Monthly Questions and Discussion Thread
Welcome to the monthly questions and discussion thread! Drop in to ask and answer any questions related to SpaceX or spaceflight in general, or just for a chat to discuss SpaceX's exciting progress. If you have a question that is likely to generate open discussion or speculation, you can also submit it to the subreddit as a text post.
If your question is about space, astrophysics or astronomy then the r/Space questions thread may be a better fit.
If your question is about the Starlink satellite constellation then check the r/Starlink Questions Thread and FAQ page.

Meta This sub is not about Musk. it does not endorse him, nor does it attack him. We generally ignore him other than when it comes to direct SpaceX news.
Be advised this sub utilizes "crowd control" for both comments and for posts. If you have little or negative karma here your post/comment may not appear unless manually approved which may take a little time.
If you are here just to make political comments and not discuss SpaceX, you will be banned without warning and ignored when you complain, so don't even bother trying, no one will see it anyways.
Friendly reminder: People CAN support SpaceX without supporting Musk. Just like people can still use X without caring about him. Following SpaceX doesn't make anyone a bad person and if you disagree, you're not welcome here.

Discussion If Flight 14 is indeed orbital, where will it splash down?
My take is:
Indian Ocean off of Australia like always
In one if the new zones approved as ‘contingencies’ like Hawaii, Aleutian Islands, or off of Peru
Off the coast of Starbase, Texas

Discussion Will flight 14 attempt to avoid or perhaps better exploit a situation where starship survives splashdown?
If they wanted to avoid it it probably wouldn't be too hard, just have it target a point higher up to get a higher fall, however considering that they did seem to find the data from flight 13 valuable is it possible they have tried to prepare logistically to be able to recover flight 14s starship faster?

Where is SpaceX going to park dozens Starships and Super Heavies once launch cadence ramps up?
With Starfactory and the giant new Gigabay expanding Starbase's production footprint, a logistical question keeps popping into my head: where are they going to actually store all the fleet hardware once we reach regular launch cadences?
Gigabay work cells are designed for active assembly, integration, and heavy maintenance, not sitting on ships for weeks. If SpaceX achieves rapid turnaround with dozens of boosters and upper stages cycling through, the staging yard requirements will be massive.
So, will we see dedicated outdoor "parking lots" or massive low-cost storage hangars pop up near launch sites?
More importantly, will they use vertical or horizontal storage?
Vertical Storage: Super Heavy is designed to stand vertically. Keeping boosters vertical avoids complex rotation dynamics, preserves structural integrity without needing horizontal support rigs, and keeps them aligned for tower integration. But tall vertical hangars are insanely expensive and susceptible to high winds.
Horizontal Storage: Laying them down makes horizontal storage sheds cheap and easy to build, but can stainless steel thin-wall tanks handle horizontal shear loads without constant interior pressurization?
How do you think SpaceX handles vehicle buffer storage as turnaround times shrink? Simple outdoor stands, or massive horizontal storage yards?

Fan Art I built a small metal model of a falcon 9 rocket. It posed with Dishy and my router+mini.
I thought it was cool that I bought a Falcon 9 using Starlink and it got to pose with Dishy and the routers. It is a bit taller than the router mini. I started it a few months ago and built the engines quickly, paused for a few days and built the rocket, paused for a few weeks and built the crew dragon capsule and finally finished the base, strongback, and connected everything a few minutes ago.
This post was also made from Starlink so quite a lot of Spacex was used to get and post this. It’s also insane as I used to live in Florida for a few years and there is a good chance I could have watched a launch that launched a satellite that I am connected to now or have connected to recently.

Starship Starbase LA’s many pads may be for simultaneous terminator-plane launches
I was surprised SpaceX is proposing 10+ pads but only ~2 launches/day/pad, given their goal of extremely rapid Starship turnaround. Why build so many pads if each can be reused quickly?
One explanation: most launches may be targeting the same dawn/dusk SSO plane for orbital compute and near-continuous sunlight. From Louisiana, there may only be one useful southbound window into that plane each day.
So the pads may be about parallel launch capacity, not turnaround: launching a large number of Starships in rapid succession during the same daily window.
Curious what people think.

Raptor Engine Fluid Model
Hi everyone! A few weeks ago, I released my open-source lumped-parameter dynamic fluid system solver, FullFlow, and mentioned that it could be used to model steady-state and transient flow in real rocket engines. So, I decided to showcase those abilities with my favorite rocket engine, SpaceX's Raptor Engine.
Raptor is a full-flow staged combustion engine, so it's particularly hard to model correctly, especially with the multiple combustion preburners, regen channels, turbopumps, etc. With the public data I had available, I was able to construct and validate (to the best of my ability) a steady-state model of Raptor 2. I used FullFlow to model the fluid pathways and components and ThermoProp to model the fluid/material properties and combustion.
Of course, there are some deviations from reality, especially since there is only so much public data available. I had to estimate many data points like turbomachinery curves or valve geometries. I also didn't have the proper tools to model supercritical combustion flow for the preburners or hot-gas manifolds. Also, I didn't have access to empirical efficiency values for components like the nozzle or pumps.
Eventually, given enough data, I hope to make a transient simulation of Raptor using FullFlow. I also hope that I can eventually apply these tools and skills to the actual Raptor engine or other industry engines!

What are the major advantages of the Raptor over the Merlin 1D?
I had assumed the foremost advantage of the Raptor was simply being much more powerful. However, then I realized that the thrust-to-weight ratio of the Raptor 3, while impressive, is actually still roughly on par with the max TWR of the Merlin 1D in the range of 180:1. So I want to ask, what are the general things that should make the Raptor much better? Is it mainly just for the benefits of using cleaner methalox fuel? Are there any other distinct advantages?

Abort options for Starship when attempting catch
What options are available for the Ship once it starts to make its way to the tower for a catch attempt, but they realise it isn't going to make it? Would they terminate it mid air (FTS)? Can only assume this scenario would happen at least once at some point

Forte has finally fully poked above the water. S40 is safe on deck. Hopefully we’ll see her back at Starbase in a few weeks time!
