China's now famous 'Yutu' moon rover has set sail for what promises to be breathtaking new adventures on Earth's nearest neighbor, after completing a final joint portrait session with the Chang'e-3 lander that safely deposited her on the lunar surface only a week ago.
Yutu's upcoming journey marks humanity's first lunar surface visit in nearly four decades since the Soviet Union's Luna 24 sample return vehicle visited. America's last lunar landing mission with the Apollo 17 astronauts departed 41 years ago on Dec. 14, 1972.
Two astronauts are oh-so-close to fixing the International Space Station cooling system that shut down Dec. 11. NASA astronauts Mike Hopkins and Rick Mastracchio will head “outside” on a spacewalk around 7:10 a.m. EST (12:10 p.m. UTC) to replace a faulty pump that led to the problem.
The spacewalkers were so quick on their first outing (on Saturday, Dec. 21) that they accomplished many of the tasks planned for their second spacewalk. They unhooked the first pump module and stowed it safely, then elected to wait until their second to retrieve the replacement pump, swap it in and turn it on.
Below the jump, here are some things to watch for — including why Hopkins is getting a ride on the Canadarm2 robotic arm this time instead of Mastracchio.
Why pick up a low quality, wobbly telescope from the department store when you can craft your own – just like Galileo, and all the great astronomers from history. For a minor investment, you can build a worthy telescope out of spare parts and high quality kits. (...) Read the rest of Astronomy Cast Ep. 327: Telescope Making, Part 1: Toys and Kits (46 words)

Cassini couldn’t make it to the mall this year to do any Christmas shopping but that’s ok: we’re all getting something even better in our stockings than anything store-bought! To celebrate the holiday season the Cassini team has shared some truly incredible images of Saturn and some of its many moons for the world to “ooh” and “ahh” over. So stoke the fire, pour yourself a glass of egg nog, sit back and marvel at some sights from a wintry wonderland 900 million miles away…
Just to demonstrate how far-reaching that Saturn snapshot of Earth this year was, the Skopje Astronomical Society (from Macedonia) made a video celebrating “The Day The Earth Smiled”, when the Cassini spacecraft looked at Earth on July 19 and thousands of people made pictures and video showing what they were doing at that time.
Watch the video, then look at some stunning pictures of Saturn below the jump.

Lovers of planetary action rejoice; the king of the planets is returning to the evening skies.
One of the very first notable astronomical events for 2014 occurs on January 5th, when the planet Jupiter reaches opposition. You can already catch site of Jove in late December, rising in the east about an hour after local sunset. And while Venus will be dropping faster than the ball in Times Square on New Year's Eve to the west in early 2014, Jupiter will begin to dominate the evening planetary action.(...)

After seeing Phobos imaged from the surface of the Red Planet by Mars Curiosity, now we’re lucky to get a close-up treat: here’s a video showing Mars Express images of the Martian moon over the last 10 years. The images reveal mysterious grooves running through the small moon, which is 13.5-miles (22 kilometers) in diameter, and scientists still aren’t sure what’s going on.

Kids’ drawings are the best, as astronaut Karen Nyberg proudly shows in her latest mini-quilt piece. The astronaut — who just spent six months in orbit during Expedition 36/37 — is also a prolific quilter and drew inspiration from her son, three-year-old Jack, in this quilt posted on Pinterest. The drawing shows how quickly Jack changed during her mission, she wrote.

The ghosts of spacewalks past did not haunt the quick-working pair of astronauts who began replacing a faulty ammonia pump on the International Space Station today (Dec. 21).
Unlike a difficult spacewalk to do a similar repair in 2010, NASA astronauts Rick Mastracchio and Mike Hopkins were so far ahead of schedule that they began doing tasks scheduled for the second in their expected trio of spacewalks.
In better news yet for the spacewalkers, a water leak in Hopkins’ spacesuit this past July — one that sent astronauts scrambling back to the airlock for safety — did not happen again, showing that the part replacement NASA directed had worked. An unrelated water issue in Mastracchio’s suit, however, made agency officials decide to delay the next spacewalk one day to Dec. 24.
