Hi, you’re not doing anything wrong, this is a known glitch I haven’t been able to solve! The work-around is not a great solution but if you stop the camera from spinning by moving it manually (CTRL+arrows) and point it a bit closer to where you’re trying to target (at the start of the first mission the asteroid is left of earth, between the earth and sun), try targeting again and it should work. Hopefully one day I will figure out this bug!
i guess i have another question, the coordinates are in (h,v) both being from +90 to -90, so in the second event, by this coordinate system, there is no -158.55, unless you use the +90 as a replacement for 0, in which case, why not just use -68.55? it's pretty confusing (also i keep getting scared that i'll miss the event, since where im at they dont give a date)
Vertically the view is limited to +-90 to prevent flipping upside down, but horizontally you should be able to spin entirely around with coordinates between 180 and -180, where negative H is left of Earth, positive is right, and looking at coordinates 0x0 is the middle of Earth. So -158.55 is that many degrees left from Earth.
By the way, you can pause the game speed while you look around if the collision is occurring too soon. I believe the only station function not possible while paused is firing the laser.
