NASA has many ambitious projects lined up for 2021 and one of the main goals of the space agency is the launch of Artemis I, which is an unmanned moon mission. This moon mission will feature its Orion spacecraft and Space Launch System (SLS) rocket, which is capable of sending humans to the moon. However, before the mission, the agency needs to go for a fiery SLS test. NASA has almost reached the end of the Green Run test of the SLS rocket, which sets the backbone of the SLS rocket through its paces before the agency actually launches it. The eighth and final part of the test series will take place in mid-January when NASA starts an exciting fiery SLS test. Scientists from NASA have said that the forthcoming SLS test will fire up RS-25 engines of all four stages at the same time for up to eight minutes to simulate the performance of the core stage during the launch. As per the report, SLS has undergone many delays during its development but still, the agency has kept this mission among its most anticipated projects to send humans back to the moon in 2024 via the Artemis Program. A report has claimed that the launch of this upcoming mission depends on the costs of the program, the SLS delays, and scheduling effects due to the COVID19 pandemic.
Scientists have said that such test fires are quite interesting. For example, last year, the world has seen how SLS boosters have illuminated the Utah desert and turned sand into glass. The officials from the US-based space agency NASA have said that the SLS Green Run Test is going to take place at the Stennis Space Center in Mississippi. The decision of going ahead with the Green run test has come after the agency has rectified an unforeseen problem with a previous test, which has been a wet dress rehearsal. As per the scientists, for the first time, cryogenic, or super cold, liquid propellant has been fully loaded into and drained from the two immense tanks of the SLS core stage during the previous test.
Experts have found that during the test, the wet dress rehearsal has suspended a little early. However, NASA has found out the issue and has reported that it has been a timing issue. Scientists have corrected the issue later. The officials from the agency have said that this issue will not affect the hot fire test anymore. As per the report, if everything falls in place, NASA will able to launch Artemis I at the end of 2021.
