Home Forums Hunting & Shooting Hunter's Campfire NASA's big launch

Update:

Artemis 1 is currently scheduled to launch no earlier than Saturday, Sept. 3, at 2:17 p.m. EDT (1817 GMT) from Launch Complex 39B at NASA's Kennedy Space Center in Florida.

Update: Weather is forecast to be good. Fueling is underway but there's a hydrogen leak. They're troubleshooting it. The launch window is two hours starting at 2:17 pm Eastern. Live coverage starts at 12:15 Eastern HERE

Hydrogen leak.. What could go wrong....
At least it is unmanned like the white house.

No go for launch today, Saturday.

These private rocket guys don’t seem to have the same problems NASA has
Getting a rocket off the ground, and back. Too much govt. involvement? Too many govt. engineers? I think I would be very hesitant to get on a NASA rocket.

Musk would have already set up a colony on the Moon.

Obama's solution would be to UBER our way into space via Russia but we can't talk about that any more.

Three little words- - - - - -"Low Bid Parts"!

I don't know if they can get at the area where the leak happened while still at the pad- or if they have to roll back to the VAB again. We'll see.

11yrs of tax payer funding for multiple scrubs due to mech issues.
Which is not a bad thing safety wise..
But not speaking to well of design and or assembly.

Our lull in Nasa,s manned program is causing a exspensive catch up game....


But that is all versus what that same 11yrs of what private companies have done.

NASA is a .gov money pit....

Moonshot Rocket launch.....its a dud

All parts of government are just money pits to laundry money.

Lot of $$ to keep the Trekkies entertained.

It's already four years and billions of dollars late.

SpaceX: 500 employees

NASA Houston: 30,000 employees

Anyone notice how much that Artemis looks like the Saturn V and not like the Space Shuttle?

Good read.

Just to clear up a couple technical points. Artemis is not the rocket. Artemis is like saying Apollo. The rocket is called SLS, Space Launch System and it is basically a bit and pieces deal from the Shuttle. The liquid fuel engines on the bottom are the RS 25 engines from the Shuttle but there are four instead of three of them. The solid rocket boosters re from the Shuttle except they are 5 instead of 4 segments. The solid propellent is shaped to increase the burn rate so they will still stop at about 120 seconds but the faster burn rate increases thrust.

The thrusts that are listed are not comparable to a rocket like the Saturn V. The five F1 engines on the Saturn V gave about 7.9 million pounds of thrust from Apollo 15 on. On all Saturn Vs the thrust was maintained until about 2 minutes and 15 seconds when the centre F1 engine was shut down. This was to limit G forces to 4 Gs. The Space shuttle solid boosters starting reducing thrust almost straight away and by 1 minute 30 seconds thrust is down to about a half and this all to limit G forces to 3Gs. The initial thrust of the shuttle in relation to the launch weigh was far higher than any other rocker and you will notice how quickly it gets away. What really counts in total impulse which is thrust by time. The new SLS is a bit bigger than the Saturn V was. SLS will put about 150 tons into low earth orbit whereas the Saturn V was about 140 tons. The shuttle was only about 25 tons but that was because the shuttle itself was also being put in orbit. If you take the bare weight of the Shuttle at about 75 tons and replace it with payload then the Shuttle would have put close to 100 tons into low earth orbit, much less than the Saturn V or SLS.

The Falcon Heavy thrust at lift off is not a true indicator of what it will orbit. The Falcon is limited because it does not use liquid oxygen and liquid hydrogen for its upper stages, is liquid oxygen and kerosene all the way. In short, when it comes to the weight you can put in orbit the Saturn V and the SLS are way out in front of any other launch system.

I hate to be petty but you a Cuck

The post-scrub news conference said that they now cannot try again until at least Sept 19 and probably not until October. The launch window depends on the positions of the earth and moon orbits. It is likely that they'll have to roll back to the VAB to do work and more tests. In another complication, there are 10 scientific cubesats mounted inside the rocket which were to be deployed near the moon. But most of them are not connected to power supplies and their batteries may be dead by the time of launch. They can't be accessed unless the vehicle is destacked.

There's a SpaceX launch set for tonight, and I'll make a separate post about that later today.
