NASA sent the Kepler telescope to the waiting state before August 2 this year, when probably the last communication session will take place and the device will send the actual data to Earth. On account of this telescope, about 70% of the 3,750 exoplanets discovered make Kepler the most effective mission.
In early August, Kepler wakes up and receives a command to adjust the position to send data using the main antenna. As Space writes , if after the completion of this mission the fuel remains in the telescope’s tanks, he will proceed to the next. However, it will be completed, it is not known, and it is impossible to refuel the device: it is in solar orbit.
Kepler’s mission started in 2009. In the spring of 2018, a replacement for the telescope – Transiting Exoplanet Survey Satellite (TESS) – was sent into space. The coverage of the TESS is approximately 400 times greater than that of its predecessor.
