The Kepler Mission is explicitly intended to appraise our area of the Milky Way solar system to unearth hundreds of Earth-size and smaller planets and additionally to determine the scope of the hundreds of billions of stars in our galaxy that may have such planets. The mission is distinctive from earlier ways of looking for planets because it will watch for the “transit” signature of planets. The scientific objective of the Kepler Mission is to examine the framework and variety of planetary systems, with a specific pre- eminence on the identification of Earth-size planets. The mission will also include the Wide-Field Infrared Survey Explorer “WISE”, which will chart the galaxy in long wavelengths, watching for star creating areas and remote high-red shift galaxies.
The NASA Astrobiology Institute was founded in 1998 to bring about combined research and development in astrobiology. The Exobiology Branch of NASA administers analysis in Exobiology attempting to increase our comprehension of the source, development, and apportionment of existence in the universe. The NASA Origins program assignment is to comprehend and defend our home planet, to research the Universe and hunt for life, and also to motivate our subsequent generation of voyagers.
Kepler’s photometer, which is a tool that gauges the brightness of light, will function like a mammoth camcorder with a 37 inch width lens, operating through space. Kepler would then be a logical conduit to the next comprehensive hunt for habitable planets and existences, the so called “Terrestrial Planet Finder”. A planet imaging operation intended for a 2010 launch which will benefit from data Kepler can supply about the likeliest positions in the solar system to find Earth-sized planets. Meanwhile the Kepler mission will study about 100,000 stars in an area of sky on the bearing of the constellation Cygnus for around 4 years, making brightness computations every 15 minutes, in the expectation of detecting the elusive transits. The spacecraft will be pointed towards Earth once a month to download its science information to NASA’s Deep Space Network, a mass of antennas encircling the globe that aid planetary and astronomical operations.
The transit approach will be used by Kepler to discover these extrasolar terrestrial planets, which is a means by which studies the diversity of brightness of a specific star when a large entity, such as a planet passes in front of the star. Transits take place when planets in their orbits encircling their guardian stars cross the line of vision among us or in this case, the cameras located within the spacecraft and the star. Each transit will cause the star to darken faintly in luminosity. An intermittent drop in light strength may conclude the company of an concealed planet moving across the front of the star hindering some degree of light output.
The Keck telescopes are a division of NASA’s Origins project, which also contains the TPF and the SIM operations. Each of the telescopes have a reflector with a width of about 10 meters. When merged the telescopes will be capable of working as a single telescope with a width of hundreds of meters. The observatory will be efficient at taking images 100 times more comprehensive than the Hubble Space Telescope.
The Kelper mission will study the extended solar locality to discover and distinguish hundreds of terrestrial and bigger planets in or near the ‘habitable zone’, characterized by scientists as the distance from a star where liquid water can subsist on a planet’s surface. Exclusively in the last few years have the technologies required to conduct a quest for small rugged, or earthly, planets with high accuracy reached maturity. In 10 years astronomers have discovered around 150 extrasolar planets, and the proportion is speeding up each year. Currently, observatories such as the Keck telescopes, which are ground based mechanisms, and the Spitzer telescope which was constructed in the expanse of Space itself, will assist astronomers in their hunt for extrasolar planets.
The Kepler mission is attractive in its straightforwardness in the understanding that it will study a broad area of sky for an extended period. The mission is fuelling growing exhilaration between space scientists following the discovery of more than three hundred planets orbiting additional stars in the past Fifteen years. The program is anticipated to uncover fifty to sixty extrasolar planets with a equivalent distance from their guardian stars as the World is from the Sun.
The Kepler Mission, which was originally scheduled for a March 5th launch, will now be launched on Friday, March 6, from Pad 17-B at Cape Canaveral Air Force Station in Florida. NASA have stated that the Kepler Mission will have two launch windows that day, from 10:49 – 10:52 pm and 11:13 – 11:16 pm EST. Delta II rocket will be the launch vehicle of the Kepler Mission.
