No need. Just tee off the plumbing that's currently handling the RP-1. Then you just activate whichever branch you need at the time, RP-1 or methane.

I bet on my end a dinner & drink(s) out to a bar/restaurant of your choice where we go together and I pay $50 of your tab. You see I want to pay my bet in person and if I loose I get to spend an evening talking with a fellow space enthusiast. Also assuming there are more than 3 takers that the bet is limited to 3 and I get to choose who I take the bets up with. Payment will not be immediate as I will have to schedule a vacation to your area. If I win I will still go to that restaurant with you only you pay up to $50 for my bill.On to the bet. I believe SpaceX will build and fly at least one Raptor powered second stage on a Falcon Heavy before Jan 1, 2020. I expect lots of takers, I know this is definitely a long shot.You should clarify whether any Raptor-powered orbital vehicle mounted on top of the Falcon's first stage counts.Just to make sure that if that hypothetical vehicle is not a classical "second stage" but rather an integrated vehicle, the outcome of the bet is unambiguous.I hadn't thought of that. If you are talking about an integrated second stage and orbital vehicle then yes it would count. I've been told (mostly by Jim) that supplying methane for second stage at 39A is not possible. Trying to get clarification on why has no response, I assume it has to do with TEL possibly no room for extra pipes. I look at the TEL and I think, my god this is huge! and can't imagine insufficient space.

Run separate methane lines. Two separate umbilicals, both feeding off the same LOX line and of RP-1 or methane for the two types of stage. Have two different arms, one of which engages or have an arm for the methane stage with possible adapters for the RP-1 stage.A methane first stage would need a complete different TEL. But swapping the TEL out is not that hard with two cranes.

I look at the TEL and I think, my god this is huge! and can't imagine insufficient space.If a FH launched with a conventional RP-1 second stage but the payload was something methalox powered and Raptor engined, would that count as a win ( built and flew at least one Raptor second stage) or a loss (it technically isn't a second stage, unlike an integrated vehicle) under the revised terms of this bet? If it's a loss, I'd take on one of these 3 bets, as I don't see SpaceX doing a real Raptor S2 for F9 or FH, ever. If it's a win, pass, as I could see them doing this for test purposes.
Just to clarify, a combined second stage and payload which makes it to orbit doesn't count?
I don't know how I can make this clearer.
Quote from: dcporter on 08/21/2017 02:14 amJust to clarify, a combined second stage and payload which makes it to orbit doesn't count?I don't know how I can make this clearer. Bottom three cores (F9 derivatives) are kerosene/lox fueled Merlin engines. Stage above (any possible configuration) methane/lox Raptor engine. Or maybe I should say upper stage NOT Merlin powered?
Kestrel will never fly again ... I'm willing to bet on that one
Quote from: Lar on 08/22/2017 09:17 pmKestrel will never fly again ... I'm willing to bet on that one How does that bet work? If it flies, you buy me beer, and as long as it doesn't, I remind you that never means a very long time?
A thread that has been quiet for too long I will bet that SpaceX launches something towards Mars before January 20th, 2021. Doesn't have to arrive at Mars by that date; has to reach Earth orbit by that date with governmental permission to go to Mars.If I lose, winners must collect their bet in Tampa Fl. Takers?Edit: Excluding the Tesla they already sent.

Takers?Edit: Excluding the Tesla they already sent.I'd take this bet, though it is almost too easy. The Tesla would not count to begin with, since it only has an apogee past Mars orbit, it was never sent towards Mars. The launch window this year is too soon for SpaceX to have a chance of sending Starship this year, and it would make very little sense to send anything between windows, it could actually arrive later than if they just wait for the 2022 window.If this doesn't change your mind, I'll take the easy win. I expect to be in Orlando in the future to either meet friends or watch a launch, so should be able to arrange payment. What value are you willing to bet? (I don't generally like beer, but will take an equivalent drink as an option.)
