Arianespace's population is 292.

Arianespace was created in 1980.

Arianespace is the company in charge of the space project 'Ariane' a French-built space satellit launcher. Ariane is the modern French spelling for Ariadne, a mythologic female character who helped Theseus, giving him a sword and a ball of thread, so that he could find his way out of the Minotaur's labyrinth. She also has a constellation named after her character.

Some work for NASA or the Air Force; many work for universities. A few work for private companies like Virgin Galactic, Scaled Composites, Bigelow Aerospace, ArianeSpace or Space-X.

There is no field of "alien research", because as yet there is nothing to study; i.e., no aliens are known to exist. You might go into exobiology, but this seems inconsistent with a degree in aero engineering.

I would recommend going to work for Rocketdyne, General Dynamics, McDonnell Douglas, Aerojet General or Morton Thiokol. Outside the United States, Arianespace might be a good option.
