The fundamental launch pre-heating preparations were already completed, but the tasks in the control center weren't over yet.
"Now is not the best time for the launch. According to our advanced forecast of the launch window and weather conditions, a stable and normal satellite rocket launch can be carried out in about 16 minutes and 50 seconds from now."
The staff in the control center also made multiple preparations, including pre-calculating the orbital parameters, checking weather conditions, and launch confirmation.
Once the conditions were confirmed to meet the requirements, the ignition system could start the ignition, and the rocket would begin to ascend.
Time quickly passed sixteen minutes. Once it was detected that the weather conditions were normal, the staff at the control center confirmed it was correct, and then issued the launch command. "10,9,8,7..."
"3,2,1, Ignite!!"
