Title: Predict accuracy of upcoming DSCOVR Mission attempted barge landing
Post by: robertross on 01/13/2015 06:55 PM
I figured I'd start the second poll.

I hope my suggestions meet with everyone's approval.

I'm picking option 3

On the barge intact, probably offcenter (but hoping for a bulls-eye!)

Picked three FIVE, nearly exactly the same response as I posted CRS-5 (pesky hydraulic fluid  ::) ). Hopefully this time I'm on the money.

Edit: I realised I'd had three written up there for Dieu knows how long... Doh!

I think they have all the data they need to land on TOP of the barge next time. The question is how close they can get to ideal touchdown velocity and what their safety margins are on the legs. I wouldn't be shocked if they damage a leg or two on an otherwise on-target landing. Hopefully not enough damage that the vehicle collapses or tips over.

I'm fairly confident they'll get it right this time.  I voted three, but I think it will be close enough.  When they start sticking it in the bullseye every time, the FAA will have no excuse not to let them fly back to land.

*edit:  Actually I voted 4, with the majority.  I don't count well.

I'm going for center, for the same reason as last time - unless there's a malfunction, we already know how well GH landed.

Post by: Mongo62 on 01/13/2015 09:53 PM
I voted for center. We know that the stage can get to the ASDS even with the grid-fin hydraulic failure, so absent another mechanical failure, I see no reason why the stage should not stick a dead-center landing.

Except they have to fly 200 more miles back to CCAFS.  Seems reasonable to me that they move the ASDS closer to CCAFS with each launch as there data gets better.  But can always go back to being further off shore for more fuel intense launches or FH center cores.

Edit: I don't think they'll nail it in the center, but I think at least foot pad is inside the circle.

I think they'll stick the landing - it won't be perfectly in the center but it won't be far off.  Call me an optimist, but Elon said in his interview today they would have landed CRS-5 but for the hydraulic fluid exhaustion - and that was in pitch darkness and fog.
Would like to see another poll question:  When will we see the first footage of a F9 first stage landing on the ASDS?

According to Hans at the CRS-5 pre-launch presser, if the landing was successful video would be released in a day ... or two.  I imagine the same will hold true for DSCOVR.

I'm suspecting that this is the answer. SpaceX got nailed in the press for what many outlets called a failure even though the orbital insertion was successful, the docking was successful, and the end result of the landing attempt was the exact same thing that happens to every other first stage. If I were them I wouldn't release footage of the first ASDS attempt either, no matter how much we would all love to know what happened, because of how moronic the average press coverage is. I suspect that the same press will happily laud them for a successful landing though, and then we'll see as many angles as we want.

I do hope that after a bunch of successes they might get brave and show the footage from the CRS-5 landing attempt, by then there won't be much for the press to say.

I'll take that bet.  I think we'll see footage of the CRS-5 attempt, and it will be released before DSCOVR launches.

I'm not guaranteeing that the CRS-5 footage will include the earth-shattering kaboom.  But I bet descent footage will be released and -- to make the wager interesting -- I'll say that we see at least a glimpse of the ASDS before the clip ends.  (This last part is really iffy, considering darkness and fog and possible loss-of-control, but @coypu76 did say "landing on the ASDS", so I can't claim I'm right unless we actually see some ASDS.)

From my post on the Open hydraulic schemes thread:

Elon elaborated on the grid fin issue at a recent Tesla International Auto Show (https://www.youtube.com/watch?v=wB_WqlOIlXc#t=539) Q & A, where he states that SpaceX needs "to make sure our hydraulic actuators don't run out of fluid and go hard over".

I'm taking option 3 since that would be awesome enough. A bull eye landing would be just extra gravy, leave that buzz for the follow on barge landings. BTW, I'm betting the FAA will demand another 3 landings (DSCOVR + two).

I voted for the third option - partially or wholly on the barge, but with some damage. I expect the unexpected for the first several attempts - one leg over the edge, causing a topple, or offset onto the equipment containers ... something.

But I'd like to be proven incorrect.
Title: Re: Predict accuracy of upcoming DSCOVR Mission attempted barge landing
Post by: PahTo on 01/14/2015 07:15 PM

Option 3 due to the fact they flew back to the platform last time, and have (apparently) ID'd why they didn't land intact and are making changes.

Title: Re: Predict accuracy of upcoming DSCOVR Mission attempted barge landing
Post by: Llian Rhydderch on 01/15/2015 04:24 AM
I'll say inside the circle.

They've already successfully demonstrated all the high-altitude controlled-descent stuff, and the mid-altitude controllability to GNC to the "barge box".  Grasshopper/F9R-Dev1 have demonstrated the low-altitude precision landing capability.

I'm speculating that ocean swell, barge thruster vernier control and potential fog and rain, won't overcome the SpaceX control algorithms and control authority to remain in the circle.

I went with 3, which is a down grade from the last poll.

If you play by the rules of Baysian statistics then the odds worsen for a failed attempt.  :(

Normal statistics would say it's still 50/50.

Personally I'd like to think they have learned sufficient about oil usage and other issues to bring it down safely.

But I thought that on their first attempt as well.  :(

So the question is have they found all the "unknown unknowns"  this time ?

The trouble with that approach is the occurrence of a failed attempt only gives evidence about the true state of the world at the moment of that failure, and doesn't account for things like, say, adding 50% more hydraulic fluid on the next attempt. In the real world, with clever engineers, the odds improve after a failed attempt. See FTG-06b, for another example.

However, let me note that if that Falcon 9 ACS - not taking in account all due differences, of course - was mounted on an ICBM in the future it would be an improvement (http://en.wikipedia.org/wiki/Multiple_independently_targetable_reentry_vehicle)!

Ahh... no: Bayes reasoning does not say that. If you are looking at THE SAME probability distribution and you get more information - like a data point on it for failure. then yes, your estimates going forward of what that distribution looks like will change, maybe with a greater failure possibility, maybe not, depending on the prior model. In this case you are looking at a new probability distribution which we know is different -  more fluid, different trajectory, higher starting point, etc., so your estimate will have to add all that in to get your new estimated outcome model. That will be your new "prior". It may very well have a lower possibility of success, but it won't just be because of the previous failure, since a lot more stuff is changing, and you know it is, in the sense that you should be incorporating it into your prior probability model for the new launch.

Pedantic mode off. I do this because I see it this for all kinds of predictive statistics and these  ideas can really lead to funny decision making.

I voted #1... because this stage is going into new territory... higher and faster at time of turn around... it just seems to me that the unknowable unknowns increase dramatically, and after the CRS-5 landing attempt, I'm not so positive as I was... I was stuck between #1 and #2, and went the way I did based on Elon's comment that this is trickier... I don't think they will have the same problems as last time, but I am suspicious they will find new reasons for the stage to do a RUD... not that I want it, I would prefer a repeat or better of CRS-5... maybe I would change my mind if it were after 8 pm and the bottle was open :D

I picked 5. You have to be optimistic. If a malfunction happens, it's bad luck. If it works, I think it's going to be pretty much on target based on how close the last one was after the grid fins ran out of hydraulic fluid. So, I just picked an option under the assumption "it works." And, based on the accuracy of their previous predictions and tendency to under-promise and over-deliver, I think it'll work.

But I'm going to bet that it will be delayed by at least a few days and we won't see it until February.
Title: Re: Predict accuracy of upcoming DSCOVR Mission attempted barge landing
Post by: intrepidpursuit on 01/18/2015 08:09 AM
I picked 5 because I'm optimistic. Even with the grid fins working against them they looked to be close to dead on with their 45 degree rocket.

A close second to me is 1, because I think there is a high likelihood that they have miscalculated or measured something related to their incredible T>W, 0 speed, 0 altitude final maneuver which has still never really been tried.

The others are distant runners up. SpaceX doesn't seem to do anything halfway. It will either get there or something will go wrong.

Also must consider potential failure modes... not the least of which during last attempt was returning to the vicinity of the ASDS in a rather large ocean.  Sticking the landing was relatively minor in comparison. 

Combining success on the former with changes to improve odds of the latter should significantly improve the odds on this attempt.

I think its the other way round. Getting close to he barge is the 'easy' bit, landing it is the tough bit. They have grid fins and a lot (comparitivly) time to aim and redirect the stage to get it close to the barge. The landing itself is a one off lots of things need to go right at the same time brown trouser moment.

April. CRS-6.

Two GTO missions before that without legs.

No idea when uprated Merlin-1D will fly - not before April at least.
