We have an amazing opportunity to change the field of exoplanet characterization by finding Super-Earths transiting bright nearby stars. Our HARPS radial-velocity survey has detected more than 50 low-mass planets in the solar vicinity, most of them being short period Super-Earths having a large transit probability. We propose an Exploration Science Program of 500 hours to detect the few of them that transit their host star. These detections will bring exoplanetology into the realm of terrestrial planets. The expected harvest of the proposed project is the detection of 1 - 2 transiting Super-Earths and 1 transiting hot Neptune. Future ambitious transit surveys like Kepler should detect much more low-mass planets, but the faintness of the target stars means thorough characterization of detected Kepler planets will not be possible with existing or near-future instruments like JWST. On the contrary, the few planets that will be detected by the proposed project all will be exquisite targets for high S/N follow-up studies. In particular, they will enable the first studies of the atmospheric properties and habitability of terrestrial extrasolar planetsE
