Why NASA's Artemis rocket experiences a fuel leak, but SpaceX doesn't

    The launch of NASA's most powerful SLS rocket for the Artemis program has been delayed twice. The latest delay is an indicator, and the fact that the space agency relies on old technology originally developed for the Space Shuttle program, experts warn that his SLS launch is years in the making. The Difficult Space Program SLS NASA is the space agency's most powerful rocket ever. After launch, the rocket will produce 9.5 million LBS of thrust and be capable of carrying a NASA payload capacity of 86 tons.

Why NASA's Artemis rocket experiences a fuel leak, but SpaceX doesn't

    It has been lauded for using old technology, even though newer rocket technology that is reusable and cheaper already exists.In 2010 Congress asked NASA to use liquid hydrogen and liquid oxygen as propellants. A decision was made when the law was written to allow its use as a fuel.Hydrogen is the lightest element, so it is efficient and has high mileage, yet leaks can be easily repaired. The Artemis Project has more manageable alternatives, such as methane and kerosene, but the current state of power within the government is too strong.

    If Artemis fails, NASA could switch to Elon Musk's Space X, which is being tested weekly. Boot normally and return. His Elonmas, who built the rocket industry after selling PayPal to his eBay, has a problem with the high cost of launching rockets, given that existing rocket systems cannot be reused and must be destroyed in space. We are focused on solutions.

    The newest rocket, the Space Starship, is abbreviated as Metalox because it uses methane or seafoam and liquid oxygen or salmon as fuel, while the Falcon 9 and Falcon HIV use kerosene, a type of rocket-grade kerosene, and propellant. use salmon for why is this so expensive? The SLS NASA rocket leak didn't have the same problem with Space X, which has flown hundreds of rockets. SpaceX uses kerosene in its Falcon rockets because there were no rocket engines until 2007. This is methane kerosene, a type of kerosene that is cheaper, denser, and more stable at room temperature. Like hypergolic fuel, kerosene is non-toxic and easy to handle. It is light to transport, has no leakage problems like hydrogen, has much lower explosive power compared to liquid hydrogen, and currently has four rocket propellant systems.

    Usually the first solid propellant, very smooth second kerosene and liquid oxygen, third liquid hydrogen and oxygen, fourth hypergonic propellant, last or fifth methane or seawater and liquid oxygen solids Propellant rockets are very easy to use. The design and construction of this type of rocket typically consists of steel tubes filled with solid rocket propellant and oxidizer. When this fuel is ignited, it burns rapidly, releasing hot gases that pass through the nozzle to create thrust, but these solid-fuel rockets have a different problem than liquid-fueled engines. Turning them on burns the entire Protolant until it's depleted. Therefore, SpaceX will not use solid rockets, but hydrogen is a lightweight and extremely powerful rocket propellant combined with liquid oxygen, which provides the highest specific impulse or efficiency.

    Additionally, liquid hydrogen has three times the energy density of kerosene in terms of mass, but liquid hydrogen or LH2 presents a major engineering challenge. Hydrogen boils at minus 253 degrees Celsius. Therefore, it must be stored at minus 253 degrees and requires very special storage containers to store and transport. Hydrogen has a density of 0.071 grams per ml, while liquid kerosene or rb1 has a density of 0.82 grams per ml. In other words, liquid hydrogen has 12 times the energy density of kerosene. It must also prevent liquid hydrogen from boiling the rocket, and must be insulated from all heat sources such as rocket engine exhaust, air friction during launch, and radiation.

    Solar-thermal hydrogen rockets require advanced metallurgical engineering to prevent metallic hydrogen from solidifying. The molecules of liquid hydrogen are so small that light hydrogen escapes very easily, making them brittle when exposed to extreme cold from liquid hydrogen. Liquid hydrogen can enter through small holes in the welds Special ice where liquid hydrogen is also very expensive There are many problems with liquid hydrogen, so they launched a new space program with a clean set design.SpaceX Falcon We didn't have hydrogen for rockets.

    Space Falcon rockets use kerosene or rocket grade kerosene and liquid oxygen, which is nothing new for over 50 years. There are also some rockets that use this type of strut. Carcinogenicity As a result, Space can fit more fuel into rockets with less weight, and rocket-grade kerosene to carry larger payloads into orbit. Alternatively, the RB1 can be transported using regular petrol tankers.

    Without any amendment Space makes use of kerosene and liquid oxygen which could be very bloodless it is why they load this propellant proper earlier than the release of the rocket however kerosene additionally has a drawback due to the fact this gas is kerosene kind so it produces gel coke and polymerization withinside the Merlin rocket engine therefore after each rocket release Space X desires to easy its rocket engine very well this technique is highly-priced and stops Space from reusing their rockets sequentially despite the fact that the Merlin Falcon nine and Falcon heavy engines use liquid herosine the Starship raptor engines use methane liquid or seafood as a gas methane burns cleanly and is a much advanced gas for reusable rockets these days liquid methane or Seal for is a normally used rocket propellant but it became now no longer as conventional earlier than 2007 this trouble confronted with the aid of using artemis Nasa very touchy as it pertains to engine protection and challenge operations as an entire there's no records on while the SLS will honestly be capable of release if there's no sizeable answer it's miles probably that Space gets the undertaking of changing the SLS artemis rocket Okay,
