  Solar-like oscillations are excited in cool stars with convective envelopes
and provide a powerful tool to constrain fundamental stellar properties and
interior physics. We provide a brief history of the detection of solar-like
oscillations, focusing in particular on the space-based photometry revolution
started by the CoRoT and Kepler Missions. We then discuss some of the lessons
learned from these missions, and highlight the continued importance of smaller
space telescopes such as BRITE constellation to characterize very bright stars
with independent observational constraints. As an example, we use BRITE
observations to measure a tentative surface rotation period of 28.3+/-0.5 days
for alpha Cen A, which has so far been poorly constrained. We also discuss the
expected yields of solar-like oscillators from the TESS Mission, demonstrating
that TESS will complement Kepler by discovering oscillations in a large number
of nearby subgiants, and present first detections of oscillations in TESS
exoplanet host stars.
