For astronauts to reach the moon, they need a big rocket, the Space Launch System is that rocket, and since the Saturn V took NASA astronauts to the moon in the 1960s and 1970s, The most powerful rocket. The launch pad, which is waiting to be launched Wednesday, is 322 feet tall and when loaded with propellant he weighs 5.5 million pounds.
It can lift over 200,000 pounds into low earth orbit and deliver nearly 60,000 pounds of payload to the moon. The cargo for this launch is Orion, a capsule that is unmanned for this flight but can carry four astronauts.
Known as the SLS, the rocket resembles a stretched outer tank used by retired space shuttles, and the side boosters that help it get to space are very similar to the engines that the shuttle used. .
This is by design. To simplify the development of the New Moon rocket, NASA reused much of his 1970s space shuttle technology. The rocket’s center stage is 27.6 feet in diameter, the same diameter as the 1970s Shuttle’s outer tank, and is covered with the same orange insulation.
The four core stage engines are the same as the main space shuttle engines. His first three Artemis missions actually use engines taken from old shuttles and refurbished. NASA will run out of old shuttle engines after Artemis IV, as the SLS rocket will only be used once for him. Artemis V and later missions will require new engines.
The side booster is a longer version of the one used in space shuttle flights. During the Shuttle era, NASA salvaged and reused similar boosters. However, he only launches about once a year for his system, and the agency decided it would be easier and more economical to submerge the boosters in the ocean and use a new booster for each flight.
The second stage of the SLS, which will be propelled on its path to the moon once the Orion capsule reaches low Earth orbit, is essentially a modified version of that used in another rocket called the Delta IV. . A new upgraded second stage will be used for Artemis IV, making the rocket even more powerful.
Development of the Orion Crew Capsule began in 2006 as part of Constellation. This is an early moon program launched under President George W. Bush. Constellation costs skyrocketed, and the Obama administration tried to cancel it outright in his 2010.
However, Congress rebelled against the decision, leading to the resurrection of Orion and Ares V. This was the planned heavy lift rocket for the Constellation, which became the Space Launch System.
The Orion capsule is designed for trips lasting several weeks in deep space beyond low Earth orbit. That means it’s bigger than the Crew Dragon capsule that carries astronauts to the International Space Station, but it takes up a little less space inside, leaving room for more robust life support systems.
