SLS megarocket of NASA for the moon restarts testing following hiccup of equipment


Jan 3, 2021

The great news is on offer because of the postponed testing of the Space Launch System rocket days after the NASA agency ratified two international memoranda of understanding relating to the Artemis moon program. “Green run” tests on the latest Space Launch System (SLS) megarocket, scheduled for its November 2021 deployment, are going ahead again after ground equipment issues put the tests behind earlier this month, NASA Agency said on December 17. 

The rocket itself is perfect, NASA said during a December 11 media conference. Still, the seven out of eight “wet dress” practice drills at Stennis Space Center of NASA in Mississippi were stalled by temperature problems related to ground equipment to fuel the tank. However, as of Thursday (December 17), contractors Boeing and NASA began to restart the drill, a “wet dress rehearsal” involving thoroughly filling the liquid hydrogen as well as liquid oxygen tanks of the SLS central stage this week.

“Upon conclusion of a wet dress rehearsal, the group will spend a couple of days evaluating data to identify if NASA Space Agency is willing to begin with the last green run test: hot fire if all four engines will fire, designed to simulate the countdown as well as the deployment of Artemis 1 mission,” NASA says in a statement Artemis website blog. If the wet practice run data review is complete, the hot-fire test schedule will be set, NASA continued.

Currently, the SLS being evaluated is set to launch an Orion spacecraft for an uncrewed round-the-moon journey in late 2021; however, the experiments need to be completed quickly to finish the final shipping and development to Florida in order to reach the flight date. This mission, referred to as Artemis 1, should be accomplished before the crewed Artemis 2 moon orbit program flies to its planned 2023 date, as well as, throughout Artemis 3, NASA’s trying to land people on the Moon by 2024.

John Honeycutt, who serves at the Marshall Space Flight Center of NASA as SLS Program Manager in Alabama, said about Artemis 1 SLS trials during the December 11 videoconference, “We are getting to the moment where we have got hardly any margin remaining in the timeline compared to our dedication to our delivery date.” Not only does it matter to NASA Agency, but also to its foreign allies, to travel SLS on schedule. Both the Canadian Space Agency as well as the European Space Agency stated earlier in the week that they had reached agreements with NASA surrounding involvement in the Artemis program. The Canadian Space Agency has confirmed that on Artemis 2 program in 2023, it would fly a space explorer who is yet to be identified; it will be the first time that someone other than an American has left the Earth orbit.
