  Space photometric missions have been steadily accumulating observations of
Cepheids in recent years, leading to a flow of new discoveries. In this short
review we summarize the findings provided by the early missions such as WIRE,
MOST, and CoRoT, and the recent results of the Kepler and K2 missions. The
surprising and fascinating results from the high-precision, quasi-continuous
data include the detection of the amplitude increase of Polaris, and exquisite
details about V1154 Cyg within the original Kepler field of view. We also
briefly discuss the current opportunities with the K2 mission, and the
prospects of the TESS space telescope regarding Cepheids.
