Yes, the safe exclusion zone will probably have to be 14-20 miles to prevent bystanders from suffering permanent hearing damage. Even at that distance the level of sound would be equivalent to standing next to a freight train while it's horn is on full blast.
An 18m ship would have to be substantially more than twice as powerful to lift itself, because the mass of it's propellant will be much more than twice that of it's 9m predecessor. At that point you'd likely need the engine equivalent of 20-30 F1's worth of thrust or about 200MN. The sound of an 18M Starship takeoff would require likely more than fifty miles exclusion, and thus it would be highly impractical to fly it from the coasts. Also it goes without saying that accidentally popping an 18m starship prototype would be the equivalent of setting off a small atomic bomb.

Luckily, oil rig platforms are actually quite cheap to establish, since all of their technology is completely conventional. They can hold some absolutely enormous weights with ease, more than sufficient that you'd probably run into engineering problems designing a rocket before you run into the weight constraints of your launch platform. They can be reenforced to shrug off hurricane force winds with ease, and I'm certain that the specific requirements of a flame director trench can easily be implemented if the platform is built with it in mind.
Since it's easy to build heavy things to sit in the ocean it can be overbuilt essentially as much as is necessary for any project.
Some of the largest heaviest platforms in the world also only cost in the 50-100 million dollar range, so the expendature to build a sea launch platform for superheavy rockets wouldn't be far outside of the normal cost of a singe Falcon Heavy/Atlas-V/Delta launch.

It's not just latency to the nearest exchange, it's latency all around the world and you can't build a microwave relay for that. They have to react to every piece of relevant news and trade off of it. They have buy and sell from different exchanges located thousands of miles away, across oceans. It has been estimated that single millisecond advantage could mean an additional 100 million a year to some high-frequency trading firms.

SpaceX is hoping to work out the finer engineering challenges with these "flying grain silo" prototypes within a couple of years, where it would take many years to a decade to work out via smaller scale testing and studies (ex: SLS). They're like the Grasshopper but scaled up.

4ASS Director of Mad Science reporting. I'm bulk ordering mylar, structural supports, and light sources to test better shapes for seeing if I can build a quantized inertia drive. If that doesn't work I'm going to see if I can at least use optical resonance to make solar sails more effective than flat shapes. Starship means not everything has to origami into hyper compact launch configurations anymore so I figure something more than a flat sail could show improvements.

Does the bathymetry of the GOM allow a condeep? Looks like it falls away reasonably quickly. Tallest condeep I could find is 300m. Is there 300m or less deep water near enough shore taking into account how far offshore it will need to be? Also worth bearing in mind that that single platform would be doing serious duty if it was the only one. And they are not cheap. Troll A was $650m in the 90s.

I was in the metal part of it, but the interesting part of them is that they allow for so much more load bearing than a pure metal rig does due to how they work. I'm not thinking build new, but if they could repurpose old ones, that would be an interesting thing to look into. Would allow for storing propellant in the legs as well.

I believe they stagger the drops so that they can maintain x G acceleration better. Dropping off all at the same time would give it a bit of a jolt that may not be desirable. Because they light them all at launch and they don't burn differently. They all burn out at the same time.

Thunderf00t likes to criticize the kinds of companies where they promise some kind of advanced tech to gather money before disappearing without delivering a product. Before some of his well known companies got really successful, Elon would've seemed to be starting companies like that. So I think that's where the initial hate came from.

Reminder that SpaceX got started in satellites via its purchase in 2005 of 10% of Surrey Satellite Technology Limited, a pioneering British satellite company based in Guildford, Surrey. I think it's highly likely there is British IP or derivative thereof in Starlink satellites.

'During June 2004, American private space company SpaceX arranged to acquire a 10% stake in SSTL from Surrey University; speaking on the purchase, Elon Musk stated: "SSTL is a high-quality company that is probably the world leader in small satellites. We look at this as more a case of similar corporate cultures getting together"'

SSTL are a scrappy disruptive startup that dramatically lowered the cost of production in their industry via an innovative approach developed by a highly intelligent technical visionary, who wasn't afraid of thinking outside the box. Remind you of anyone?

Falcon Heavy was supposed to do it too, but they found it to be too much of a headache to figure out. They settled on throttling down the center core and letting the side cores down the heavy lifting first, then when they let off, throttle up the center instead. Less payload, less headache though.

These are serious prototypes.
They just don't add unneccessary parts when they still don't know if it'll explode yet. No point in adding a nose that isn't needed yet because the tests don't go fast enough. No point in adding fins when the tests don't go high enough. No point in adding additional engines as long as the tests don't move enough mass.
Sure, they could've made every single one of these look like MK1 at the presentation. But then they would've looked extremely fucking stupid as most of them just kept disintegrating.

The furthest I can get is to have people try out KSP for around 20 hours, then they never touch it again saying it was boring. Hopefully 2 will make introduction easier and add fun with the multiplayer stuff planned.

Spacex needs a shitton of refueling flights for each moon landing. i think zubrin calculated that they would need up to 20 launches in total for each mission. even if they would need just 10 that would still be insane. not as insane as the 3 launch lander from the national team, but it would still make the dynetics one the obvious choice, as long as you don't want to land really heavy payloads on the moon of course.

Well starship with 50 tons of cargo and a full tank has 7.7 or so km/s of delta V.

Trans lunar injection is 3.2 Km/s, and a direct landing is 2.5 km/s. That’s 5.7 km/s. A direct ascent to Earth is 2.5 km/s. An earth landing is 0.5 km/s.

Total Delta V is 8.7 km/s, and remember that even a tanks full Starship with 50 tons of cargo has 7.7 km/s only. Also it takes 12 launches to refuel a starship.

Because those particular people have been stunted too badly by modernity to have self motivation anymore. A normal person would look at somebody who is superior to themselves in something and feel motivated to achieve that same level. They'd want to work more at a better job so they could have the guy across the street's car, or go rearrange their schedule to hit the gym so they can tone up. Nowadays you can barely even get a person to do work at all without an endless amount of bitching and moaning, and instead of wanting to buy a car better than chad's, they'll just find an excuse to start a riot and steal chad's car. Instead of hitting the gym to get chads muscles they'll just complain about chad on twitter and try to get him fired.

Yes and no. I only had a very surface level appreciation for rockets and spaceflight until I found KSP back in 2011. The same kind of "oh, cool" and that's it reaction. I did have a general interest in scifi though.
Playing KSP made me learn the physics and such which gave me a much greater appreciation for real spaceflight and piqued my interest dramatically.

Yeah but in theory a fast response vehicle means something ready to launch at all time (like an ICBM) and they say they want to put or retrieve things/people in orbit so basically if you build your first stage around a SRB Ares style you spare yourself a lot of headache.

It depends what you mean by "serious prototypes". If all you care about if getting to orbit with little to no payload, they could strap one of their many spare nosecones on SN5, add two more Raptors to the existing thrust puck and they could likely get to orbit (or close).

If you're talking about the full Superheavy/Starship stack with landing, that'll take longer but they aren't too far off. Right now the biggest hurdles appear to be getting the heat shield mounting mechanism down (which they are actively doing tests on), getting the aero surfaces installed and doing test flights (which should start with SN8 after a handful more short hops, probably a couple months), and then building Superheavy.

Once the high bay is done the only real new work that needs to be done on SH is the thrust puck design. It's not trivial, but at least early on they could over design it to handle loads and get a heavier-than-necessary version flying, then tweak it down the road. At that point the hold up will just be getting enough Raptors to actually fully kit the whole thing out. We know that they should have a bit of a stockpile already, and if it winds up being a bottleneck they could probably do test launches with a half-fueled booster and less than the maximum number of engines.

If they want to get to orbit by any means necessary, they could probably get a SH/SS full stack flying by early next year. If they want to do it right with all the bells and whistles, then I'd guess mid/late 2021. A lot of it depends on how quickly they can start turning around test vehicles and whether or not they have any more major RUDs that destroy the launch mount.

I believe that it's just because it's easier to scale up than it is to scale down. 9m is probably the minimum size to guarantee they hit 100t+ payload capacity as well as all of the necessary reusability components. No reason to break the bank on a 12-18m ship when you can do all the prototyping and R&D work on something that requires less than half the material costs.

Apparently the blast wave profile changes based on how dense the source is so I'm not sure we can approximate how bad it would be even if we know how much energy is being released. It could be that the damage is typically overstated, the N1 site still had a bunch of structures standing after the explosion based on the shitty image I just looked at.

i highly doubt that. one year is far too optimistic for orbital flight. remember that during the entire last year they went from one hop to another hop with a better and more advanced vehicle. still there will be many setbacks and probably explosions to watch until superheavy makes a succesful flight

This. While I think Starship will fly “soon”, I’m betting on 2022. Simply because Superheavy has yet to fly or even be stacked, let alone hopped. I think Starship is done enough to go orbital though I mean even three sea level engines would suffice.

Also apparently SLS has to launch within a year or else they redo a bunch of the work.

I mean something like this but put it on an upper stage so you can return it to earth after its done
or alternatively put a heatshield under the payload mount, so you just throw away the mount instead of the whole thing and do a flip around for landing after reentry
maybe an inflatable heatshield to make sure its big enough to protect the sides of the stage during reentry

Dragon doesn't carry a service module, it carries a trunk with a lot of empty space for cargo. Now if they did add some tanks in there with some propulsion, RCS and spare life support equipment then it would be a proper SM. That is at least one advantage the Orion has over it, however that evaporates when the EUS isn't present, because then Orion's endurance is only a fraction of Dragon's, and it hasn't got any real significant advantages left over.

>The MHV guidance system solely tracked targets in the field of view of the infrared sensor, but did not determine altitude, attitude, or range to the target. Direct Proportional Line of Sight guidance used information from the detector to maneuver and null out any line-of-sight change. A Bang-bang control system was used to fire 56 full charge "divert" and lower thrust 8 half charge "end-game" solid rocket motors arranged around the circumference of the MHV. The half charge 8 "end-game" motors were used to perform finer trajectory adjustments just prior to intercepting the target satellite. Four pods at the rear of the MHV contained small attitude control rocket motors. These motors were used to damp off center rotation by the MHV.[12]

the Soviets did this because they were that convince what the Americans were trying to do was impossible
the Americans did this because they were convinced that what the Soviets were trying to do was impossible
the Americans ended up with really good upper stage engines that enabled smaller vehicles to launch high energy missions (because you got more lift out of a lighter stage with hydrogen)
the Soviets built the best booster engines anybody had ever seen but had their economy collapse before they got anything good off the ground and now you're doing magical thinking and attributing supernatural qualities to the Soviet engines

Not for several weeks, probably. First they need to make sure it doesn't leak. Then they need to make sure it can hold together in cryogenic conditions. Then they need to refit it with a raptor and some ballast (or just slap more fuel into it). Finally, they need to test fire it, and then they need to fly it. Before any of that, they need approval from the FAA for anything that can make it explode.
