NASA still had much smaller jumps in capability between flights. Check out the Smarter Every Day NASA talk.

Nobody is going to Mars anytime soon. It's the moon or nothing.

Welcome to Earth. Some countries use different unit systems. (Some even use a hodge podge of multiple systems!) Please enjoy your stay.

By "some countries" you mean United States, Liberia, and Myanmar

You’ll find imperial units in lots of Chinese products too.

After all, they’re the ones manufacturing the imperial screws, etc.

I REALLY wish they would stop displaying ft, mi, lbs. It actually angers me.

Why use English instead of Esperanto?

I don't understand why this is being downvoted. I would love if metric were used universally, but I don't really see any difference between that and wanting a single language to be used universally. In fact, the cost of different languages is certainly much higher than different systems of units. Converting between systems of units is just trivial arithmetic after all.

That was my interpretation of that talk. It seemed like a regurgitation of opinions of an old aerospace engineer. But that's probably unfair to Dustin, I believe that he actually came to that conclusion himself. But it was a really incorrect take that SLS was somehow the "safe bet" in comparison to betting on Starship. The whole talk just seemed insane based on what I knew about both programs.

The payload capacity of Starship version 2 is around 35 tons to LEO. The propellant capacity is 1500 tons. This means it takes 42 tanker loads to fill up one Starship. This means Destin was extremely optimistic with respect to how well Starship is going to perform.

Even with the projected 100 ton payload for V3, the minimum number of flights to refuel a V2 HLS Starship is 15 flights and 26 flights for V3 HLS.

If we are optimistic about New Glenn and the cislunar transporter, then it will take 4 flights to refuel the transporter for each moon landing plus one flight to launch Orion on New Glenn and another three flights to push Orion using the cislunar transporter. There is also a hypothetical option to use a second Blue Moon MK2 between LEO and NRHO plus a crew capsule launch that says in LEO.

Given a budget of 4 billion USD, this could pay for 50 New Glenn flights assuming falcon 9 pricing. 8 flights per moon landing means one moon landing every two months.

That seems pretty promising unlike SpaceX, which is locked entirely behind a functioning reusable second stage or they don't get to participate at all, because expending 15 to 26 upper stages is not viable at all.

But you do you. SLS only has to launch a few times until the cislunar transporter gets established, which means it is exactly the safe bet that the US needs to reach the moon.

I don't think that's the OP's issue, it's just in this context.

Can someone from the industry confirm whether they use metric internally and the stream uses imperial just for the patriotic show or whether imperial units are used because some countries use different unit systems and this is normal?

On a related note, I don't think anyone is bothered buying screens (monitor/phone/...) labeled in inches, but orbital elevations and speeds? Weird.

Good lord, find something else to be angry about. Decades of metric vs imperial threads should have you convinced by now that no matter how hated they are, these units aren't going away any time soon.

Not with this attitude they won't!

In India, decades after metric, many will only understand feet and inches for height, length etc.. Think it's the same in many Asian countries, though some have moved on.

But miles has gone out of fashion. Pounds too..

Yep, 70 tons to LEO is more than the Falcon Heavy.

Thing that doesn’t exist yet will have better specs than thing that’s been in use for over 7 years! News at 10

FYP as it's rather worse than you framed. I'm happy to see more competition in space, because I think it's the single most important domain for humanity. And Blue Origin is making some rapid improvements, but people are dramatically overstating both this and their history/role in space quite significantly.

Blue Origin was founded before SpaceX, back in 2000, and only managed to send a rocket into orbit this year, 25 years later. They remain a complete nonplayer that exists only through the good fortune of endless and clearly unconditional Bezos bucks.

Now if they can keep putting out some good results, ideally start producing some hardware that can compete in terms of price and capability, and generally scaling things up - then I'll be the first to sing their praises. But we're still quite a ways away from that point for now.
