Any idea what the highest amount of re-uses for an F9 is?

 

I think a couple have reached 7.


Edit- well, one has

I thought it was 6 or so. I wonder if there is a threshold where they don't reuse them?

 

With Spacex’s model of reusability, I wonder if the have it figured out to an “overhaul” schedule. Sort of like aircraft engines and airframes.
I’m sure even if decommissioned, that segments will be re-used in some form.

 

The goal is 10 but then again, I’m sure if they determine more could be had, they’d go for it.

 

They would have to be. Right down to x-raying every square inch of metal.

It would be neat to see some of the first F9's still flying 30-40 years from now.

 

How long is the travel from Earth to Mars going to take for those lucky enough to go?

 

Just bought a patch today, not sure if others are interested but it is based off a great poem.

3-4 months for a higher energy trip (which is what SpaceX is planning). https://en.wikipedia.org/wiki/SpaceX_Mars_program

https://www.theverge.com/2016/9/28/...mars-plan-habitat-radiation-funding-questions discusses some of the transit time questions too.

 

Sounds like no one here actually works at Blue.

 

I'd like to see the Blue opinion. (assuming this was allowed by their employer)

I mean face it - BE-4 isn't flying. New Shepard is a suborbital test vehicle. BE-7 also hasn't flew.

Public facing launches, or failing that, timeline to such things. If your test stand video isn't full duration and doesn't say what it's trying to simulate.. not sure I really care either.

 

I am curious to inquire what you are doing to progress space exploration

 

Probably as much as anyone else in this thread - paying taxes to subsidize it.

 

Blue origin is privately funded

 

Ish. The New Glenn, lunar landing system and BE-4 are all benefiting from tax payer funding

 

Do tell kind sir

The BE-4 engine is also being used on ULAs Vulcan which is also taxpayer subsidized.

 

Paying attention?

I'm sure that BE4, BE3U, and BE7 are on track and going to meet their timelines. But then again, I'd also be mildly (and pleasantly) surprised if they do, as they don't exactly put a ton of information out there about their goals and progress, now do they.

NG has won an interim contract and certification, but still - platform on pad is zero. BO's HLS is in early designs and looks to be the worst of the systems proposed mass/efficiency/costwise, imo, and BE4 is gonna feature on vulcan first.. maybe this year if the schedule doesn't slip wayyy to the right.

I mean I'd be glad to be proven wrong. I'm just an observer, and you know - things like rockets leaving the ground and going into orbit > rooting for any particular team.

 

The RS25 is a proven engine, after all. How far down the road of the hot fire green run are we again on that one? How many starship prototypes have actually flown in the time the time it took to complete that test series? Obviously it's not Blue Origin, but stuff leaving the pad in the public eye > test stand run.
