NASA is currently developing a program calledSLS core level will be tested more this month and it is still sitting on the B-2 test bench at the Stanis Space Center. The huge rocket is 212 feet high and is stronger than any rocket used since the 1960s.

The upcoming test is

There are two remaining core levels, and No. 7 is called wet loading drill. The test includes injecting liquid hydrogen and liquid oxygen into the core stage tank. The rocket has 500000 gallons of liquid hydrogen and 200000 gallons of liquid oxygen. The extremely cold propellant will be delivered from the barge to the core stage tank within 6.5 hours.

Engineers will collect data during testing and compare it with mathematical models to determine whether the overall system behaves as expected. The team will also simulate a large countdown during the wet dress rehearsal, which will launch until 33 seconds before launch. The eighth and final test is called the heat test. With the core stage fixed on the bracket, the hot fire test will ignite four rs-25 engines and ignite them together for the first time. The engine will burn full-time, producing a thrust of 1.6 million pounds. When the engine ignites, it will enter a huge bucket with plenty of water to prevent it from melting the metal frame connected to the rocket.

If all goes well, the first flight test of SLS will take place next year.
