Sky's Up July - September 2018 | Page 48

Mars has long been a source of fascination David Levy at the Jewish National Home for Asthmatic Children in Septem ber 1962. on the road with Doveed By DAVID H. LEVY Sky’s Up Editor in Chief Mars and I have been friends since February 2, 1963. On that evening I was a 14-year-old patient at the Jewish National Home for Asthmatic Children. I didn’t know much about anything, but I did want to take a look at Mars. And I did understand that at 8:02 p.m. Mountain time, Mars would be in direct opposition in the night sky, meaning that it would be in the sky from dusk to dawn. I assumed that Mars would put on quite a show. Carefully checking my watch, I began looking at this red planet just before 8. I thought that promptly at 8:02, Mars would puff up in a burst of cosmic radiance. I thought it would briefly become so bright that I’d have to shield my eyes. That never happened. Mars just stayed as it was. I might have spotted a darker area at the top, now understood to be one of the polar caps. But essentially Mars just sat there, staring at me as I stared at it. After a while I brought Echo, my telescope, inside our cottage where Jim, my houseparent, was waiting. “You were standing behind the girls’ cottage with a telescope,” he said accusingly. “What were you doing?” “Looking at Mars,” I answered innocently. Jim looked at me, then his face broke out in peals of laughter. “You are the only person who could say that and get away with it!” And that is how I became friendly with Mars. Mars at noon: No canals My second encounter with Mars took place during the Summer of 1965. Now 17, I was a camper at the Adirondack Science Camp in upstate New York. I saw the banner headline in the New York Times that day. Humanity had just sent its first spacecraft flying past Mars. Called Mariner 4, the craft was designed to fly past the planet and take closeup pictures. One 48 specific area it was photographing was a spot where, decades earlier, Percival Lowell had reported seeing artificial canals there. Would Mariner confirm both the canals and the existence of intelligent life on Mars? Mariner did neither. It spotted what appeared to be a bright surface pockmarked with craters, but nothing else, and certainly no canals. For those of us who wanted so badly not to be alone, this was a disappointment, but, as years passed, the question of life on Mars would not go away. Intelligent life, canal-building life? Probably not. But what about simpler forms of sub-microbial life? A fossil from Mars? Several thousand years ago a bright meteorite broke up in Earth’s atmosphere and crashed in the Allan Hills region of Antarctica. In 1983, a team discovered and collected that rock, and it has since been confirmed that the specimen did indeed come from Mars. In 1995, David McKay and his group of planetary scientists suggested that the rock displayed possible evidence of fossilized life. Despite a huge amount of excitement at the time, it now appears not likely that this was a fossil. But the questions linger. At the time, McKay, the team leader, suggested that it is possible that microscopic life forms persist to this day. Did the scientists have egg on their faces? Not at all. Their discovery inspired an intense search for life on other worlds, not just Mars, but ice-covered Europa, a large moon of Jupiter, as well. The rock did not answer any questions, but it did pose some brilliant ones. Someone, perhaps someone reading these pages of Sky’s Up, might be the one who comes up with the answers, and, at the same time, poses even more questions. Sky ’ s Up
