Going back to the moon......Artemis I......

They said there was a 8" fuel line leaking . An 8" fuel line!

[fisher22]

Yes, as I understand it:
They believe the seal in the fuel line coupling didn't seat properly, and instead of simply disconnecting/reconnecting it, they will replace the entire line. They just don't do things like we do with our cars.

They're using bits of Shuttle technology.

This launch uses four Shuttle engines and the boosters are Shuttle with a segment added.

Thats the first stage. I'm not sure what second stage uses.

In addition to the improved rocket technology itself, there has been a good amount of residential/business development around what was undeveloped land surrounding Cape Canaveral since the Apollo program ended. So, using a less efficient (1960s design) Saturn V rocket would result in earthquake-like damage to the new communities.

Having said that, if you are anywhere near Cape Canaveral, interested, and even somewhat patriotic, by all means take the tour and see what the US accomplished at the peak of space competition. It will blow you away. I went with my dad, who was only mildly interested, and we both came away with new pride and respect for the sheer magnitude of the project.

Things on our cars don't go from ambient to
minus 423 degrees Fahrenheit in 2 seconds.
But I'm sure it's nothing that several million dollars can't fix

So apparently just getting a bigger Crescent wrench and giving that fitting one more 1/4 turn didn't do it?

As private companies compete and drive down costs, the agency tries to use expensive refurbished rockets from the space-shuttle program to go to the moon.

$240 to every taxpayer for this rocket. $960 for this household.

We should at least get a moonrock.

Thank-you, I really appreciate it. You can rightly be proud of what you've accomplished. Sincerely, please pass my thanks on to everyone in your household who has contributed.

When you put it that way, it kind of sounds like a bargain. We’ll get moon rocks, but more importantly we’ll establish a permanent presence similar to the ISS. Why, you ask? In addition to continued science and exploration:

1. Let’s start with China. When it serves them to follow international space treaty, they will use it against us and the other space-faring nations (although mostly they don’t abide). They plan to have their own permanent presence, which will then allow them to occupy, then “own” portions of the moon, complete with drilling and mineral rights. Not to mention the security aspects of a foe nation having a vantage point over us.

2. To create a launching point for Mars missions. It’s much easier to start a trip to Mars from the reduced gravity of the moon then to launch direct from Earth. The plan is to launch pre-fabricated pieces of a future Mars spacecraft from Earth, then assemble them on the moon.

If 1 and 2 sound absolutely crazy, or at the very least make you say “What the heck for?” then there’s a lot more to talk about. But in the meantime, watch a few episodes of Steve Carell’s comedy “Space Force” on Netflix. It addresses the situation pretty well for a silly comedy.

Didn't mean to be negative, perhaps a little sarcastic, sorry. When I see large numbers, I put it in perspective. But I would love a moon rock. Or a tiny pebble. Hell, I'd settle for a spec of dust.

The United States spent $25.8 billion on Project Apollo between 1960 and 1973, or approximately $257 billion when adjusted for inflation to 2020 dollars. Adding Project Gemini and the robotic lunar program, both of which enabled Apollo, the U.S. spent a total of $28 billion ($280 billion adjusted).

Considering we're 30ish billion into Artemis, (1/10 adjusted Apollo) this seems like a bargain.....

SpaceX just shot another off.....51 more satellites!

A SpaceX Falcon 9 rocket will launch with another 51 Starlink internet satellites at 10:09 p.m. EDT (0209 GMT) tonight. This mission will also carry Spaceflight’s propulsive Sherpa-LTC2 space tug, which will climb into a higher orbit with Boeing’s Varuna Technology Demonstration Mission, a pathfinder for a planned constellation of broadband satellites. The Falcon 9’s first stage booster will land on a drone ship in the Atlantic Ocean.

[Esel Mann]

Also an additional orbital payload too!
It was awesome as always to see. Plus the 1st stage coming back to land on the ocean pad. Kool!
I tried to take pix. Sadly they are of a quality such that I'd be accused of one or more of the following:
-the guy who photographs samsquanch sitings.
-the guy who photographs ufos.
-the guy who bought byrons old cell phone on craigslist.....

If it were a good idea, they could fund it
with donations and voluntary contributions.
But it isn't.

They also found a 10 mm socket that had rolled under the rocket.....

Very few people would be willing to do that.

The correlation between voluntary donations and something being a good idea doesn’t exist. You couldn’t get the masses to effectively donate enough to end hunger in the world.

[red 928]

yes, I could
if it were possible

Elon Musk donated around $5.74 billion to charity in November, just weeks after tweeting that if the UN World Food Program showed him how $6 billion would solve world hunger, he would “sell Tesla stock right now and do it.”

It’s unclear, however, where Musk will be donating that $5.74 billion. Musk sold 5,044,000 Tesla shares worth that amount and gave the money to charity between Nov. 19 and Nov. 29, according to an SEC filing. The recipient is anonymous.

This massive donation to an undisclosed charity came just weeks after executive director of the World Food Program David Beasley told CNN on Oct. 26 that the world’s elite needed to “step up” to end global food insecurity, specifically citing Elon Musk and Jeff Bezos. Beasley said that “$6 billion [would] help 42 million people that are literally going to die if we don’t reach them. It’s not complicated.”
