Different from other girls. Just loves good vibes. Easy going. Can be shy at times but once you get to know her she's a pretty funny person you'll want to be around. If you ever meet a Vivianna just know she's always real about everything. Fellas I wouldn't let a Vivianna go so easily. Once she's really about a certain guy you'll never second guess if she cares about you. So you'd be lucky, but for one thing ever mess with Vivianna the wrong way she the type to cut your d*** off.

The safeguarding of Earth and other worlds from biological cross-contamination (i.e. billionaires with too much time on their hands).

Also known as “planetary protection.” Planetary protection / quarantine “reflects both the unknown nature of the space environment and the desire of the scientific community to preserve the pristine nature of celestial bodies until they can be studied in detail.”

There are two types of interplanetary contamination. Forward contamination is the transfer of viable organisms from Earth to another celestial body. Back contamination is the transfer of extraterrestrial organisms, if such exist, back to the Earth's biosphere.

A derivative of Vivian and Anna, that combines the meanings of both and describes a girl that is awesome, lively, and beautiful. Very uncommon name, but that's because everyone wants it, even guys. Gives rise to a whole new generation of wannabes.
