OOC:
@Brahim, you can give me a Technology roll for your research into bauxite and salt mining tech.
Also, we'll assume that Riya informs you about the mystery ship. Unless the captain explicitly tells her to keep quiet, Riya sees no reason not to inform everyone about it. Also, she likes to gossip.
As far as the relay satellite idea, that is definitely feasible. You could modify a sensor buoy and launch it from the countermeasure dispenser. Normally, the dispenser buoys are intended for distracting missiles, but it wouldn't be too difficult to attach extra sensors to one of them in order to extend the Riyad's sensor range.
As far as information about the Kalites, you find the same information that Sa'id was given by Riya. Very little about their biology. Because the Riyad doesn't have a Library Database feature, her data on certain topics is fairly limited.
[ +- ] Kalites
"My database doesn't have much about the Kalites. According to the archives of the Colonial Agency, the Kalites are a very insular culture, even for a nomad tribe. They are apparently known for being xenophobic, but given that they're humanites, most settlers on Jina are happy to leave them alone. They live in communities in the surrounding mesas and gorges around Aram's Ravine. It seems that they were already living on Jina when Aram Bakkal founded the settlement. No one knows when the Kalites first settled the planet. There are records of some conflicts between the Kalites and reckless trivium prospectors, but nothing more."
