what they are but it's also a reminder that clear goals timelines and targets aren't necessary to remain the leader in the space industry last week's comments in the thread were great again mick glow here thinks that the holy grail of space flight would be a single staged fusion power spacecraft and yes perhaps musk should call it the holy crawl of space flight with current technology perhaps it isn't as catchy that way fusion power in the future of course if harnessed well would in reality be quite insane compared to chemical rockets and could provide extremely efficient and a lengthy burns to accelerate at a phenomenal speed because of that efficiency it wouldn't need the massive fuel supply either a direct fusion drive has been estimated to have a specific impulse up around NUMBER_TOKEN NUMBER_TOKEN seconds or so compared to say a vacuum raptor at NUMBER_TOKEN seconds that would make an extraordinary difference at the same time the fusion reactor can also provide vast amounts of power to use for the ship itself sadly though we seem to be eternally NUMBER_TOKEN years away from being able to create fusion power with massive reactors here on earth imagine the possibilities though if one day we can nail it bill here making the great point that no launch vehicle is a sure thing reiterating the point that we were making last week starship has many challenges to overcome it's going to be quite some time to become profitable even if everything does go to plan so yes totally agree there bill but i'm also looking forward to watching this adventure play out i'm confident that if any company can do it it will be spacex remember the ore that we all felt watching these starship test flights earlier this year they felt like a huge step towards the goal but we're still a very long way off the orbital flight tests and re-entry tests coming with a new heat shield are big challenges alone even if spacex could not achieve all goals they will still though be left with a stunningly cheap and at least partially reusable launch system for super heavy payloads so thanks for coming back to yet another saturday update with me if you are new i hope i earned your subscription today thanks to all of you always here for watching liking and commenting every bit of that interaction helps watch time certainly seems to be the most beneficial so simply letting a video play right through to the end helps us the most i think if you are directly supporting those through patreon or youtube such as all these terrific people listed here that also makes a world of difference and it also lets us work on deeper dive topics from time to time as well that also goes for the many of you picking up some gear from a merch store including this shirt that you see right here like this candle remember that if you like light colors to pick the dark version of the design so that it stands out you certainly don't want the white text on a white shirt and all that sort of thing today in the tile in the bottom left we have my video from last week talking about ula's stp-NUMBER_TOKEN mission and nasa's xp mission launched by spacex's falcon NUMBER_TOKEN. in the top right is my latest video and in the bottom right a video that youtube has suggested especially for you thank you as always for making it all the way through i'll see you all in the next video
START_INTERACTION_TOKEN if you are new i hope i earned your subscription today thanks to all of you always here for watching liking and commenting every bit of that interaction helps watch time certainly seems to be the most beneficial so simply letting a video play right through to the end helps us the most i think END_INTERACTION_TOKEN BETWEEN_SEGMENTS_TOKEN START_SELFPROMO_TOKEN if you are directly supporting those through patreon or youtube such as all these terrific people listed here that also makes a world of difference and it also lets us work on deeper dive topics from time to time as well that also goes for the many of you picking up some gear from a merch store including this shirt that you see right here like this candle remember that if you like light colors to pick the dark version of the design so that it stands out you certainly don't want the white text on a white shirt and all that sort of thing today in the tile in the bottom left we have my video from last week talking about ula's stp-NUMBER_TOKEN mission and nasa's xp mission launched by spacex's falcon NUMBER_TOKEN. in the top right is my latest video and in the bottom right a video that youtube has suggested especially for you thank you as always for making it all the way through i'll END_SELFPROMO_TOKEN
