rubbing ones nose, getting faster and faster, until you sneeze

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 nose orgasm is when a person sneezes. If you sneeze, it is considered to have a nose orgasm. A sick person may have multiple nose orgasms in a day. A person with llergies may also, have multiple nose orgasms in a day. There are medications to help prevent nose orgasms during nose orgasms.
Usually, when someone is having a nose orgasm, it is when the nerve endings of the mucus membranes of the nose are irritated, due to the swelling of the membrane, for example, when a foreign object such as a gnat invades our nose, when we have a cold or when flu or allergy season arises.
