MSNBC quoting Geoffrey Marcy, a member of the Kepler science team:
“Three weeks ago, the Kepler team announced the first two Earth-size planets. Only Kepler has sensitivity to Earth-size planets. [Now we have announced] the first Mars-size planet around another star. … These discoveries by Kepler will mark an historic moment in the history of science, approaching the trans-oceanic voyages of the 15th century and the first steps on the moon. Kepler is indeed finding new worlds.”
The Kepler mission is an attempt to log and briefly study as many exoplanets as possible. I wonder if we as a species will one day make it to one of these worlds?
