Kepler Planet-Hunting Space Telescope Launches
The Kepler planet hunting space telescope has successfully launched
from the Kennedy Space Center on board a Delta II rocket. When Kepler is settled in low Earth orbit it will spend three and a half years looking for Earth sized planets. http://www.associatedcontent.com/art...pe.html?cat=15 |

Thankfully there were no good reasons to sabotage the Kepler mission, as having clearly existed with the OCO mission. According to Wikipedia, in addition to our heading towards Sirius at 7.6 km/s, seems we’re also headed towards “Cygni A” at 64 km/s, and it’s only 11.4 ly distant as is. Obviously stellar motions (including our own) are a wee bit more complicated then that. A large red dwarf with those likely planets is what the spendy Kepler mission is going to catalog the obvious, that other stars accommodate planets. “Cygni A” may have a large outer planet with a 7.5 year orbit. The smaller “Cygni B” could also have planets, just like a much larger version of Jupiter would have moons as possibly larger than Earth. Eventually we’ll get to within 9 ly of “Cygni A/B”, or rather it’s “Cygni A/B” that’s coming towards us and Sirius at the same time. Our Selene L1 along with an artificial shade would have been an ideal location for such observations as of 4+ decades ago. According to our Apollo missions, our Selene/moon L1 is quite passive, not the least bit toasty or receiving any kind of unusual X-ray or gamma from our naked Selene/moon.

Anyway, who wants to read an article by an author who manifestly knows less than Wikipedia, Florida Today, space.com, etc., etc.? Kepler will not settle into low Earth orbit, since it has been injected into a heliocentric orbit of slightly larger semi-major axis than ours. Since LEO is easier to reach, one can presume that Kepler in LEO (possible, I suppose, if the launcher worked badly enough) would at best be significantly less capable than intended. -- (c) John Stockton, nr London, UK.
