Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - Curiosity is the closest thing yet to a real geologist being sent to Mars. As the rover prepares for its dramatic landing, scientists on Earth are preparing for the incredible amount of data that Curiosity will return from Gale Crater. See article.
g Life - When Daniel Glavin isn't designing a chemistry experiment to run from millions of miles away, he's a researcher in the Astrobiology Analytical Laboratory at NASA's Goddard Space Flight Center in Greenbelt, Maryland, where scientists are working to solve two of the biggest mysteries facing humanity: How did we get here? And are we alone? The answers may lie in carbonaceous meteorites. See article.
g Cosmicus - Curiosity has successfully touched down on Mars. Several minutes later, amidst the cheers and high-fives at the Jet Propulsion Laboratories, the rover’s first image was received on Earth. See article.

The Drake Equation
This formula estimates the number of intelligent civilizations in our galaxy.N=(R*)(Ns)(Fp)(Ne)(Fl)(Fi)(Fc)(L)
Where:- N = Number of civilizations we can communicate with
- R* = Average star formation rate
- Ns = Percentage of stars capable of supporting earth-like planets
- Fp = Percentage of those stars with planets
- Ne = Average umber of planets in those stars' habitable zones
- Fl = Percentage of those planets where life begins
- Fi = Percentage of planets with life where an intelligent species evolves
- Fc = Percentage of those intelligent species that develop communication technology
- L = Average lifetime, in years, of a civilization that develops such technology
