If you are looking for short period events, losing a single frame can mean losing critical data. > Or they can just use that information for better scheduling: wait a minute or two to image a particular spot, so there won't be satellites in the field of view. Which means more time and effort, and ultimately money needs to be spent on scheduling observations to avoid the thousands of these satellites. And sometimes it isn't an option. What if a GRB happens in the same field of view as one of these satellites and you want to observe it as soon as possible? Now there are some types of observations that won't be impacted that much. If you can tolerate scheduling around it, or throwing away some of your frames it is just a minor annoyance. But a lot of observations are also more sensitive to such disruptions.
