Re: Into the Vast
Phelar has the ability of Machine Telepathy--that is, she can communicate telepathically with a computer, as if the computer had an actual mind.
In this instant, she's pushed that telepathy by interfacing the ship's computer with the communications system... not a big stretch as the two are usually linked anyway. She was then able to project her telepathy to the Gnome ship's computer via the communication link, and was able to do a sort of reverse Machine Telepathy with the Gnomes... or at least one of them.
However, she wasn't able to use her computer link to use the internal scanners to find out how many Gnomes were on board... because the sensors were turned off.
Communications didn't require as much power as the sensors, so they've probably been shut off to conserve power.
===================================================================================
On board the Starhawk, Revonoss begins scanning for the missing Gnome supply ship. He doesn't find any sign of it at first... not out to the range of the ship's sensors.
Sensors detect energy. If they detect any mass, it's because of the energy the mass inherently has, such as being a source of gravity. Typical sensors scan for radio waves first, as that is what communications use. Then they scan for other types of energy... gravity, light, neutrinos, etc. In general, sensors fall into two types: passive and active. Passive sensors just sit there and register any energy that impacts them. Thus, in a silent running scenario, they still register any energy that's out there.
Active sensors actually send out an energy of their own. Sonar, radar and lidar are typical active sensors, emitting sound, radio and laser/light energy respectively, and then registering anything that bounces back.
Naturally, some forms of sensors have a greater range than others. Sonar, of course, only works in an atmosphere or underwater.
So, Revonoss runs through the gamut of the Starhawk's sensors, passive and active, and finds nothing showing up out to the maximum range. This isn't surprising, when he thinks about it... if the supply ship didn't show up, there can be two probable reasons for that: it got lost (meaning it can't find the mining ship--not all that surprising in the Drift) or it's damaged and can't get here.
Technically, of course, there could be a few other reasons, such as it was never coming in the first place, but those reasons aren't anything the Starhawk can do anything about... or even determine.
Thus, if the ship is lost in the Drift, it's far enough away that Revonoss can't find it with the sensors. That means the ship would have to fly around in the Drift in a typical search pattern and hope it finds the supply ship.
Also, sensors can Detect Magic, but since magic doesn't work in the Drift, those sensors are useless as well.
After putting the primary sensors through their paces, Revonoss comes up empty. The supply ship isn't anywhere within range. Well, that is, a functioning supply ship isn't within range.
He has to tweak the sensors a bit to start looking for a damaged ship. If it's really damaged, it'd probably be useless as a supply ship any more, meaning that it can't get to the mining ship on its own any more.
It's only when he adjusts the sensors for that possibility that he picks up... something--a weak neutrino (fancy word for a type of energy) emission. There is no known plane outside the Prime Material Plane that has natural neutrino emissions. That includes the Drift. Since the 'stuff' in the Drift comes from other planes, there would be no naturally occurring source of neutrinos, because there are only two known sources of neutrino emissions: stars and power cores. It's the primary way you detect another ship, other than visually.
After taking several readings and making adjustments, Revonoss determines that the neutrino emission is coming from within the 'planet' (the slab of rock that they are landed on). After thinking about that, and doing a bit more tweaking of the sensors, he revises his analysis: not within the planet, but on the other side of the planet--in that mountainous terrain.
No stars in the Drift, so that should mean it's a power core of a ship that's emitting the neutrinos. There's always the possibility (absurd as it might be) that it's some sort of aberrational creature of the Drift that's emitting them.
