We just installed some CNC machines at the Engine and Stage integration facility at Astrobase Space. Action >> Hype. The objective is to reach a stage where we can produce 50 FFSC rocket engines annually with 80 Tonne thrust each. This capacity plus Reusability allows Astrobase to deliver 200-500... show more

🚨 BIG: 🇮🇳 India to soon join the global race for SpaceX-like reusable rockets Chennai-based space startup Agnikul Cosmos has announced Mission-02, a bold plan to attempt India's first recovery of an orbital-class rocket booster by a private company. The mission aims to safely recover the booster for refurbishment and reuse, while repurposing the upper stage into a functional in-orbit platform instead of letting it become debris. This is a major step toward reusable launch vehicles that can significantly reduce costs and make satellite launches more affordable and sustainable. Agnikul is already a leader in 3D-printed rocket engines that can be produced rapidly. It is now advancing reusability technologies, backed by multiple patents from 🇮🇳 India, the 🇺🇸 US, and 🇪🇺 Europe. With support from ISRO and IN-SPACe, this progress highlights the rapid growth of India's private space sector. Alongside recent private orbital launches like Skyroot’s Vikram-1, the country is building strong self-reliance in space technology. A proud leap forward for Made in India innovation. 🇮🇳

🔥🛢️The Slavneft-YANOS oil refinery in Yaroslav is burning heavily following another overnight drone attack. With a processing capacity of around 15 million tonnes of crude oil annually, it is one of the five largest in the country. Despite repeated attacks in recent months, previous strikes failed to disable the facility for any prolonged period. There is now a real possibility that the attack could finally force the refinery to suspend at least part of its operations for some time.

The Sabotaging Practice of Over Supply and Sameness in the NFT Space. The current zeitgeist of the NFT space is that the same artists are doing the same kind of work five times a year, with project after project leaving a trail of disappointment and discontent among collectors and all of us watching in disbelief as huge resources are extracted from the space over work that feels like it could be left as an "artist study." I understand that you can do what you want with your money as collectors, but we are killing the whole space with this incestuous practice. No artist is that prolific to be able to do 5 collections of 100+ pieces each every year and actually deliver innovation and some kind of creative evolution. Of course, they can pretend play that the work has something new, but there is no precedent nor proof that that has ever happened in the speed that it happens in the NFT space. Again, people are free to through away their resources on whatever they want but with this way of doing things, we more and more are going to start seeing the consequences. Oh! There are consequences? Yes. Maybe unintended, but there are. Let's see. Let's start with the loss of belief in the NFT space as somewhere where emerging artists can come and find support for their experiments. Why even bother to bring experiments, innovation, and new ways to think of art on the blockchain if the same people have all the collectors hypnotized with their magical flutes? Why even try to come to a space where taking risks and challenging the status quo (the mission of art!!!) is overlooked? This makes the NFT space a social club and not a space for art. I guess it is fine, but IMO it is a recipe for disaster. New collectors stay away because the art will slowly but surely become stale and un-challenging. Why even bother to come and see what is happening here if you can't, as a collector, see new weird and up-and-coming artists? The amount of noise emitted by the same artists doing the same art over and over, drowns out any new voices. Again. A recipe for disaster. The NFT space is becoming a space of disappointment and doubt. We think that collections going to zero one after the other, over and over, is not damaging? I feel we are kidding ourselves. Disappointment piles up, and again, the people who will hurt are the emerging artists, the new blood, the ones who are willing to risk the most and, in return, put fire in this cold space of sameness. I love this space—don't get me wrong—it has changed my life, and I believe it has a ton of potential, but things need to change for it to become a beacon of light in art. But we need to support new voices. We need to support new ideas. The challenge is huge. I hope to contribute all I can to this change. I hope more and more see how exciting it is to go out and try to discover what else is out there and move this space forward. But again, I understand the leaps of faith needed, but if there is a space that is based on that, it's the NFT space...so there is hope. We will see. 📺by Boldtron

GM. Do you want to escape every day life and experience the paradise of Puerto Rico? Be close to the beach, mountains, jungle, and great food? Excited to officially announce what rae rae and I have been working on for MONTHS… your new tropical getaway Casita de Cruz! We paired this experience with its own NFT valid for a three day stay redemption. The problem we have seen with NFTs like this is that the consumer is purchasing on a whim and a prayer. Either the place isn’t ready, space isn’t acquired, or just plain will never happen. Casita de Cruz is ready to go! You can book your stay now, no waiting for a turn around. We designed this space for people who are wanting to disconnect & recharge. Nestled in nature, this is your time to retreat, tap into self, the earth, & resurface fully renewed. This has been a labor of love & we hope that you can feel every bit of our passion poured into this space. We will be launching this token later this month and will be doing AMA spaces plus some fun giveaways. RT and tag someone who you want to experience this with!

"Automate Earth, Enable Space" Over the last two weeks, we've explored how robotics can transform the terra-space industry. We're incredibly grateful to Meagan Murphy Crawford , Jim Thomas , and Sean D. Graham for introducing us to key industry leaders and facilitating our tour of the US Space Force facility at Cape Canaveral. With a deeper understanding of the space sector’s needs, we see a growing opportunity for Earth-based robotics to play a pivotal role in supporting space advancements. The intersection of robotics and space is not just a possibility; it’s essential for the future of both industries. #RoboticsForSpace #TerraSpace #AutomateEarth #FutureOfSpace #InnovationInAction #Robotics NVIDIA Robotics

we played PAWSA “the groovy cat” at an EDM stage in 2018. I think given how recently PAWSA skyrocketed to the mainstream, this is just proof to stick to your guns, and that your art will eventually find the people it’s meant to connect with.

I want to make this clear to you: the area they describe as a “safe zone” is in the west of Gaza, but look closely , there is no space at all, not even on the seashore, as the entire place is packed with tents. Where are people supposed to go? Are we expected to live in the sea? How can they do this? What kind of logic is this, telling us to head west while they know very well that there is no space there?

Just two months ago, we were on the verge of letting go of a customer that we had been serving for more than two years. The prices were super competitive as they were procuring these springs from China. According to our cost calculations, we would have to sell them these springs at our breakeven price point. We would not be making any profit from their orders. The volumes were huge and we decided to take up the challenge. In manufacturing, one of the very important metric that your product cost depends on is cycle time. The speed at which we are able to process that part within the desired tolerance. Higher the speed at which you can manufacture, lower the cost of making that component. We could only manage 150 pcs/minute on our imported machines. At this speed, it was unviable for us. It would only make sense for us to continue if we were somehow able to manufacture this spring at a minimum of 200 pcs/minute. We were far apart and it seemed we wouldn’t be able to reach that goal. We were on the verge of giving up after two years of persistent effort in increasing our speed. Today, we manufactured that same spring on the CNC machines that we built in-house at a whopping 220 pcs/minute! We went from almost letting go off that customer to now asking that very same customer to increase our order volumes! First video is our imported machine at 150 pcs/minute. The second video is our in-house machine at 220 pcs/minute.

♾ Credit System Integrated + Vision Announcement♾️ NFINITY AI is going to become a household name in both Web3 and the AI space. We keep repeating the same thing over and over again, and we will do it again today: ♾️“A New Standard” ♾️ Our team is filled with experts. Years and years of experience comes together in this project. Not only do we understand Web3, but we also understand Web2. We analyzed, executed, and tried a lot of different approaches. We made dozens of case studies and came to one conclusion: Web3 needs a new standard. Web3 needs Web2 copywriting. Web3 needs non-greedy developers. Web3 needs communication and an understanding of human psychology at the highest level. Web3 needs speed and patience. Web3 needs timing. KOLs aren’t bad; they just have to be managed correctly. Web3 needs common sense. All that crazy 1000x stuff is not going to bring us great tech. It’s not providing us with the things we need. The short-term minded rule this place, while long-term people should be on top. And that’s what we’re doing. We like to take time to get to know our core community. We want to build with smart people, people who want to invest but also contribute. We want to build with the top 0.1%. The plan is simple: We’re building out an excellent idea. We start with Stage 1 and perfect it with the core community. We build out to Stage 2 and bring it to the masses. And when we arrive at stage 3 and start exploring the possibilities behind an L2... Well, then it’s time to shine. Build together with us. To Infinity And Beyond.

More Batteries vs. Submarines Now that the German TKMS and the French Naval Group have massively adopted lithium-ion batteries, following the Japanese lead, this is consolidating as a major trend, just as I had predicted. The next stage will be solid-state batteries, and at that point, we'll essentially be discussing only speed and submerged endurance in comparison to nuclear submarines. Since solid-state batteries are lighter, they will allow for a greater number to be installed, freeing up space for more powerful propulsion systems. Naval Group has already sold a version of the Scorpène to Indonesia capable of remaining submerged for up to 80 days. That's with lithium-ion batteries. Imagine what this could exceed, more than double, with solid-state batteries. In practical terms, a more powerful engine combined with solid-state batteries in the proportions that Naval Group is now using in the Scorpène would provide three times the speed, meaning something like 10–15 knots at constant speed while maintaining around 50 days submerged. This would give a range of 40,000–50,000 km, requiring less than one hour on the surface for a fast recharge. For speeds above 25 knots, simply adding more batteries and a better engine would suffice, as the solid-state system has high power output. All this at 15–20% of the cost of a nuclear submarine. And if the choice is to power the batteries with a micro-reactor, it would cost 25–35% of a conventional nuclear one. Then someone will say: “But a nuclear sub can stay submerged for years.” That makes no difference at all, since even with around 60 days of endurance, the crew still needs to surface to resupply provisions. The big advantages remain: battery-powered subs are superior in silence, and speed can be addressed with larger battery packs.
