Giant rocket launch tomorrow morning! Unmanned mission to orbit the moon. It is supposed to be as loud as 10,000 jet engines. This rocket is larger than the Saturn V that took man to the moon.

I don't think it's larger than a Saturn V, but does have more thrust.

----------------Saturn----------Art
Propulsion--- 3 stages------ 2 stages
Height ----- 363 feet------- 212 feet
Diameter --- 33 feet------ 27.6 feet
Weight ---- 6.5 million lbs.------ 5.75 million lbs.
Thrust ----- 7.5 million lbs. ------ 8.8 million lbs.

So smaller over all - but the crew module is bigger with longer duration.

50 as of February (Feb 1972 was when Apollo 18 was supposed to launch).

Smaller, lighter but with more than a million pounds more thrust.

No matter which way you spin it, that's a win.

It's also interesting to see NASA again involved in a space race. But this time instead of the ruskies, they're racing against Elon.

And like all governments, they'll cheat if they need to by having the FAA keep Elon's tests on the ground.

I would hope there would be some significant performance improvements over half a century of development.

The Saturn used what was essentially just scale-up of early proven engine designs to get something functional before Kennedy's deadline and not decades later.

We will see soon if all that NASA and contractor computing and design modeling power devoted to Artemis was up to snuff.

Almost a year late and over 90 Billion in cost, so far to not even make it to the mark 50 years old. Color me unimpressed.

I think the delay was due to development of computer systems capable of handling so much data. It is my understanding that the Apollo 11 Lunar Excursion Module landed on the moon using 4K of RAM.
There is a recent report of a new material "cubic boron" that may far exceed silicon as a semiconductor. This material with Artificial Intelligence computing maybe a breakthrough for space transportation systems.

New launch window opens Friday. 500,000 extra people in the Space Coast area to see it liftoff.
NASA had the same problem with STS-26. Leaking hydrogen line! I said just cut a hole in the payload bay, wrap the line with tape and put a clamp around it. That is just what they did. It launched on this same day of 1988. Sorry, I can't make any winning suggestions today. I desperately need surgery. I am sick AF...

Hell I'll drive down there before a year is up. I got my eye on a few Corvettes. The SLS is basically the same as the Space Shuttle. Same SSME's , same SRB's with an extra section.

Can't be any worse than this boiled egg I made today. It exploded!

The boiled egg pic - with the obligatory toes in the pic. Doesn't look like that would have been fun to clean up but here's hoping Artemis doesn't have a similar event at liftoff.

Best hard boiled eggs- Steam for 13 minutes and drop in an ice bath for about 10 minutes.

Perfect color and texture. The shells come off in two pieces. Every time I do it I am amazed how good they turn out.

The egg failure was definitely a "loss of coolant " event. The SLS is experiencing the same anomaly.
The engines are fed liquid hydrogen to cool them preflight and also post launch. The fuel is the coolant. The nozzles have 1080 tubes of liquid hydrogen flowing through them before ignition. Video below is a silly, but close enough analogy of the system.

https://spacenews.com/nasa-continues-to-study-issues-that-caused-artemis-1-launch-scrub/

"Controllers scrubbed the launch when they were unable to resolve a hydrogen bleed line issue with one of four RS-25 engines in the core stage. The bleed is designed to flow hydrogen into the engines to condition them thermally for flight. For three of the engines, the bleed was working as planned, cooling the engines to the required temperature, but for the fourth, designated engine #3, it did not cool down sufficiently."

Herr is a sad fact, one SLS has cost equavlent to one third of Apollo and Gemini combined.

It is an expensive HUGE project, best to side on caution and check it out than take the chance a failure, especially since the whole world is watching!

Problem is, they might need to 'hanger' the thing to work on it. Next 2 week launch windows are mid Sept. and mid Oct. from what I have heard. One of the important variables of launch time is calculating an Earth re-entry, upon mission end, during daylight.
I can't even imagine the pressure on these gals/guys/geeks who work on or are responsible for this thing, good luck and I know you can make it happen. Take your time.

The main booster is made from leftover Space Shuttle parts. Strapping solid rocket boosters to big tanks of hydrogen and oxygen seems a recipe for disaster. Last I heard the engine temp sensor had an anomaly. Then an 8 inch hydrogen breakaway fuel line has a seal leaking. I was hoping for a trouble free launch.

It's a government-run, government-paid project. Failure is not an option because there'd be blame, but delays and over-runs are par for the course.

At this rate, Starship will beat SLS to orbit, and even if this one finally flies, SLS is already irrelevant and outdated.

FYI, there's a tenuous Colorado connection to this launch. The launch contains a CubeSat called OMOTENASHI (https://en.wikipedia.org/wiki/OMOTENASHI) (which is one heck of a backronym (https://en.wikipedia.org/wiki/Backronym)). OMOTENASHI is planned to survive somewhat of a "crash landing" on the moon.

OMOTENASHI will transmit information back to earth on the 70cm band, and the Deep Space Exploration Society (http://dses.science/) here in Colorado will be trying to pick up their broadcasts with their 18m radio telescope located in Haswell, Colorado as a backup to Japan's assets, since OMOTENASHI is supposed to land while the moon is in full view of DSES' dish (if the launch goes off tonight during the launch window).

Why didn't they launch during the day so it could use solar panels as energy?

Very impressive 'night' launch, they had a 2-hr. window, glad it went well.

The numbers are staggering on the rockets weight, fuel weight, booster's and main engine's output, speed and everything else.

Awesome (but kind of expensive) work NASA!

$20 billion, give or take.

President Biden just requested an additional $37 billion to fund this month's Ukraine war, as the total nears $100 billion in ten months.

Your weight on the Moon is 16.5% what you would experience on Earth. If we launched from the moon, we would need far less fuel to get to Mars.

Until a large asteroid hits the planet, then we will wonder why we didn't do anything. An ELE (extinction level event) is due to the mathematical odds. The last known large impact was in Arizona. If it happened today, we probably would not survive in Colorado.
