Europe and Japan's BepiColombo spacecraft, which launched in 2018, will fly by Earth on 10 April and use our planet's gravity to swing towards the inner solar system. Learn more about this mission and why we study Mercury.
The Planetary Society is celebrating the 50th anniversary of Apollo 13, which launched on 11 April 1970. Disaster struck on 13 April, prompting the crew's infamous "Houston, we've had a problem" call for help. Learn what happened, and how NASA got the astronauts home safely on 17 April.
Apollo 13 was the 3rd attempt to land humans on the Moon and the 1st to fail. Fifty-six hours into the mission, an explosion forced the crew to abort their Moon landing and take shelter in the Lunar Module. The crew ultimately returned to Earth safely.
I'm leaving shortly for Nantes, France to attend the 2011 joint meeting of the Division of Planetary Sciences (DPS) of the American Astronomical Society and the European Planetary Science Congress (EPSC). You may be saying, wait, why is the American Astronomical Society having a meeting in France?
If you are reading this and happen to recall an entry that struck you as particularly educational or having a particularly beautiful picture or whatever, I'd very much appreciate it if you could note that in the comments (or by email or Twitter, if you prefer).
I spent much of the past week attending the Caltech Space Challenge, a student-organized international competition to design a human mission to a Near-Earth asteroid. It was a great week, and one of the most positive, upbeat and hopeful programs I have participated in concerning the future of space exploration.
The summer heat is starting to cool off and the swarms of mosquitoes are nearly survivable without heavy artillery. For some backyard astronomers, fall offers cool nights and comfortable weather to enjoy the stars by.
GRAIL is trying for launch today at 8:29 PDT / 12:29 UT or 9:08 PDT / 6:08 UT., and here I am at 5:00 am my time ready to watch. As before, I'm watching the feed through Spaceflight Now's GRAIL mission status center.
The twin spacecraft of the GRAIL lunar gravity mission are set to launch side-by-side on a Delta II rocket on Thursday, September 8. Here's all the places where you can find information about the upcoming launch.
I just got the following email from the American Geophysical Union (AGU), requesting anyone whose Congressperson sits on the Appropriations Committee to place a phone call to support the production of Plutonium-238, the isotope of plutonium that powers spacecraft that cannot run on solar power.
