BIG PROBLEM! NASA's Mega Rocket can't launch cause of an Engine Major Failure... Starship's time

There were hundreds of thousands of spectators on Florida’s space coast to see the Artemis 1 launch, and millions of others around the world will watch online or on TV from home.
Even vice president Kamala Harris showed up to the event.
But in return for that grace, NASA has officially scrubbed Monday's scheduled launch of Artemis 1, what was meant to be the maiden voyage of the agency's massive and extremely expensive Space Launch System.
This is definitely a Major Fail not only for NASA but also for the U.S after spending well over $23 billion on the rocket and years of delays.

Let’s learn more about why NASA scrubbed the launch and how it’s going to move forward from this debacle in today’s episode of Alpha Tech.

Now let's dive right into today's episode:

The first test flight of NASA’s massive Space Launch System — has had its first launch window, set for Monday, 29th August.

It is difficult to overstate the significance of this mission for NASA. This will be the space agency's first launch of one of its own rockets since 2011, the final mission of the space shuttle. Even more significantly, this Artemis I mission is the first stepping stone on a path that could lead NASA, along with a bevy of international partners, back to the Moon and onto Mars.

Honestly, this is a flight test, but confidence was high in success. NASA officials said last weekend that the estimate for "loss of vehicle" during the Artemis I mission is 1 in 125. This means the agency is more than 99 percent confident that the SLS rocket will successfully launch the Orion spacecraft into orbit, after which time it will fly off to the Moon and remain there for several weeks, before splashing down in the Pacific Ocean after a 42-day mission in October.

But disappointedly, the fact is SLS hasn't left the ground yet.

The countdown began Saturday and proceeded smoothly until late Sunday night when offshore storms with rain and lightning moved within about six miles of launch complex 39B, violating NASA safety rules.

After a 55-minute delay, the six-hour fueling process finally got underway at 1:14 a.m. as engineers, working by remote control, began pumping 730,000 gallons of supercold liquid oxygen and hydrogen fuel into the SLS core stage, clearing the way for another 22,000 gallons to be pumped into the upper stage.

During a transition from “slow fill” to 10 times faster rate, sensors detected higher-than-allowable concentrations of hydrogen in housing around an 8-inch umbilical that delivers propellants to the base of the core stage. That indicated a leak in a quick-disconnect fitting.

After reverting back to slow fill and allowing temperatures to equalize across the plumbing, fast fill was restarted and this time around, there were no issues.
