Map of Observations
NOTE: The K2 mission is a follow-on to the Kepler mission, operated when the telescope was reduced to two reaction wheels.
The K2 mission observed 100 square degrees for 80 days each across 20 different pointings along the ecliptic. The mission began when the original Kepler mission ended due to loss of the second reaction wheel in 2011. The design of the K2 mission needed to periodically change the telescope's pointing to sample a variety of Galactic sight lines to maintain a reasonable pointing stability, balanced via the solar wind. While the mission continued to observe stars to detect transiting exoplanets, the variety of pointings enabled a wider variety of astrophysical research projects; in fact the K2 mission was fully Guest Investigator-driven. The mission produced the same pixel-level and lightcurve data products as the original Kepler mission, however, the mission's planet search pipeline was not run. A number of community-contributed lightcurves with pointing drift errors greatly mitigated were provided as High Level Science Products, and can complement the mission data in many science cases.

The K2 Handbook describes the engineering challenges and mitigation strategies of the K2 mission. It should be used in conjunction with the Kepler Archive Manual, Kepler Instrument Handbook, and Kepler Data Characteristics Handbook.5 MB
