Default 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.

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. (must be the unusually high vacuum of 1e-181e-21
bar)

Puffing your own article without saying that you are doing so is
despicable.

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.
