Seconds after launch, a privately owned, unmanned rocket contracted by NASA to deliver supplies to the International Space Station exploded. What went wrong? Science correspondent Miles O’Brien joins Judy Woodruff for an analysis of the accident and the privatization of the U.S. space program. Continue reading
It’s only a matter of time before a big comet or asteroid is on a collision course with Earth. Will scientists discover it, and be able to do something about it, ahead of time? Science correspondent Miles O’Brien talks to NASA astronomers who troll for trouble in the sky. Continue reading
India has joined the U.S., the former Soviet Union and the European Union as one of the elite few to successfully send a spacecraft to Mars, on its first try and for only $75 million — a fraction of the cost of other space missions. But there have been debates over whether the money could be better spent in a country where millions live in poverty. Hari Sreenivasan reports. Continue reading
India’s successful first mission to Mars is a major accomplishment for that nation, in both scientific and budgetary terms. To understand the historic feat, India’s space program and where it fits into the American exploration of Mars, science correspondent Miles O’Brien joins Hari Sreenivasan. Continue reading
A NASA spacecraft dedicated to measuring carbon dioxide in the atmosphere has achieved final orbit, producing its first science data this week.
A team of astronomers and students have discovered a stream of hydrogen gas in space that is the largest known to date — and dwarfs our own galaxy in comparison. Continue reading
Scientists have finally made lemonade out of the origins of our lemon-shaped moon. While the moon may look, to quote crooner Dean Martin, like a big pizza pie — the real shape is a bit more similar to a lemon. To explain, a study published in the journal Nature says, one needs to go back to when the satellite first formed. Continue reading
This spring scientists announced that they had found gravitational waves, the “smoking gun” evidence that the universe rapidly expanded in the trillionths of a second after the Big Bang. But new studies suggest that waves they found were just dust in the Milky Way galaxy. Continue reading
