Opportunity cost - Wikipedia, the free encyclopedia Opportunity cost is a term used in economics to mean the cost of something in terms of an opportunity forgone (and the benefits that could be received from that opportunity), or the most valuable forgone alternative. In building the hospital, the city has forgone the opportunity to build a sporting center on that land, or a parking lot, or the ability to sell the land to reduce the city's debt, and so on. Opportunity cost need not be assessed in monetary terms, but rather can be assessed in terms of anything that is of value to the person or persons doing the assessing. en.wikipedia.org /wiki/Opportunity_cost   (1071 words)

Opportunity rover - Wikipedia, the free encyclopedia Opportunity (official designation: MER-B) is the second of the two rovers of NASA's Mars Exploration Rover Mission.

Spaceflight Now | Destination Mars | Mission Status Center Opportunity awoke on sol 102 from its first "deep sleep." This set of activities was initiated to conserve the energy that is being used by the instrument arm's stuck-on heater switch. Opportunity sits about half a meter (1.6 feet) outside the edge of the crater with a positive pitch of 4.7 degrees, meaning the rover is slightly tilted with its head up. Opportunity is currently parked near the trench it dug on its 73rd martain sol. spaceflightnow.com /mars/mera/status.html   (8988 words)

Mars Exploration Rover Mission: Panoramas: Opportunity The panoramic camera aboard NASA's Mars Exploration Rover Opportunity acquired this panorama of the "Payson" outcrop on the western edge of "Erebus" Crater during Opportunity's sol 744 (Feb. 26, 2006). This is the left-eye member of a stereo pair showing the landscape surrounding NASA's Mars Exploration Rover Opportunity at the edge of "Erebus Crater" while the rover's panoramic camera captured frames for a full-circle panorama on Opportunity's sols 652 to 663 (Nov. 23 to Dec. 5, 2005). This is the Opportunity panoramic camera's "Erebus Rim" panorama, acquired on sols 652 to 663 (Nov. 23 to Dec. 5, 2005), as NASA's Mars Exploration Rover Opportunity was exploring sand dunes and outcrop rocks in Meridiani Planum. origin.mars5.jpl.nasa.gov /gallery/panoramas/opportunity   (1305 words)

NASA frees rover from Martian sand trap - Return to the Red Planet - MSNBC.com   (Site not responding. Last check: 2007-10-21) The Opportunity rover and Spirit, its twin on the other side of Mars, have been studying the Red Planet from the surface since January 2004. Last year Opportunity sent back headline-grabbing evidence that its landing site was drenched with water in ancient times, and in recent weeks Spirit has been sending back findings that point to a violent geological past as well as the presence of water in ancient times. Opportunity broke free after making about 3 feet (93 centimeters) of inch-by-inch progress — a sudden breakthrough that was in line with what happened in the Pasadena sandbox. msnbc.msn.com /id/8098155   (712 words)

New Scientist Breaking News - Mystery of Mars rover's 'carwash' rolls on NASA's Mars rover Opportunity seems to have stumbled into something akin to a carwash that has left its solar panels much cleaner than those of its twin rover, Spirit. Opportunity's output also declined at first - to around 500 watt-hours - but over the past six months it has regained power (New Scientist print edition, 30 October). While climbing, Opportunity spent a lot of time with its solar panels tilted, which could have caused any dust to tumble off. www.newscientist.com /article.ns?id=dn6824   (514 words)

CNN.com - Scientist: Mars rock photo shows 'Holy Grail' - Jan. 27, 2004 CNN's Miles O'Brien reports that while NASA's Spirit rover is in rehab, Opportunity is sitting near rock formations on Mars that could be a 'Holy Grail' for geologists. Opportunity, on its third day on Mars, sent the Earth-bound mission managers an 8,000-by-3,000-pixel, 180-degree image of the area in front of it -- an image that could be zoomed in tight enough to identify individual grains of the dust covering the surface. Opportunity's Meridiani Planum landing site was chosen because it is believed to be full of iron-bearing hematite. www.cnn.com /2004/TECH/space/01/26/mars.rovers   (686 words)

Opportunity Mars Rover Rolls Off Landing Platform   (Site not responding. Last check: 2007-10-21) Erickson says Opportunity's immediate science objectives now will be to map the shallow crater around it, study exposed bedrock within the crater, and eventually crawl over the low crater rim onto the Plains of Meridiani. Opportunity and its twin rover Spirit on the other side of Mars are looking for geologic evidence that water once flowed on the planet, suggesting it could have supported life. Hematite is the mineral Opportunity came to find after an orbiting U.S. satellite had detected huge deposits of it on the Meridiani plain. www.voanews.com /article.cfm?objectID=945EE7B2-0195-457D-85E1DD78A1700D39   (515 words)

NASA - 'Two for Two': Opportunity Lands on Mars But, he said, "we resurrected one rover and saw the birth of another." Weiler also cautioned that Opportunity's landing is just "one more critical milestone" in the mission. Opportunity's landing site is on plains called Meridiani Planum within an Oklahoma-sized outcropping of gray hematite, a mineral that -- on Earth -- usually forms in the presence of water. Scientists plan to use the research instruments on Opportunity to determine whether the gray hematite layer comes from sediments of a long-gone ocean, from volcanic deposits altered by hot water or from other ancient environmental conditions. www.nasa.gov /vision/universe/solarsystem/INT_opportunity_update.html   (321 words)
