Enough bad news, enough gloom and doom. You remember that Asteroid 99942 Apophis
that we were afraid might hit Earth in 2029? Ain't gonna happen. But it will get close enough for Earth's gravity to alter its orbit and there's a chance it could hit the next time around in 2036.
But only a tiny chance: "less than 1 in 45,000 using standard dynamical models
". according to NASA. Oh wait... NASA just got skooled
by a 13-year-old German Astronomy Geek who says the chances are more like 1 in 450
. Still a tiny chance, and the official numbers were only off by a factor of 100
. Oh yeah, we're doomed.

In honor of this morning's impressive lunar eclipse
, another moon-photo post: For decades you had to be a scholar or specialist to get access to the original Apollo flight films, most of which have been stored in freezers at Houston's Johnson Space Center. Now Arizona State University and NASA are scanning the negatives with high-resolution equipment and creating an online digital archive
of downloadable images for the general public.
Here are the first few
, from Apollo 15.

probe launched Saturday
from Cape Canaveral, destination Mars. Its mission is to investigate polar ice. This probe is unique for a couple of reasons: first, it will face a traditional parachute-and-retro-rockets landing, unlike previous endeavors.
Second, it will be landing far north of any previous mission. Previous Mars missions have had mixed success, with only about half
successfully making it to their destination. It is scheduled to land in May, 2008.

Titan Sea and Lake Superior
This movie, comprised of several detailed images taken by Cassini's radar instrument, shows bodies of liquid near Titan's north pole. These images show that many of the features commonly associated with lakes on Earth, such as islands, bays, inlets and channels, are also present on this cold Saturnian moon. They offer strong evidence that larger bodies seen in infrared images are, in fact, seas. These seas are most likely liquid methane and ethane. Radar Shows Evidence of Seas

Rep. Ben Bridges (R-Cleveland, GA) is in trouble.
A recent memo
from his office -- one circulated this week
by Warren Chisum
, a ranking member of the Texas state legislature -- has caught the attention of the Anti-Defamation League
. They are not pleased
. And they're not alone
. Why? Because in his memo, Rep. Bridges
of a perennial anti-evolution education bill
in the Georgia State House -- claims that "so-called ’secular evolution science’ is the Big Bang, 15-billion-year, alternate ‘creation scenario’ of the Pharisee Religion."
And that's not all. It would appear that Rep. Bridges is getting his information (and templates
for his legislation
) from www.fixedearth.com
-- a website dedicated not only to the removal of pro-evolution education from schools, but to the idea that "[t]he Earth is not rotating...nor is it going around the sun." Because you see, it's all part of the Copernican Deception
, a massive conspiracy propagated by Christian Zionists
and ... Madonna

Hubble's ACS Has Died.
Hubble's Advanced Camera for Surveys
has apparently gone into safe mode, with little hope of return. The ACS was installed in 2002, and added amazing upgrades to Hubble's imaging capabilities. Though its lifespan was only projected at five years, scientists had hoped it would hold out longer. Though a final shuttle servicing mission is scheduled for 2008, the mission objectives plate
is already too full to consider its repair. Alas, more of those beautiful pictures (as well as extended research capabilities) will have to wait until the James Webb Space Telescope
is launched in 2013.
