesand other measurements of the exoplanetProxima b and other planets in our neareststar system, Alpha Centauri. The Starshot concept envisions launchinga “mothership” carrying about a thousandtiny spacecraft (on the scale of centimeters) to a high-altitude orbit and then deployingthem. A phased array of ground-basedlasers would then focus a light beam on thecrafts’ solar sails to accelerate them one byone to the target speed within 10 minutes, with an average acceleration on the orderof 100 km/s2, and an illumination energyon the order of 1 TJ delivered to each sail, estimated to have a surface area of 4 m . 4 m. If an Earth-size planet is orbiting withinthe Alpha Centauri system habitable zones, Breakthrough Starshot will try to aim itsspacecraft within 1 astronomical unit (93million miles) of it. From this distance, acraft’s cameras could potentially capturean image of high enough quality to resolvesurface features. The fleet would have about 1000 spacecraft, and each one would be a verysmall centimeter-sized vehicle weighing afew grams. They would be propelled by asquare-kilometer array of 10 kW ground- based lasers with a combined output of upto 100 GW. Each spacecraft would transmitdata back to Earth using a compact on- board laser communications systemusing its solar sail as an antenna and thepropulsion array as the receiver.

CHRISTOPHER Nyerges A TALK AT THE ROTARY CLUB [Nyerges is the author of many books including “Extreme Simplicity: Homesteading in the City” and “How to Survive Anywhere.” He also leads outdoor expeditions. For more information, he can be reached at www.SchoolofSelf-Reliance.com, or Box 41834, Eagle Rock, CA 90041]. Last Tuesday, I gave an early-morning lectureto the Sierra Madre Rotary club, one of the city’sservice organization. Just to get to the meetingrequired hardiness and orienteering skills, sinceI had to arrive at 7 a.m. (that’s way earlier than I usually get up) and then I had to search for anearly-hidden small room in Sierra Madre Park. But I found the place, and was greeted by the friendlymembers, including the excellent chef Mario whocreated a top-notch omelette for me as I watched andgave directions. I was thinking, the omelette alone is agood reason to be a Rotarian. My presentation revolved around the topics that Ihave been teaching all my life – ethnobotany, native usesof plants, and some of the ways that past civilizationsutilized the natural flora to provide not only food, butmedicine, fire, even clothing and cordage. I brought many of the seasonal wild plants to showthe assembled members, such as native wild cherries which were in season. These are thin-fleshed fruit which are tasty, though the leaves are toxic. We also saw some of the most nutritious plants inthe world, according to the USDA: lambs quarter, curlydock, and dandelion. These are all despised by farmersbecause they are invasive weeds, but each is highlynutritious. Lambs quarter – a relative of the popularquinoa – has edible leaves and seeds and eating it islike taking a mineral tablet. Curly dock is the highestsource of vitamin A, and dandelion is the highest sourceof beta-carotene. The members also got to see the remarkable yuccaleaves, and see sandals, rope, and brushes that weremade from this desert plant. I also shared some of my thoughts about some of thepast civilizations of North America, such as the Cahokia(they had the largest pyramid north of Mexico City, inpresent day Illinois), the Adena, and the Anasazi. I shared some ideas about what caused the demise of the vast Anasazi empire, and wondered if our civilizationcould one day suffer a similar fate. In fact, recognizingthe non-sustainability of many of the our current socialpractices is why I got interested in ethno-botany andsurvival in the first place. Through osmosis, I also learned a lot about theRotary Club by being there. For one, they are greatfund-raisers for the club, and a can was constantlybeing passed around with many dollar bills going intoit. I also learned that Rotarians will drop everything ata moment’s notice and help people in need, even peoplein a distant country. At the meeting, they all pledged allegiance to the flag, they sang songs, and they eagerly shared some of theirpersonal business enterprises. Oh, and did I mention Mario who makes an incredible omelette? At the end of the meeting, they all recited the Rotarian Code foranalysis of activities and events: Is it the truth? Is it fair to all concerned? Will it build goodwill and betterfriendship? Will it be beneficial to all concerned? What a great code! It’s too bad that everyone doesn’t live bythe Code of the Rotary Club. I realized as I left and walked over the Bean Town for another cup of coffee, that Sierra Madre is a really greattown. I got to see some of my favorite people on mywalk. Steve Hardy, Sierra Madre’s resident artist, greetedme as he looked up from another art work. And ChrisLeclerc, Sierra Madre’s famous dog walker and caninecolumnist, let me pet her beautiful little puppy she waswalking. Sierra Madre is a great town, and everyone can feelgood to be a part of it. Get to know your neighbors andvolunteer in activities that help the community. OUT TO PASTOR A Weekly Religion Column by Rev. James Snyder CELEBRATION HAS BECOME A WAY OF LIFE FOR ME I have just celebrated my birthday, my wife’s birthday and our wedding anniversary. I am not sure how old I am or how long we have been married and I won’t even go to my wife’s age. I’m old enough to know better. I have long past the idea of candles on my birthday cake representing one candle per year. The fire department will not give us a permit to do that. Someone asked me how long we have been married and without even thinking, I said, “Forever.” Once that word danced out of my lips I knew I was in trouble with the Gracious Mistress of the Parsonage. One look from her, and I knew that my forever had ended. All seriousness aside, celebrations are wonderful opportunities, at least from my point of view, to gorge myself with cake. After all, if it is my birthday or anniversary or my wife’s birthday, I should be respectful enough to eat the cake presented. At my age, I’m not too concerned about eating healthy. That’s why I love the holidays. Between holidays, my wife insists on eating healthy. I cannot even name all of the vegetables that appear on our table at suppertime. I think they are vegetables, my wife says they are vegetables, but I am not so sure about it. My wife believes that if it is green and leafy it must be a vegetable. I, on the other hand, with a fork in each hand, have had enough vegetables I want to get to the celebratory cake. After all, what is the sense in celebrating a birthday or an anniversary if you cannot eat the cake presented? Especially if it is my birthday. I will give my wife the latitude to put vegetables, so-called, on our dinner table between our celebrations. The problem is, my birthday, her birthday and our anniversary are within three weeks of each other. That means, there are 49 weeks that I have to put up with vegetables. Therefore, I am a great one when it comes to celebrating something. Anything. I am so glad that our culture is assisting me in this. It has come to the point where there is a celebration for every day of the year. I do not care what I’m celebrating, as long as cake is involved, I’m right there. After all, I certainly don’t want to offend anybody. In my carefulness to not offend anybody in this regard, I have on occasion offended my wife. She is a vegetableaholic if ever there was one. She even eats vegetables as a snack. Once at a church fellowship, she brought in a huge plate of raw vegetables, insinuating it was a snack tray. Recently, I was sitting in my lazy-boy chair, drinking a nice hot cup of coffee and reflecting on the important issues of life. I cannot tell you how many problems in this world I have solved if only somebody would listen to me. However, in my muse a wonderful thought embraced several grey cells. What if, and I don’t have any legitimate documentation on this, when we get to heaven, it is a celebration every day with cake only an angel could bake? And what if, every day it was somebody’s birthday and we needed to celebrate it? That certainly would make heaven for me. Further, in my muse, what if there were no vegetables whatsoever to be found at the Marriage Supper of the Lamb? That too would make heaven, heaven for me. What if all we had at that table was cake, pie, ice cream and soda pop? Wouldn’t that just be divine? I think most people, particularly my wife, take this matter of eating healthy too seriously. I think when a person eats it should be an enjoyable experience and not a ragged old duty. I wonder what kind of soda pop they will have in heaven? I’m sure it will not be a diet soda. Why would we be dieting in heaven? What if, and again, I am speculating, everyone in heaven is fat? Everyone is fat, eating, laughing and enjoying themselves. Wouldn’t that be a shock to some people? I’m not saying it is, but who’s to say it isn’t? A person can dream, can’t they? That certainly would be something worth celebrating. In the midst of all this musing, my wife happened to walk in and said, “What in the world are you smiling at?” I confess it caught me a little off guard. I looked at her, still smiling and said, “I was thinking about heaven and the great time we are going to have celebrating up there.” I did not give her any particulars, because it was my dream. All she said was, “I think it’ll be a wonderful time up there celebrating.” Her idea of celebrating may not be exactly my idea of celebrating, but then why get caught up in particulars. Her celebration may be different from my celebration, but if both of us are happy in that celebrating atmosphere, what’s the harm? I couldn’t help but think of what Jesus once said to his disciples. “I am the living bread which came down from heaven: if any man eat of this bread, he shall live for ever: and the bread that I will give is my flesh, which I will give for the life of the world” (John 6:51). The best celebration that I know of is feasting upon that “living bread” which is none other than Jesus Christ. Dr. James L.
