At Owen's explanation, Steve makes a point of mapping out the night sky when he can get a chance. Satellites may or may not be possible to see, but being a sailor he's got a good foundation of what stars they would see depending on location. If he can identify the right stars, the might be able to say where they are.

"Not necessarily. Unless someone is scrutinizing the area for whatever reason, that there is activity here where there wasn't before wouldn't be enough to set off any alarms. What kind of technology is available to us here? We could try to signal one." Then he realizes someone may have already done what he was previously thinking. No need to recreate the wheel and if it was done at a different time of year the view would have changed, that would give him more information to work with. "Has anyone mapped the stars?"
