Two-Year Delay for SpaceX's Private Spaceport (blastingnews.com) 102

MarkWhittington writes: About a year and a half ago, with then Texas Governor Rick Perry and SpaceX CEO Elon Musk in attendance, ground was broken on the first private spaceport designed to launch rockets vertically near Brownsville, Texas. At the time, SpaceX announced that it expected to launch a rocket a month, either a Falcon 9 or a Falcon Heavy in the skies over South Texas starting in 2016. But then, the Texas spaceport story fell off the face of the Earth, as it were. Fortunately, the Valley Morning Star has an explanation as to why things are taking so long.

      Makes sense.
      I've seen a runway site sitting under huge amounts of dirt to compress it for a year or two.
    • I'm guessing that the delay at the Mars Crossing launch site is because SpaceX has its hands full on rocket upgrades and doing satellite launches to start realizing some money from their backlog, and the new launch site just isn't their highest priority as long as they are having no problems with launching from the Cape and Vandenberg.

      In the long run, having their own site will give them independence from scheduling issues at the Cape and probably allow a faster launch cadence. In the short term, though, th

    For the lazy and if I may pick the low-hanging fruit, here [straits-engineers.com] and here [wikipedia.org] are some articles about soil surcharging. It's actually an interesting technique. They mitigate risk of shear related failure by stiffening the ground.

        Guessing they didn't do the geotechnical survey until the groundbreaking, but value engineering might also be at work. Until they hit a critical mass of launches it might be cheaper to use other facilities. So, decide to surcharge the soil for a couple years rather than piling and using thicker slabs, save lots of money.

        • I'd be surprised if they chose a site without doing the survey. Although the process may be cheaper, multi-year schedule delays carry significant costs & risks. Maybe they just didn't realize how costly this would be and are minimizing the pain overall.

            Or situations changed. Perhaps upfront they were planning to spend more by reinforcing with concrete pylons, and discovered this cheaper situation after the fact. Or perhaps they found they were getting better economics operating out of Florida than they expected and the Texas site became a lower priority. Or a whole host of other things.

            • Is there any indication that the economics our of Florida have improved so much, or even changed? That seems unlikely, particularly with Musk's tendency to be over-optimistic with projections to begin with. If launch economics are better, then that is a reason to accelerate new launch capability, not delay it.

              I think the most likely explanations, and simplest ones, seems to be it was an oversight or that they are so cash starved the needed to slow down the spending.
              • by Rei ( 128717 )

                Actually, things have indeed changed. They're using a different landing platform in the Atlantic, they have been granted limited landing permission, some of the government contracting barriers have been removed, etc. And I'm sure there's a lot of things have changed that aren't readily visible to external observers.

                Why would improved launch economics in Florida justify accelerating the site in Texas?

                • Why would improved launch economics in Florida justify accelerating the site in Texas?

                  The same reason they would build a site in Texas to start with, increasing launch capability to make more money. If launch economics are even better. then you don't slow down your increase in capability. Unless you are thinking there is some reason that launch economics at the new Texas site would be markedly worse, which brings to question the whole plan to begin with. Why not just cancel the thing if that is the case?

                      Please. There is nothing you stated that points to a likely cost difference so significant that the company would shift plans, and none of those items is really new, so you are them implying that they had no clue of those factors when they started the Texas facility.

            That is also the attraction of the Brownsville site: it's like Florida but with better weather. Once the launch operation is up and running at Brownsville, there will be fewer storm delays.

            Along the Texas coast bedrock is 200-300 feet down. Those pillars are to give your foundation some grip and stabilize it. The reason Houston ports can dredge so deep is because they're sitting on sand. Nova chica is no different, ther is no bedrock near the surface. Most of Texas was a inland sea for millions of years, hence the clay and sand all the way up to Dallas.

      • by jeti ( 105266 )
        They aren't. The tax on gas only covers a small part of the cost of road maintenance in the US. Also the wear of roads depends on the axle load with an exponent of four. It's an investment by the state in the hope to collect on other taxes as well.
        • The gas tax is put into a state and federal slush fund. If the gas tax was used only for the highways there would be a huge surplus.

          On avg the state governments put about $0.30/gallon tax and the federal government about $0.50/ gallon

          The US uses over 100 billion gallons of gasoline per year (134 billion in 2013). Thats about 100 billion in gas tax per year.

          Fixing the bridges is about 140 billion according to CNN and that figure is probably exaggerated for effect.

          And of course the $100 billion
          • Given the huge external costs of petroleum extraction and burning, logic would dictate that the gas taxes should be raised, and a *larger* fraction of that revenue should be siphoned off to cover costs other than highways.

            For example, within a few decades the government is going to be footing a multitrillion dollar bill for building seawalls and dikes around much of the United States in a futile attempt to battle rising sea levels. The current gas taxes are a drop in the bucket compared to this looming cost

            • No. If sea levels rise they rise. Good bye to most places below sea level. It would be like the moronic effort to save New Orleans over the last 80 years. It's the Mississippi fu(king Delta. You ain't gonna stop the river for very long with dikes.

              I would be willing to bet you that the rise in sea level is going to be far less that you imagine it to be. If you think it's important than start voting for Libertarian and Free Market candidates who feel that the government should not subsidize flood insurance

            To clarify, the Federal government only taxes 18.4 cents/gallon, which when added to AVERAGE state taxes, puts close to 50 cpg.

            And to jeti's point: The tax difference between diesel and gas is minimal, even though industrial trucking does exponentially more damage to roadways. One solution might be for industrial trucks (semis and 18-wheelers) to fill up at special pumps that record higher taxes per gallon (such as 60 cents per gallon instead of 20.)

    Basically someone forgot that the soil needed to be much more stable than its default state. So they need to put a huge amount of weight on it to get it to settle, and then remove it and build the heavy stuff on top.
    That's it.

    In Maine, a few years ago, a revolutionary new bridge construction technique debuted;

    - Truck in dirt to build the abutment ramps.
    - Let them settle for a year or two. Instead of compacting,
    - Begin building the foundations etc...

    It looks wasteful, but it's efficient from a cost standpoint.
