Welcome to the Time-Traveller’s Academy. The Academy predicts important future events before each mission. These predictions help time travellers prepare for what will happen next. However, the prediction system has a problem – the sentences contain grammar errors. Your mission is to find mistake(s) and rewrite each sentence correctly. 
Do not forget to pay attention to the punctuation. You will get a point if you find all mistakes – there might be more than one. Write everything in full forms. Do not use contractions (I'll).
 
1. Until the security system recognises the code the travellers do not continue the journey.
 
2. If the equipment will not function correctly, the specialists do not start the procedure.
 
3. The time portal might opens during the full moon.
