A strange "UFO phenomenon" occurs in SpaceX's Falcon 9 rocket launch, and why?

Local time in 2017 December 22 (Friday), California SpaceX Falcon 9 rocket that was launched from Vandenberg Air Force Base on the night of, in the night sky a strange pattern to like think the missile test-firing of a UFO or a certain country It became a topic with what I drew. In addition to that is the whole story movie that were taken are contained the pattern of an exceptionally rare phenomenon, while others are housed and also clearly sight of the Falcon 9 rocket unique that you can return themselves to the ground, and a must-see content like rocket It is getting.

Here's a Time-Lapse of SpaceX's 'UFO' Rocket Launch

The Falcon 9 rocket launched by SpaceX was launched with 10 Communication Satellites of Iridium Communications and drew a dazzling bright pattern in the sky of California that was about to come at night. Earlon Mask CEO also understands the situation, he is skipping a joke with "Nuclear Alien UFO from North Korea" with his own Twitter account.

The topic in this launch was the pattern of the locus that the rocket made. In the following time lapse movie which photographs that state at a low speed, the appearance that the pattern changes is beautifully captured.

The trajectory of the Falcon 9 rocket shining white in the sky of California trying to be from evening to night. This movie was filmed by Jesse Watson, a photographer living in Arizona state, taking full advantage of four cameras and five lenses.

In the movie you can see the state of the Falcon 9 rocket flying to the side of the horizon, leaving something like white smoke spreading widely.

Mr. Watson succeeded in getting rare opportunities rarely found. The scene feeling that the white pattern floating in the sky changes slowly with time is captured.

By the way, the type of camera used by Watson was "Nikon D 810 (× 2 units)" "Sony a 6500" "Sony a 7 S II", the lens used was "Nikon 14-24 mm f / 2.8" "Nikon 24 - 70 mm f / 2.8 "" Nikon 85 mm f / 1.8 "" Nikon 25 mm f / 2.2 "" Tamron 150 - 600 mm f / 5-6.3 ".

The reason that the trajectory clearly emerged in the night sky is that the weather situation at that time and the time zone are greatly related. The airspace where the rocket flew was at that time a layer of very cool and dry air, and there was a gas contained in the gas discharged from the rocket engine of Falcon 9waterThe release of ice creates small ice particles. Also at the altitude where the rocket was flying, the sun did not sink yet and the sun was reaching, while I was about to get to the night near the surface. By overlapping these conditions, it was a California sky trying to be at night, receiving light from sunlight as water or ice particles spewed from the rocket, shining brightly and surprised the people. And say the trajectory of the rocket, but there is a image of a straight line in the same way as contrail, the current trajectory drew a strange pattern is, due to the low atmospheric pressure and high altitude, the gas that has been ejected from the rocket nozzle It is considered as one of the reasons that it expanded greatly.

The other is the unique reason of the Falcon 9 rocket that the general public can see in the movies successfully filmed thanks to unusual weather conditions.

Launched Falcon 9 rocket. It continues to rise while releasing a bright light.

Approximately 2 minutes and 30 seconds after launch, the Falcon 9 rocket which accelerated to about 7500 km per hour cuts off the first stage booster, then ignites the second stage rocket and aims at outer space.

Then, the turbulence in the shape of the gas blown out from the second stage rocket is great.

This was because the first stage rocket which finished its role injected gas to change direction. That is why it was "disturbance" because of Falcon 9 which reuses the first stage rocket. In the movie, the state of the 2nd stage rocket (lower left figure) that continues to rise towards the universe and the state of the 1st stage rocket (right) to change direction to aim at the landing point are contained in a glimpse.

In this launch, the first stage rocket was not collected, it seems that it fell to the planned place. The movie contains a state of the first stage rocket aiming at the falling point while blowing gas from the attitude control thruster.
