Direct the operations of a planetarium.

I need the weekly staff rota and show rundown finished for Friday’s public dome program. Read the attached draft, confirm the presenter and technician names match the bookings ledger, make the blackout and projector checks explicit, and prepare a one-page operating cue sheet for the evening shift to sign off on before doors open.

Before I send this to the dome crew, make the schedule simple to scan—put show start, presenter, and technician in the top row, flag any overlap or missing roles in red, and extract a one-sentence risk note for each show (projector warm-up, laser alignment, seating limits) so the lead can approve quickly.

We just lost the technician for Friday’s 7pm public dome show. Presenter is confirmed, volunteers are listed but untrained, and ticket sales are high. I’m worried about safety checks and projector alignment slipping, but I don’t know who on staff can do that work reliably tonight. Who should I call first and what immediate compromises keep the show safe without canceling?

Across the past six months we repeatedly scramble for technician cover the morning of public shows, which costs time and risks last-minute cancellations. I want one habit that prevents that—what scheduling, cross-training, or rostering change would be simplest to enforce and most likely to stop this pattern starting now?
