A job done in a particularly horrible manner... Like if the door is cracked in half, someone just duct tapes it. Or it could mean something that is put together cheaply and with no effort. Like if you need the fence post to stay in place, for good, you lodge a toy truck into it... Basically anything fixed without the necessary tools and will fall apart with the next 24 hrs.

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.
