Sometimes you see victories that feel bigger than a trophy.

Sometimes you know you’re witnessing the rise of a sporting prodigy.

Congratulations, @Anahat_Singh13, on becoming the World Junior Squash Champion.

You overcame not just your opponent, but the might of the Egyptian squash ecosystem, the strongest in the world today, built over decades and responsible for producing champion after champion.

These are the moments that tell every young Indian, that the summit is not reserved for someone else. It is there to be conquered.

We’ll be closely watching your journey….

Honoured to meet Hon’ble Prime Minister Shri @narendramodi ji along with my co-founder, Bharath.

From two engineers who started out with a bold idea which had low chance of success—to standing together with the Prime Minister after Vikram-1 became India’s first private orbital launch vehicle to reach orbit, it was a deeply humbling moment.

Your vision and bold reforms opened India’s space sector to private enterprise and empowered a new generation of innovators. We are proud that @SkyrootA could contribute to this national journey.

Committed to building from India, for the world. 🇮🇳🚀

Latest heat shield design looks great!

[Parimal @Fintech03]

If an Indian startup/defense firm wants to build rocket engines/satellite parts/surgical implants/advanced drone components, they need sub-micron precision metal parts made from heavy-duty alloys like Titanium & Inconel.

Historically, the ultra-precise 5-axis CNC machines required to carve these complex 3D parts had to be imported from countries like Germany/Japan/Switzerland at astronomical costs. To make matters worse, foreign suppliers face tight export controls on high-precision machining tech due to its dual-use potential in defense/missiles.

India had the engineering talent to design hardware, but was held back by a reliance on imported tooling & machining infrastructure.

A not so known startup Ethereal Machines is doing genuinely game-changing work for Indian deeptech & manufacturing, operating in a sector that rarely gets flashy headline attention compared to consumer tech.

Founded by Kaushik Mudda & Navin Jain out of RVCE in BLR, they hit on a fundamental bottleneck that was quietly crippling India’s hardware, aerospace & defense ecosystem.

Instead of just buying machines, Ethereal built their own multi-axis CNC machines from the ground up in India including their proprietary hardware, mechanics & complex CNC controller software. 🙏🙏

They built flagship proprietary machines like Halo, Aura & Nimbus that deliver sub 10 micron precision allowing intricate metal geometries to be carved in a single setup w/o manually repositioning the raw block.

Their early breakthrough was combining 3D printing (adding material) & multi-axis CNC milling (carving material away) into a single machine platform.

Instead of just selling machines, they run a massive 50K+ sq ft Smart Factory in Peenya, BLR operating 24/7. Startups in spacetech, drone tech, semiconductor equipment & medical devices can upload CAD designs & get aerospace-grade precision components delivered in days instead of months, cutting customer lead times by ~40%.

They became the 1st Indian company to win a CES "Best of Innovation" Award in Las Vegas for their hybrid manufacturing tech.

By controlling both the hardware & the software behind multi-axis machining, they give India's spacetech & defense ecosystem a local manufacturing fallback that cannot be disrupted by global supply chain shocks/export bans.

Top-tier deeptech investors like Peak XV Partners, Blume Ventures & Avataar Ventures backed them with major Series A & B funding rounds to set up a massive 300K sq. ft. mega-factory outside BLR.

Most people think of "Indian tech" as SaaS apps/fintech/q-com, Ethereal Machines is doing the heavy, unglamorous lifting, building the physical machine tools required to manufacture the rockets, drones, medical implants & chips of tomorrow right inside India. 🙏🙏

Yes, we assemble.

We don't build.

But it's changing now.

India's population beats the US, EU, and Japan combined.

We're still 7th in global manufacturing output. Screwing together an iPhone isn't manufacturing it, designing the chip, forging the steel, building the machine that builds the machine is.

That's the ladder we haven't climbed fully yet.

The good news is real: manufacturing GDP just crossed $450 billion, PLI has pulled in billions in committed capital, and semiconductor fabs are finally breaking ground on Indian soil.

The constraint was never talent, capital, or ambition.

It's time.

Every delayed clearance and every "let's form a committee" hands a decade to whoever moves faster.

The world is actively de-risking from China right now, this window doesn't stay open for the next committee meeting.

We're the answer on paper. We only become the answer in practice if we build like the clock is real.

Incredible... Future is clear to private space companies worldwide... Business --> Volume --> HighSpeed/Datacenter satellites.

Vast is expanding into high-power satellites. Introducing our new line of high-power satellite buses that leverage the technologies we’ve developed in-house for our Haven-1 space station and validated with the success of our Haven Demo mission. https://t.co/aITDUjQOzF

[AgniKul Cosmos @AgnikulCosmos]

Humbled to share that we successfully test fired 4 semi-cryogenic rocket engines simultaneously, as a cluster.

All the 4 engines are 3d printed as single pieces of hardware - designed and manufactured in-house at AgniKul Cosmos Rocket Factory - 1. As with all our propulsion systems, these 4 engines are also powered by electric motor driven pumps.

This test involved calibrating 8 pumps, 8 motors and tuning 8 speed control algorithms to work together in perfect sync to achieve uniform startup, steady state and shutdown performance across the entire system. As with the last cluster test, to the best of our knowledge, this is the first time such a test has been performed in India with semi cryogenic engines.

We are extremely grateful to have the opportunity to be building world class, original space technology from India, for the world with the support of @iitmadras @isro and @INSPACeIND

From here on, the addition of engines to our clusters will likely increase non-linearly. #Agnibaan #RocketEngineCluster #ElectricPumpFedEngines #Agnilet #SinglePieceEngine #3dprinting #RocketEngineTest #AdditiveManufacturing #Agnikul #AgnikulCosmos #StartupIndia #MakeinIndia #madeinIndiaForTheWorld

Elon Musk says one heat shield problem could kill Starship's reusability for years.

Starship is the most complicated machine humans have ever built.

The hardest part isn't the engines.
It isn't the steel.
It isn't even the explosion margin on liftoff.

Musk named the one remaining bottleneck.

"It's having the heat shield be reusable. No one's ever made a reusable orbital heat shield."

The shield does two impossible jobs.

"It's gotta make it through the ascent phase without shucking a bunch of tiles, and then it's gotta come back in and also not lose a bunch of tiles or overheat the main airframe."

40,000 tiles per ship.

Musk reframed the consumable problem through brake pads:

"Your brake pads in your car are also consumable, but they last a very long time."

The shield must consume slowly.
It must not require inspection between launches.

Musk on the current state:

"We have brought the ship back and had it do a soft landing in the ocean. But it lost a lot of tiles."

A soft landing is not reusability.

The bar is daily launches. One ship. Many flights.

Musk, on the gap that's left:

"You can't do this laborious inspection of 40,000 tiles type of thing."

The first reusable heat shield in history is the last gate to Mars.

Happy Birthday to Claude Shannon, known by many as the “father of Information Theory.” Shannon was an American mathematician and electrical engineer. In 1948, he published A Mathematical Theory of Communication, which effectively created the field.
