Yesterday, Eagle Sauce's SLS rocket, which carries the dream of Eagle Sauce returning to the moon, was originally planned to fly for the first time in 2016, after 16 delays for various reasons, leaked fuel, resisted hurricanes, and overspent from 7 billion green coins to more than 20 billion green coins, and before launch, two Kitty hawk engineers who were not afraid of death had to rush into the dangerous area to twist the valve and experienced many tribulations of the rocket, and finally launched successfully in the spotlight.
Picture: As one of the three ace pigeons in the old aerospace industry (NASA Webb Deep Space Telescope, Maozi's Science Experimental Module, Boeing SLS rocket), ace pigeons are finally not pigeons, which is gratifying and congratulatory.
The successful launch of this rocket also made the dozen friends who have participated in this project in the past 6 years - John Cow, Foot Basin Chicken, Yidu, Maple Leaf, Ermao, Stick, Po Xian, Kangaroo, etc. put down their long-hanging hearts.
But in addition to the cheers of the successful launch of this rocket, it has never been able to cover up such a doubt or shadow, that is, how the launch of this SLS looks like NASA was forced to force (deceive) to (through) the launch (fee) fire.
First of all, this SLS rocket has a huge problem from the initial design, the rocket core first stage uses the technical heritage of NASA to keep the space shuttle, RS-25 rocket engine makes SLS have surging power, but the second stage uses the core second stage of the retired Delta 4 series rocket.
The entire core stage is equipped with an RL-10B-2 expansion cycle hydrogen-oxygen engine with a vacuum thrust of 11 tons, and this meow's toothpick drills tofu! Although the thrust can be increased by replacing 4 improved RL-10C engines in the core stage, why not verify it earlier? Take a retired gadget to make up the numbers?
Then, NASA, which has been cut by various funds since the 90s, still can't learn to live a stressful life, although SLS uses mature technology, but this RS-25 thing could have been reused more than a dozen times, but was actually waved by NASA as a disposable item, no matter how rich the local tyrants are not so burned, so overspending, is inevitable, twice as much, small meaning.
Picture: RS-25 engine, originally the main engine of the Eagle Sauce space shuttle, was used by NASA as the first stage of the SLS rocket, which could have been reused more than 10 times, but the arrogant Eagle Sauce was directly used as a disposable item, which led to the single launch cost of the SLS rocket directly soared to 2 billion green coins.
Finally, since this thing officially entered the launch site, there have been many twists and turns, and the September launch preparation first found sensor anomalies and hydrogen fuel leaks, and after repairing the problem, the launch site was hit by Hurricane Ian, and the September launch plan was completely canceled.
Because the lunar orbit launch requires a specific time period, in order to meet the window period, the launch can only be postponed to November 14, 2022, and when it encounters Hurricane Nicole again, NASA simply does not do anything and directly lets SLS stand on the launch pad to resist the hurricane.
The SLS rocket, which can theoretically carry a wind speed of 85 km / h, has withstood the baptism of a hurricane of 86 km / h, even so, NASA is forced to press the launch button, successful, everyone is happy, failed, dump the hurricane.
NASA is not at a loss!!!
So a very serious question is thick, that is, what is the reason? Let NASA, which has always been cautious in the aerospace field, directly and so boldly and forcibly launch this SLS, which has suffered many twists and turns, and its safety and reliability have been greatly reduced?
At the end of the day, the forced !!!
On the one hand, there is internal pressure, NASA never dreamed of, its own cultivation, money to technology to talents, trying to reduce the cost of space, used to continue its dream of the sea of stars (SpaceX) has begun to show its fangs, although now Iron Man Musk is still promising NASA's big brother, but the heart of the anti-bone boy is already known to passers-by.
This is not only because Empty Fork successfully won the contract for the Eagle Sauce manned lunar module, nor is it just that Empty Fork's "Starship" program has been trying to replace the SLS rocket to carry out Eagle Sauce's "Artemis" mission (with the successful launch of the SLS rocket, if the Starship of the Air Fork is also successfully launched, the two will jointly carry out the "Artemis-3" mission as early as 2025), which is more because the Air Fork began to try to encroach on the right to set international space standards, which has been controlled by NASA. This formulation right includes, but is not limited to, satellite manufacturing, aerospace parameters, port standards, etc...
Picture: SLS rocket and starship, the two represent different technical paths and different standards, SLS rocket is simple and reliable, but the price is expensive to fly, starship complex but cheap, the two are in a competitive situation, is conducive to the development of eagle sauce aerospace industry, but obviously, the empty fork does not intend to compete, but through such as cooperation with the eagle sauce military, cooperation with eagle sauce telecommunications department and other off-market moves, squeeze the original NASA-controlled standard setting power space, try to be replaced by their own commercial company.
The reason why Eagle Sauce has been able to dominate space for many years is not only because of the crazy money thrown out of a bunch of results during the Cold War, but also in the development of a series of aerospace standards based on the results, as a rare institution with human initiative, NASA cultivated the empty fork is intended to reduce the cost of space, after all, NASA's annual budget is less than 20 times its peak compared to its peak, and it is still decreasing year by year, so that the empty fork serves NASA's ambition to explore the unknown universe, But the empty fork is not so innocent and kind, instead of serving your ethereal dreams, serving the stock is not fragrant?
Backlash is inevitable!!!
And this standard-setting right is also subject to pressure from the other side of the ocean, Mu is at fault, that is, a certain innocent, kind, cute and innocent - rabbit!!!
Although the building of the pit often ridicules NASA as a rabbit's licking dog, after all, whether it is through the opening of the downlink data link of the "Juno" probe, the rabbit saved billions of green coins to complete the deep space network mapping, or through the cow and cow this middleman to sell the Hawaii Observatory, or take the initiative to find a rabbit to sell the ass to share lunar data in exchange for the support of the rabbit's "Magpie Bridge" satellite, this meow is not licking what?
But even if it is licking dogs and goddesses, there must be a question of who is up and who is down!!!
A certain oriental long ear since entering the new century pocket of small money money is increasing, also with the dream of the sea of stars in their pursuit of the field of aerospace can be described as a rapid progress, although in many technologies still lag behind the big business of the eagle sauce, but aerospace this thing, many times, the force of the brick fly, the money will take off!!!
And the rabbit in this piece, does not skimp on it!!!
Picture: Rabbit's new generation rocket that appeared at the Zhuhai Air Show, a new generation of manned rocket: 3 and a half stages, 5 + 5 + 5 + 5m, 90 meters! The carrying capacity of 27 tons of Earth-Moon transfer orbit, the take-off mass of 2187 tons, and the takeoff thrust of 2678KN are no less than the SLS rocket launched by Eagle Sauce with great effort, and its basic model is the improved version of the current Chang Five rocket; A new generation of heavy rockets: 3 stages, 10+10+10m, 108 meters, Earth-Moon orbit 50 tons, low Earth orbit 150 tons! The take-off mass is 4180 tons, and it is not a problem for the subsequent improved model to break 10,000 tons!!!
What's more, the rabbit also began to intervene in the formulation of standards, after the rabbit's Tiangong was officially completed, Eagle Sauce did not want to have the space station of the rabbit on several cabinets, not on data sharing, anyway, it was not so once or twice, but the port standard of the rabbit directly stuck Eagle Sauce's dream, either, according to our standards, or, you play by yourself.
This is just the standard of the space station, this satellite standard to a set, this rocket standard to a set of etc., etc., etc., as a certain long-eared space exploration activity becomes more frequent, the rabbit this set of standards will continue to be promoted and become the standard that all the friends in the earth mansion abide by, this no, a local tycoon in the Middle East will throw money to let the rabbit send a 10 kg gadget to the sky, completely in accordance with the standard of the rabbit Oh.
Figure: (from the Rabbit Astronautical Association) "Cubic Star Internal Load Structure Design Requirements" after the standardized payload is installed on the satellite platform, the standard has been officially implemented since June 2020.
NASA saw the appearance of a certain long ear, and it was strange that it was not in a hurry!!!
But NASA is no longer the behemoth monster that once occupied a pivotal role in the GDP of Eagle Sauce in the past, the machetes of Capitol Hill grandfathers hang high above NASA's head all the time, and in the face of the current internal and external pressure, NASA has not yet had a good way to break the game.
If you don't have money, it's for nothing...
As mentioned earlier, the three major ace pigeons in space, NASA Webb Deep Space Telescope, Maozi's Science Experimental Module, and Boeing SLS rockets have gone up two in decades, is Eagle sauce complete?
Think too much...
The new three ace pigeons are already on the way...
The ULA Vulcan rocket, Blue Origin New Glenn rocket, and Boeing manned Starship are summoning ahead!!!
The road ahead is slim!!!
