Kepler Completes Prime Mission and Begins Extended Mission
Today Kepler Space Telescope marks two milestones: the successful completion of its prime mission searching for exoplanets and the beginning of an extended mission that we expect to last at least four years, unfolding a census of exoplanets, the ones of greatest interest being other Earths that could already be in the data, awaiting analysis. Kepler's most exciting results are yet to come.

Small planets do not need metal-rich stars
A research team led by Lars A. Buchhave has studied the elemental composition of more than 150 Kepler stars harboring 226 Kepler planet candidates smaller than Neptune and found that the occurrence of small planets does not depend as strongly on the metallicity of the host star. This observation suggests that terrestrial-like planets may be widespread in the disk of our Galaxy, with no special requirement of higher metallicity stars for their formation.

The turbulent lives of stars
The stars are boiling! The reason is the energy generated in the center of the star that wants to escape. If this does not happen quickly enough, the star starts to ‘boil’ in the outer layers causing vibrations that result in light variations, like in the Sun. Such oscillations have now been discovered by Victoria Antoci and collaborators using the NASA spacecraft Kepler, but in a much hotter star. The scientists publish this in the most recent issue of “Nature”.

Kepler-14b, Supergiant, is orbiting one of the stars in a binary star system
Kepler-14b is a planet 8 times more massive than Jupiter, orbiting one of
the stars in a binary star system. The planet has a short orbital period of
just 7 days, while the two stars orbit each other with a much longer period
of about 2800 years. The light from the planet hosting star diluted by
its companion star significantly affects the derived
planetary parameters... and similar dilution effect could significantly affect the derived
planetary parameters of other planet discoveries.

Kepler discovery of a unique triply eclipsing triple star
Star HD 181068 , a 7th magnitude star almost visible to the naked eye is in reality a complex triple system in which three stars undergo mutual eclipses as each of the stars gets behind or in front of the others. The most luminous object is a red giant star around which a close pair of two red dwarfs orbits with a period of 45.5 days. The combined light from the three stars show sharp brightness decreases with a period of 0.9 days produced by the mutual eclipses of the close pair of dwarfs, while it takes 2 days for the close pair to pass in front of or behind the red giant.

First 43 Days of Kepler Data Released
NASA's Kepler Mission has released 43 days of science data consisting of brightness changes for more than 156,000 stars originally targeted in an ongoing search for Earth-like planets outside of our solar system. Astronomers will use the new data to determine if orbiting planets are responsible for brightness variations in several hundred stars. …Some show starspots, which are similar to sunspots, and a few produce flares that would sterilize their nearest planets. …The 28-member Kepler science team also is performing follow-up observations on a specific set of 400 objects of interest. …That data will be released to the scientific community in February 2011. ..."This is the most precise, nearly continuous, longest and largest data set of stellar photometry ever," said Kepler Deputy Principal Investigator David Koch of NASA's Ames Research Center in Moffett Field, Calif. "The results will only get better as the duration of the data set grows with time."
Kepler will continue conducting science operations until at least November 2012, searching for planets as small as Earth, including those that orbit stars in a warm habitable zone where liquid water could exist on the surface of the planet. Since transits of planets in the habitable zone of solar-like stars occur about once a year and require three transits for verification, it is expected to take at least three years to locate and verify an Earth-size planet. "The Kepler observations will tell us whether there are many stars with planets that could harbor life, or whether we might be alone in our galaxy," said mission science principal investigator William Borucki of Ames.

Kepler experienced a safe mode event on November 18. A safe mode is a self-protective measure that the spacecraft takes when something unexpected occurs. During safe mode, the spacecraft points the solar panels directly at the sun and begins to slowly rotate about a sun-aligned axis. The spacecraft automatically powered off the photometer and one redundant subsystem as a safety precaution. Engineers immediately began telemetry analysis to determine spacecraft subsystem health, and root cause determination of what triggered the safe mode. This safe mode occurred when the team was preparing to download another month of scientific data from Kepler. The scientific data was not in danger and was downloaded successfully via the NASA Deep Space Network on November 19. Engineers verified nominal performance of all of Keplers systems and successfully recovered the vehicle from safe mode. Science data collection was resumed by the evening of November 20.

Kepler's Search for Small Worlds Hampered by Noisy Electronics.
By Debra Werner, Space News. Excerpt: MOUNTAIN VIEW, Calif. ... In spite of electronic components that are creating extraneous noise on board the Kepler space telescope, NASA officials are confident the mission will be able by 2011 to either detect Earth-size planets or reveal that those planets are uncommon, said James Fanson, Kepler project manager at the Jet Propulsion Laboratory in Pasadena, Calif. During an Oct. 29 meeting here, William Borucki, Kepler principal investigator at the NASA Ames Research Center, told members of the NASA Advisory Council that noise produced by three of the 42 amplifiers used to boost signals from the telescopes charge-coupled devices was creating image artifacts, or features present in the Kepler data sets that reflect noise rather than an accurate picture of the stars. "Those image artifacts are slowing our data analysis," Borucki told the panel. "Mitigation work to flag and correct those problems will be complete in 2011."
That does not mean, however, that Kepler will be unable to discover Earth-size planets before 2011, Fanson told Space News Nov. 5. Data obtained last summer ... indicated that the instrument is sensitive enough to detect far smaller objects, including planets the size of Earth. …"Kepler measurements are at least 100 times more sensitive than measurements obtained from telescopes on Earth," he said. The quality of the light curve is so extraordinary, in fact, that one mission official wept with joy when he saw the data, Fanson added….
