Lethbridge Herald, The (Newspaper) - June 16, 1973, Lethbridge, Alberta THIRD SECTION The LetHbridge Herald Lethbridge, Alberta, Saturday, June 16, 1973 PAGES 29 TO 34 Backing off a bit, a young San Fran- ciscan suddenly has the happy answer scenes of bit native city decorating a, new sculptured fountain. Already a landmark, the fountain Is the work of many artists, all under 14. Un- der the direction of sculptor Ruth Asawa, dozens of schoolchildren cre- ated thousands of bas-relief scenes of San- Francisco. Some can be a bit of a challenge to figure out, but others are as clear as traffic on the Golden Gate Bridge, below.

The "toodstools" are min- iature observatories sitling atop concrete pedestals, spaced approximately miles apart across Manitoba, Saskatchewan and Alberta. Each five-sided station con- tains five wide-angle cameras that scan the night skies for falling burning up as they plunge through the atmosphere. The stations are operated by the National Research Council under a project called Observa- tion and Recovery Project. The project is operated by Dr. Ian Halliday, who says the observatories will be lucky if they photograph a felling meteor "once a year." Distinction This isn't unusual when it is estimated that of the 500 me- teorites that survive to hit earth annually, about 300 land in the sea. Meteorites might land on the Prairies only onea or twice a year. Dr. Halliday said that a dis- tinction has to be made be- tween meteors and mete- orites. A meteor becomes a meteorite only if it survives the passage through the at- mosphere and strikes the earth. "We are quite sure that most of the msteors never drop a meteorite to the he said in an inter- view. The MORP tracking system is only the third of its kind in the world and is featured in an issue of Science Dimen- sion, an NRC publication. While Canada's project has yet to recover a meteorite on the basis of information sup- plied by the MORP stattons, American and Czech- cslovakian operations have photographed many meteors and recovered one meteorite each. "To think of recovery, we have to have at least two tracking stations photograph said Dr. Halliday. By photographing the me- teor's fall, scientists hope to be able to calculate wiUiin a few square miles where ft lands and recover the mete- orite for study. Automatically "To attempt a search of that kind requires quite an ef- fort and the only area you can cover easily is in the said Dr. Halliday, explaining one reason for lo- cating the project in the West. Another is the comparatively clear skies in the region. The project has been in op- eration since the fall of 1971 when the last of the tracking stations was completed. They cost approximately each. They are heated and air-conditioned year round. Every night the station's cameras, operated by pho- tometers, switch on automati- cally. A moving light source in the sky will indicate a probable meteor if it is wunin a certain frequency range and lasts for at least a second. Th3 cameras will reproduce the meteor's trail across the sky as a series of glowing dots. Meteors stop burning at a height of about 12 miles. By then they are travelling through the atmosphere too slowly to burn. A meteorite is seldom hot and never burning when it strikes the ground. May drift The biggest uncertainty in calculating a meteorite's im- pact point is the effect of winds in the atmos- phere that will cause it to drift from the course in- dicated by photographic data. The tracking stations are visited by part-time tech- nicians two or three times a week to check for probelms and reload film when neces- sary. The exposed films are sent to the network's operational headquarters in Saskatoon. Calculations and measure- ments based on the photo- graphs are made there and in Ottawa. Dr. Halliday said recovered meteorites will be sludied for astronomical and other infor- mation on the upper atmos- phere. One area of study will bo the possible effects of cos- mic radiation. Dr. Halliday said samples of any recovered meteorites will probably be turned over the National Meteorite Col- lection maintained by the Ge- ological Survey of Canada in Ottawa.
