NASA
NASA employs over 17,000 people.

It is also the first planet from the sun to have a natural satellite.
Silver
Silver does not react with clean air and water.
However, it becomes dull upon contact with ozone, hydrogen sulfide, and air polluted with sulfur compounds. Silver halides slowly decompose when exposed to light.

The surface temperature of the moon is 75 K.
Large Magellanic Cloud

Graphene
Although graphene consists of an element that is abundant on Earth, its production costs are high.
This is a major obstacle to graphene finding mass application in many fields. For now, only small amounts are produced.
Ganymede
Probably in 365 BC, the Chinese astronomer Gan De managed to observe Ganymede with the naked eye.
