The NASA Kepler Space Telescope and the Dawn Asteroid Probe will soon be separated from the Earth.
Like Saturn's "Cbadini", there is no plan to put a brilliant end to the danger of launching a fuselage, but it is expected that contact with the planet will soon be cut off as the loaded fuel has already been controlled.
Kepler and Money have one thing in common: they set up a revolutionary "warrior" to broaden their understanding of the universe while launching into space and with different missions.
NASA does not know when the last contact will be with them, but they issued a press release before the next farewell.
The Kepler Space Telescope, launched in 2009, has been roaming the sun for nine years and has discovered more than 2,600 exotic planetary hunter planets. Kepler discovered 70% of the extraterrestrial planets discovered so far.
This made us understand that every star in our galaxy has at least one planet and that it opens to other worlds outside the solar system.
Kepler was charged with exceeding the expected lifespan in 2012, but the second gyroscope (the rotating star), which retains the space telescope's attitude the following year, has been out of order for some time and miraculously failed using solar pressure.
Since 2014, K2 has been given a new mission under the name "K2" and has carried out 19 missions to explore the extraterrestrial planet.
The 19th observation, which took place from August 29, took place in a difficult situation where the fuel could not be dropped. During a total observation period of 27 days, he explored more than 30,000 stars and galaxies in Aquarius. This area is home to dozens of planets and planets, including seven terrestrial planets with a celestial system & # 39; TRAPPIST-1 & # 39;
Kepler was able to transmit the observation data to Earth on November 19 with the help of the DSN on November 11, but it was confirmed that he had gone into hibernation for some unknown reason when the preparation of the next observation on the 19th.
Kepler does not have a fuel gauge, so we do not know how long it can last. Fortunately, even if you are awake from hibernation, you must perform the next observation mission or transfer the observed data to Earth forever.
The Space Telescope & # 39; TESS & # 39 ;, after Kepler, discovered 73 stars likely to have a planet a month after its launch in April, and two planets of similar size. And started operation seriously.
Don-Don, the first human-made asteroid probe, has been in use for 11 years since its launch on the Delta II medium-range rocket in September 2007, two years before Kepler.
In July 2011, I arrived at Vesta, the huge asteroid of the asteroid belt located between Mars and Jupiter, and I did a year orbit up to September of the following year, then to Ceres, the second planet on the planet. He has been exploring since 2015.
It was not the first time we orbited a celestial body in an asteroid belt, nor was it an exploratory activity that shifted the target from one to another. exploration.
The currency exploration mission was extended once after the completion of the theoretical life of 2016. In 2017, it was extended to lower the altitude to about 35 km and continue. the exploration of Ceres.
This confirms that Ceres can still be geologically active and that the seawater on the surface flows and the salt is formed on the surface.
Money also loses contact with the Earth when the fuel is exhausted. However, it is badumed that it will remain stable in the Ceres trajectory for decades after losing touch.
NASA will soon be saying goodbye to Don and Kepler, but with the data they send, new discoveries will be made in the coming decades.
