Why Are SpaceX RAPTOR Engines 327 SECONDS Efficient?? Specific Impulse and Why It Matters

Do you hear about Specific Impulse (Isp) when you watch SpaceX videos, or listen to Elon Musk, and wonder what the heck it is--and why rocket engine efficiency is measured in seconds of all things?! Dr. Scott Walter and I break down Isp, explaining exactly what the units are (hint: they really aren't just seconds), and why Isp is so important when comparing rocket engines, but also why Thrust To Weight is so critical too. Hopefully by the end of the video, you'll have a good, intuitive understanding of Isp that you can use watching rocketry videos, and to bore your friends with at parties ;) Get 25% off Blinkist premium and enjoy 2 memberships for the price of 1!
