“This is not the outcome we were working toward, but it does not change why this mission was worth attempting," NASA Administrator Jared Isaacman said in a statement.
The unmanned sky observatory «Swift» had mainly investigated so-called gamma flashes in space. Soon it could crash, a rescue operation by the U.S. Space Agency remained unsuccessful.
NASA and a space launcher have declared the rescue mission for the Swift space telescope failed. The research satellite will probably enter and burn into the Earth's atmosphere this year.
