When preparing a satellite for launch, the engineers use big red tags to mark components that must be removed before the satellite is encapsulated in the rocket fairing and launched. The idea is to remove these components as late as possible in the launch campaign, and the red tags serve as an important reminder do so.

These items are usually covers that protect things like optics, connectors and so on. Very careful attention is paid to removing these items because if one is forgotten, the satellite will not work properly and there’s a good chance that the mission will be lost.
ESA’s Gilles Labruyère, who is currently working on the Aeolus campaign in Kourou, said, “There are stories of satellites being lost because an antenna or a solar array couldn’t deploy.
“To make sure nothing is forgotten, all of the items are listed and get checked off on removal. We also have cases with holes that are the same shape of every red tag. If a hole remains unfilled, liftoff is prohibited.”
