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
In space, green beans taste like grass and sliced strawberries are repulsively sweet. That’s according to NASA astronaut Douglas Wheelock, who spent more than 178 days living — and eating — aboard the International Space Station and space shuttle Discovery. Continue reading
Astronomers have discovered a cluster of several thousand stars that was ejected out of a distant galaxy at a stellar speed of more than two million miles per hour. The group of “runaway stars,” named HVGC-1 for “hypervelocity globular cluster,” was found by Nelson Caldwell and his team at the Harvard-Smithsonian Center for Astrophysics after they found the bright sphere traveling at a high velocity from the the elliptical galaxy Messier 87.

Online voters can select one of three designs that will be used as a cover to protect the spacesuit from abrasions while astronauts train in multiple vacuum chamber tests and at a rocky Martian surface analog site at the Johnson Space Center. Ultimately, these tests will guide NASA in designing their next spacesuit. Continue reading
