Weather No-go at the tanking decision

Astronaut · Who you talk to: The weather officer and the launch director

At the weather and tanking briefing, the forecast is outside the launch rules.

What this case adds

Decide "No-go" to begin tanking and explain the constraint.
Wait for the next decision point instead of loading propellant.

Critical fails

Answering "Go" with an open problem in your system.
Waiving a mandatory launch constraint after the terminal count has started: it cannot be waived.
Holding more than 3 minutes between T-6 and T-1:30 and pressing on instead of recycling to T-10.
Not knowing the abort or emergency procedure for your role.
