A £255million satellite that will monitor the Earth's atmosphere has successfully launched into space.
But conspiracy theorists believe something overshadowed the 'perfect' launch on Kyushu Island in Japan.
They claim an unknown 'mysterious craft' passed closely by the rocket as it travelled at 25,000mph - and some think it could be aliens monitoring our technological advances.
Thousands of people gathered to watch Japanese Space agency Jaxa launch its Epsilon 3 rocket at 6.06am on January 18.
Video shows that shortly after the craft engaged its secondary boosters a UFO , allegedly flying at the same altitude as the rocket, appeared.
The object was made up of three white lights and a red blinking beacon that appear to swoop close to the rocket.
