When the Mars Curiosity made its dramatic and first-of-its-kind landing on Mars in August of 2012, the hope was that the $2.5-billion rover could confirm what scientists had suspected: that there was life on Mars.
Today, in a paper released in the journal Science, researchers explain that if the Red Planet is harboring life, the instruments on the rover have been unable to sniff it out.

For several weeks now, two unmanned spy planes have been flying over the Atlantic on an unusual mission: gathering intelligence about tropical storms and hurricanes.
The two Global Hawk drones are a central part of NASA's five-year HS3 (Hurricane and Severe Storm Sentinel) Mission investigating why certain weather patterns become hurricanes, and why some hurricanes grow into monster storms.
NASA's two Voyager spacecraft, launched in 1977, have made history in a dramatic fashion by exploring the outer planets: Jupiter, Saturn, Uranus and Neptune. Now one of the vehicles, Voyager I, has made another pioneering leap. It is the first spacecraft to leave the vast bubble of hot gas that surrounds our solar system.
At long last, Voyager 1 is now in interstellar space.
