And with $160MM in funding at a $1.1B valuation? I don't know about their debt, but to get to LEO in 8 years on that little money is extremely impressive.

Other than whats publicly available, an interesting thought about this is how they were able to launch and create something within the highly corrupted political system. Every launch, stage and approval probably required sometype of bribe (even with the current governments focus on deep tech and scientific development)

The first, second and third stages all being solid rockets also means India now has a global-range ICBM, with only a little bit of modification needed to make it storable in a silo. Privately developed, but I would be astonished if the Indian military isn't well aware of this new capability.

India has developed ASAT, which is arguably more complicated that ICBM, agni series, they developed. India routinely understates ranges and appear non threatening. Agni5 and 6 are genuine ICBM, and with little tuning could reach anywhere in the world. India's bureaucracy and MEA is beset with gandhian mindset who try to avoid confrontations and minimise belligerence, opposite of PRC wolf warriors I guess.

It isn't because of some purported Gandhian mindset. It's becuase India is in a pacing conflict with China and Pakistan, whereas China is in one with the US and historically the USSR. Assuming the Chagos Archipelago dispute gets resolved in the next decade (India and France backs it's return to Mauritius because Mauritius' police and military leadership are under direct Indian control [0] but the US prefers Chagos remaining under British control because we are closer aligned), India has no need to explicitly publicize ICBM capabilities that extend beyond China or Turkiye.

Additionally, publicly stating India has ICBM capabilities makes it harder to land transnational mining deals [1] because then discussions with Australia, Brazil, Canada, etc adopt a nuclear proliferation dimension as well as placing a target on India's private sector because of SpaceTech and DefenseTech's dual use implications.

For those interested, just read a great book on this topic: When the Heavens Went on Sale by Ashlee Vance: https://www.goodreads.com/book/show/62050244-when-the-heaven... It profiles: Astra, Firefly, Planet Labs, and Rocket Lab

4 stages is certainly a lot more than most rockets, but most rockets don’t use solid rocket stages. Solid rocket motors are generally much more reliable/ simpler than liquid fueled stages, but they can’t be throttled or turned off early which makes it hard to achieve precise orbits. My guess is the extra stages allow for better control by carefully choosing when to light the next stage. The scout family of rockets ar…

Don't you need at least a little thrust ~40 mins later to circularize the orbit? Obviously solid rockets can't be relit. Could that be the use of the 4th stage?

Rockets are usually two-staged + satellites. The booster take it to outside of the atmosphere, then the upper stage puts it into a ballistic trajectory, and the payload does the circularization burn 45 minutes or so after the liftoff at the peak of the parabola.

Above is the basic semantics, and it can be further optimized, such as by extending battery power for the second stage to use it for circularization, inserting a single purpose satellite-like pusher device above the responsibility boundary at the top of second stage and payload satellite and calling it the third stage, or just adding actual third stage above second stage, etc.

Adding more and more stages improve performance per Konstantin Tsiolkovsky's rocket equation, but it'll add risk factors and also obviously add more dead weights in electronics and engines and support equipment, so 2-3 stages is usually the good balance between performance and risk/costs. You can have as many stages as you want if you think you can handle it.

Somewhat, but rocket engineering has some upward cost pressures that offset the savings from being in India: expertise is expensive even adjusting for the cost of labor (many staff are likely competing on salary with the rest of the world--rocket engineers/scientists are in high demand with lots of likely sponsors for immigration); aerospace materials/fabrication have a pretty global supply and patent chain even give…

> rocket engineers/scientists are in high demand with lots of likely sponsors for immigration I wouldn't be too sure about the immigration part, when even a software engineer hire for a defence/defence adjacent job requires jumping through a number of bureaucratic hoops of security clearances. Even the companies with deep pockets don't always get the best people in the world -- they just get the best people that HR c…

That's often true, but less true than it was a decade ago. Private, commercial space companies are a lot more numerous now. Sure, most of them have military contracts/oversight as well, but there are more opportunities with them that don't require military/government certification/authorization of immigrant hires than there were previously.

Also, there are plenty of space companies that aren't in the US/UK/China who are hiring (and more willing to work with non-domestic employees since they're playing catch-up), and plenty of companies in US/UK/China who employ contractors that aren't subject to the same hiring restrictions as the first-party/defense-contracted company.

There are a lot more specialized/high-expertise roles here than the ones critical to a nation's space program (or fungible with making weapons). Random examples off the top of my head include crew/life support expertise, launch facility engineering, LEO consumer telecommunications, and more. Space hasn't been fully commodified/detached from government interests--not by a long suborbital burn--but it's moving that direction enough to thaw out the ability to immigrate for work a bit.

> Only the third country to achieve this. What do you mean by this ?

Probably meant the third country with a private sector capability to launch rockets, US and China being the other two.

as opposed to New Zealand?

I have an AI generated podcast that tries to unearth some of the negative spin that develops around these amazing achievements. No surprise there was a spike in misinformation this week and I’m sure there will be more to come.

It can be hard when you are blindsided by negativity that seems to come out of nowhere. Hopefully this is helpful to us all https://rss.com/podcasts/the-narrative-networks-podcast/3017...
