      Unfortunately, the next competitor will be Amazon…

      And then we’ll see what happens next, getting a whole constellation up is no small feat, I can’t see a third company getting a system working before 2050.

        The satellite constellation is the natural consequence of cheaper rockets. It’s a true paradigm shift, but the pioneer in this case has only the moat of being able to spend less money per launch. If someone else can deliver payloads to low earth orbit for less than $2,000/kg, then they’ll easily be able to launch a Starlink competitor.

          Again, the only possible player that could do that any time soon is blue origin/Amazon.

          Stoke Space is working on a fully reusable rocket though, I’m really impressed with their rocket concept, some very smart design choices were made. They do have working hardware and have demonstrated their core engine. But I have no idea how close they are to first launch tests, I expect it will be a while

            Arianespace has fallen behind, but they’re not out of the picture. They’re still by far the largest competitor to SpaceX, and they’re aiming for their 7th generation Ariane to be a reusable design.

            Arianespace is an Airbus and Safran subsidiary, so it’s not like they don’t have the engineering oomph behind them.

            Your original comment said 2050, which is a long way off. SpaceX’s first launch attempt was in 2006, their first successful launch was in 2008, their first successful recovery of a rocket in reusable condition was in 2015, and first reused a rocket in 2017. If they can make progress on that kind of timeline, why wouldn’t someone else be able to?

              That’s a fair point. Keep in mind though, it takes a while to get a whole constellation up in orbit and get all the kinks worked out, Starlink was first usable in 2020. So in total it took them in the area of 14 years from start to finish. It’s also worth noting, that nobody in the space industry has really ever been able to move as fast as spaceX, they’re something of an anomaly, not the norm.

              So could a new company do it in 14 years? Yeah, that’s definitely possible. It could happen by 2039, but I wouldn’t put money on it. 25 years seems more likely.

        Also with starlink even one company’s constellation is causing issues with astronomers and launches.

        How bad will it be if there are 5-6 different companies with their own network floating around up there. And then other countries with their own network.

          Yeah, it’s a bad situation. I’m against monopolies, but I also see how filling the sky with redundant satellites is a terrible plan, so I don’t like the idea of lots of competition either.

          I think low orbit satellite communications is a pretty awesome concept. It has the potential to become like a second Internet backbone, but a backbone that can bring data directly to users without the additional router hops that local ISPs introduce. On paper, it’s amazingly efficient and can distribute service to all of the world… But in practice the business and management side is deeply problematic. One company should absolutely not be in charge of global Internet service. And one country would not be any better.

          The only solution I can see is to make it safe and feasible to have way more satellites operating in low earth orbit. I’m really not sure what that solution might look like…

          Here’s an off-the-cuff idea though: One solution could be an extremely robust low earth orbit maintenance and “pruning” system. All satellites would need to be monitored by third parties. And those third parties would need the authority and ability to quickly deorbit (prune) any satellite that deviates from its exact expected orbit. If satellites can ensure no deviation from their path and can safely maneuver to avoid collisions, it could be possible for many more satellites to safely share an orbital altitude.

            Deorbiting is all well and good, but more and more we’re finding that these satellites contain chemicals that are very disruptive to the ozone layer. It’s going to be CFCs all over again, but with even more corporate capture of government.

              That’s a fair point. The alternative is taking things up to a “graveyard orbit” somewhere between LEO and GSO, to a particularly unpopular altitude, where nobody’s fighting for real estate. Satellites can sit there indefinitely, you could even clump them up in a big ball, the tiny pull of gravity they have is actually enough to keep them bunched together.

              The only problem with that plan is that it takes a lot of energy to raise an orbit that much, I’m not sure how to make that feasible.

                Lowering the orbit takes energy, too, unless you’re relying solely on atmospheric drag.

        I know Blue Horizon or whatever it’s called has had minor success with rockets. What’s stopping Honda from out-competing them? Could it be a funding problem? (I know Blue Horizon has a lot of Amazon funding)

          Well yeah, blue origin has already successfully orbited their rocket. Their rocket which has a 45 ton to low earth orbit payload capacity, about the same as the Saturn V (so actually impressive as fuck).

          So the head start is what keeps Honda from out competing them. They’re at least 10 years ahead of Honda (but likely more). And BO is solely focused on space, Honda on the other hand isn’t going to prioritize that arm of development over others. So I can’t really see Honda winning that sprint, if they’re not totally committed to the race.

    This wasn’t much more than a toy rocket:

    6.3 m in length, 85 cm in diameter,
    The test was completed successfully, the first time Honda landed a rocket after reaching an altitude of nearly 300 meters.

    But still they were successful on their first try, so we will have to see where they take it from here. 🚀

        Whatever they tested it’s probably proof of that, but such a small rocket and only 300 meters means that a lot of things were not really proven, because scale is a HUGE issue.
        Just ask Elon Musk / SpaceX, the Falcon rocket is fine, but Starship is horrible. And the difference is scale.

          That is not why starship fails. Starship fails because like everything that Elon does lately it emphasizes style over practicality. Starship is a very badly designed rocket that looks cool to Elon. Not unlike the Cyber truck which has been an abject failure in every way possible.

            My personal opinion is that it fails because SpaceX, like a lot of space startups, embrace a silicon valley coding mindset of ‘move fast and break things’, which results on them spending much more of their time and effort on testing than on design. Make a change, test, make a subsequent change, test. It gets them to a working prototype more quickly than legacy space/ defense companies. However, there’s no emphasis on modeling or design, which is problematic for solving complex problems that haven’t been solved for 50 years already.

            You are missing the point that size makes a difference. Obviously SpaceX has the technology to do what Honda did, but SpaceX can do ti with a real rocket.
            But they can’t do it with the bigger Starship rocket. Scale matters.

              And when SpaceX does it with real full size rockets and they explode scattering debris and chemicals everywhere, the nearby towns pay the price.

              Size is only a proof of logistics. Not tech. Physics don’t change fundamentally between 6 meters and 120 meters. You learn a lot from scale modeling without the added costs. Starship’s real challenge is actually the logistics necessary to fulfill the desired specifications and experimenting with engineering to reach the scale. The most innovative aspect of Starship would be orbital refueling, and they aren’t there since the thing hasn’t reached orbit yet. SpaceX problem right now is insisting on high turnover engineering, which doesn’t work at scale without heavy costs, because it is a logistic problem, not a engineering problem.

                Yes it does. Mass to strength ratio of structural components changes with scale. So does the thrust to mass ratio of a rocket and its fuel. So does heat dissipation (affected by ratio of surface area to mass).

                And I don’t know shit about fluid dynamics, but I’m skeptical that things scale cleanly, either.

                Scaling upward will encounter challenges not apparent at small sizes. That goes for everything from engineering bridges to buildings to cars to boats to aircraft to spacecraft.

        Imo it’s a good thing tho. Spreading our civilization across multiple planets is the only way to guarantee long long term success. Obviously we should also fix the climate change issue (and many others). But still, being spread across the solar system would give our species redundancy. An extinction event on earth like a large meteor strike would no longer be the end.

              Hypothetically, we could terraform Venus. At the very least, it shares a lot of the issues that we’re trying to fix on Earth, just dialled up to 11 - its main problems are that it’s way too hot, the atmosphere has way too much carbon in it (96.5% vs Earth’s 0.04%), and the atmosphere has way too much sulfur (0.015% vs Earth’s 0.00000002%, making the atmosphere highly acidic). So if for example scientists had an idea for causing a chain reaction in a planetary atmosphere that rapidly sequestered all atmospheric carbon but were worried about unknown strength or side effects, instead of testing it on Earth where it could kill us all, they could test it on Venus where any failures would have no serious consequences. And if it worked, not only would it mean that we fix climate change on Earth but we partially terraform Venus into the bargain.

              Venus has roughly similar gravity to Earth and has a ferrous core which could hypothetically be turned molten (and therefore ferromagnetic) to provide the same kind of magnetosphere that Earth’s core does. Mars has neither of these things and would therefore never be able to sustain human life naturally - Venus potentially could. On Mars, the atmosphere is just one of many obstacles. On Venus it’s THE obstacle. Solve the atmosphere, you solve Venus.

                Mars is the best option we have, which is why I mentioned that. Venus already has selfenforcing runaway global warming, and we can’t even land a probe there, because the environment is extremely hostile.
                Mars is by far the easier option.
