Orbita: Look for the satellites that bounce back a lot of infrared light – that’s usually water vapor. Track their low‑orbit passes, pick out the ones that linger over valleys or riverbeds, and use a simple spectral filter on your phone to flag bright patches. If you can line up two passes a few hours apart, the shift in the infrared signature tells you if the source is moving or drying out. Basically, find the warm spots that stay warm, and that’s your best bet for a quick water spot.

Sounds like a plan. Just keep an eye on the satellite’s altitude—sometimes those low‑orbiters give a false warm read if they’re passing over a hot rock instead of water. If you spot a consistent, cool‑bright patch that shows up in consecutive passes, that’s probably your oasis. Good luck, and stay hydrated.
