Explanation

North Korea said its attempt to launch a new military reconnaissance satellite ended in failure on Monday when a newly developed rocket engine exploded in flight. The attempt came just hours after Pyongyang issued a warning that it would try to launch a satellite by June 4, in what would have been its second spy satellite in orbit. Instead, the launch became the nuclear-armed North’s latest failure, following two other fiery crashes last year. It successfully placed its first spy satellite in orbit in November.
