Super-Rover Will Search for Life on Mars
N.A.S.A.'s latest Mars rover will launch later this month. The size of an S.U.V. and powered by decaying plutonium, it will search for water and past signs of life beneath the martian soil.
What's the Latest Development?
On 25 November, N.A.S.A. will launch Curiosity, the largest and most complex robotic vehicle ever meant to explore Mars. Due to its size, nearly that of an S.U.V., engineering solutions had to be found to land the vehicle. Whereas past rovers were light enough to hit the ground covered in airbags, Curiosity will be airlifted to its landing spot by a 'skycrane'. Once on the Martian soil, the vehicle will look for hilly terrain where evidence of past water flows and biological compounds might be found.
What's the Big Idea?
While past rovers were limited to identifying soil chemicals by examing the light reflected off the planet's surface, Curiosity will carry an entire chemistry lab on its back, complete with drill to bore through rocks. Soil samples will be sent through a series of chemicals which will determine constituent compounds with an eye toward finding organic molecules. Modifications made to the vehicle's landing technology, if successful, will prepare the way for launching still heavier vehicles, ones which can transport soil back to Earth.

Orangutans join humans and bees in a very exclusive club
- Orangutan mothers wait to sound a danger alarm to avoid tipping off predators to their location
- It took a couple of researchers crawling around the Sumatran jungle to discover the phenomenon
- This ability may come from a common ancestor
In a breakthrough for nuclear fusion research, scientists at China's Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.
- The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
- Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
- Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.
