Will we have to wait for Block V for a second reuse?

5 is way too few for an upper bound, also you omitted 0 as a choice.  Also your end date isn't standard, way too short. Also you didn't crosslink other polls. Also the name doesn't match convention.

Changed end date to be about 30 days out, added some choices, renamed poll to match convention (all polls go in the Polls section and start with "POLL:", added crosslink to landed stages poll.

Interesting poll. My vote is 7 since I voted 25 successful landings and 30 flights.

Maybe I misunderstood, but I thought this poll was asking if in 2018 we'd see the 3rd/4th/5th flight of the SAME Booster.

no, parse it again...
"reuse a stage for a second time"  == 3 flights on one booster, initial and two reuses
"number of times SpaceX will" == how many boosters will get to do this.

So far NO booster has flown a third time. Some statements have indicated that for block 3 and 4, 3 is the max.

I voted 2. Various factors:

- I don’t think it will happen until block 5
- First block 5 flight in Feb/March
- I think at least 40% of flights will be new boosters
- Guessing it’ll be Q3 before gap between uses of same booster is less than 2 months

So I’m guessing a small number of boosters that’ll have time to get 3 flights into 2018

My opinion is that only boosters that have flown two LEO missions are eligible for a second reflight.

With that being said, I'm gonna guess that seven of these instances will occur next year.

2018 is the year of Block 5 which I suspect should be reusable on virtually any recoverable mission.

4

One booster will fly 4 times (likely first Block 5), so that's 2 flights more than second time.
Two additional boosters will fly a third time, one block 5 and one previous block (either Iridium Next or CRS-xx).

I picked 3 and I think that is slightly aggressive.

They have to introduce the Block 5, recover, study, reuse then reuse a booster for the 3rd time for the first time.

If they manage to reach 3 it might be late in 2018.  But they that’s only a year away and we have plenty to entertain ourselves with, FH, Dragon 2, block 5, high flight rate, star link and flying electric cars.

Edit: luckily the existing stock of used Block 3’s give them a head start and on number of launches.

Wildly optimistic prediction, Superheavy recovery on IFT-4 or IFT-5

After Iridium 4, we can be pretty confident that the remaining block IIIs will only fly twice.

Do we know whether block IVs will fly three times? If they will and SpaceX doesn't have to wait for block V, then I think we would see more third flights in 2018.

My vote is four. It may a little high, but I underestimated SpaceX in 2017.

The title was confusing! You said” reuse a second time” and I thought it was USE a second time so I guessed 12. Likely way too high. My own fault for not carefully reading the question before voting.

The only stage type that will re-fly 2+ times is the Block V
.
The *first* block V has not flown yet, but is due rather soon.

I believe by end of 2018 we will have a nice stable of returned Block V first stages,
a (small) handful of stages that have flown a second time,
but none that will get launched a third time.
.
The limitation here is not the ability to re-fly, but the timezone since the first flight,
and the introduction of Block V preventing "older" models from being tested to third flight.

The SpaceX webcast for Merah Putih today said that the plan is to fly the 1046 booster for a third time (ie second reuse) later this year.

So we now know for sure this is the imminent Spaceflight SSO-A launch:

Looks like that will be the only flight this year where the booster has its third flight (unless NASA has progressed to allowing a block 5 to be reused more than once for CRS-16).

In 2018, how many Space- Ex first stages will be used for a 3rd mission?

A more interesting POLL.
How many times can refried beans, be fried, before becoming over-fried? j/k

In biology the terms gravidity refers to the number of times a female has been pregnant, and parity refers to the number of times a successful birth has occurred.

I suppose in the era of reusable vehicles, the parity of said vehicles will be of some relevance.  Some of the shuttle SRB components must have a quite high parity number, unfortunately in that example there would also be a number for abortus, or pregnancies that were not successful.

I guess someone had better start the gravidity, parity and abortus charts for the sPace ex vehicles.

The count is now at 1. The question now is will there be a second one in 2018. There is only 2 F9 flights remaining for 2018 without a specification of a booster.

The final Iridium bus flight is using B1049. IIRC the GPS III-1 flight is using B1054. So that only leave the CRS-16 Dragon flight without a specified booster core.

Not quite at one yet, there could be an abort or mishap that prevents launch until next year, or even a mishap that destroys the booster well prior to launch. Let's not count our chickens pre-hatch.
