My brother and I enjoyed watching Reading Rainbow as kids, so it's a delight for me to have had a guest post published on their blog last week. I wrote for them about how kids (with the help of their parents) can follow the adventure of the Curiosity mission through the release of their raw images.

We're now less than two weeks away from comet C/2012 S1 (ISON) reaching perihelion and, if we’re honest, we are still none the wiser as to how the situation might play out!

A perfect launch on an Atlas V rocket has sent MAVEN on her way to Mars today at 10:28 PT (18:38 UT). Today's on-time launch puts the mission on course for a September 22, 2014 arrival at Mars.

Bright and early this morning, we NASA Social folks met at the Kennedy Space Center Visitors Complex for a tour of the space shuttle Atlantis. This is the first shuttle I've seen in person, and it was a stunning sight to see.

The Advanced Stirling Radioisotope Program (ASRG) was just cancelled by NASA. This was to be the saving grace for Plutonium-238 availability, as it was a much more efficient way to generate electricity than classic RTG systems.

MAVEN is just about to launch! The mission has just released their launch press kit. This post summarizes the press kit's high points, and hopefully answers most of your questions about NASA's next Mars orbiter, scheduled for liftoff Monday at 10:28 PT / 13:28 ET / 18:28 UT.

It's time for my annual roundup of reviews of space-themed books for children! I have lots of fiction and nonfiction books to recommend, for toddlers to teens.

It took months of work (and no wonder) but the wait was worth it: here is Cassini's spectacular view of Saturn, captured on July 19, 2013, as Cassini passed through Saturn's shadow. If you're a little confused by the image, I'm here to help: I've posted a video explainer.

Episode 5 focuses on Mars, the planet that has stubbornly refused to conform to the wishes of humanity for hundreds of years, from Lowell to Sagan. Grab your cosmo and join our discussion of 'Blues for a Red Planet.'

NASA’s shrinking budgets for planetary exploration may force it to decide between continued funding for the Saturn Cassini mission and the continued funding for its Mars missions.

Yesterday, the Mars Orbiter Mission was commanded to perform a rocket burn that would have raised the apogee of its orbit around Earth. The spacecraft began its burn, but underperformed. ISRO has planned a supplemental burn for November 12 at 05:00 IST (today at 15:30 PT / 23:30 UT) in order to make up the deficit.

In the face of disaster, the search for answers and ways to help continues, on the ground and in space.

The Mars Orbiter Mission completed its first, second, and third of six planned maneuvers in Earth orbit successfully last week. However, the fourth maneuver, conducted on Sunday at 12:36 PST / 20:36 UTC / Monday 02:06 IST, failed to lift the apogee of the orbit as high as planned.
