An Unidentified Spaceship Cruises Past Outpost 11 , a Space $\frac{3}{5}$

True/False

An unidentified spaceship cruises past Outpost 11 , a space station floating in deep space, at a speed of $\frac{3}{5}$ , without acknowledging requests for identification. Ten seconds after the ship passes (according to Outpost 11 clocks), Outpost 11 sends a message to the departing ship, warning that it will commence firing if the ship does not respond. Fifteen seconds after that, Outpost 11 sensors indicate that the ship has raised its shields. This is clearly a response to the warning.
