Mars Rover
You certainly didn't hear it here first: today NASA, at a press briefing, announced that minerals analyzed by the Curiosity rover indicate that life might, in the galactic past, have survived on Mars. The rover's been poking around an ancient network of stream channels descending from the rim of Gale crater since September of last year; now, after drilling into the sedimentary bedrock nearby, it's hit on a treasure trove of life-supporting minerals: carbon, oxygen, hydrogen, phosphorus, sulfur, and nitrogen. These mineral findings are really just icing on the cake, as the geological clues–…
The Mars Science Laboratory Mission has piles of cool equipment on board Curiosity Rover, which is closing in on Mars as we speak. The landing is expected to be next Sunday/Monday, 10:31 p.m. Aug. 5 PDT (1:31 a.m. Aug. 6 EDT, 05:31 Aug. 6 Universal Time) plus or minus a minute.. But not really, because the event is happening a it far away in spacetime; those are the times that the signals from Mars will arrive on the planet Earth, about 13.8 minutes after the event has happened. The mission is expected to last one Martian year, which is close to two Earth years. The weather at the landing…

The final mission of Space Shuttle Atlantis has spawned a whole series of perspective pieces on the history, state, and future of space exploration. Some, like the YouTube video "NASA's increase of awesome to continue," are unabashedly exuberant celebrations of the future in store for us in space; others, like this thoughtful piece in Technology Review entitled "Was the Space Shuttle a Mistake?," are depressingly and effectively critical of the cost both in dollars (more…

Rosalba, what first sparked your interest in science?
I've always had big dreams -- even as a young girl. As soon as I started to walk, I took an interest in conducting experiments with whatever was available around such as household plants and various chemical compounds. I'm lucky I didn't end up poisoned or otherwise hurt! I remember dismantling alarm clocks. I was so curious!
As a young girl, I was in poor health and as a result spent a lot of…
