Think Saturn 5 was 1.1 TWR, this was on purpose as longer fuselages and more fuel is cheaper than more engines. Later on SRB become standard to kick the rocket up. For reusability higher TWR has benefits, way more so if you want to do an boost back. Now engines might be run below max trust to increase reliability?

I agree except they should be to high to be close to even 0.1 bar at this point. But warming your feet with an bonefire while wearing heavy boots is not that smart. Heard of people melting ski boots so the can not put on the skis afterward.

I say leaving out 200 m/s for safety on an test launch count as orbital. Its obvious an fail if you try to launch something to orbit unless you had an kick stage who is an 3 or 4th stage anyway. But this leaves SS as the winner. Race is who put an usable payload into orbit.

Here I agree, now an horse don't know traffic rules but its rules who can be added and with the expectation that others might break the rules. In Norway we have an term plank driving, as in child's play, its dates to the people using horse and cart taking planks from the sawmill to the train station the horse did the driving having done it for years. Horse like most mammals are pretty smart.

Think the idea was that you could put lots of stuff in the center like an caro or passenger pod, perhaps an turret. The recolless rifle show is stupid as the backblast would easy hit the pilot. Putting an flamethrower on it is as shown also stupid as its an short range weapon, the downdraft don't help.

I see two errors here.

Not all high explosives are very stable like nitroglycerin. I assume that gunpowder and solid rocket fuel is more energetic, but they don't detonate and are easier to set off. The wet dream battery uses air as in oxygen as one part. You don't need to carry the air unless underwater or in space and shutting off air intake and its pretty inert. Only downside in a plane as it get heaver as drained.

Yes, but then you have an set top box with the same problems, workmate had internet go down so he watched TV, cable was still up but he could not change canal without internet because the software require it to switch.

Its pretty common for stuff need to be unplugged to reboot it. Especially stuff who is on hot stand by like an TV. And its an computer in it even if not Smart. Unlike many smart items an smart TV makes sense as you can use it to stream without an separate box for this.

Yes with more energy density you will get an more energetic fire. Think gunpowder burning, like gunpowder you also don't need oxygen for the fire and if you try to contain it, it explodes. I assume batteries like this would be restricted the way gunpowder and other explosives is. Now its probably ways to make these batteries safer even if it cost some performance.

Scrubbed

Morning here in Europe, and delayed again past 8:00 GMT. In last hour of their window now so an chance for scrub.

I say it was pretty obvious New Glen would compete with Vulcan Centaur as its an good overlap in estimated capabilities. Still its no law saying you can not do this. ULA can complain that the engines was delayed who was an serious problem for them.

Thank for it. Now I assume an version with an faring not an cargo hold would be single use. Yes you could probably made it reusable but don't think they bother unless its an marked for it like some want an group of really huge satellites into orbit. Wondered about this but, the initial idea was to make it of carbon fiber who would be don horizontally. With steel its easier to build vertically.

Excellent point, now this does not matter in a gun, but modern gunpowder is more powerful so using same amount of it in an gun designed for black powder would be an bad idea.

Using model rockets as baseline Now modern gunpowder is more energetic but its not designed as rocket fuel. 240 s for the SRB is very good. Now that is the ISP of common small to mid sized missiles? I guess around 200 s.

The design is typically tested with dedicated test version. Not the stages who is launched. Test versions of stages are common and is also used to test handling, fueling and similar.

Now this sounds like some cool stuff You know the idea of flying an plane using large wire based ion engines, stupid idea but looks like it works pretty well for small airflow in laptops and similar and its silent. Downside is that it needs 5000 volt so an power ramp up system who takes up more space than the fans so you will not use just one tiny one unless they can scale that down but unlikely an device with one small makes sense. Not sure how well it scales up probably well up to an scale and 120 mm fans moving slowly don't make much sound anyway.

Should it not be have burn marks, I assume it came down with other stuff who burned away. Starting to think hoax, some weird machine part some jokers dumped in the forest for an laugh. A bit depend on distance from roads and tracks. Its not something you carry trough thick underbrush for many km.

Steam rockets should get an significantly higher ISP or more likely trust as i assume it used super heated water who turn into steam then "fired". Still pretty crappy, fine for launching planes of an carrier as the catapult is stage zero and part of the ship.

Agree, I think its machined but probably not massive but has voids on the top who I assume would be the bottom.

Had an cat eating part of an fish under my chair while I was eating the rest at an outdoor restaurant in Egypt My guess is that camels come to late to be included among the gods.

If they aim for an moon flyby they can either send it into deep space with an moon slingshot: classic KSP moon satellite mission where you forget to add solar panels. Or an free return trajectory where it impact some planned place on earth, might even an moon impact. All is nice to show you can control second stage for days I assume.

Ruined your night vision that, would be an big one. Saw one as an teen who was impressive more so it flashed then went dark and started up again. One in gang said it was an anti air missile test as it looked as it was going up and it was an two stage missile. Who we agree on, plausible outside you don't test long range SAM in populated areas.

Very good point, I say the same is true for the moon. For an sizable base an nuclear reactor is an good option not for landers. It would also boost robotic missions who is even more relevant with an manned base as you don't want the rovers moving some hundred meters a day but some hundred km who is reasonable for an off road in an desert.
