having a well written bio is cringe



🚨 Byju’s, once India’s most valuable startup, has gone from a $22 billion valuation to bankruptcy. What went wrong?


The full Pad-2 Deluge system has been activated for the first time. That's insane!



Four things to realize: 1. Nuclear electric propulsion does nothing for Mars ascent. 2. Low Mars orbit to Earth transfer needs only ~2.5km/s, which you can do easily with chemical propulsion (with methalox it's only half propellant, with hydrolox, even less). 3. PICA-X is good enough for direct entry from Mars return. 4. Low twr NEP spiraling out of Mars orbit, trying to do a quick run to Earth, and then spiraling into Earth orbit explodes the delta v budget. Combined with its higher dry mass, the performance advantage gets just about wiped out. All you're left with is a more expensive, lower TRL solution that takes longer to develop.








the biscuit we used to bring in suitcases from europe is finally available in india 😭
