The K2 mission is an extension of the Kepler mission, utilizing the Kepler spacecraft to continue exoplanet and astrophysics research. It operates by observing target fields along the ecliptic, providing long-term, high-precision photometric data for thousands of objects. Early results show a photometric precision of 400 ppm in 30-minute observations and 80 ppm over 6 hours. K2 offers a unique survey between Kepler and TESS, enabling pre-launch exoplanet target identification for JWST. The mission includes studies of young open clusters, bright stars, galaxies, supernovae, and asteroseismology. K2's key science goals include exoplanet characterization, open cluster studies, star-forming regions, variable extragalactic sources, and microlensing observations. It will observe approximately 40,000 targets per year, with a focus on transiting exoplanets, young stars, and stellar evolution. K2's photometric precision is expected to be far better than ground-based telescopes, enabling discoveries of high-value transiting exoplanets and insights into stellar populations. The mission is community-driven, with target selection based on peer-reviewed proposals. K2 will provide a legacy archive of data for the scientific community, including time-series data for exoplanet studies. Early science results demonstrate K2's ability to detect transiting exoplanets, such as WASP-28b, with high precision. The mission is expected to continue observing new fields every three months, offering a unique opportunity for astrophysical research. K2's operations are designed to maximize scientific return, with a focus on long-term observations and data quality. The mission is a low-cost space astrophysics mission that will advance our understanding of stellar evolution and extragalactic science.The K2 mission is an extension of the Kepler mission, utilizing the Kepler spacecraft to continue exoplanet and astrophysics research.
