    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.

    Desired outcome: completely secure communications with detection of eavesdropping.

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