Alan Blackwell of Saskatoon, director of the National Research = Council's meteorite observation and recovery project, said the meteorite = which fell to earth Feb. 5 in a field near the community 90 east of = Edmonton is thought to have come from beyond the planet Saturn. Mr. Blackwell said only three meteorite in history have been = recovered shortly after their fall has been recorded by time-lape = photographs which enables precise calculations of their orbits. The two = previous meteorites did not come from as far, he said. Mr. Blackwell said calculations based on the trajectory recorded by = the project's cameras indicate the meteorite came from much further out = in space than meteorites were previously though to exist - beyond = Saturn, a billion miles from the sun. "The connection between this meteorite and a comet will be a matter = for a lot of speculation, I think." Mr. Blackwell said. "It used to be thought that meteorites did not have the same kind = of orbits as comets. Only comets were thought to have orbits going out = that far and coming this close." He said hundreds of meteorites are sighted each year by a network = of 12 camera stations located across teh agricultural region of the = prairies. The prairies are considered a good place to maintain a camera to = watch for meteorites because of their relatively clear skies and the = accessibility to almost any point a meteorite might land. However, most of them burn up and in a few cases when one was = thought to have hit the ground, a search of the area revealed nothing. "We are fortunate to occasionally get these free samples from = space," he said, adding that research on the meteorites will tell = scientists about the cosmic ray environment of outer space, since it was = recovered quickly enough the effects have not worn off. It will also hold clues about what was around when the solar system = was made, he said. The Innisfree meteorite, which weighs four pounds, seven ounces, = now is at the Batalle Institute in the state of Washington. "We rushed it there within a day of finding it becasue the = radioactivity in it is short-lived and that is the only place in North = America capable of making the appropriate tests." After several weeks at the Batelle Institute, the meteorite will be = send to the University of Alberta for geological study and part of it = will go to the national meteorite collection in Ottawa, he said. Mr. Blackwell said the project's computers which calculated the = probable point of impact from photographs taken at stations at = Vegreville, Alta., and Lousana, Alta., were accurate to within 1/4-mile. = Vegreville is located about 60 miles east of Edmonton while Lousana is = about 30 miles southeast of Red Deer. Photo shows a man in a winter jacket standing in snow: Ian Halliday, a = strophysicist with the National Research Council, hold a piece of a = meteorite found on a farm near Innisfree, Alta. about 90 miles east of = Edmonton. The meteorite had been photographed falling across Alberta's = skies earlier this month. Mark Note: Named the Innisfree Meteorite, this stone was classified as = a L5 Stone Chondrite. The meteorite fell Febuary 5, 1977 at 7:17am = local time. 9 pieces in total were recovered totalling 4.58kg. ------=_NextPart_000_0003_01C30739.42B20880 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=3DContent-Type = content=3Dtext/html;charset=3Diso-8859-1> <META content=3D"MSHTML 6.00.2800.1141" name=3DGENERATOR> <STYLE></STYLE> </HEAD> <BODY id=3DMailContainerBody=20 style=3D"PADDING-LEFT: 10px; FONT-WEIGHT: normal; FONT-SIZE: 10pt; = COLOR: #000000; BORDER-TOP-STYLE: none; PADDING-TOP: 15px; FONT-STYLE: = normal; FONT-FAMILY: Verdana; BORDER-RIGHT-STYLE: none; = BORDER-LEFT-STYLE: none; TEXT-DECORATION: none; BORDER-BOTTOM-STYLE: = none"=20 leftMargin=3D0 topMargin=3D0 acc_role=3D"text" CanvasTabStop=3D"true"=20 name=3D"Compose message area"><?xml:namespace prefix=3D"v" = /><?xml:namespace prefix=3D"o" /> <DIV>Title: Lethbridge Herald <BR>City: Lethbridge, Alberta <BR>Date: = Wednesday,=20 February 23, 1977<BR>Page: 21</DIV> <DIV> </DIV> <DIV>'Meteorite, comet link may be = reassessed'<BR> =20 SAKATOON (CP) - The photographing and recovery of a meteorite near = Innusfree,=20 Alta., earlier this month may lead scientists to reasses the connection = between=20 comets and meteorites, a scientist says.<BR> = Alan=20 Blackwell of Saskatoon, director of the National Research Council's = meteorite=20 observation and recovery project, said the meteorite which fell to earth = Feb. 5=20 in a field near the community 90 east of Edmonton is thought to have = come from=20 beyond the planet Saturn.<BR> Mr. Blackwell said = only=20 three meteorite in history have been recovered shortly after their fall = has been=20 recorded by time-lape photographs which enables precise calculations of = their=20 orbits.
