In July, I joined a team from Johnson Space Center and elsewhere in investigating the geology of Apollo Valley with rover-deployed scientific instruments. Apollo Valley is a former 1960s Apollo-era astronaut training site at 3,505 meters (11,500 feet) on Mauna Kea, Hawaii. The project was funded by NASA's Moon and Mars Analog Mission Activities Program, which funds projects that simulate scientific, robotic, and human aspects of exploring the Moon and Mars, with the goal of designing the most effective, efficient, and well-integrated future missions. 

I first heard the sad news while having a late lunch with friends at a seafood restaurant on the water in Annapolis, Maryland.

Astronomy enthusiasts around the world are gearing up for Tuesday’s celestial show: the transit of Venus across the face of the Sun.  The small black dot of Venus, silhouetted against the bright Sun, will be visible with safe solar telescopes and, to those with especially good vision, with the naked eye when protected by eclipse glasses.

What's inside a planet? What instruments do scientists use to figure it out? And what clues does a planet's surface give us? On Saturday, April 21, Lisa Walsh and I, scientists from the Museum's Center for Earth and Planetary Studies, invited visitors to the National Air and Space Museum's Explore the Universe Family Day to think about these questions, through two hands-on activities relating to our research into tectonics on Mercury.

Having grown up less than 90 minutes away from the famous Cedar Point amusement park in Sandusky, Ohio, I got the chance at least a few times each summer to see an IMAX movie. I remember the packed seats for the pre-show, everyone clamoring for the best seats right in the middle, but everyone was usually just happy to be escaping the heat for the air conditioned theater. When The Dream Is Alive was released in June 1985, I was just old enough to ride those massive roller coasters, but seeing IMAX films at Cedar Point really left an impression on me: a big impression. Seeing those sweeping views of Earth and space on a gigantic screen made spaceflight seem so real, and utterly amazing.

If all goes according to plan, on November 25th the Mars Science Laboratory (MSL) rover Curiosity will leave the Earth and begin its journey to Mars. Any delays due to weather or other factors should be accommodated by a launch window that extends until December 18th. The spacecraft will use a new landing system to arrive at its landing site on Mars in August, 2012, and the rover carries an impressive array of scientific instruments.

The remarkable twin Voyager spacecraft continue to explore the outer reaches of the solar system decades after they completed their surveys of the Outer Planets. 

I was thrilled to be a part of the NASA Tweetup for STS-135 July 7 and 8 at Kennedy Space Center. It was exciting — and almost surreal — to be there for the end of the space program that my generation grew up with. We weren’t around for the Moon landings, but we all remember the first time the space shuttle “took off like a rocket and landed like a plane.”

The Perseids are coming!  The most consistently best meteor shower of the year, the “Perseids,” (PER-see-ids) will reach their peak next week.

Since Howard McCurdy and I co-authored Robots in Space: Technology, Evolution, and Interplanetary Travel (Johns Hopkins University Press, 2008), I have been interested in the possible merger of humans and robots into a single entity to undertake space exploration.
