NASA: Once the new moon landing rocket misses the launch window on the 6th, the first flight may be postponed to October

[Global Times Comprehensive Report] The US "Space Launch System (SLS)" heavy rocket launching in the early morning of September 4, Beijing time was postponed due to the engine failure, and the first flight task was canceled because of the fuel leakage problem. The project team of the National Aeronautics and Space Agency (NASA) said that due to the problem of liquid hydrogen leakage, SLS Rockets will not launch before they are not fully prepared. Once the launch window on September 6 is missed, Shoufei may be postponed to October.

On August 29th, Eastern Time, due to the cooling problem with the Rocket-class RS-25 engine when adding a low-temperature pushing agent to the core storage tank, NASA temporarily canceled the "space launch system" planned to be held on that day. Heavy rocket first flight task. The SLS Rockets then re -launched at 2:17 pm on September 3, Eastern time.

However, on September 3rd in the eastern time, when the low -temperature pushing agent was added to the SLS rocket core, the rocket leaked in liquid hydrogen fuel. NASA stated on the official website that the project team engineers adopted a variety of methods, and they tried to block the leakage points three times. Eventually, 3 hours before the launch, NASA announced the suspension of the "Artemis 1" launch task again. In the next few days, it will carry out uninstallation of pushing agent operations at the Kennedy Space Center 39B launch station, and at the same time evaluate it to decide whether to replace the sealing parts on the launch station or push the Rockets back to the total installation building for maintenance.

At the NASA mission briefing held on September 3, local time, the project team stated that due to the problem of liquid hydrogen leakage, it was not fully prepared, the "Artemis 1" moon landing rocket will not launch.

NASA Director Bill Nelson also said, "We will not launch until we think it is correct." He said that the problem of liquid hydrogen leakage on the day was more serious than the previous one. question. Therefore, before launching again, they need to conduct data analysis and fault investigation for a few weeks, so the management team may decide the time of launch again this week.

Bill Nelson said that if the SLS rocket is shipped back to the total installation building, there will be no more launch opportunities before October. Because there are other launch tasks in launching stations, the rocket will be delayed after repair. By mid -October. (Fan Wei)
