Esther throws the laptop into the water just before it is destroyed by the defense satellite's laser beam.

This was a program to improve the database on nuclear hardening design techniques for defense satellites.

After turning on his computer, he suddenly acquires information that the strategic defense satellite "Colosseum" has picked up some nuclear weapons being fired.

A discovery in gamma-ray astronomy came in the late 1960s and early 1970s from a constellation of military defense satellites.
