What is the desired outcome and why in space?

The desired outcome is a demonstration that entanglement can persist at very large distances. In space, because at Earth there are disturbances which tend to destroy the entanglement.

 

[DrClaude]

Desired outcome: completely secure communications with detection of eavesdropping.

Why in space? Because that is where communication satellites are.
