@@filonin2it actually says 105s directly on their website… they’re missing a couple zeroes on it, maybe a typo? Lol “The Direct Fusion Drive is a revolutionary steady state fusion propulsion concept, based on a compact fusion reactor. It will provide power of the order of units of MW, providing both thrust of the order of 10−101N with specific impulses between 103− 105s and auxiliary power to the space system.”

TLDR: Higher Isp = higher exhaust velocity = higher efficiency. Isp is not in seconds because it measures how fast an engine is. It's in seconds because It's inversely proportional to the speed of fuel consumption. A higher Isp means slower fuel consumption, not a slower engine. However, it is directly proportional to exhaust velocity, which in turn gives you the engine's thrust capability.

LLNL's fusion is exactly a microscale H-bomb with lasers for first stage (instead of A-bomb). With proper power source for lasers (read, another reactor) you could build a 1950s-style nuclear pulse engine out of it. That's, probably, all.

I cant express how giddy it makes me that there's any advancements in fusion. I'm not hopeful that it will become viable in my lifetime as an energy source but I hope my generation can lay out the path for the future to use it to it's fullest capacity.

You don't know what you are talking about. It's a shitty engine. You were fooled by the 39 days to Mars headlines. You would need 200 MW of power for that 200 MW generated by an ultra light weight reactor that is science fiction. The fusion reactor they talk about in this video wouldn't be capable of generating that amount of power and if you did get several of those together, it would weigh so much it wouldn't get to Mars in 6 months, much less 39 days.

Even that LLNL "break even" isn't really accurate. It didn't create more energy than the gross of what the entire process took, only what the laser injected. If you factor in the energy required for all the ancillary requirements, like magnetic containment, things like induction and heat losses, it was something like 20-fold short. So, we're still a loooooong way away from viable fusion.

Fission is fine for near future nuclear spacecraft. It will last decades without a refueling and the propellant will run out far sooner anyways. Even with numerous propellant refills the reactor will keep going for a reasonable length of time suitable for space station use, not just a single trip to Mars and back.

The OLM and the booster don't sit on the concrete pad. They sit on the load bearing pilings buried deep in the ground. And all those NEW underground piles for added support were poured over a month ago, so they're already at 85-90% of design strength. Relax. ;-)

Raising velocity in order to reduce the time required to reach e.g. Mars sounds wonderful! However, once you reach your destination, you will also need to reduce your velocity in order to land. Does this mean nothing more than that it will actually take twice as long to reach your destination?

Russia has been working on the project of a nuclear tug "Zeus" for many years - a spacecraft with a nuclear reactor. Its first version is to fly on ion thrusters, very large ones. They are ready and tested. And the next version of the tug can be equipped with rotary magneto-plasma engines. In general, it is very similar to what you are talking about in this video. Russia has been working on this technology for several years. The first flight of the tug is scheduled for 2030. First he will go to Venus, drop one probe there. Then a gravitational maneuver and flight to Jupiter, more precisely, to its moons. In the future, I would like to see a collaboration between Russia and the United States (because when will all this enmity end?). Future, more powerful versions of the nuclear tug could work in conjunction with Starship. Starship can put a large payload into orbit. And Zeus can deliver it to the Moon or Mars. Not very fast, but very very cheap.

If we can’t get a fusion or nuclear engine working we will likely never leave the solar system for the next 300-500 years.

Sorry, but an Isp of 105 seconds must be an error for the proposed engine.The pulsarfusion site quotes an exhaust velocity of 110 to 350 km/s which corresponds to an Isp of about 11 000 to 35 000 seconds.

On fusion drive - a little confusion over fusion reactors for power generation AND for a fusion drive.

How much does the Booster weigh, and does it weigh more when it is pressurized to stop the domes crumpling?

nuclear fusion rocket is like putting the cart before the horse. Get a fusion powerplant online first, then you can begin research fusion rockets. Everything is pointless until then.

Going from earth to mars in 12 days may cause a few time dilation issues. Now with a Alcubierre drive we won't need to worry about that. If course the most energy efficient version that I know of uses 3 solar masses. However this is tiny compared to the original dozen observable universes.
