Starship is an SLS killer
No. Cluster tanks are too heavy. Saturn I/IB was an aberration.At any rate, here is an article on potential problems in tankage draining:
Here is where cluster tankage might have advantages?
Wrong. The idea is still applicable. Need drives requirements. Why you don't understand this time after time that it has been demonstrated.For too long, there was this idea that no one “needed” anything more than a rocket that could put 20 tons up there.
A failure of vision.
Whether it flies or not, it still is an "SLS killer". Earlier Artemis is dependent on it. There is no reason for SLS without the Starship lander. Artemis 3 has no reason to fly without Starship. And once Starship is proven, then also SLS has no reason to fly,Starship has yet to successfully prove itself.

It’s so hard not to humanize robots. When the technician was trying to confuse it you are expecting the robot to react like a human would. “Hey buddy wanna stop messing with my blocks” followed by a punch to the face lol.until IFT-2 happen, let's look what happen at TESLA:
( and another Falcon 9 B1058.17 made it 17th launch and landing)

Polaris Dawn is looking like Q1-2024. It is a development program and new technology takes time to implement. The EVA suits being a big driver of the timeline.
No updates from NASA on Polaris II, but we are still hopeful we can help out Hubble. We have a great plan to extend the life and capability of the exploration platform at really no cost to the government.
Cluster tanks are too heavy.
Saturn I/IB was an aberration
Since the hardware has already been built it will fly regardless of the status of the Moon-lander.Artemis 3 has no reason to fly without Starship.
If only because, "it's cheaper to throw it in the ocean than to scrap it". The pinnacle of government efficiency.True.
It wasn't an aberration it was a result of a directive for developing a heavy launch rocket as fast as possible using as much existing off-the-shelf hardware possible to get it operational ASAP. If the production of Saturn rockets hadn't been short-sightedly curtailed then a second production run of Saturn Its would've meant a new S-IB (Call it the S-ID) using just one LOX tank and one RP-1 tank (Most likely constructed by McDonnell-Douglas based on using modified S-IVB LH2 tanks separated by an intertank section) using a single Rocketdyne F-1A rocket-motor (Likely with two LR-101 vernier rocket-motors for roll-control).

If it's useful. I don't know what applicable data they might have acquired throwing the Ares I-X in the drink.Aside from that it would also produce a LOT of data too which engineers always love to have.
The Saturn I/IB were very important step in History of Rockets.No. Cluster tanks are too heavy. Saturn I/IB was an aberration.

a. Yes, it is. it is one of the only cluster tank launch vehicles.It wasn't an aberration it was a result of a directive for developing a heavy launch rocket as fast as possible using as much existing off-the-shelf hardware possible to get it operational ASAP. If the production of Saturn rockets hadn't been short-sightedly curtailed then a second production run of Saturn Its would've meant a new S-IB (Call it the S-ID) using just one LOX tank and one RP-1 tank (Most likely constructed by McDonnell-Douglas based on using modified S-IVB LH2 tanks separated by an intertank section) using a single Rocketdyne F-1A rocket-motor (Likely with two LR-101 vernier rocket-motors for roll-control).
And do what?Since the hardware has already been built it will fly regardless of the status of the Moon-lander
not really. AA-2 was a better used for the money. And a it would not be a "live" stage with a dummy engine. Calling it that would denigrate the MD S-IV stages.The Ares I-X should've been followed by the Ares I-Y which would've been a flight-test of the five-segment along with a live second-stage (With a dummy J-2X engine) call it the S-IVC and high altitude abort test of the Orion LAS with a live Orion CM IIRC followed by the Orion 1 unmanned suborbital flight test. This would've provided more useful data for the future SLS programme even if the Aries I was cancelled.
Ares I-X provided no legitimate data that justified its existence. the money could have funded a Discovery class science mission.
And do what?
Huh? Do you understand the concept of cost?If he swallows his pride, send up a slew of Starlinks stop SLS.
Artemis II does that. No need to repeat it. Photos wouldn't be worth the effort. No money for a science package.Fly around the Moon, take photographs and perhaps instead of a Moon-lander some sort of science-instrument package for Artemis II to dock to and do some science observations of Moon plus a long duration trip along the lines of Apollo 7 to test out the spacecraft's capabilities.
Falcon did not upsurped, NASA gave it away. Plus it is a Starship pad.Had Falcon Heavy not usurped one of the shuttle pads, two SLS lunar missions could do LOR.
One with Alpaca.
But this is a SpaceX thread.
SLS employees a lot of folk--so that is outreach. If Starship does work, Musk may use a lot of those workers at some point.
If he swallows his pride, send up a slew of Starlinks stop SLS.
Artemis II does that.
No need to repeat it. Photos wouldn't be worth the effort.
No money for a science package.
a. Because it is not worth the cost. No sense in throwing more money at bad moneyIf there's no lander available in time they'll still fly so why not do extensive photography also in that case NASA could do a long-duration deep-space flight ala Apollo 7 to test the Orion spacecraft's endurance.
No such instruments exist. That was from days of building and flying multiple spacecraft to the same destination in the same launch period. Nobody makes spare parts, especially instrument or has the money for it. Magellan was an exception because there was no instruments, just a radar which is a radio and it used a spare antenna.Nothing new just cobble together something from spare off-the-shelf sensors leftover from other space-probes (This is how the Magellan Venus-probe was built for example).
Typo?SpaceX has no need for SLS workers. Plus they won't like SpaceX work ethnic
b. Artemis 2 is already 10 days, no need to test the duration
Handhelds are not going to provide any better
No such instruments exist.
also, there is no spare human rated structure for such a platform.
1. Just no. Instruments have been gathering that data for decades. No need for human guinea pigs.1. There is actually something useful you can gather from another long duration mission - medical data. While in the decades starting in the early 1970s there has been a LOT of long term medical data concerning the long-term effects of weightlessness (And elevated background radiation) on the human-body courtesy of Skylab, the Salyut space-stations, Mir and the ISS by the Soviet space=programme, NASA, ESA and Roscosmos but that information deals with the relatively benign LEO environment deep inside Earth's magnetosphere which blocks out a lot of the more damaging radiation. The data subset dealing with prolonged exposure to the deep-space environment (Well outside of Earth's magnetosphere where the astronauts got exposed to all of the Sun's ionising radiation place galactic background radiation and cosmic-rays) is much more limited, it consists solely of the medical obtained from NASA astronaut from the Apollo 8,10-17 missions. Artemis II of course will add to that but then so would Artemis III.
2. If an Artemis CSM is being sent why waste the opportunity.
3. Maybe there are no spare off-the-shelf scientific instruments leftover from previous science-probes there are of course off-the-shelf designs which additional copies could be made and suitably adapted.
4. Who said anything about a human-rated platform? A modified Comsat bus could be used but if you do need a human-rated platform that can be used with
5. suitable modifications there's the Northrop-Griumman Cygnus spacecraft
6.and of course there's the Lunar Gateway variant which would with modifications could be used.
They have beat them 7 times. But Tuscaloosa doesn't matter. The waste is in Huntsville.Longhorns beat Bama once--not enough for Jim.
SpaceX positioned Ship 25 for stacking as they prep for Starship's second integrated test flight. The hot stage ring was also installed again after crews completed work on the upper section of the booster.
Link:
The first integrated test flight of Starship lasted just under 4 minutes before the flight termination system activated and destroyed both the booster and upper stage. This cut the flight test short, however, the vehicle had managed to clear the pad and provide minutes of invaluable flight data to teams at SpaceX. It also revealed a few problems that would need to be addressed before the next attempt.
This leads us to today as a new booster and upper stage are stacked on the launch pad patiently waiting for FAA approval. This being said, in the time since the last flight, changes have been made to every aspect of the launch process. This includes Stage 0 infrastructure, physical test article upgrades, new hardware, and even alterations to the flight profile.
On that first flight, one of the biggest mission objectives was successfully completing stage separation. While the vehicle couldn’t complete that mission event, SpaceX is confident this time around things will be different. Here I will go more in-depth into all these changes, what SpaceX learned between the first flight and now, how much longer until FAA approval, and more.

No. Why? There is no reason for it.Something I was wondering about.
Let's say you stretched SuperHeavy out and put heat shields on it.
Would the weight of TPS on one side counterbalance a Buran type Shuttle 2 on the other?
Tankage and engines land separate from the spaceplane...several of which could be left in orbit?
No need for a spaceplane and a StarshipWe will call it Dreamchaser then.
You say there is no need of a spaceplane in orbit.
Still, if the bulk of a launch vehicle (tankage and what-not) lands on its own...the orbiter is more agile, yes?
I'm not saying don't use Starship.
For Moon and Mars that's fine.
For LEO...just maybe a stretch SuperHeavy with a compact piggyback package offers passengers a little less risk.
I like orbiters that aren't eggshell tanks.
What is the point of agility?
Anyways, passengers aren't going to be returning on Starship until it has done dozens, scores or even hundreds of landings.
1. No need to get people flying "early" on Starship, they have Dragon1. Getting people flying early is what a spaceplane can get you.
Now, how did Falcon iterate as fast as it did?
2. Thanks to engine-out (which I recall you pooh-poohed at NSF), the payload on Falcons got where it needed to go…leaving SpaceX to fool around with the cores on return.
That’s the path I’m advocating.
Top-mount, side mount…whatever
3. Just make sure a known thing like an orbiter gets up there, with a TPS equipped stretch SuperHeavy doing all the risky stunts on return.
4. STS didn’t need its ET to get back, Jim…that’s the point.
1. No need to get people flying "early" on Starship, they have Dragon
2. Wrong again, your reality is not shared with the rest of us. Low cost is what got SpaceX to fool around with cores. They could fly small payloads and have excess performance to work on reusability. It has nothing to do with engine out. And nor I did poo-poo engine out.
3. No need for a thing like an "orbiter".
4. That is one of the reasons the STS is no longer around. Reusability.
You still don't get it. The driver is cost. Not "coolness", looks, thrust, or size. Just the cost to put payload into orbit is what is driving Starship.
You still don't get it. Costs are everything when it comes to spaceflight other than that which is gov't funded. If costs aren't reduced, nobody is going to spend money on going beyond earth orbit.Since you go on and on about costs, I’ll remind you that the F-35 program has a lot more to be spent on it than SLS, or a simpler spaceplane that has jets but no SSMEs for that matter..1.5 trillion dollar total life cycle cost for something that can no more shoot down a Nork ICBM than my pellet rifle. Go critique that for a change.
Someone might do a less costly orbiter.
Dream Chaser for now—maybe something more substantial down the road. Don’t you work for Boeing?
