Funny you should ask that, a particularly spicy L2 post about Blue Origin dropped last week: they are currently building a large painting facility at their Florida factory (Elon really got it right with the stainless, no need for painting) and apparently it’s sized to fit New Armstrong as well as NG. Now this all sounds great, but the same post also revealed that they haven’t even begun construction of a ‘pathfinder’ prototype stage for New Glenn yet and are still setting up welding machinery. Methinks they should focus on getting stuff flying before thinking about future rockets...

They probably see the writing on the wall with Starship, and they'd like to jump on that bandwagon before it's been flying for a few years and the market is being cornered. However, they're still obligated to fly NG and NS.

I doubt even active could hold up such an enormous and lopsided structure. I get why artists have to take liberties though, if it were portrayed realistically you wouldn't see much more or less than a very thin silver/white thread which at the distance of the observer wouldn't be very interesting. By far the largest part of any realistic space elevator will be it's counterweight anchor which pulls the whole thing taut, estimated between 1-5 megatons in weight at a minimum for an Earth elevator, depending on the type of tether material you're using. At least all you'd need is a big stack of moon-concrete or some other easily sourced material, if you really do use moon concrete you'd need a cube of it about about 2080m^3 in volume to anchor an elevator on the heavier side, something that used say Twaron or T1100G Carbon Fiber as opposed to the ideal but unrealized nanotubes or graphene. So what you'd see is a long reflective or white fiber with a huge grey brick at one end and a little clump of stations (little compared to the overall structure) much closer to the brick than to the planet.

The taper ratio for Twaron and T1100G carbon fiber isn't great. The breaking lengths of those are less than 500 km. Colossal carbon tubes have a reasonable taper ratio. Remember: 30 MegaYuris or bust! (Yuri is a unit of specific strength in newton/(kg/m)) 30 MY is the lower limit for a practical space elevator so you really need more.

NA is going to be Nova sized, mark my words. At this point I wouldn't be surprised if NG ends up being barely more than a hopper testbed for NA.

Bezos may be a little cringe with his pacing, but unlike Musk, he also doesn't really need any of this to actually make him money, so he's going to build what he wants, when he wants to build it.

Looking at his interest in the F-1, part of me wonders if he isn't working on a methalox-burning F-1 class engine to power NA. Imagine a cluster of 7-12 of those fuckers powering a big chungus NA 1st stage.

orbital rings are retarded. They require an insane amount of materials to build and you have to pay the 'keep the structure from falling down' tax for as long as its up. The only reason space elevators have been considered at all recently is that carbon nanotubes could allow us to build space elevators with reasonable amounts of material. Also, the orbital rings we can actually build may not be stable. Also Lofstrom loop is definitely not stable and Lofstrom's response to dealing with this is 'LOL COMPUTERS.'

Why bother with the giant useless counter weight when you can extend your tether far beyond GEO until the centripetal force pulling on the far end is enough to counterbalance the Earth's gravity pulling on the near end? That way not only do you 'only' need to build more cable instead of launching a brazillion to concrete block or grabbing an asteroid at great expense, you can also climb the cable all the way to the end once it's built and just by letting go you can get flung onto a higher-than-escape trajectory towards other planets effectively for free.

If BO had the ability to improve the BE-4 until it had the same chamber pressure as Raptor it'd pretty much be F-1 class to begin with. BE-4 has what, like four times the exit area of Raptor? Given an equal chamber pressure that'd put it in the ballpark of 4x as powerful, eg 8000 kN.

Move the canards up by 10-15 feet and extend those fin fairings over the pressurizing plumbing raceways until they become aerodynamically faired chines like the space shuttle's wing roots and that schematic is spot on.

The legs will be F9 style, and when closed will be covered by some sort of TPS that does double duty to shield them from the heat of the raptors on landing.

I wonder why other agencies are so cautious towards reuse. Is it because it needs a high flight rate to be viable and there's doubts that such rates can be done? Is it because the Shuttle left a bad taste for reuse? Or is it just because most payloads are so expensive that the cost of an expendable launch vehicle is tiny in comparison?

One of their ideas I think was fly just the rocket motor back not the whole stage, since the motor is the most valuable part and thus worth saving, whereas sod the rest of the stage, its relatively cheap to replace.

I guess that extra cable is probably more expensive than some moon bricc, since establishing bases on the moon is useful for a lot of shit it wouldn't be an enormous extra imposition to add a concrete mixer, a small excavator to scoop up dirt, and strap that shit to a small booster. Another popular iteration is to just build the elevator on the Moon since it only needs to be a fraction as strong to operate there, although that also means you'll want quite a huge moon operation to actually feed the elevator people, ships, and supplies to transport to other parts of the solar system.

A long time ago, America gave an aerospace contract to an unready contractor for the purpose of protecting jobs. The contract was delayed, overbudget, and underperforming.

This was the Brewster Buffalo. Hundreds of American pilots died because it was hot trash.

Do HTS even have a high enough critical current to support skycranes? There is also still drag on an orbital ring even with superconductors. The ring itself uses non superconducting aluminum and there will also be some dissipation due to elastic deformation of the ring.

In spite of being very shiny it's refractive index in the visible spectrum is pretty low at least compared to stainless, 1.37 compared to stainless' 2.7 (both measured at 632nm), so while it would be very useful purely to get blasted by heat and not melt, it's not so good for passively reflecting away anything but infrared radiation, it's great at that though, around 800+nm it's refractivity spikes to 3.8+ while it's nearly transparent to UV at a refractivity of only 1.04.

At best, its an ever increasing technological race where the end is mars colonization and solar system exploration with very large but cheap rockets.

Today, Soyuz MS-15 has been put on the launchpad for launch at September the 25th which is two days from now. MS-15 takes expedition 61/62 to the ISS and is the last launch of the Soyuz-FG variant of Soyuz rockets.

With the last launch of the Soyuz-FG, is also the last of the Soyuz-U legacy (The most launched variant of Soyuz rockets standing at 786 launches) that is going with it. The FG variant will have had 70 launches, including MS-15.

Rollout and installation of MS-15: https://www.youtube.com/watch?v=HJp5Jg-Xm-k

From here on out, only Soyuz 2 will launch and will be in service untill at least 2033 with a pair of launches planned in that year, making the R-7 family of rockets 77 years old (Currently, 63).

Not really spaceflight but I found a good explanation for the Fermi Paradox (no gay filter).
-When complex/intelligent appears it quickly advances to spaxe travel capability.
-It then quickly conquers it's galaxy within 100.000-1.000.000 years. Because this is an astronomically small timeframe, it is unlikely for two cicilization to emerge in the same galaxy, more likely one will conquer the galaxy first and the second one will never exist or be part of a civilization from the beginning
-A cicilization expands to other galaxies their speed of expansion is something like 0.99c. This means that as soon as you would be able to notice their existence, they are already there.
To summarize, the reason we dont see any effects of aliens is that if we could see them, the aliens would already be here/have been here for a long time.

They don't have a vision to expand space flight operations. So they think all they need is a medium sized launcher that can launch satellites if America and Russia shut down their launch services or something.
Well that and jobs. Someone give him the quote.
Basically, it's something like: if their engineers build reusable rockets, they'd build one rocket in a month and then be unemployed for the other 11 months of the year.

It's all about vision. Europe has no ambitions to build anything in orbit and especially not in outer space either. So their space agency doesn't have any deadlines or drive to develop anything. And even if they wanted to, funding is pretty moderate anyway as well.

My spin on it is that faster then light is really hard, so hard that most races are locked up in their own solar system and the few other close by.
Many end up killing themselfs, some build their own dysonsphere, upload themselfs in to the system, spending the rest of their immortal life in ignorant bliss in the many virtual worlds they created until their sun goes supernova.

What I really like about using these is that my engine can be fully welded now instead of having parts that must thread together for the silver-based ignition system. Assuming the welds are good, this would make the engine much stronger and therefore safer. The hard part now is to find a friend of a friend who can weld for me.

So one city police pension fund shareholder is suing SpaceX for the acquisition of Solar City. Vast majority of the SpaceX shareholders voted (85%) in favor of acquisition after an independent financial advisors weighted 4 other solar companies and found Solar City to be the best choice. Musk had to recuse himself from the voting due to being involved, however still voiced his opinions. So that's probably why they're suing. SpaceX will probably buy out this pension fund's share (however amount) and sell it to another if they haven't already.

The last time one was made it's TWR was a bit lower, but not sufficiently low to make them unusable in clusters. It should also be noted that they were still using mostly conventional materials and more primitive modeling and manufacturing techniques which resulted in an engine probably substantially overbuilt compared to the ideal. These days you'd build the basics in a powerful 3D modeler, feed in it's fuel types, mass flow rates, etc and run a complex simulation which will tell you all kinds of things like peak stresses, peak temperatures, and any combustion instability. Then you run the thing through an iterative improvement program which slightly tweaks the design towards ideal optimal parameters you set (tell it to minimize heating of surfaces, minimize structural stress, cut wasted mass, etc) and then these days you'd have as many parts as possible additively manufactured, you could make some of the heavier metal parts partially hollow with such a process without compromising their structural durability (infact, hollow honeycombed components aught to be more sturdy) while substantially cutting down on their weight. I can't for the life of me find out what it was made of, but it looks like normal steel which is greatly suboptimal when it comes to temperature control which has always been the issue with aerospikes and why XRS-2200 was so heavy. You could dramatically reduce the thickness of the wedge wall and include cryocooling channels as is done in the RS25 and an increasing number of new rocket engines, or make it out of a much more heat tolerant metal like Hastelloy-X or Inconel, or coat it with a thin layer of some high temperature cermet like halfnium carbide which is meant specifically to cope with prolonged exposure to extremely high temperatures.

YBCO apparently has really high specs in every performance aspect, you'd have to make a shitton of it though. There's still some drag and losses due to flexing but not having to power the magnetic field (a superconducting coil can carry a current forever with no losses, generating a magnetic field just like an extremely powerful permanent magnet) is still a huge advantage compared to needing to supply that force via a non superconducting magnet. IIRC the concept of an orbital ring is such that the outer ring doesn't move with respect to the ground (it's tied down with tethers, which are also the elevator cables you use to climb into vacuum), and the inside of the ring isn't solid, it's just a stream of mass affected by a magnetic field. The matter inside the ring/tube needs to go fast enough that the centripetal force as it tries to follow a straight path away from Earth is strong enough to hold up the static parts of the ring trying to fall down. If a ring's mass is mostly this material stream, then the material inside only needs to move a bit faster than normal LEO velocity, if the static ring's mass is much greater than the internal stream mass then the stream needs to move at incredibly high speeds, dozens or even hundreds of times normal LEO velocity. I'd assume that the faster the stream, the more difficult to control, but the heavier the stream the more difficult to build, so it'd be a trade off. Once the ring is set up and tethered down it should be mostly stable, you can also yank on the ground tethers for cancelling out propagating instabilities if necessary, which is much nicer than having to put rocket engines every few hundred meters and supply them with propellant.

Reflecting infrared is exactly what you want on the leeward side of a spacecraft. You only need/want high emissivity on the windward side of a spacecraft because most of the incoming heat flux is convective, that is to say the air gets really hot and touches the skin. On the LEEWARD side however, almost 100% of the heat flux is radiative, eg visible and infrared light, coming from the glowing hot plasma behind the spacecraft. On the leeward side of a spacecraft, if your surface is highly reflective to infrared and visible light, it simply doesn't get hot in the first place (or at least for steel, doesn't get hot enough to matter; aluminum is both not reflective enough and not temperature resistant enough for this to work).

You don't have to go faster than light to colonize an entire galaxy in less than a million years.
Once you first go multiplanetary you start developing better and better propulsion systems and going further and further (because muh travel time muh space rocks), and eventually you go interstellar. Eventually you develop the best practical propulsion system that can exist, at which point you can probably pull off at least 5% light speed interstellar cruise. Once you can do that your expansion front becomes about as fast as the time it takes once of your 5% c ships to cross to the most distant point in your galaxy. The time scale required to go from your first interplanetary probe to the biggest and fastest possible generation ships launching constantly in swarms of several thousand ships each is negligible on the time scale of the universe.

I dunno the specifics but it's one of the major drawbacks of aerospikes. Something about the flow dynamics of the air stream messing with the aerospike effect, resulting in less columnated exhaust and a significantly reduced Isp, and since we're reducing Isp but not changing propellant mass flow the thrust therefore goes down.

How long does it take to weld together a 9m wide 55 m long barrel, a week? Less? They want multiple Raptors rolling off the line per day, so all the engines plus the major structural components build and assembled in two weeks is not impossible, then it's a matter of apply thermal tiles, install electric and finer plumbing and life support and all that shit, except for the cargo ones and the tankers.

How much money is SpaceX set to make off of Starlink? Globally? I can see all planes and ships get outfitted with a Starlink antenna for in-transit internet, plus the billions of people that have pretty shit internet now. If priced right, they could fund multiple Starships/Super Heavies each month with the internet alone.
Then they can also build a proper space station and lease it to anyone interested for either research or even Hollywood. They could even start this with only Starships orbiting in LEO, send you up on a trip to space with 39 other people for a week for the low price of 50000$ (if the launch costs 2 mil), raise it to 100000$ and it becomes pretty profitable.

Nope, in all three of the orbital ring papers the ring's solid and the ring's covered in a sheet of aluminum wire and a superconducting coating was suggested. Here's the thing though, superconductors do not like AC one bit. You get zero loss, but only if that current never stops. So superconductors are shit for things like motors. And we have to apply force to our ring to counteract drag.
>>tethers
a ring with tethers all the way around the earth is stable, but there's no way in hell we can build it any time soon. 'Near term' only an orbital ring with one or two tethers can be built. There are still some issues with stability that need to be worked out for that one.

I hope they get BTFO and SpaceX builds its own superior tools. Interesting though - sounds like we could very quickly arrive at an 'oh shit' moment where major incumbents start to realise that if their tech is not in space they're potentially fucked, and then we might see an explosion in investment.

Doubt that SpaceX would make tools that are superior to ones made by those other companies (unless Mars specialization turns out to be a bigger issue than previously expected). The heavy industry hasn't had the development restrictions due to government corruption like the aerospace industry has, so their stuff is already pretty good.

Who in the FUCK cares about mass efficient? If it weighs less than 100 tons we can send it with Starship. Also, chances are if it ISN'T mass efficient it's probably much more likely to actually stand up to constant use and abuse on the surface of Mars pushing rocks and dirt around. Remember the 'mass efficient' new wheel design on Curiosity, that started getting torn the fuck up just a year or two into the mission?

More news on the budget: https://spacenews.com/senate-bill-offers-22-75-billion-for-nasa-in-2020/

>Senate bill offers $22.75 billion for NASA in 2020

>Exploration programs received a $1.2 billion increase over 2019 in the bill. That total includes $2.586 billion for the Space Launch System, more than $400 million above 2019 levels, and $1.4 billion for Orion, slightly above 2019 levels. The additional SLS funding includes $300 million for work on the Exploration Upper Stage planned for the Block 1B version of the SLS, funding that the administration did not seek in its original funding request.

>The bill did not fully adopt the $1.6 billion budget amendment submitted by the administration in May. While NASA sought $1 billion for human lunar landers, the bill provides $744 million, which could impact the number and size of awards NASA makes in an ongoing competition.

>“Within the funding provided, NASA will be able to make significant progress in fulfilling the accelerated goal of returning astronauts, including the first woman, to the moon by 2024,” Moran said.

Because it's pointless to waste propellant if you don't have to, even if the cost/kg is substantially improved. You wouldn't need to build a completely new vehicle or anything either, take existing versions and cut out huge chunks of material wherever you can, replace your hydraulics with smaller versions since you'll only need to be putting out 1/3rd the force, strip out the internal combustion engine completely and use a smaller electrical motor instead. As long as it's still structurally sound you can make a lot of cheap and relatively crude modifications to reduce weight without fundamentally building a new piece of equipment or ruining the one you're working with.

The more shit you can bring from earth, the faster you can colonize Mars. It means you can bring more excavtors, more milling machines, more replacement parts, more people, more things you won't be able to make on Mars, but absolutely fucking need. Mass efficient need not mean fragile. Reliability and maintainability are pretty big issues too. Unless you have a huge fucking air lock, and fat chance of that happening with an early colony, it's going to be pretty fucking hard to even fix an excavator built for earth on Mars. Just trying to reuse what we already have is often harder than just doing the engineering from scratch. Reusing stuff we already have is the SLS approach.

You could just take martian dust, melt down some bulk rubber and make asphalt, dig a shallow trench and just pour it in, or just do it the old way and cook up big paving slabs in an oven. Strictly speaking though you just need to clear off stones that could possibly damage your vehicle's treads/tires, vehicles could navigate based on pre-programmed routes or you could just set up waypoints and roughly follow a path laid out by those.

The same way you get rubber for normal asphalt, ground up little pellets of used tire. Put the rubber into a tough drum, use a hammer or piston or something to pack it in as tight as possible for volume efficiency, vacuum most of the air of the container and load a bunch of them into a cargo starship yeah. What's the issue? Colonies are going to need a lot of other bulk resources too to get started, like premade food before they can get their hydroponic setups fully established, same for water, and presumably for nuclear fuel as well since solar is so shit that far from the sun, you'd need several launches worth of solar panels to provide the same amount of energy as a single stirling motor, alternator, and a few kilograms of some spicy rocks.

I'm not the guy advocating for maximum mass cutting, I'm saying take a normal steel bulldozer and just trim as much of the steel as you can without compromising it's structure (in a 1/3rd G environment) and replace the stuff that can't operate in a martian atmosphere. Electric motor, replace liquid lubricant with dry boron lube or something like that, pressurize the cabin or add an oxygen supply for a driver (or replace the cab with an automated system as some farms already do with some of their harvesters and earth movers), but yeah as much as possible I'd say work with existing equipment, modify it as much as you can without compromising it's functions or building new expensive specialist equipment.

Obviously you'd have to get NASA to sign off on your spicy rocks, or lend you some of theirs, or transport their already approved power generating equipment like kilopower reactors. It would be much harder to do but you could also dig up and refine your own spicy rocks, or you could buy spicy rocks from some other country. Another less efficient option than nuclear would be solar-thermal, better than solar because all you need to do is direct heat using mirrors to move your working fluid (or in the case of a stirling motor to create your temperature gradient). You could also add to that by pumping your habitat's waste heat into that system to succ as many watts out of your operation as possible.

At least so far as I know road surface asphalt uses a high proportion of it, it's a composite of a few different components including the asphalt/bitumen itself, ground rubber, recycled oil, and I think the dry component of concrete.

At least with a stirling motor I think you could still get it running with just ambient heat, especially if the cold side is buried or kept in shade. On Mars the cold end could easily be kept well bellow freezing temperatures in that way. Agreed entirely about spicy rock mining too, it could be done but spicy rock cooking is already one of the most technologically intensive and costly tasks here on Earth in a familiar environment, getting any usable nuclear fuel via ISRU is going to take quite a long time unless we really just start launching enormous quantities of resources into space relatively soon.

I guess you could do slow breeding to coax a fully thorium fuel element to generate enough U233 to boot itself up, you'd just have to design a very highly neutron reflective fuel flask, even more so than normally required in fission reactors. I'd probably start with a solid block of thorium infused fluoride salt stored in a non-neutron reflective container, once on site you switch the block to the reactor vessel proper and use a weaker power supply to begin heating it till the solid salt melts, in the highly neutron reflecting environment the thorium will eventually reach a point where it's decay produces enough U233 to initiate a self sustaining fission reaction, at which point you now have a functional molten salt reactor and all of it's innate benefits like self-regulation, high working temperature, low working pressure, and relatively low size and mass per kw of energy generated.

You can just use solar and batteries. Solar is anemic out at Mars' distance from the sun but the low gravity also means you can build things lighter and consequently with less need for lots of horsepower. You'd probably just give it solar fins like the rovers already have and run it off of an electrical motor supplemented by rechargeable batteries or capacitor banks. Instead of spending extra resources and time to have a closed cabin you'd just add some brackets to strap on spare breathing gas cylinders. Anything bigger or more complex and you'd have to establish a small pressurized assembly line. You could either assemble parts shipped from Earth or use additive manufacture to turn bulk metal powders shipped from Earth into components.

Huh, that's a pretty good range for an air powered car, you could just use waste CO2 or compressed nitrogen too it you want a bit more range. Add in the fact that such a vehicle would have a much lower effective weight on Mars and the range becomes very impressive, at 1/3rd of it's effective weight it should have a range of around 375 miles, not to mention that those tanks could visibly be enlarged a good bit without taking up any more necessary space beneath the vehicle. Of course if you wanted to be able to have some pressurized environment inside it would need to be heavier in some parts, it would need insulation, some shielding, breathable gas storage and circulating systems, environment control, proper airtight sealed doors, that could easily cut it's range back a good bit. You could also go in the completely opposite direction though and have your colonists just suit up to drive it and have nothing but some spare air for them and strip it down to nothing more than a frame and wheels with the frame being made of something both very light and cheap like Allite magnesium alloy. That could probably push your range up past 400.

That 375 mile estimate is maybe a bit on the high end, but if you do use allite instead of aluminum you'll cut your frame mass by around 33% while ending up with a more durable frame in the process, assuming the body of the vehicle isn't changed you'd end up with a range of around 270 miles. You could also build an electrical/compressed gas hybrid vehicle with batteries providing power during low-horsepower activity with a small compressed gas motor kicking in for high demand activity.

you want to move as much fucking demandite as possible. You still have rolling resistance and still have to spend energy moving crap uphill(regenerative braking ain't 100% efficient).

Yeah, although with even a single CAT cylinder if the frame is allite, there is no cab (because why have a cab if you're wearing a space suit and not going to pressurize the vehicle?) then I could see something like that having a range more like 50-70 miles. On top of that, I'm not sure about the CAT's engine pressure tolerances but you might be able to make it out of allite as well, further lightening the whole vehicle, especially since you don't have to deal with any substantial heating at all in a compressed gas engine.

I wonder if hydraulics would be lighter, or if the batteries still win out despite being such low power density.

by CAT car, I assume you mean that retarded air car. Being a 'monster truck' or going fast are irrelevant here. If you're doing scouting you're driving off road. If you're driving off road you're going to spend more energy overcoming rolling resistance. This comes from things like deforming the ground and running into rocks. Your vehicle spends energy lifting itself over the rock and you don't necessarily get that energy back even if you've got a monster truck. I will admit compressed air has a high power density, but it has a low energy density, roughly that of lead acid batteries.
>>11000160
efficiency ain't the issue here, it's the energy density. For a scouting vehicle you want to carry lots of energy with you because god knows what trouble you're going to get into. It's probably not a good idea to power a scouting vehicle with something as energy dense as lead acid batteries. Air cars have another problem on Mars too getting clogged with frozen gas. On average Mars is cold, like 210 K. Allowing compressed gas to expand results in it getting colder if we don't supply heat in the expansion process. You could get cold enough to freeze out whatever gas you're using.
>>CO2
is the absolute worst thing you could use. CO2's freezing point is higher than Mars' average temperature. Compressing CO2 will almost certainly result in it becoming dry ice when the tank reaches ambient temp.

>The solution to all these problems is simple, just use trains instead.
Absolutely correct for all solid goods, trains are based as fuck. However, trains are at least mid-game options only, you can't send one from Earth so you need a capable industry on Mars first, able to build all the major components of rail transport. The best early game option for trucking long distances is first of all to avoid needing to go long distances in the first place, by landing right next to as many vital resources as possible, and secondly to just use trucks, which are slower and not efficient but can perform the work necessary. Make your truck mostly batteries by mass and make it weigh a shitload, remember no maximum load restrictions on Mars, basically scale it up until its relatively low payload fraction is still big enough to be worth it.

Insulated pipelines for transporting water would be nice, just insulate it from the ground and from the atmosphere and you could get hundreds of kilometers of flow without any reheating stations required to prevent freezing.

It's not really a skip, it's more like they don't go deep enough to lose enough speed to drop out of orbit entirely, they stay a bit higher and still lose speed but end up in a much lower and slower orbit. The reasoning there is that they can do as many passes as they want into the atmosphere to slow down without eroding the heat shield at all, however if they tried to do direct descent from capture they'd get such a high peak heat that the heat shield would fail.

So I just discovered that nos and vodka make a pretty okay propellant combination if you're not too concerned about Isp (~200s with 24 bar chamber pressure at sea-level with a nozzle optimized for that). Both are "friendly" to the human body and can be taken without too many problems. In fact, both are taken for recreation.

Is this the most 'human friendly while still being useful' propellant?

No, if the heat shields starts to fail the main structure is instantly fucked because steel melts and a temperature about 2000 degrees lower than those ceramic tiles will melt, think of ice being exposed to a 2000 degree blowtorch. If the tiles started to melt, they're already so thin that the metal underneath would start melting almost right away, and soon there'd be effectively plasma cutting torches blasting into the vehicle all over the place until that side of the vehicle failed and the entire thing pancaked, blew up, and was vaporized.

Honestly I'm not interested in better propulsion for getting to Mars. Mars is too close, you can do it with chemical rockets, which means a cheaper option is available than any advanced propulsion system.
Now, that changes if you consider the outer planets, where hohmann transfers are not viable for human transport because they take years and even decades. In that case, chemical doesn't cut it anymore, you NEED better propulsion, and in that case pulsed nuclear makes sense (doesn't have to be Orion scale obviously, but pulsed detonations nonetheless, working with very tiny fuel masses per pulse). Being able to get to Uranus in an Earth year or less with humans in a reusable spacecraft powered via pulsed nuclear pellet propulsion would unlock colonization of pretty much the entire solar system including the Kuiper belt.
