- mayamaRegarding Indian private space sector, In addition to skyroot solid rocket, following are noteworthyAgnikul is planning to launch semi-cryo kerosene rocket pretty soon. Their engine is 3d printed and use electric pump fed 25kN small engine. Planning to launch 4 clustered engines as first stage and already did suborbital test, with some parachute splash down reusability claims.Astrobase is recent entrant. With decent funding and former ISRO scientists as core team, developing 800kN FFCS methalox engine. FFCS is called holy grail of liquid engines. They have acquired largest metal 3d engine and planning VTVL 1st stage reusability
- itissidThere is just so much that can go wrong with rocket launches if you do cursory reading about these things. A few random examples: The lowest stage cant just be "turned down" or modulated because they work by burning an inner solid rubber lining that's like an annular cylinder. The first three stages are roughly doing the job sequence: `lift off the ground -> reach target altitude -> reach target orbital velocity` and each stage is modulated for atmospheric pressure, gravity. Another limit is you can't really design it for a human in the middle(like a jet plane), so the rocket's computer needs to do everything, and when the rocket's pitch or yaw or roll(in a manner of speaking) go off beyond a nominal range its game over.ISRO has a very good track record of launching rockets with solid state engines. I do wonder if almost all of their expertise was used for the first three stages(and they are not 3d printed)? And how much more difficult it is to make the last stage as compared to the first three, which as I understand, was the stage designed and tested by skyroot itself(manufactured by Wipro 3D).
- zbentleyAnd 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.
- sidcoolOnly the third country to achieve this. Kudos.There's another startup trying reusable rockets.
- jdiez17Extremely strong performance from India’s Skyroot with their Vikram-1 rocket. I can say that many in the space industry are looking for new launch capacity to LEO.
- ambicapter4 stages feels like a lot of added complexity for your first launch. I assume it gives you more performance margin to drop weight/stages more often?
- bovermyerThat's pretty cool. The phrase "3D-printed engine" stuck out to me as neat, too.
- walrus01The 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.
- vjsrinivasIndia's space work often went under the radar. Im glad they're getting the success and attention they deserve.
- ghm2199A small but bright light in an economy where manufacturing jobs are hard to come by (https://archive.ph/Haj8n).
- ColdStreamFantastic news! Always good to see others manage achieve great things.
