[Malay Krishna @Malay4Product]

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. :)

The science behind the Hydrogen train is wild.

It is a train that drinks hydrogen and breathes out plain water. No smoke, no diesel, no fire inside it.

Once you understand how that actually works, it starts sounding like magic that happens to be real.

Let me build it up from the very beginning.

First, what happened. On 17 July 2026, PM Modi Ji flagged off India's first hydrogen train. It runs between Jind and Sonipat in Haryana, an 89 km stretch.

India is now the sixth country in the world to run one, after Germany and a few others.

Now the science.

Every train needs power to move.

Old trains burned coal. Then diesel trains burned diesel. Both work by burning something, which means smoke and pollution.

Electric trains are cleaner, but they need those wires hanging over the track, and the power in those wires still often comes from burning coal in a power plant somewhere.

A hydrogen train does something completely different. It makes its own electricity on board, out of thin air and a gas.

No burning. No smoke. No wires needed.

Like I said, the science behind it is genuinely beautiful.

You need to remember one thing from school. Water is H2O. Two hydrogen atoms stuck to one oxygen atom. That is what water is made of.

A hydrogen fuel cell just runs that fact backwards.

Instead of splitting water into hydrogen and oxygen, it takes hydrogen gas stored in tanks on the train, and oxygen from the normal air around us, and lets them join back together to form water.

And here is the trick. When hydrogen and oxygen come together to make water, they release energy. In a fuel cell, that energy comes out as electricity.

So the machine is basically doing this.

> Hydrogen plus oxygen goes in.
> Electricity comes out to run the motors.

And the only leftover, the only waste, is water.

Clean water and a little warm air.

Now let me explain the fuel cell itself.

Imagine a sandwich. On one side you push in hydrogen. On the other side you let in air, which carries oxygen. In the middle there is a special thin sheet called a membrane.

That membrane is picky. It lets tiny bits of the hydrogen sneak through in one particular way, and that sneaking sets up a flow of electric charge. That flow of charge is electricity.

Once the hydrogen gets to the other side, it meets the oxygen, they hold hands, and they become water.

No flame. No explosion. No bang. Just a chemical handshake that leaks out electricity.

That is the part people find hard to believe. It looks like nothing is happening, and yet it is powering a 10 coach train.

Now why this particular launch is a proud engineering moment.

Most hydrogen trains in the world are tiny. Two or three coaches. They run on short countryside routes carrying a few hundred people.

India did not build a toy. India built a 10 coach trainset that can carry around 2,600 passengers. The design has two power cars, one at each end, holding the hydrogen tanks and fuel cells, and eight passenger coaches in between. It is built to run at up to 110 kmph.

That is the biggest, or one of the biggest, hydrogen train efforts anywhere.

We did not just copy a small foreign version. We scaled it up to Indian crowd size.

And it was built here in India.

The coach came out of the Integral Coach Factory in Chennai. A dedicated hydrogen plant was set up in Jind to make and fill the fuel.

This is Make in India in the truest sense, not an imported train with a sticker on it.

Now, hydrogen is not free magic. There is a catch, and it is important.

To get hydrogen gas, you have to make it, usually by splitting water using electricity. If that electricity comes from burning coal, then you have just moved the pollution from the train to the power plant.

It is only truly green if the hydrogen is made using solar or wind power. India is building that, but we are not fully there yet.

Hydrogen is also expensive to produce right now, and the tanks and fuel cells cost a lot. So for the next few years, this will be pricier than a normal train.

This one route is a pilot. A test. A place to learn before spreading it wider.

And storing hydrogen safely needs serious engineering, because the gas is very light and very flammable. To their credit, the train has multiple safety layers that sniff for leaks, heat, flames and smoke.

So, this is not the finished revolution.

It is the first real step, and a genuinely big one.

A country of 1.4 billion people just built one of the largest hydrogen trains on Earth, that turns a gas and air into electricity and gives back only water. :)

Many of us want accountability from the govt for the NEET 2026 paper leak that forced 22lakh students to take one of the country's toughest exams twice. The stress of the re-exam forced 15 students to take their own life!
Yet the same many of us can't bring ourselves to support CJP. Not because the cause is wrong, but because the messenger is. The optics, the political baggage (AAP) & clubbing these students' fight with unrelated causes have diluted, even made a joke of a serious injustice.
The CJP movement lacks the credibility that a protest the NEET students deserved.

[Awasthi @Awasthiii18]

I no longer place faith in such notions.

Our civilization endured because those who forged them possess the strength to defend their way of life against any one who would dare threaten it. Sadly that is no longer the case, so decline is no longer a risk! it is an inevitability.

[Ankit Dubey @ankitdubeyji_]

A mother's frustration reached its breaking point today.

Her son scored 650 marks in his very first NEET attempt, but after the exam was cancelled, he slipped into depression. She has been attending the protest for the last two days, hoping the concerns of NEET aspirants would finally be heard.

She later said that the protest barely addressed the issues faced by NEET students. What disturbed her even more was hearing someone raise the slogan, "Bharat hamari maa hai, to Bharat ka baap kaun hai"? That was the moment she decided to confront Sonam Wangchuk, telling him he was surrounded by the wrong people.

He reportedly asked her to speak with Abhijeet Dipke, but she couldn't find him anywhere. Later, she came to know he was staying at a five-star hotel, which further angered her.

In protest, she threw ink at him and accused him of misleading people, saying, "You cheated us. You gave us false hope." She also claimed that some of his supporters surrounded her and shouted, "Maro, maro."

Whatever your views on the protest may be, I sincerely hope she stays safe. A mother fighting for her child's future deserves to be heard, not intimidated.

Great day for Indian technocrats.

A young group of engineers chose the harder road. Instead of taking comfortable careers abroad, they stayed back, built a world-class team in India, and created a space-tech company that's attempting to launch India's first privately built orbital rocket.

This is more than a rocket launch. It is a statement that Indian engineers are no longer content with contributing to global innovation. They are ready to lead it.

The coming decade belongs to builders. The era of Indian engineers has truly begun.

Here’s the story of Ranjish. 💔

He was 38, a bus conductor. He married the girl he loved and had a daughter.

Two years later, his wife left them both and moved to the Gulf. There she found another man, fell in love, and abandoned Ranjish and her daughter.

Ranjish raised his daughter alone for 8 years, pouring every drop of his love and strength into her.

Then his ex-wife filed a case. He fought desperately for the child he had brought up with his own hands. But the court sent the daughter to her mother and “stepfather.”

He lost his wife. Then the system took his daughter too.

Completely broken, Ranjish took his own life.

Apparently, men seem to have no rights in this society. No one sees their pain, their struggles, their silent battles.

Pranamam Ranjish 💐

[Malay Krishna @Malay4Product]

Let me explain what this whole fight is about, because it is very different from what the tweet by the Japanese official makes it sound like.

Back in 2015, India and Japan signed the Mumbai to Ahmedabad bullet train deal. 508 km.

India would use Japan's Shinkansen trains and Shinkansen technology. Japan put up a massive soft loan, covering most of the cost, at almost no interest, 0.1 percent, to be repaid over 50 years.

On paper it sounded amazing. Cheap money, world class trains.

But every such loan has a catch. Cheap Japanese money came tied to buying Japanese things.

Their trains. Their coaches. Their signal system. Their price, largely on their terms. That is normal. No country lends billions out of pure love. They lend to sell their own industry.

Then two things went wrong, and this is where his anger comes from.

One, the price.

The Japanese Shinkansen trainsets turned out to be extremely expensive. India felt it was being overcharged for the rolling stock. So, talks hit a wall.

Two, the timeline.

The newest Japanese trains, the E10 series, would reportedly only be ready for India around 2032. India did not want to sit on a finished 1.08 lakh crore track with no trains to run on it.

So India made a call. And this is the part I am proud of.

Instead of waiting and overpaying, India decided to run its own trains first. BEML in Bengaluru got an order to build indigenous high speed trainsets at about 866 crore each, designed to run at 280 kmph.

India will open the line with Indian made trains on the Surat to Vapi stretch around 2027, and bring in the Japanese Shinkansen later.

And the signal system, the thing he is bitter about, India switched from Japan's DS-ATC to the European ETCS Level 2 system.

The same family already used on the Delhi Meerut rapid rail. That is what he means by Japan being excluded from the signal system. India looked at the Japanese option, found it too costly and too slow, and picked a different one.

Now let me be fair, because I cannot be blind just because I am pro India.

He is not lying about everything.

India is genuinely a tough, frustrating negotiator. We change our mind. We push for our own interest till the last minute. We renegotiate things others thought were settled.

To a Japanese official raised on politeness and fixed agreements, this feels like betrayal.

But flip it around and look at it from our seat.

Our job is not to protect Japanese honour. Our job is to get India a bullet train at a fair price, that runs soon, and that builds Indian factories in the process.

On all three, changing course was the right call. Waiting till 2032 and overpaying for imported trains would have been the polite choice. It would also have been the stupid choice.

There is a bigger thing hiding under his frustration, and I think it is the real reason for the anger.

For decades, the deal was simple. Rich countries gave loans and technology, and poorer countries said thank you and bought whatever came bundled with it.

You took the money, you took their trains, you did not argue.

India argued. India took the loan, then insisted on its own trains, its own signal system, its own factories getting the work. We used their money to build our capability instead of just renting theirs.

That is what stings them. Not that we were reckless. That we refused to stay the junior partner in our own project.

I will give the Japanese side genuine credit.

Their engineering is world class. In 60 years, the Shinkansen has never had a passenger death from a derailment or collision.

That safety record is worth respecting. Their frustration with our chaos is also probably fair on a human level. Working with India can be maddening. Anyone who has managed an Indian project knows this.

For me, the real issue is what’s in it for our country.

India has the track. India is building its own trains for it. India picked its own signal system.

India got a 50 year loan at almost zero interest. And India will still get the Shinkansen later, on better terms than the original bundle.

If that is what Indian recklessness produces, I will take it every single time.

Be tough. Be a nightmare to negotiate with. Just make sure the country wins at the end of it. :)

In my career, I exported over INR 1500 crore worth of goods and close to 40,000 tonnes of material across the globe. A paperwork clerical mistake worth around 1 crore and a field recall of just 700 kg cost me more pain and money than I can explain. Some nights I asked myself why I started this.

[Military Observer @TheMilObserverr]

🇮🇳 India just built a radar that outranges anything currently flying on the Su-30MKI.

It's called the Hawk-I-2700, made by Chennai-based Data Patterns.

It can spot a large aircraft from 350 km away and lock onto something as small as one square metre from 200 km out.

That's a serious upgrade over the ageing Russian Bars radar still sitting on India's Sukhois today.

It's now up against DRDO's own Virupaksha radar for a spot on the Super Sukhoi upgrade.

The difference is that Hawk-I-2700 wasn't built by the state. It was built entirely by a private company, from scratch.

If it gets picked, it won't just give the Su-30MKI a second life. It'll prove India's private sector can build the kind of radar that used to only come from government labs.
