NASA Kepler Planet-Hunting Space Telescope Wakes Up Again







		The Kepler alarm clock whipsaw continues.

		From NASA Kepler space telescope, which has discovered more than 2,650 alien planets to date, emerged from another dream on Thursday (October 11), agency officials said.

		Kepler has been without fuel for a long time. Then, the members of the mission team have put the spacecraft to sleep. repeatedly in recent months, in an effort to ensure that Kepler has enough fuel to orient itself to Earth and transmit its latest batches of data home.

		Such relays are only possible during certain windows. Kepler's team relies on NASA's. Deep space network to capture incoming data and you must share this system of large radio antennas with other missions of the agency. 

		The $ 600 million Kepler mission was launched in March 2009. Initially, the spacecraft observed more than 150,000 stars simultaneously, observing small drops in brightness that could indicate the passage of planets in orbit through the faces of these stars.

		In May 2013, the second of the four reaction wheels to maintain Kepler's orientation failed, which ended the observatory's original mission. But Kepler's manipulators discovered a way to stabilize the ship using the remaining wheels and the pressure of sunlight, and Kepler soon embarked on an extended mission called K2.

		During K2, Kepler has been looking for exoplanets and observing a variety of other objects and phenomena, during the course of the 80-day campaigns. Kepler began collecting data for the last, Campaign 19, on August 29. But the mission team put the observatory to sleep less than a month after realizing that Kepler's targeting abilities had degraded.

		"We are still monitoring the health of the ship as we work to download data from Campaign 19," NASA officials said. wrote in an update Today (October 12).

		Replenishing Kepler is not an option. The observatory, which is responsible for approximately 70 percent of all exoplanet discoveries to date, orbits the Sun and is millions of miles from Earth.
