Kepler space telescope is dead!!




NASA,s premier planet hunting space telescope is out of gas.
coming to an end of a 9.5 years mission,The kepler space telescope will no onger be able to search for planets orbiting other stars as announced by the officials in a news conference on october 30.

As officials quote "Because of fuel exhaustion,the Kepler spacecraft has reached the end of its service life."This line was said by Charlie Sobeck who is a project system engineer at NASA,s ames research center in Moffett field,Calif."While this is a sad event we are by no means unhappy with this remarkable machine."


The discoveries made by kepler has enormously changed the thinking of astronomers about other solar systems.Prior to the launch of Kepler in 2009 only 350 exoplanets were known to exist in the entire galaxy and all of them were known to be the size of jupiter or larger.
As of october 30,because of kepler the astronomers know more than 3800 exoplanets.

This spacecraft found planets in all shapes and configuration.
What,s more? Kepler,s exoplanet haul has been used by astronomers to predict that every one of the hundreds of billions of stars in the milky way should have atleast one planet on average and billions of those maybe friendly to contain life.

Kepler was also declared dead before once in 2013,the telescope lost the use of a second of its four reaction wheels which helped keep the telescope pointed steadily at the same patch of the sky.but somehow engineers used the power of sunlight to keep kepler alive.
But this time Kepler,s fuel pressure dropped by 75% in an hour before it shutdown.Before shutting down kepler transmitted all of it,s remaining data back to earth and there was not a drop of fuel left.

  "The Spacecraft will be left on its own to drift away in a safe and stable orbit around the sun"
