The first arrow of the new-generation American moon landing rocket SLS has left VAB for the fourth time on November 4 and stood on the Kennedy Space Center 39B launch pad, its ultimate fate has touched the hearts of many people. According to the latest news, its launch time and have been postponed. On the evening of November 8 local time, NASA issued a statement saying that since the tropical storm "Nicole" is expected to increase to Class 1 hurricane when it lands in Florida, USA, the "Artemis One" launch mission originally scheduled to be carried out on November 14 local time has been cancelled, and the launch date will be postponed for two days.

encountered a storm, and the SLS's first flight will be postponed for another two days. Interestingly, NASA seems to be transformed into a "good mother" who cares about employees at this moment, saying that "adjusting the launch date will enable employees to meet the needs of their families and provide sufficient logistics time after the storm." "The launch time of 'Artemis One' is changed to November 16, and the conditions for waiting for employees to return to work safely are met and the situation after the storm is checked."

NASA suddenly cared for the employees, which made people uncomfortable

Behind a large number of difficult-to-mouth literal translations, the outside world directly saw through NASA's real intention, but unfortunately there are not many excuses left for NASA. I still remember that on November 4, when SLS first shot left VAB, media reports said that this was its last chance. The launch window on November 14 was only between 12:07 noon and 13:16 noon, and there was no backup window.

Originally, didn’t it be agreed that there was only one 69-minute launch window?

But now, NASA has changed its words and said that the new launch window is within two hours from 1:04 am on November 16, and has also set November 19 as an alternative launch date, and said that it can also coordinate relevant arrangements with US Space Force . After seeing this, the editor understands that NASA really doesn't plan to launch the SLS first arrow. It has created several unplanned time windows to walk us to play. Perhaps deep in the hearts of NASA and Boeing , I am still looking forward to the "Nicole" tropical storm coming more violently. It is best to blow this "hot" rocket. This way everything is easy to explain. If you don't launch or fail to launch, you can blame nature for the head. After all, Boeing once found a group of birds and Indian programmer to take the blame for the crash of the 737MAX passenger plane. They are familiar with this operation.

737MAX can find a group of birds to take the blame. Boeing’s blaming technology has always been the first-class

When it comes to SLS, will Boeing use daily skills?

In fact, rolling back to VAB three times has already put the structure of this SLS first arrow to the limit, and it is impossible to have another "return to the factory". The frequent addition of propellant to release propellant also makes the possible hydrogen embrittlement problem even more serious, and there will be no more launch windows. Moreover, in more than a month after the third round of VAB, NASA and Boeing engineers conducted a full physical examination of the SLS rocket, but failed to find the real reason for its fuel leakage. They could only control it to ensure minimum safety. However, just two days ago, there was unconfirmed news that SLS was leaking again.

It is said that the

SLS rocket leaked again, but the funding plan has to continue to be implemented. NASA has even planned the next batch of moon landing rockets with Boeing. According to public information, they are developing Block 1B based on SLS Block 1. The low-Earth orbit carrying capacity is expected to be increased from 95 tons of Block 1 to 105 tons, and the earth-moon transfer orbit load capacity is expected to be increased from 27 tons of Block 1 to 38 tons. There will even be a Block 1B Cargo model with a TLI load of 42 tons, a 43 tons Block 2 Crew and a 46 tons Block 2 Cargo model. The so-called Block 2 is actually the cargo version of the SLS rocket. The United States plans to use multiple SLS rockets to achieve a mission to return to the moon, rather than a single arrival in the era of "Saturn" 5 and "Apollo".The basis for improving the load capacity of

SLS Block 1B is planned to have several models. The basis for improving the load capacity of

SLS Block 1B is planned to replace a stronger EUS upper stage. Now the upper stage of the Block I rocket is ICPS, which only uses one RL-10B2 engine. EUS plans to use 4 engines and replace a larger capacity liquid hydrogen and liquid oxygen storage tank, so that 4 astronauts and "Orion" spacecraft can be sent to the lunar orbit at one time. It is expected that NASA will use the SLS Block 1B model on the fourth rocket that returns to the moon.

However, if you say a thousand words, NASA's most important thing is to choose to face the reality of SLS. If the first arrow cannot be launched in the end, the plan to return to the moon will definitely be postponed again. If it is forcibly launched, if it is exploded, the entire SLS rocket project may be discontinued. Then the United States' plan to return to the moon will have to wait for the first orbital-level test flight of the " starship " to regain its momentum.
