What We Know About the Russian Meteor Event [UPDATED]
We have the technology to provide warning about these potential disasters
Preliminary estimates show that the meteoroid was 15 meters wide and weighed roughly 8000 tons. The resulting airburst would have the equivalent yield of about a 1/2 megaton explosion.
Damien Bouic received some well-deserved recognition from the Chemcam team for his great Curiosity image processing work.
A large meteor streaked through the skies above Russia on the morning of Feb 15th, causing a deafening sonic boom that shattered windows and injured hundreds.
Brand new information about the effects of the across-the-board cuts known as Sequestration, if they were to be enacted.
Emily Lakdawalla and Courtney Dressing talked about just how common Earth-sized exoplanets may be in our neighborhood. Watch the replay here.
How come Hubble's pictures of galaxies billions of light years away are so beautifully detailed, yet the pictures of Pluto, which is so much closer, are just little blobs? I get asked this question, or variations of it, a lot. Here's an explainer.

We have been seeing lots of small light-colored veins crossing through the outcrops here on Matijevic Hill, and we have tried to get a handle on the composition of these veins by doing multiple offsets with the APXS. It appears that the small veins are calcium sulfate, as best we can determine.

Bill Nye traveled to Washington, D.C. with friend and Planetary Society board member Neil deGrasse Tyson
Bill Nye and Neil deGrasse Tyson spoke to the House Science committee about the importance of space and scientific research. Bill Nye also visited with Congressman Culberson and Congressman Wolf's chief of staffabout supporting NASA's Planetary Science Program.
With the Landsat Data Continuity Mission scheduled to launch on Monday, there's been a lot of Tweeting about Landsat, and through one such Tweet I learned about a resource that I hadn't known existed before: the LandsatLook Viewer. This is a graphical interface to more than a decade worth of Landsat data, a tremendous resource for anyone interested in Earth's changing surface, natural or manmade.
Join us this week as we feature our guest, Dr. Paul Hayne from JPL. Dr. Hayne studies snow and ice on Mars, extreme temperatures of the Moon, and is on the Cassini science team. He also founded the group Young Scientists for Planetary Exploration to help organize early-career scientists to be aware of the politics of space.
With its robot nose to the Martian grindstone, Opportunity completed its ninth year of working on Mars in January, making another significant science discovery in tiny white veins on Matijevic Hill as the Mars Exploration Rover (MER) mission rolled on into Year 10.
