NASA preparing to test in last week of February

SLS to undergo hot fire test again, NASA preparing to test in last week of February. Taking a step further towards realizing the dream of space tourism, the US space agency NASA is going to do a hot fire test of its first space launch system (SLS) once again in February, which preparations are in full swing. Earlier this test was to be done in January but the agency closed it prematurely.

The SLS is the most important part of NASA’s Artemis program. Under this, NASA is building the most powerful rocket. It has two major parts – a liquid fuel engine and a solid fuel booster. Many boosters are used in a rocket, which exerts extra force to propel the spacecraft to lower Earth’s orbit.

A NASA official said, “The SLS tests are to be completed in eight phases. The process has been named Green Run by the agency. Its seven stages have been tested by December. Now the last phase i.e. hot fire test will be done at the beginning of the fourth week of February.

LLS engine underwent test firing in the past

The US space agency NASA’s Artemis mission will launch the Orion spacecraft with the help of a space launch system rocket to orbit the moon and return to Earth. To test it, the LLS engine underwent test firing in the past. It has four RS-25 engines. All four rocket engines were fired as they would be at launch. For the first time in these engines, firing occurred for one minute simultaneously. However, it was stopped in between. After evaluating the first hot fire and seven green run tests, NASA and Core Stage chief contractor Boeing agreed that the hot fire test should be done over a long period of time, only then could it yield true results. NASA said it would help to validate the main stage for the flight as well as minimize the risk for the main stage of the mission. NASA preparing to test in the last week of February.

The Green Run Series authenticates the designs

The Green Run series of tests have been designed to validate the core stage design and verify that the new stage is ready for flight, NASA said. The hot-fire test is the final green run test and will provide valuable data, which will also help reduce the risk for future US space exploration missions. A second hot fire test is planned for approximately eight minutes to simulate the time it takes to send a rocket into space after launch.
