...WAIT UNTIL JANUARY? The shuttle impedes the station's movement when attached. At certain points in the year, this makes it difficult to capture solar energy or maintain temperature, factors NASA considers for launch timing...
Applications of the laser chip may radiate into environmental sciences, as it will soon monitor the changing concentrations of greenhouse gas emissions, Capasso said. He, along with atmospheric chemistry professor James G. Anderson, plans to collaborate with NASA to send lasers into the stratosphere to study the effects of global warming...
...their light dims in a repeating pattern. If it does, he won't have long to wait: a habitable M-dwarf planet would have a "year" only three or four days long, so transits would happen all the time. Things will get even easier in 2009, when NASA launches a satellite called Kepler. Soaring above our planet's murky atmosphere, it could spot Earthlike planets transiting across the faces of stars by the dozen...
