Welcome back my friends to an intriguing week. We have so many great things to finally dive deeper into around Starbase and Starship updates as they prepare for flight 4. Many have been asking about the 40-50 tonnes to orbit for the current Starship design which came as a surprise to all of us (including me) from Elon's presentation last week. What are the SpaceX Starship Expectations vs. Reality? Is There a Problem? Raptor is the key, and it is complicated. Do we also have a dry mass problem? Are they runni...

    I had seen something that implied that the tanks were not quite full for flight 3. That might end up with engines running at 90% or less and fly the desired profile with no need to dump fuel at the end.

    Marcus this is a great report. Unfortunately, the use of the word 'ludicrous' in your banner is misused far too frequently. I am sure you did not mean that the Starship modifications are ' unreasonable; cannot be taken seriously, or absurd, or ridiculous'. Yes, these accomplishments are 'amazing, marvelous and outstanding'.

    a Mars cyler is a waste of effort - to use it you have to match its orbit - in which case you are already on the way to Mars. you need the Same amount of fuel (actually more for extra maneuvers. Thus no gain. and a significant waste for the cycler itself as you have to match its orbits just to resupply it.

    I used to be subscribed to Felix's channel, but I cancelled my subscription because his presentation style can be a little off-putting for me at times. I much prefer Marcus's style and there seems to be fewer promotions, although I haven't timed them with a stopwatch or anything. I guess Felix can be irritating sometimes whereas Marcus is never irritating.

  • @mikemccormick6128

    NASA going to Mars during the 2030s has already officially been updated to the 2040s. That is not in any way surprising due to the fact that they are completely relying on Congress for funding. They don't even have a vehicle capable of going to Mars anyway. They do have a Mars capable rocket, but Orion is only practical for going to the Moon due to the small size. Elon is even worse at predicting because originally he said SpaceX would be going to Mars in 2022 and the first astronauts would launch in 2024. But I do believe SpaceX will beat NASA to Mars because they already have both the rocket and spaceship. NASA will have to go through the process of selecting a bid winner to construct a Mars capable spacecraft. Even if NASA chooses SpaceX and Starship as a partner, I would see that as SpaceX going to Mars and not really NASA going to Mars because the only thing NASA would be contributing would be logistics. Even if NASA provides funding to SpaceX, I feel like that is irrelevant because SpaceX is going to Mars whether or not they get funding. The main reason that Starlink got started in the first place was to provide Mars funding.

    • @MarcusHouse

      Indeed Mike. Any space endeavour seems to involve extremely lengthy delays. Even SpaceX have made poor decisions that have slowed them right down such as lack of an initial exhaust mitigation. Every step they improve though, so I do still think SpaceX will get there in the end. Lots of hurdles to jump before a moon landing yet though. For now I just want to see mass to orbit with full reuse. After that, the game has changed even if they need a totally different design for the moon and Mars.

We only used to need „Anti-Virus“… - now we expect our OS to come with an inbuilt solution, but now we have three other problems we didn’t have before… Edit: forgot the VPN‘s we need to get beyond the geographical market restrictions the media companies placed on us… (To be honest VPNs are probably legal loopholes, so the security services get the data of the local population without breaking the law (that in some countries forbids spying on your own people), because the data is now seemingly via a different country.)

    This is hilarious - I’m a space fan in general, and will always appreciate the incredible things NASA has accomplished. For the last decade, everyone has completely $hit on NASA as some useless government entity that’s building a rocket half as capable as starship. Remember when we were placing bets on which would launch first? Just launch, not actually do anything. Yeah, SLS was beat as the most powerful rocket in the world shortly after its launch by starship, but uh… now we learn that SLS (as it stands) can deliver TWICE the payload to LEO, and its upper stage will be vastly more capable (unrefueled) for deep space missions?! I understand that Starship will evolve into a complete beast, but currently, it’s now apparent that it’s simply a MASSIVE disservice and distraction to SLS’ capability. I genuinely hope that spacex fanboys can now appreciate the achievement of SLS launching a perfect mission on the first attempt; capable of twice the LEO payload vs. Starship. In the media (and social media) SLS was simply blown away by Starship as soon as it left the pad. We now know this simply isn’t true (and honestly, at face value the numbers never really added up for me - this shouldn’t come as a surprise for many.) So be humble and give credit where it’s due. If SpaceX were to launch a perfect mission on their first attempt with a rocket capable of 95 tons to LEO - EVEN EXPENDABLE, it would likely take them another ~3 years and the total program cost (including infrastructure and R&D) would likely be approaching or exceeding that of SLS. Which is here today. Yea - reusability will eventually turn the tables, but even NASA and their fans always admitted this. Also, this makes the Artemis plan (endlessly debated as being pointless with the Starship capability) look a lot more appealing (using BOTH rockets, on their current schedule.)

      It’s embarrassing that people still believe anything Elon says. The fact is, starship can purportedly take 40-50t to Leo with twice the power of a Saturn V, while the Saturn V could deliver 40t to the lunar surface. For them to claim that ship revisions 2 and 3 will hit their targets is very questionable with the amount of “we hope the engines will be more powerful” and “we hope we can scale this, not operational, system up and it will work perfectly”. I wait to be proven wrong but I’m not holding my breath.

    Hi Marcus - Starship 3 might even be capable of single stage to orbit, provided it only had a tiny payload and the vacuum nozzles were a bit different of course. That’d be quite something and might open up crew to orbit and modest point to point possibilities without having to worry about a booster. What do you think? Have I got this right?

  • @alexandervocelka9125

    Slamming a vehicle into a dense atmosphere is neither sophisticated nor efficient or save. With space refueling we won’t need dangerous and expensive slam braking anymore. The structure of a Starship as it is designed now will not survive a slam braking. Far less does it make sense to slam brake in the hundreds times less dense martian atmosphere or land with a slam safe structure on vacuum bodies like the moon. Safe on mechanical mass and use more fuel is the way to go. Now, we haven’t even spoken about landing on natural ground or even just about taking off from such a ground. All this points to a spherical design with an equatorial ring engine and normal engine landing.

    • @lazarus2691
      @lazarus2691 3 일 전

      Have you never played kerbal space program? Or have any understanding of the tyranny of the rocket equation? Using fuel to slow down is horrendously inefficient. Starship has a mass ratio of about 10. A really, really good upper stage might manage a mass ratio of 30. So we can cut Starship's weight down from ~120 tonnes to ~40 tonnes if we're not trying to make it survive aerobraking. Delta-V needed to reach orbit is about 9km/s, so doing the entire thing backwards entirely under rocket power will take the same. The Raptor engine has an exhaust velocity of 3.6km/s, so the equation is e^(9/3.6)*40 = 487 tonnes total mass, which means 447 tonnes of fuel. Starship cannot get anywhere near that much mass into orbit in the first place, nevermind do so with any payload to spare. Even for Mars, we need to slow down by about 7.5km/s, so e^(7.5/3.6)*40 = 321 tonnes, or 281 tonnes of fuel. So by stripping 80 tonnes of mass from the ship, we now need to carry an additional 281 tonnes to Mars, or about 200 tonnes of extra weight. And by the way, deceleration on Earth takes place at high altitudes, where the atmosphere is just as thin as Mars.
