    "content": "The news article below, leads to a question about the current Eagle project\nas well as future AMSAT-NA projects.\n\nAll metric measurement based?\n\nGreg. w9gb\n\n===================================\nNASA boldly goes with Metric System (SI)\nhttp://www.canada.com/montrealgazette/news/story.html?id=eca86baf-b80e-4941-9bea-a2711e9c0bce&k=82801\n\n\nTOM SPEARS, CanWest News Service\nPublished: Friday, January 12, 2007\n\nNASA has finally agreed to fly to the moon in metric - a move its\nscientists have wanted ever since they mixed up kilometres with miles\nand crashed an expensive spacecraft near Mars.\n\nSpace is an international business. And NASA says that only scientists\nof the United States, Myanmar and Liberia still measure distance in\nmiles.\n\nNASA's Vision for Space Exploration calls for returning astronauts to\nthe moon by 2020 and eventually setting up a manned lunar outpost.\n\nThis week, the agency announced it will make the lunar project a\nmetric-only job.\n\nNASA quotes a senior moon mission manager, Jeff Volosin, as saying: \"I\nthink NASA has been seen as maybe a bit stubborn by other space\nagencies in the past, so this was important as a gesture of our\nwillingness to be co-operative when it comes to the moon.\"\n\nThe change, announced after talks with space agencies from Canada and\n14 other nations, could leave any space experts in Myanmar and Liberia\non their own. Canada, however, seems pleased.\n\n\"Space engineering is tough enough without continuously having to\nremember all the conversion factors between various units,\" said Ben\nQuine, a professor of space engineering at York University.\n\n\"So it's good news that they're joining us, and good news for\ninternational collaboration.\n\n\"All of our courses are taught in SI (metric measure, abbreviated from\nthe French Systeme international) so it will make it easier for our\ngraduates to get jobs south of the border.\"\n\nA probe called Mars Climate Orbiter reached Mars in 1999, but entered\nfar too low in orbit and crashed on its first loop around the planet's\nfar side. NASA later said its engineers had messed up a conversion of\norbital information from metric to imperial units.\n\nNASA started using metric measurements in some operations in 1990, but\nmuch of its work - such as aspects of shuttle missions and the\nInternational Space Station - continues in miles, pounds and gallons.\n\n\"My favorite imperial unit is the slug. The launch force of the\nshuttle is measured in slugs,\" Quine said. (The slug is defined as the\nmass that receives an acceleration of one foot per second per second\nwhen a force of one pound is applied to it.)\n\nMaking the change won't be easy for the Americans, he noted.\n\n\"Everybody has to be careful with their units when they convert.\" But\nhe says it will make calculations easier in the long run. Everything\nfits together by tens, hundreds and so on.\n\n\"The foot was based on the size of the foot of one of the kings of\nEngland. I can't remember which one it is now. That's no way to run a\nspace program, based on the size of a dead king's foot.\"\n",
