NASA's SLS vs India's space capabilities
- It's five-segment solid rocket boosters produce 3 times more thrust than India's current S-200 solid rocket boosters. We will either have to build bigger SRBs or put more SRBs on a single rocket.
- It's RS-25D/E main engine is more than twice in thrust over our current Vikas-X engine but similar to our under development SCE-200 engine which will come in service no earlier than 2026. We then can cluster engines just like NASA for launch but we lack a facility yet to test 4 engines together for such a rocket stage which will produce 7 to 8 MN thrust at once.
- It's second and upper stage RL10 C-3 cryogenic engines are although are just 50% against thrust of India's current CE-20 cryogenic engine. So we might not have to cluster as many engines on upper stage or even might achieve a higher payload capacity to TLI and TMI.
