  • Satellites do have such restrictions. While you may expect the angle to be higher than for an aircraft, a satellite will not be directly overhead most of the earth. You’re still limited by angle and shadow, as well as time and frequency. Unless the target is high enough priority to reposition the satellite, it will be an oblique angle at a predictable time. While that angle will on average be higher than an aircraft, the aircraft can find different angles, at different times, with as much frequency as you like.

    Perhaps some things are more visible to an aircraft from the east than a satellite from the north, or perhaps the target has camouflage procedures at the known satellite schedule but an aircraft is more likely to catch them operating

    Don’t you check upcoming meetings? Such as at the beginning of the day?

    Once accepted, why would you care when any specific meeting is, just which ones are coming soon?

    Granted I track things requiring significant effort through other mechanisms, so my meeting prep is more typically checking statuses and collecting data/summaries








  • Nuclear was probably the best choice in the 1970’s; France made the best choice. But we’ve seen over and over again the problems are getting worse rather than better. Paperwork and process ever more unwieldy. Construction taking longer and longer. Radioactive waste building up with no permanent disposal. By far the highest cost power generation, and the difference is getting wider.

    Much of the posts about how great it will be this time is just astroturfing by those trying to profit. No, “small modular reactors”, didn’t solve the cost, construction, or process issues, but only raised the cost of generation. No, thorium isn’t the silver bullet and really doesn’t exist yet.
