This NASA Discovery mission is to be launched in June 2008 and will search for Earth-size and smaller planets. Launch was originally scheduled in 2007 but delayed by 8 months due to "funding constraints".

Are there known transiting exoplanets in that piece of sky for cross-checking purposes?

Are there known transiting exoplanets in that piece of sky for cross-checking purposes? I know two exo-planets have been discovered by the use of the transit method. However, the only planet that could be used to calibrate or test such technologies at the current time is Venus. Scientists used the June 8, 2004 transit to test alot of devices and technologies that Kepler and future missions will use. The most important one was done by ACRIM which showed a orbiting spacecraft CAN detect a minute drop (about 0.1%) in a parent star's (the Sun!) light reaching a detector. Good news though: There will be another transit on June 6, 2012. I bet this will be used as well! -------------------- I call heaven and earth to witness against you this day, that I have set before thee life and death, the blessing and the curse; therefore choose life, that thou mayest live, thou and thy seed.

Good news though: There will be another transit on June 6, 2012. I bet this will be used as well! It seems to me that many more opportunities happen than this. We need only look at the light curve of medium to large asteroids as the Earth, or Venus, or Mars, or Jupiter transit the Sun from their locations. There must be dozens of such events per year. More if you want to look at smaller objects. |
