Plants on Mars

As part of a proposed mission that could put plants on Mars as soon as 2007, University of Florida professor Rob Ferl is bioengineering tiny mustard plants. He's not altering these plants so that they can adapt more easily to Martian conditions. Instead, he's adding reporter genes: part plant, part glowing jellyfish -- so that these diminutive explorers can send messages back to Earth about how they are faring on another planet.Right: Green-glowing Arabidopsis thaliana for a future pioneer of Mars? Rob Ferl and the University of Florida. The plants can be genetically wired to glow with a soft green aura when they encounter problems. Within a garden grouping, some plants could report (by glowing) low oxygen levels, while others might signal low water or, say, the wrong mix of nutrients in the soil. Thriving plants won't glow at all. They'll look like normal mustard. But plants struggling to survive will emit a soft green light, a signal to researchers that something is amiss. A camera onboard the lander would record the telltale glows and then relay the signal back to Earth. No humans are required on the scene -- a big advantage for such a far away experiment. The plants' designer genes consist of two parts: a sensor side to detect stress and a reporter side to trigger the glow

New exciting and to help humanity move asteroids’ out of the way self power project soon to be taken very seriously. With a straight face just that dead pan look. On May 1, 2009, during its fifth mission extension, Spirit became stuck in soft soil on Mars. After nearly nine months of attempts to get the rover back on track, including using test rovers on Earth, NASA announced on January 26, 2010 that Spirit was being retasked as a stationary science platform. This mode would enable Spirit to assist scientists in ways that a mobile platform could not, such as detecting "wobbles" in the planet's rotation that would indicate a liquid core. Jet Propulsion Laboratory (JPL) lost contact with Spirit after last hearing from the rover on March 22, 2010 and continued attempts to regain communications until May 25, 2011 bringing the elapsed mission time to 6 years 2 months 19 days or over 25 times the original planned mission duration.

The speculating within a paper published in Cornell University's online journal arXiv, that if there are stable orbits for photons, there is no reason why there could not be stable orbits for larger objects, such as planets. The problem is that these stable orbits would only exist once you have crossed the threshold of the event horizon, where time and space flow into one another.The event Horizon, at the lip of the black hole, is known as the point of no return. However speed, beyond the event horizon is another domain, known as the Cauchy horizon, where time and space return to stable states. It is inside the Cauchy horizon that life could exist, Dokuchaev argues in a paper published in Cornell University's online journal arXiv,However, the type of life that could exist in those conditions - where they would be subject to massive fluctuating tidal forces - would have evolved beyond ours. The life that could exist there would likely be a civilisation ranked as Type III on the Kardashev Scale. There are three levels to the scale with one being the lowest and three the highest. Humanity is still looking to attain Level 1 status; mastery of its own planet. 'Interiors of the super massive black holes may be inhabited by advanced civilisations... invisible from the outside,' he says. Though that is a spine-tingling thought, Dokuchaev's proposition can only ever remain theoretical. Because nothing can ever escape from a black hole due to its enormous gravitational pull, we will never know if it is true. Art club view question is did life develop and exist in subatomic particles of black hole if so they have to be fast what consists of definition of life probably to humans something that expands to develop this fit the bill perfectly as it on a paradox to what we know as matter define it bonds with out.

Eventual Inability.

That's a relief - there are many fewer 'mid-sized' Asteroids near Earth than was previously thought. There are roughly 19,500 -- not 35,000. But while the risk of impact is smaller, according to NASA, the majority of them remain to be found. Mid-sized, by the way, isn't small - it refers to asteroids in a size range between 330 and 3,300 feet wide, which could destroy a city-sized area were they to hit Earth. NASA's latest scan used the Wide-field Infrared Survey Explorer, or WISE and took two infrared scans of the entire celestial sky, scanning the entire sky twice in a series of infrared photos between January 2010 and February 2011. The scan aimed to find asteroids 'near Earth' - ie within 120 million miles.
NASA's scientists were cautious about the result, saying only that the risk to Earth could be 'somewhat less' now than they previously thought. Scientists also admit there could be 'up to a million' smaller asteroids that have not yet been detected - which could 'cause damage' if they hit Earth. What is definitely good news is that the likelihood of a 'planet-killer' - the mountain-sized asteroids in the 'large-sized' range, above 3,300ft - appears to have fallen more significantly. There are only 981 of these objects near Earth according to the latest estimates, and NASA has found 911 of them. The scenario, beloved of film directors, where a huge asteroid threatens all life on Earth now looks distinctly unlikely. All near-Earth asteroids that are as big as the one that wiped out the dinosaurs (around six miles across) are thought to have been found by NASA's scans, which use infrared to detect both 'light' and 'dark' asteroids. 'NEOWISE allowed us to take a look at a more representative slice of the near-Earth asteroid numbers and make better estimates about the whole population,' said Amy Mainzer, lead author of the new study, published in the Astrophysical Journal, and principal investigator for the NEOWISE project at NASA's Jet Propulsion Laboratory in Pasadena, Calif. WISE captured a more accurate sample of the asteroid population than previous visible-light surveys because it is difficult for visible-light telescopes to see the dim amounts of visible-light reflected by dark asteroids. 'The risk of a really large asteroid impacting the Earth before we could find and warn of it has been substantially reduced,' said Tim Spahr, the director of the Minor Planet Center at the Harvard Smithsonian Center for Astrophysics in Cambridge, Mass.
