NASA plans to ignite the most powerful rocket ever built on January 17 said in a statement the agency.
This will be the first launch of the space launch system (SLS), the long-awaited (and delayed) rocket spacecraft that NASA plans to use for non-commercial human spaceflight. This is a central element of NASA’s Artemis program, a crew landing mission, in the language often used by NASA, “the first woman and the next man” on the moon.
During this first ignition, only the liquid fuel engines in the rocket core will be tested, without the solid fuel boosters that will one day help transport the SLS into orbit.
When the SLS core is tested, it will become the most powerful rocket ever fired on Earth.
At 322 feet (98 meters) high, the SLS stands with its head lower than the 363-foot (1
Raw power does not translate precisely into how much mass a rocket can carry in space.
When completed, if all goes well, the SLS will have the capacity to carry more than 27 tons (24,000 kilograms) to the moon – far more than the 24 tons (22,000 kilograms) that the space shuttle pulled into low Earth orbit, though and technically less than Saturn V carried to the moon. (However, according to the sister site of Live Science Space.com, less of the SLS’s payload will be lost for the various rocket stages and fuel, making the SLS generally a better payload.
The test will cover an eight-step testing program that NASA called the SLS “green run.”
The seventh part, successfully completed on December 20, 2020, showed that the rocket can be loaded with 700,000 gallons (265,000 liters) of supercooled liquid fuel and then remove this fuel without incident.
The hot fire will occur at NASA’s Stenis Space Center near St. Louis Bay, Mississippi.
“During our Green Run wet rehearsal test, the main stage, stage controller and Green Run software performed flawlessly and there were no leaks when the tanks were fully filled and filled in about two hours,” Julie Basler, SLS Space Scene Manager NASA’s Marshall Flight Center in Huntsville, Alabama, the statement said. “The data from all the tests so far has given us the confidence to continue with the hot fire.”
The test will probably be broadcast on NASA’s YouTube channel.
