Remember a user named TripleSeven?
Do you think that...?  No! It couldn't possibly be!

It's not funny, I remember the user TripleSeven a Boeing pilot who if I remember correctly, lived in Turkey, I have nothing to do with it, my English is not perfect, I used to live in Spain, and now on the Space Coast. My name is Erick.

Blue origin begun testing rocket powered VTOL in 2005 and had patented ocean recovery in 2010. https://patents.google.com/patent/US8678321

So far BO is the one that had been leapfrogged.

For anyone who counts economics as basic to any activity, you will know that Blue's budget until 2015 was small, and it only had 500 employees by that date.

Since 2015 is when the company was really relaunched in terms of staff and budget...

Then I think the effect of staff and budget is pretty well spoken, BO had debuted one operating vehicle and several experimental vehicles by 2015, and zero since then.

SLS had seen two core stages and five SRB thoroughly tested before Artemis 1, when New Glenn and Jarvis have that much hardware and test, I will start to take your assumption seriously.

2024 will show us...

Yes, then you can wait for 2024(or late 2023 if we are lucky), when New Glenn first stage completes WDR before opening this “threat”

Unlike you, I don't believe in impossibilities, and I do believe in probabilities, and many assume guaranteed that Starship cannot be surpassed in its development of 100% reusable, however I am skeptical and say that although I don't know the exact number, certainly Blue has more than a 0% chance of making it...

Similarly, wait for the probability become bigger before opening the thread. The only thing you can prove is it is greater than zero, but not many will be interested if the probability is effectively infinitely close to zero.


I thought this was an astronautics discussion forum and by the way next time I'm going to open a thread I'll ask you first?

By the way these are great things or not?

By the way, NASA almost invented the term KISS, which enhances the figure of uncomplicated and the efficiency of simple.

Many skeptics think that the BE-4 is a simpler and safer engine than the Raptor, and that in the long run it will be better for being very reusable. Time will tell if KISS holds true in this case...

Not better just different. All engine types have their pros and cons.

I am just giving you suggestion lest us waste two more pages on unconstructive discussion.

Many skeptics think that the BE-4 is a simpler and safer engine than the Raptor, and that in the long run it will be better for being very reusable. Time will tell if KISS holds true in this case...

Can you give us source on who the "Many skeptics" are and what did they say? And
how exactly is an engine with more turbo pumps and turbine (BE-4 has boost pump while Raptor doesn't) simpler? After all, why use the historically notorious ORSC rather than Gas Generator Cycle if you want to pursue simplicity, like Aeon R?

Applying your logic, I think there is greater possibility that Relativity can leapfrog Blue to full reusability, why don't us discuss this?
