There's a small spacecraft called Messenger that's been orbiting the planet Mercury for a year. Today, at the Lunar and Planetary Science Conference in Houston, astronomers revealed what they've learned about the innermost planet in our solar system, and some of the new knowledge is puzzling.
Maria Zuber, a planetary scientist at the Massachusetts Institute of Technology, studied a large crater 900 miles across called Caloris.
Every so often, pieces of heaven crash into Earth.
They can come from our own solar system, or millions of light years away. Few of us are lucky enough to get our hands on one of these space rocks. But for meteorite hunters and dealers such as Ruben Garcia, touching a piece of outer space is a daily routine.
The Best Hunting Grounds
One of Garcia's favorite spots to go meteorite hunting is an enormous dry lake bed in southern Arizona.
After decades of global dominance, America's space shuttle program ended last summer while countries like Russia, China and India continue to advance their programs. But astrophysicist Neil deGrasse Tyson, author of the new book Space Chronicles: Facing the Ultimate Frontier, says America's space program is at a critical moment. He thinks it's time for America to invest heavily in space exploration and research.
Ask people who know John Herman of Newmarket and they’ll tell you he keeps really busy –plays, meetups, video blogs, improv comedy, music… He’s basically everywhere at once, but there’s one place even John Herman hasn’t gone (yet): space.
That may change, as John is one of 20 semifinalists in the Space Race 2012 contest; the winner goes into sub-orbital flight on a trip with a commercial spaceflight company.
Every 10 years, about two dozen of this country's top astronomers and astrophysicists get together under the auspices of the National Research Council and make a wish list. The list has on it the new telescopes these astronomers would most like to see built. At the last gathering, they said, in essence, "We most want the Large Synoptic Survey Telescope."
Here's why. A synoptic survey is a comprehensive map of every square inch of the night sky. The Large Synoptic Survey — LSST — will do that multiple times.
Roger Boisjoly was a booster rocket engineer at NASA contractor Morton Thiokol in Utah in January, 1986, when he and four colleagues became embroiled in the fatal decision to launch the Space Shuttle Challenger.
Boisjoly was also one of two confidential sources quoted by NPR three weeks later in the first detailed report about the Challenger launch decision, and the stiff resistance by Boisjoly and other Thiokol engineers.
The latest twist in the Obama administration’s so-called Asian pivot. The president’s chief science advisor, John Holdren, has said the US would benefit from cooperating with China on future space missions. But federal legislation now prohibits NASA from pursuing such efforts with a little known clause that’s popped up in two pieces of legislation within the past year.
Space! The final frontier, an immense void populated by our imaginations and as far as we know, not much else. Since the NASA shuttle program topped headlines for one last nostalgic time this summer, there have been few newsworthy developments in space exploration… until now. Here to share some big news is freelance science journalist Lee Billings, who’s working on a book about the inter-galactic search for earth-like planets.
