Smell

Mr. David Aldrich has a space nose, his official NASA title and it is his role since 1974.

What does he do? It is to smell every object destined to be part of a mission and place it on a scale ranging from 0 to 4.

This work is truly fundamental because, in the event of unpleasant odors at space altitudes, astronauts certainly would not be able to open the windows due to external temperature and pressure. It is also true that the stench emanating in certain situations helps to understand the state of health of the components of the mission and this is why if an object exceeds 2.4 points it does not leave with the spacecraft.

To underline the importance of the tasks performed by David, NASA subjects him to a 10-smell test every four months to verify that his efficiency is still reliable. https://twitter.com/BrianRoemmele/status/1746691858783510689
