On July 17th, NASA's
Wide-field Infrared Survey Explorer (WISE) satellite
completed its first survey of the entire sky viewable from Earth. After just seven months in orbit, WISE -- a precursor to the planned
James Webb Space Telescope -- has returned more than a million images that provide a close look at
celestial objects ranging from
distant galaxies to
asteroids. The first release of WISE data, covering about 80 percent of the sky,
will be delivered to the astronomical community in May of next year, but in the meantime we can see some of the images and animations that NASA has released to date: Galleries

"Standard orbit, aye, sir." Following a nail-biting ring-plane crossing and 96-minute engine burn,
Cassini has arrived, and is now in orbit around Saturn, 84 light-minutes away, sending in
the first closeup pictures of the planet's rings. Also see the Planetary Society's
details on the Orbit Insertion, Spaceflight Now's
mission updates in weblog-like format, and
raw images from the spacecraft as they come. Kudos, JPL! (Aside: the press has yet to tire of
Lord of the Rings references.)

Far, far away. Today, Voyager 1 will reach 90
AU from the sun, around which distance it is expected to cross the "termination shock," finally crossing into the fuzzy boundary between the
heliosphere and true
interstellar space. (Yes, it's taken
that long to get there.) Some even think that
the termination shock has already been reached, but then re-expanded past the spacecraft. Tears need not be shed yet for these distant explorers:
both Voyagers have juice till about 2020, and the mission remains
very much alive. (No word, however, on a possible
return to the Creator.)

Asteroid orbits Enter the designation or name of any asteroid or comet, and a 3D orbit visualization tool will appear for that object.
If Chicken Little had this link he might have calmed down a little. Or not...Find out if your favorite asteroid is about to rock your world.
