Nothing but H20, where's the moon base ?

General Foods has Tang X-treme Boost and Gluten-Free Space Food Sticks ready in the wings to coincide with the launch

a friend of mine worked on its initial design in the early 70s

he died about 5 years ago, kinda a grumpy old man type but I enjoyed working with him

Funny thing, they will be using old shuttle engines (finest engines known to man), but in expendable mode.

But despite using existing engines, conservative architecture (no reusability) and slightly longer version of Shuttle SLB's they are way way over budget (20 billion?) and very very late. They call it Senate Launch System.

I sincerely hope Starship will put an end to this.

It is my view that any mission to the moon should be tasked with starting a settlement there. Some preliminary structure for a permanent presence. How much more "research" do we need to do there?

Artemis 1 and the First Launch of NASA’s Megarocket: What to Know

NASA’s most powerful rocket is nearly ready to send an uncrewed Orion capsule on a 42-day journey to the Moon and back, but this deceptively straightforward plan involves a ton of moving parts—including a harrowing 5,000-degree reentry through Earth’s atmosphere. Here’s what you can expect from this historic mission, called Artemis 1, as NASA officially ushers in the Artemis era.

When will NASA’s SLS launch?

NASA’s Space Launch System (SLS) is scheduled to depart the Vehicle Assembly Building at Kennedy Space Center in Florida on August 18 to begin its short trek to Launch Complex 39B. Should all go according to plan, SLS, along with an uncrewed Orion capsule placed atop, will launch on August 29 during a two-hour window that starts at 8:33 a.m. ET. Backup windows are also in place for September 2 and September 5.

Thanks Baz for the info and head up on the launch. Look forward to viewing it out here on the left coast.

Thanks, Trevor! Hoping all goes well with this amazing project.

Saw your work in the aviation thread - very impressive!

$4 billion per launch and not a reusable vehicle. That's criminal IMHO.

As for why this vehicle and not the Saturn V it is my understanding that this is akin to Mercury in that it represents our first steps towards Mars. However, with everything we've learned so far this thing should have reusable components.

I didn't realize so many parts were being sourced from the old shuttle program. Fascinating!!!

Where were you in '69?

I was a nine-year-old kid and begged my dad to fill up the family barge at Gulf, even though it was a penny more a gallon, just to get this:

For the Artemis I mission, four veteran engines were selected, with a combined 25 flights between them, according to NASA:

Engine E2045: The most veteran engine with 12 flights, including a docking with Mir in 1998 and John Glenn's flight, also in 1998
Engine E2056: Four flights, including STS-109, a Hubble Telescope servicing trip and Columbia’s last successful mission
Engine E2058: Six flights, all to build the space station
Engine E2060: Three flights, most notably STS-135 Atlantis, the final shuttle mission

Will be watching in awe of what our engineers and scientists have come up with. Just like I was in awe watching the first moon landing in 1969. That's something that never leaves you, shapes your thinking of what is possible, and points you in a path - whatever that may be.

Tomorrow morning let's take pride in what our country has achieved.

Best of luck Team Artemis.

Not having cable or satellite, is there a website to watch the launch?

Should be here.
