Bad news for diets The NASA and the dream of bringing man back to the Moon. The Space Launch System (SLS) mega rocket failed again for the third time in a critical test.
According to what was reported by the Xataka site, the SLS stalled in a critical test that consists of filling the fuel tanks and doing a launch sequence.
After three failed attempts, the US space agency is confident that this time it will be able to overcome this test which delayed the planned launch of the mission. Artemis 1which aims to bring humans back to the Moon.
With Artemis, the agency seeks to bring American astronauts to our natural satellite for the first time in over 50 years. The SLS is the key to this, and they need the rocket to build the Lunar Gateway, a small space station orbiting the Moon.
In addition, NASA intends to use the mega rocket to enable future manned travel to Mars. This mission and others will be complicated in the future due to cost overruns and delays in the SLS program.
This Saturday, June 18, the SLS rocket and the Orón capsule will begin ‘wet suit rehearsal’, from Launch Pad 39B at Kennedy Space Center in Florida, according to a report from spacenews.com.
What is the general wet test?
The wet dress rehearsal will last two days and will involve a large number of engineers and technicians at various locations on the launch pad.
The Kennedy Space Center Launch Control Center team will interface with the Johnson Space Center Mission Control Center (Houston), Space Force East Field and the SLS Engineering Support Center (Alabama).
Once the countdown has started, refueling will beginfollowing the same schedule that will be used on the launch day of Artemis I. At the same time, controllers will test the various systems of the Orion rocket and spacecraft.
The objective of the test is to test all phases of the launch, including weather reports, expected holding, conditioning and refueling.
The general wet test includes stop the countdown 10 seconds before the simulated launch time, i.e. a few moments before the engines start. This test is of great importance because the flight director could decide not to proceed with an actual launch if a technical or weather problem arises.
Technically, NASA managed to meet some test goals in previous attempts, but only managed to charge 49% of the middle stage liquid oxygen tank and 5% of the liquid hydrogen tank. This was due to a problem with a faulty check valve in the rocket’s upper stage and a hydrogen leak in the tail service mast.
If all goes well, the rocket and capsule will return to the Vehicle Assembly Building (VAB). There, the technicians will remove a series of sensors included specifically for the test and which are not necessary for the real mission and will carry out the final checks.
The next release window falls between June 26 and August 10, period in which the SLS could take off, but experts like NASA associate administrator Jim Free believe it is too early. next window begins August 23 and ends September 6.
