15th Nov 2013: Q12 updated.
Additional stars are included in the latest Q12 (Data Release 21) dataset. The data were processed with PDC msMAP. Please read the release notes for DR 21: http://kasoc.phys.au.dk/docs/release_notes/Data_Release_Notes_21_20130508.pdf.
12th Nov 2013: Q16 is available for download.
Both the "FITS" and "ASCII" formats of Q16 (Data Release 22), together with the TPD files (also as bundles) are available for download. Please consult the associated release notes, which are available in the Information - Documentation section.
29th Aug 2013: KASOC Scheduled Downtime
During the next few days (Thursday and Friday) there may be times where the KASOC website is unavailable in periods. This is due to some maintenance of the systems. We apologize for any inconvenience this may cause, and will try to keep the downtime to a minimum.
11th Dec 2013: Kepler Mission Manager Update: Invited to 2014 Senior Review
The Astrophysics Division at NASA Headquarters has invited the Kepler project to submit a funding proposal for a two-wheel mission, dubbed K2, to its 2014 Senior Review of operating missions.

26th Nov 2013: Kepler's Second Light: How K2 Will Work
The conception illustration depicts how solar pressure can be used to balance NASA's Kepler spacecraft, keeping the telescope stable enough to continue monitoring distant stars in search of transiting planets.
In May, Kepler lost the second of four gyroscope-like reaction wheels, ending new data collection for the original mission. A new mission concept, dubbed K2, would continue Kepler's search for other worlds, and introduce new opportunities to observe star clusters, young and old stars, active galaxies and supernovae.
Using the sun and the two remaining reaction wheels, engineers have devised an innovative technique to stabilize and control the spacecraft in all three directions of motion. This technique of using the sun as the 'third wheel' to control pointing is currently being tested on the spacecraft.
To achieve the necessary stability, the orientation of the spacecraft must be nearly parallel to its orbital path around the sun, which is slightly offset from the ecliptic, the orbital plane of Earth. The ecliptic plane defines the band of sky in which lie the constellations of the zodiac.
K2 would study a specific portion of the sky for up to 83 days, until it is necessary to rotate the spacecraft to prevent sunlight from entering the telescope. Each orbit or year would consist of approximately 4.5 unique viewing periods or campaigns.
The K2 mission concept has been presented to NASA Headquarters. A decision to proceed to the 2014 Senior Review – a biannual assessment of operating missions – and propose for budget to fly K2 is expected by the end of 2013.
