Learn easy things to look for in the night sky, and about the electromagnetic spectrum from gamma rays to radio waves in the video of class 2 of Bruce Betts' Introduction to Planetary Science and Astronomy class.
When our future astronauts splash down into the Pacific Ocean aboard an Orion capsule, Mike Generale, NASA, and the U.S. Navy will be waiting for them.
After more than two months of very slow driving due to concern about the wheels and time spent choosing whether to enter "Dingo Gap" or not, Curiosity has safely crossed the dune and resumed longer drives, achieving 75 meters and crossing the 5-kilometer mark on sol 540.
Cassini flew past Phoebe on June 11, 2004, on its way to entering Saturn orbit. The flyby was almost perfect but overexposure of some images have prevented color mosaics from being produced. Even though Phoebe's body is gray and dull in color, the absence of color images always provoked me. By using VIMS data, I have now produced color mosaics.
A terse Xinhua news report posted today says there may be some sign of life from Yutu, now that the Sun has risen on the third lunar day since Chang'e 3 landed. It is frustratingly non-specific. UPDATE: Amateur radio operators have detected a radio signal from the rover.

Promoting the story of Yutu to the Chinese public through social media: a successful case of science outreach.
A hundred days after launch, India's Mars Orbiter Mission is doing just fine, and so is NASA's MAVEN.

There have been tons and tons of HiRISE images of the Curiosity landing region, and it has taken quite a lot of work for me to find, locate, and catalogue them. This post is a summary of what I've found.
To paraphrase Forrest Gump, the Discovery program is like a box of chocolates – you never know what you’re going to get. The creativity of the scientific community has given us a wide assortment of missions in the past and is likely to surprise and delight us again.

In the storied history of the Mars Exploration Rovers (MER) mission, January 2014 will likely be remembered as one of the most memorable months of all.
It's with great sadness that I report that the Goddard Space Flight Center team has determined that we will not be able to regain control of the venerable spacecraft ICE/ISEE-3 when it passes by Earth this year, after a 30-year journey around the Sun.
Slate's Misleading Hit Piece on the Future of NASA
Instead of a thoughtful essay, they published an uninformed screed
A response to Slate's recent piece on the future of NASA, correcting many of its myths and misconceptions about how NASA works.
The Mars Exploration Family Portrait is expanding to cover the entire solar system! But before we proceed, I'm asking for feedback.
A few days ago, Curiosity looked westward after sunset and photographed Earth setting toward the mountainous rim of Gale crater.
