How SpaceX Is Upgrading Raptor To Be The Ultimate Rocket Engine!

Your ability to bring aero-spike engines into every conversation is astounding😂

Didn't we learn anything from Jurassic Park?! Breeding Raptors is dangerous!

2 everyday astronaut videos in 1 week? What a treat! Keep it up Tim!

Hi, Tim. I try to watch all the SpaceX-focused channels. I think yours is the best written. You have less speculation and grandstanding than some others. Your vids are packed with information that is timely and focused. Thanks for sharing! Stay healthy!

No one on the Internet, let alone anywhere else on YouTube, explains rocket engines as well as you do. We are very lucky to have you explaining things to us, incredible video and incredible work!

Raptor 2 is so CLEAN! Izan Ramos' models are incredible.

I suspect that Raptor 2 is much more mature than Merlin after a similar time spent refining the design. After all, this isn't their first Rodeo! So I'm thinking they may get another 20 to 30% improvement, but not double from their current design.

Tim, when you mentioned a 1:1 thrust to weight ratio, I was reminded of Astra's Rocket 3.3 LV0006 which had an engine failure moments after launch. The four remaining engines had enough thrust to keep the rocket flying, clearing the tower horizontally, but were unable to increase altitude until after some of the propellants had been consumed. I fully expect for the Raptor 2 of today to not be the final version of the Raptor, but there not be as large an increase in thrust as there has been between the first Merlin 1A and today's Merlin 1D. I can see a chance of the 33 Raptor 2s on the bottom of a Booster to function as a single extremely large aerospike engine.

Man Spacex is leagues ahead of anyone.

I think the best example of the TWR issue was the Astra (?) launch that traveled sideways after losing an engine until it burned enough propellent to get better than 1:1 at which point it started to gain altitude.

Tim, you and youtubers like you, are the future of journalism. I have no doubt you could be a rocket engineer (or lead a team of them) yet you have the ability to explain it to the masses. True journalism that is needed now more than ever. Thanks for your hard work!

I should also added that many parts were transferred to the vehicle, similar to jet engines, makes install & removal process easier

Amazing work, Tim! Thanks so much for your time, effort, and attention to detail. And those renders are gorgeous! (Izan and Casper!)

Been watching all your long form videos over the years. Brilliant effort, exceptional content, always. Thanks to all the contextual knowledge I've gained from all those videos over time, this engine comparison summary was perfectly short and sweet. But having said that, I think you did a brilliant job on making this video quite self contained, so it should appeal to both new and old audiences alike. Keep it up!

Hi Tim, great video as always! Can you do a video explaining the navigation techniques and technologies for the landing of both stages

It's so refreshing to find someone who uses proper terms like "center of mass" instead of "center of gravity" and "meters" instead of "elbows"

Still hard to believe this is actually happening 😁

Great explanation of Gravity Drag and why Thrust to Weight Ratio is so important Tim! I was waiting for you to bust out an "area under the force time curve" but you actually explained it super well without going even that far 😃

Thank you so much for the work you put into these videos , the interviews and the research you put in is astonishing.

Sensational video, and very easy to understand. A nice balance with the longer form as well. Well done!
