Kepler’s Second Light: How K2 will work
4Michael Haas: K2 Mission at AAS on 07 Jan 2014
Mission Concept• Continuously observe ~10,000 LC and ~100 SC targets for 75 days• Turn to Earth and download science and engineering data• Move ~83 days along ecliptic plane and begin another campaign

Proposed Campaign Fields
• K2 Mission invited to 2014 Senior Review– If approved, K2 science observations planned to start in June, 2014
• Project solicits input on proposed K2 fields by Feb 1, 2014– http://keplerscience.arc.nasa.gov/k2

Spacecraft Jitter
Width of K2 point-spread function is only <5% larger than Kepler point-spread function across the entire field of view
K2 observation of 12th magnitude star taken from
30-min Full-Frame Image in
Coarse Point
Kepler Point-Spread Function in Fine Point

Photometric Precision
s-clipped, detrended and normalized
• Light curve for 12th magnitude star from mid-Dec test – Drift over 6 days held to 3 pixels (with more improvements to come)– Median 6-hr photometric precision is 87 ppm

Performance Demonstration
• Full-length demonstration campaign will start around Mar 10– FOV approximately RA = 06:47:00, Dec = +21:22:47– Project is soliciting targets for this campaign, due date is Feb 1, 2014– Details at Kepler booth and http://keplerscience.arc.nasa.gov/k2
