Recent studies of Kepler Solar-like oscillators demonstrate that ages predicted by gyrochronology and asteroseismology are not always compatible. The postulated gyrochronological relation between rotation period, mass and age for F, G and K main-sequence stars may be an over-simplification of the underlying physics. Additional targets with photometric rotation periods and precise ages are needed to resolve the tension between gyrochronology and asteroseismology. K2 and TESS will provide rotation periods and asteroseismic ages for hundreds of stars, some of which will lie in clusters. Both of these surveys will require sophisticated methods for photometry extraction, treatment of systematics and rotation period measurement. A thorough, statistically rigorous approach will be required in order to combine information across surveys and stellar populations. We demonstrate new methods for the extraction of rotation periods from noisy data and discuss the prospects of these missions and the methods required to maximise their impact on the advancement of gyrochronology.
