OTD…March 6 and Kepler

A United Launch Alliance Delta 2 rocket fired away from a California military base and disappeared into an overcast cloud deck Saturday on its final flight, carrying a NASA research satellite into orbit and closing the book on a nearly 30-year legacy of launches.

After downloading science data and bypassing a balky thruster, NASA’s Kepler mission has resumed its search for planets around other stars after a two-month pause in observations, but engineers expect the spacecraft to soon run out of fuel.

A United Launch Alliance Delta 2 rocket lifted off Saturday from Vandenberg Air Force Base in California with the JPSS 1 weather satellite, the first in a new line of polar-orbiting observatories for NOAA.
