Elon Musk's recent thread calling Ambani as PM looks written by a "South Asian", and definitely not like his usual posting style. Excessive politeness, explanatory style with "so", starting a para with "Also". They are all a give away. Just read them for yourself. So it seems like a coordinated operation run by the same DS which attacks India's companies and capitalists, but now it's using Elon to make it political. I am at a loss to understand why Elon is getting influenced this way and letting himself be used to generate animosity with 1.4 billion people. Especially at a time when his companies are gaining acceptance and good traction in India. If he thinks half the Indians may support him due to politics, he's mistaken. For the small number of Indians getting carried away politically, and taking side with these foreigners interfering in India's sovereignty: Do understand Starlink is not being unjustifiably stopped. They are in the same regulatory approval status as India's Jio and Airtel. They have already got required licenses, setup required infra on the ground, and the distributorship to start operations once the final approval is given. Which is also expected soon along with Jio and Airtel. But Elon seems to be very frustrated that Starlink wasn't approved two years ago when he clearly could have monopolized Satellite internet in India. Now, with Jio and Airtel competing in parallel for satellite net, it is super tough for Starlink. So, as an Indian, it is important to understand while getting access to newer tech shouldn't be banned by GoI like pre-1990s India, it is also important to have a choice, competition, and clarity on security implications. The politicians who have suddenly done a 180 degree in taking sides with Elon are the same who were, two years ago, questioning India even considering allowing Starlink claiming "Modi sold out to Elon." We need to understand these sudden attacks on PM and India's companies are being done in tandem with other, on the ground, operations in India to destabilize and delegitimize the govt - which too has been completely organized via American social media. The same Elon talking about how India will benefit with Starlink, when it is actually being considered for approval, doesn't say a word about how China - which bans most American companies in strategic sectors and never even considered Starlink - will benefit from it. From this alone you can understand the agenda. India has enough services, network, the NDRF, and the Army, who can setup communication anywhere, to save our men women and children during a disaster. Beware of such white savior syndrome. Need to remind ourselves, East India Company came in saying "Indians will benefit from western trade."

Gloves are off now, Elon. Still no licence? Wrong. Starlink got its Unified Licence with GMPCS authorisation from the DoT in June 2025. You know that. Your own VP posted about it. Ambani is the real boss? Ambani's Jio lobbied for a spectrum auction. India gave you administrative allocation, the exact thing you asked for. Then you signed distribution deals with Jio and Airtel. If Ambani is blocking you, why is he your reseller? Five years of complying? In 2021 you took pre-order money from Indians with no licence at all. The DoT had to order you to stop and refund people. That was your first move in India. India's home ministry reportedly froze clearances after Starlink terminals showed up in Iran, where you aren't even licensed. Before that, our army pulled one out of a militant cache in Manipur. Your own company says talks are active and productive. So which version is true: the one your VP tells Delhi, or the one you tell 200 million followers? The spectrum rules were cleared last month and are headed to Cabinet. You're weeks from the finish line, and you're throwing a tantrum in public to rush a sovereign country's security review. India isn't a market you can bully on X. Wait your turn.
Starlink is licensed in over 165 countries and has spent five years complying with every single law and requirement of the government of India, so why still no license? Is Ambani the real boss of India?

What Skyroot pulled off this morning is genuinely stunning. Most people think a rocket's job is to go up. It is not. Going up is the easy part. The hard part is going sideways fast enough that you never come down. Let me explain this one idea in simple words. So orbit is not a height. It is a speed. Throw a ball. It falls. Throw it harder, it lands further away. Now imagine throwing it so hard that as it falls, the Earth curves away underneath it at exactly the same rate. It keeps falling forever and never hits the ground. That is orbit. So a satellite is not floating up there. It is falling around the planet, endlessly, because it is moving sideways at about 28,000 kmph. That is roughly 25 times the speed of a passenger jet. So a rocket does two jobs. It climbs out of the thick air near the ground, then it tips over and spends most of its fuel building sideways speed. Almost all of the energy goes into that second part. Now let's understand what Vikram-1 has achieved. It lifted off from Sriharikota at 12:05 pm today. The launch got held for 35 minutes at the T minus 5 minute mark because of a navigation issue. They fixed it and went. Fifteen to sixteen minutes later, the payloads were in a 450 km orbit. Fifteen minutes from a launch pad in Andhra to a stable orbit around Earth. :) The rocket is 24 metres tall, about a seven storey building. It is built from carbon composite instead of steel, which makes it far lighter, since weight is everything in this game. Every kilo of structure you save is a kilo of satellite you can carry. Now, Vikram-1 has four sections stacked on top of each other. Three solid fuel stages named after Dr Kalam. Kalam-1200 at the bottom, then Kalam-250, then Kalam-100. On top sits a small liquid engine called the Orbital Adjustment Module. As in most rockets, once the bottom stage has burned all its fuel, that huge empty tube is just a heavy metal shell you are dragging along. So the rocket throws it away mid flight. Lighter rocket, same engine push, faster acceleration. Then the next stage lights up. Think of a runner carrying three water bottles. He drinks the first one and throws it away instead of carrying an empty bottle for the rest of the race. Today all three stages fired and separated cleanly. First stage pushed it through the thick lower atmosphere. Second stage took over higher up. Third stage, the smallest, pushed it further. Then came the clever bit. The top module runs on liquid fuel, and its engine is 3D printed. Liquid engines can be switched off and started again. Solid fuel cannot. Once you light a solid motor, it burns till it is done, like a firecracker. You cannot stop it or restart it. So the liquid module is the precision tool. It fired for about six minutes, adjusted the path, and placed the satellites exactly where they needed to go. That start, stop, restart ability is what turns a rocket from a big firework into a delivery vehicle. But why this is a massive deal? Rockets have been doing this for years. See, in 2022, Skyroot flew Vikram-S. That was suborbital. It went up and came back down. Impressive, but going up is a fraction of the energy. Reaching orbit needs roughly 30 times more energy than just touching space. Today they crossed that line. India is now the third country in the world where a private company has put something into orbit. Only America and China had that before. Skyroot is a Hyderabad startup. Founded by Pawan Kumar Chandana and Naga Bharath Daka, both ex ISRO engineers who quit to build this. They raised $60 million in May. They have been test firing motors in Nagpur since 2020, one stage at a time, for six years. So, six years of quiet, unglamorous testing for fifteen minutes of flight. And they did it because ISRO opened up Sriharikota to a private company. IN-SPACe cleared the way. A government space agency handing its national launch pad to a startup is not a small cultural shift. Ten years ago that was unthinkable. The payload list is lovely too. Two cubesats, one from Skyroot and one from another Indian startup, Grahaa Space. A lab grown diamond from a Bengaluru company. A handwritten postcard from Modi Ji reading Vande Mataram, along with handwritten notes from the team and their families. Somebody's handwriting is circling the Earth right now at 28,000 kmph. :) Now, yes this was a test flight. They have said more test flights come before commercial launches, with up to two more Vikram-1 flights planned this year. First success is the hardest, but the real business is doing this again and again, cheaply and reliably. Still. A private Indian company built a rocket from scratch and reached orbit on the first try. Learn the name. Skyroot. :)
ORBIT ACHIEVED. 🚀 Vikram-1 Test Flight-1 has reached orbit. India's first privately developed orbital rocket has completed its final burn and injected its payloads into a ~450 km orbit, making India the third country in the world with private orbital launch capability. History is made. 🇮🇳 #Vikram1 #JourneyToOrbit #SkyrootAerospace

24 hours to lift-off. 🚀 Eight years ago, @SkyrootA started with just two people with an idea. There was no policy framework for private spaceflight in India, no real funding ecosystem for space startups, and we were taking on one of the world’s hardest engineering challenges. The odds of success seemed incredibly small. Today, India’s first privately developed orbital rocket stands on the launch pad, ready for lift-off. This moment belongs to every member of our team, our investors, the Government of India,@PMOIndia, @isro, @INSPACeIND, our partners, suppliers, customers, and everyone who believed in us long before this day. We have done everything we possibly could. Now we let physics do its job. Whatever tomorrow brings, every second of flight will teach us something invaluable. Reaching the launch pad and attempting an orbital launch is a landmark milestone for India—and an achievement only a handful of companies worldwide have reached. Every milestone we cross will advance not just Skyroot or India’s space journey, but the global commercial space ecosystem. Tomorrow, we take the next step. 🇮🇳🚀

Polarising, consolidating and banking on Muslim votes is victory of democracy, secularism in action, pluralism; consolidating Hindu vote in reaction is fascism, death of democracy, blow to secularism.

Better gut health starts with simple habits: 1. Eat more fiber: Whole foods keep your system moving. Supplement if not able to get naturally. 2. Use a stool: Lift your knees to align your colon for a smoother exit. 3.Leave the phone: Finish in five minutes or try again later. Avoid the strain. 4.Don't hold it: Listen to your body. Ignoring the urge leads to constipation. 5.Hydrate well: Water helps fiber do its job. Stay hydrated to stay regular. 6.Walk after meals: A ten-minute stroll triggers digestion and reduces bloat.

JUST IN: The United States has not built a new oil refinery in fifty years. Fifty. The last one broke ground when Nixon was president and oil cost $3 a barrel. Trump just announced a $300 billion deal to build one. The largest energy investment in American history. Port of Brownsville, Texas. Groundbreaking Q2 2026. Binding 20-year offtake agreement. Processing American shale crude. Thousands of jobs in South Texas. “The cleanest refinery in the world.” The lead investor is Indian. Reliance Industries, controlled by the Ambani family with a 50.39% promoter stake, operators of the Jamnagar complex in Gujarat, the largest single-site refinery on Earth, are the confirmed major foreign partner. Trump thanked them on Truth Social as “our partners in India, and their largest privately held Energy Company” for their “tremendous investment.” Now hold two facts simultaneously. India’s Reliance Industries is investing billions in an American refinery to process American shale oil for American energy dominance. India’s government, led by Modi, is simultaneously importing over 40% of its crude from Russia at war-discounted prices, rejected the US “permission” framing for a 30-day Russian oil waiver on 7th March (“India has never depended on permission from any country”), and continues buying Iranian crude via Chabahar port logistics. The same country. The same week. Building American energy independence with one hand. Buying Russian crude with the other. This is not hypocrisy. This is the Modi Doctrine operating at its highest expression. Multi-alignment means India does not choose sides. It chooses deals. QUAD membership for security. Russian crude for energy. Chabahar for Iranian access. Reliance capital for American refining. Israeli defence technology for military modernisation. Gulf remittances for 10 million workers. No formal alliance with any power. Maximum leverage with all of them. Every relationship is transactional. Every commitment is calibrated. Every contradiction serves a constituency. Trump needs the refinery because the Iran war just proved that 50 years without building one left America dependent on foreign refining capacity for products its own shale produces. The Strait of Hormuz did not just close oil transit. It closed the refined product supply chain that feeds American gasoline, diesel, jet fuel, and petrochemicals. Building domestic refining capacity is the structural response to Actuarial Warfare: if chokepoints can be closed by insurance spreadsheets, the only defence is not needing the chokepoint. Ambani needs the deal because Reliance’s Jamnagar complex processes Gulf crude that transits Hormuz. The same Strait that is mined, uninsured, and defended by 31 autonomous IRGC commands. Diversifying into American shale refining hedges against the exact crisis currently paralysing Reliance’s primary feedstock route. This is not philanthropy. It is the world’s largest refiner buying insurance that no P&I club can provide. The war created the crisis. The crisis created the deal. The deal was signed by the country whose Prime Minister was just given “permission” to buy Russian oil and told America it never asked. Fifty years. One war. One phone call. And the billionaire who builds it is from the country Washington cannot decide whether to sanction or celebrate. Full analysis here. open.substack.com/pub/shanak…

In the Kashmir Valley today, we have only one local TV news channel, ANN News. Before 2012, there were many local channels. Unfortunately, many of them provoked people, broadcast anti-country propaganda, glorified separatism, and reportedly received monthly payments for doing so. I once worked for one of those channels as an employee. One day, I mistakenly forgot to include news about a separatist leader in my bulletin. Because of that single mistake, I was terminated from my job. I tried to explain to them that I had no other source of income and that it was just a mistake. I apologized and requested another chance, but they did not listen. With tears in my eyes, I went home and told my mother what had happened. She comforted me and said, “Don’t worry, I am alive.” Her words gave me strength, but after that I went through very difficult financial times. I was the only earning member of my family, and the responsibility was heavy. For a long time I kept asking myself why this happened. I knocked on many doors and asked for permission to start my own channel where I could show people the reality and share positive news. But every door was closed because many people supported those existing channels. Eventually, those channels were shut down because of their anti-country propaganda. After many struggles, I finally succeeded in starting the first pro-country channel, ANN News. Even today, the struggle continues. Pro-separatist and anti-national elements still exist in different forms, including among some powerful businessmen and people in government departments. They try their best to shut down ANN News because we promote pro-India nationalism in the Kashmir Valley. Despite all these challenges, I continue my work with determination and hope that one day truth and positivity will prevail.

Read this. How a beautiful State like Karnataka is going to the dogs. Caste-based freebies,religon-based freebies plus a legal weapon at least at par with the SC ST Atrocities Act. Anyone who thinks the Congress is a viable alternative is either diabolical or delusional or both.
Bengaluru: Karnataka CM Siddaramaiah presents the State Budget at the Vidhana Soudha. He says, "Hajj Bhavans to be constructed at Hubbali and Kalaburagi for Hajj pilgrims. Waqf properties located in high-demand commercial areas to be developed under the PPP model. All gram panchayats in the state will now be named Mahatma Gandhi Gram Panchayats to immortalise the name of Mahatma Gandhi. The Rohith Vemula (Protection of SC/STs from Caste Discrimination in Higher Educational Institutions) Act will be implemented in all government, private, and deemed educational institutions to tackle caste-based educational and social oppression..."
