Around the world in four days: NASA tracks Chelyabinsk meteor plume
Atmospheric physicist Nick Gorkavyi missed witnessing an event of the century last winter when a meteor exploded over his hometown of Chelyabinsk, Russia. From Greenbelt, Md., however, NASA’s Gorkavyi and colleagues witnessed a never-before-seen view of the atmospheric aftermath of the explosion.

Remote Sensing and Planetary Processes: An Interview with Dr. Alex Hayes
Dr. Alex Hayes is Assistant Professor of Astronomy at Cornell University. Hayes uses spacecraft-based remote sensing to study the properties of planetary surfaces, their interactions with the interior, and if present, atmosphere. Recently, he has focused on studying the coupling of surface, subsurface, and atmospheric processes on Titan and Mars.

As Curiosity’s wheels touch down, science gets rolling
As viewing parties celebrating the successful landing of the Mars Science Laboratory wound down early Monday morning, 400 scientists – many of them AGU members – were already using their newest tool for investigating the red planet.

Two Mars scientists prepare for Curiosity’s descent to the red planet
Two young AGU member-scientists balance nervousness with excitement over the imminent arrival of the Mars Science Laboratory, a.k.a. “Curiosity,” on the planet’s surface. For Ryan Anderson the journey beginning next week in Mars’ Gale Crater dates back several years when his graduate school advisor asked him, “Hey, you want to look at [Mars] landing sites? Here’s a cool one!” Building on other researchers’ previous studies, Anderson’s subsequent work at Cornell …

AGU interviews astronauts in space
AGU Video: On 19 June, AGU had the unique opportunity to interview three astronauts aboard the International Space Station about what it’s like to live in orbit and study the Earth from space. Astronauts Joe Acaba (NASA), André Kuipers (ESA) and Don Pettit (NASA) answered questions about their everyday lives in orbit, the hazards of life in space and how their experiences in microgravity have affected their thoughts about our home planet. Watch the video interview here!

Sadness, frustration, and ultimately admiration surround space shuttle Discovery’s welcome to Smithsonian
On Thursday, I went to the Udvar-Hazy Center to witness Discovery being rolled into the center’s space hangar. There, former U.S. Senator John Glenn, who became the oldest person in space when he launched aboard Discovery in 1998, gave a five-minute speech about the legacy of the space program, praising the ship behind him.
“Space shuttle Discovery is the star with the most extensive record of all the shuttle fleet,” he said, before expressing sadness that the shuttle program had ended, perhaps before its time. As he turned to sit, a man behind me in the audience said quietly, “Godspeed, John Glenn.”

Planetary Origins and Evolution: An Interview with David Stevenson
David Stevenson is the George Van Osdol Professor of Planetary Science at the California Institute of Technology. He researches internal structure and evolution of both major and terrestrial planets, application of fluid dynamics and magnetohydrodynamics [dynamicsof electrically conducting fluids] to planetary interiors, and the origin of the solar system. GeoSpace recently caught up with him to discuss his early career, his thoughts on the best way to send a probe to the Earth’s core, and his involvement with the upcoming Juno mission to Jupiter, among other topics.

A First for the Inner Frontier: Q&A with Sean Solomon on the MESSENGER mission
Sean C. Solomon, Principal Investigator for the MESSENGER mission and a former president of the American Geophysical Union, spoke with GeoSpace about the mission’s goals, Mercury’s potential to surprise, and his own path in research. He gave GeoSpace a sneak preview of topics he might be discussing during his talk at the annual meeting of the American Association for the Advancement of Science this Sunday in Washington, D.C.

Saturn’s moonlets play hide-and-seek
Everyone knows Saturn has rings. Lots of them. They’re big, easily visible, and have achieved iconic status.
But did you know that hiding within those rings are tiny, tiny moons, some less than a kilometer across?
The moons–or moonlets–are so small they’re invisible even to the Cassini spacecraft buzzing around Saturn. But we know they’re there: we can see the distinctive, propeller-shaped patterns they make in Saturn’s rings as they orbit the plane

What do you want to see on Mars? Tell HiRISE!
The most powerful camera ever sent to another planet wants to know what you’d like to see. HiRISE, dubbed “the people’s camera,” solicits public suggestions when deciding where to shoot. A team from the University of Arizona presented HiRISE, or the High Resolution Imaging Science Experiment, on Tuesday (ED23A-0712) with the only poster I’ve seen to pass out 3D glasses.
