When you're working in the yard this summer, take a look up: Using a satellite, NASA scientists are paying attention to how healthy your lawn and garden are. Next month, the agency plans to launch the Orbiting Carbon Observatory-2. Its primary aim is to create a global map of carbon sources and carbon sinks. The OCO-2 mission will provide the most detailed map of photosynthetic fluorescence - that is to say, of how plants glow - ever created. Using this data, scientists should be able to estimate how quickly the world's plants are absorbing carbon from the atmosphere. The applications of the project are wide-ranging, but the science is easy enough to understand. During photosynthesis, a plant absorbs light, then immediately re-emits it at a different wavelength. This is known as fluorescence. In a laboratory setting, botanists can measure the intensity of fluorescence to estimate how actively a plant is photosynthesizing. A satellite could, in theory, detect the light emitted by the world's plants to estimate how much carbon the plants are absorbing. But there has always been a big, fiery problem: the sun.Continue here More discoveries you might want to know about

Info Mag Koyal Group Mars Rover Marks an Unexpected Anniversary With a Mysterious Discovery Ten years ago, NASA's Opportunity rover bounded to the surface of Mars for what was planned to be a three-month exploration. Opportunity is still going today - and still making discoveries. The latest, scientists said on Thursday at a news conference celebrating an anniversary none had expected 10 years ago, is a small rock that seemingly appeared out of nowhere. The rock, whose chemical composition was also unexpected, appears in an image taken Jan. 8. There was no rock in a picture taken of the same spot less than two weeks earlier. "This is strange," said Steven W. Squyres, the principal investigator for Opportunity, during the NASA news conference. But he added, "We don't think anything particularly exotic happened here." Dr. Squyres said the most likely explanation was that as the rover pirouetted at an uphill location, its lame right front wheel, which has not turned for years, dragged across the rock and flicked it out of the ground to its new location. The scientists have not yet spotted the divot where the rock popped out, but that spot may be obscured by the rover's solar panels. Year after year, Opportunity goes farther than anyone dreamed. The expectation had been that it would drive about a kilometer - six-tenths of a mile - before dust accumulated on the solar panels and the batteries drained. Unexpectedly, fortuitous winds periodically cleaned off the solar panels, and Opportunity, as well as its twin, Spirit, continued to operate. Spirit got stuck in a sand dune 2009 and then fell silent in 2010 after it was not able to point its solar panels toward the sun during the winter months.

The live show MythBusters: Behind the Myths, starring Jamie Hyneman and Adam Savage, co-hosts of the Emmy-nominated Discovery series "MythBusters," returns to the The Bushnell's Mortensen Hall for one night only on Wednesday, December 3 at 7:30 p.m. Tickets are on sale now. The show promises to be an outrageous evening of entertainment featuring brand new onstage experiments, behind-the-scenes stories and some of your all-time favorites. A new immersive video experience will keep you bolted to your seat. MythBusters: Behind the Myths brings you face-to-face with the curious world of Jamie and Adam as the duo matches wits on stage with each other and members of the audience. The show played a first sold out date at The Bushnell in March 2012. Tickets for Mythbusters: Behind the Myths are available at The Bushnell box office, 166 Capitol Avenue in Hartford, by phone at 860-987-5900, and online at bushnell.org. One of the most highly regarded and watched series on the Discovery Channel, "MythBusters" is now in its twelfth season. Co-hosted by Hyneman and Savage, the show mixes scientific method with gleeful curiosity and plain old- fashioned ingenuity to create its own signature style of explosive experimentation - and the supporting or de-bunking of urban myths that we live with day to day.
