I have been saying some of this for years. SpaceX customers are subsidizing Starlink. With traditional launch, costs are simple. Fixed costs (infra, labor...) + Cost of rocket / $$$ from the launch. The fixed costs get divided by launch cadence, so they are huge for 1 launch per yr, but not bad for 10/yr. With reuse, your launch cost breakdown gets funkier. You still have the fixed costs, but now you divide those by 100+ instead of 1 or 10. Add in the less quantifiable increase in competence that comes from doing this 2/wk instead of 2/yr. Now, you get to amortize the rocket over its lifetime. With that though, you have to add some stuff back in. You add refurb costs, which include spare parts and labor. Do you get better at that over time? That seems to be the case, and spare parts on a 23X flown bird certainly beats a new bird! So, I can have 1/20 rocket cost + refurb? That's only something knowable after it has been retired. So, 23? 30? We don't know yet! Of course Falcon 9 isn't fully reusable. The upper stage is expended, and I've recently heard that 2/3 of their cost is due to the upper stage expenditures. So, what does a launch cost SpaceX? At this point, it costs something like this: (Fixed costs/100+) + ((booster + fairing/20+) + (Refurb )) + (Expended upper stage) + (Propellant, which is usually 1-2% of launch cost, so it ordinarily doesn't even factor) And here's the kicker. They have no reason to lower price until a second player enters the arena at a similar price point. It would be destructive to their own profits and the absolute razor edge Margin model they are playing with Starlink, but it would also be destructive to any current or future competitors. Of course Starship will be different. The rocket will be cheaper/kg of payload, it will be fully reused and the unit lifetime will be higher.

[Select Committee Hearing on Drones] Edited out the relevant drone bits. I actually like the idea of taxing Chinese drones and using that as a subsidy for American made ones. Why? At least there's still competition and American manufacturers continue to experience innovation from the Chinese which will lead them to improve their own products. Otherwise America risk falling even further behind. One thing I notice is that somehow US government seems to feel public safety is part of national security but regular public officers dont think so. Which is why many of them are very vocal about the ban. Full version here: https://lnkd.in/gPs9qZjp

All technology seems like magic once it works. The question is how do we tell if some goals are too outlandish? Here is a simple template: > Does it fall within the bounds of physics? > Will a first principles check show feasibility? - even if the odds seem slim. > Do you have a team from all disciplines needed to solve this? It takes imagination and courage to attempt breaking the norm. SuperHeavy booster catch envisioned in this video (Credit : Space.com & SpaceX) checks all three boxes. Catching the Superheavy booster sounds crazy but, at one point, so did landing a F9 booster after an orbital launch. It will be exciting and rewarding to reach this goal. #Spacex #Spacetechnology #Starship #rockets https://lnkd.in/g7yq_yiV

We report the first hybrid matter-photon implementation of verifiable blind quantum computing. We use a trapped-ion quantum server and a client-side photonic detection system networked via a fiber-optic quantum link. The availability of memory qubits and deterministic entangling gates enables interactive protocols without postselection—key requirements for any scalable blind server, which previous realizations could not provide. We quantify the privacy at ≲ 0.03 leaked classical bits per qubit. This experiment demonstrates a path to fully verified quantum computing in the cloud.

OL-78 of 2024 🇺🇸🇳🇿Rocket Lab 📢 🚀 #Electron Beginning Of The Swarm 🗓️ 24 Apr 2024 🕰️ 03:30 IST / 22:00 UTC (23 Apr) 📍 LC-1B, Mahia Peninsula in #NewZealand 🛰️ ACS3 from #NASA & NeonSat-1 from #KAIST NASA - National Aeronautics and Space Administration's ACS3, a technology demonstration of new materials and deployable structures for solar sail propulsion systems that use sunlight to propel the spacecraft. Much like a sailboat is powered by wind pushing against a sail, solar sails employ the pressure of sunlight for propulsion, eliminating the need for conventional rocket propellant. The mission plans to test the deployment of new composite booms that will unfurl the solar sail to measure approximately 30 feet per side, or about the size of a small apartment in total. Deployer made by Exolaunch 2.NEONSAT-1, is an Earth observation satellite with a high-resolution optical camera designed to monitor natural disasters along the Korean Peninsula by pairing its images with artificial intelligence. NEONSAT-1 is the first satellite developed under the NEONSAT program by Satrec Initiative Co., Ltd. and Korea Advanced Institute of Science and Technology, Korea’s leading university in science and technology. #Rocketlab #NASA InfoGraphic by ZetaGravit

Leading space technology company Sierra Space, best known for its Space Plane, has now developed a new idea that promises to deliver freight anywhere on Earth within 90 minutes of receiving a request. It is said that this technology will transform space logistics. How does it operate? The system would entail manufacturing supply units that would contain cargo. After that, these units would be sent into orbit and kept there for a maximum of 5 years until someone requests the cargo. The orbiting unit will execute brake burns to slow down and deorbit towards the earth's surface under gravity as soon as the delivery request is received. A thermal shield would be fitted to the unit to shield the cargo from the extreme heat and plasma produced during reentry. The shield will separate in the last stage, allowing a parafoil with a rudder to open and guide the unit to its intended landing location. The company wants the unit to land no more than 100 meters from the delivery location. What worries people about this technology? Without strong legislation, the technology's application in humanitarian aid efforts would be restricted, even though its goals include both supplying weapons to combat zones and aiding in relief efforts in disaster-prone areas. It may be difficult for the general public, particularly in rural areas, to locate and handle a landed space payload in the case of a natural catastrophe, as communication lines are typically the first to be damaged. The government or other administrative body may view the space payload as a possible threat if it carries weapons or warheads and is providing relief assistance to areas affected by war or other man-made calamities. No nation dealing with such a situation would take the chance of permitting an unidentified foreign body to set foot inside its boundaries. Therefore, even though the technology has enormous potential, it does not seem to be practical enough to be achieved. There's a concern that this technology will spark a rush to militarize space. As soon as one government begins to store weapons in space, other spacefaring nations will soon be competing to store their own arsenal. Furthermore, it wouldn't take long for simple weapon storage to give way to the storage of nuclear bombs in orbit. What benefits does technology offer? It is unfounded, even though it may appear at times that there are more hazards associated with technology than advantages. This concept has the capacity to completely alter the field of space logistics. The system is not merely for delivering supplies; it can also be used to return the space station's modules and experiments from orbit. Moreover, the technology can be utilized for returning small satellites to Earth for data collecting and reuse (in whole or in part). Way forward? Legislation restricting the militarization of space can be introduced by space-faring nations without impeding the advancement of technology. #space #spacetourism

Really great article on Space! Highlights Rocket Lab and their mission of small launches their Electron rocket has filled. It goes on to discuss the Neutron that is a medium lift vehicle. Rocket lab focuses on the taxi service where it takes individual payloads to specific orbits, but the new Neutron rocket is meant to compete with SpaceX and its Falcon 9. The article further discussed start ups, such as Relativity Space and ABL Space Systems. I was quoted around the maturity of businesses in this segment and discussed M&A activity. I highlighted that, "... for a company to be a consolidation target it needs some enterprise value; it needs sales and employees and contracts." I further went on to say that, "... those pure-play space companies, they are going to have a harder time because it is a slower cycle, versus a company that gets into space with a diversified book of business and will probably be more successful." #aerospace #space #mergersandacquisitions #thefactorydoctor https://lnkd.in/gsNrw2cA

Is the proliferation of drones confusing customers? Industry experts have predicted that within the Defense & Military market alone that drone platforms will go from several hundred types to over 10,000 platforms satisfying diverse needs and following the “miniaturization” curve over the next 5-7 years. That is a strong statement for the drone Industry, although it also reinforces how difficult it will be for customers to distinguish and differentiate drone-related products and services. The key is continuing to look for those drone providers that focus on solving problems and designing their drone solutions to fit critical, applications requirements. EuroLink grew-up in the Technology field – with decades of experience learning and meeting the demands of mission-critical, program needs. This experience has been translated into EuroLink’s Beluga™ family of mini-drones – which was designed from the user perspective first, leveraged and applied lessons learned from the Aeronautical Industry and uniquely applied a Bio-inspired approach to support its design and breakthrough blade/propeller technology resulting in the “Silent Drone.” Here is a published article from Unmanned Systems Technology (UST) highlighting Beluga’s application for ISR target applications: https://lnkd.in/dZsgwNVQ Intriguing and supported by a challenging Roadmap to continue extending Beluga’s™ capabilities and providing advanced UAV, UGV and UUS products.
