Nasa has assembled two booster rockets that will power the สูตรเล่นสล็อต new rocket launch system - the SLS.The SLS, or Space Launch System, is a rocket that will send astronauts to the moon under the US Artemis program.Over the past several months, workers at Florida's Kennedy Space Center have stacked 10 sections of the booster rocket vertically.When operating, the SLS will be the most powerful rocket in the world.It will be able to produce up to 8.8 million pounds of thrust, making it 15% more powerful than the Saturn V rocket that carried out Apollo moon missions.
The SLS consists of a large main rod with four powerful engines at the base and two auxiliary rockets (SRBs) mounted on either side.The two completed SRBs at the Kennedy Space Center will fly in the first SLS launch, known as Artemis 1, scheduled for late 2021.Each of the same boosters is divided into five sections trapped by larger rocket components known as forward and stern assemblies.The SRB is stacked on top of a structure called a mobile launcher that will support SLS testing, payment and servicing as well as transfer to the launch pad at the Kennedy Space Center.The booster, similar to the one currently helping launch the retired space shuttles, will provide 75% of the total thrust when lifted.
On Twitter, Charles Precourt, vice president of propulsion for Northrop Grumman, maker of SRB, said it was "exciting to see a full stack of boosters."Engineers at Nasa's Exploration Ground Systems team have positioned the first part on November 21, 2020 and will continue until the final rhinoplasty on March 2 this year.Stacking a solid rocket booster is a huge success," said Cliflanham, senior vehicle operations manager. "It means the rocket is being assembled on a hand-held launcher, and we're at the final stage of a long journey - the launch of Artemis 1The SLS has the thrust needed to drive Nasa's next-generation crew vehicle, the Orion, to the moon without docking, thanks to a separate propulsion phase in Earth orbit.
America is returning to the moon under Project Artemis (named after Apollo sister in Greek mythology), the project was initiated under Donald Trump's presidency. But in February, Biden's administration backed the moon shoot.The Trump White House has set an aggressive target date of 2024 for the US space agency to make the first human moon landing since 1972, however, the Biden administration has not mentioned this timeline. Which leads to speculation that the date will slipThe last large piece of SLS pending drilling into the mobile launcher is the main orange phase, currently under evaluation at Nasa's Stennis Space Center near Bay St Louis, Mississippi.
Nasa plans to conduct a "hotfire" test of the core in mid-March, which will involve the ignition of all four engines. The engineers aim to fire them for the full eight minutes for the SLS to reach space.During the first attempt at a hot fire in January, a problem with the core hydraulics ended the test just a minute later.The initial flight of the SLS, scheduled for late 2021, will see a idle Orion spacecraft launch rocket on its way around the moon to complete a full assessment of the two vehicles.Each of the connected joints of the solid rocket booster has a limited lifespan of 12 months.The booster stacking means the watch is about to launch - although engineers say there may be a way to extend the certification period.
