I love Robert's passion. I am glad he will see it happen. NASA awarding Spacex the contract will hasten the development of the Star Ship and make Mars possible this decade
I’m surprised that as we’re getting closer to being able to go to Mars, there’s so little interest in the Mars Society. I don’t think NASA is going to train astronauts to survive on Mars, so that will probably have to be done by people like the Mars Society.
Human built settlements and locations on the Moon and Mars will be named after this guy. "Hey man I hear you're from Mars"? Yea, grew up in Zubrin City
Gotta push back on Zubrin's statement that methane is the easiest propellant to make on Mars. In order to make methane you have to mine ice which can be made into the more efficient hydrolox that would work better in Mar's thin atmosphere. Methalox is better for Earth's thicker atmosphere but bigger tanks aren't a problem in the thin atm. on Mars. Making methane on Mars adds unnecessary steps to achieve an inferior result.. One vehicle for two very different jobs is suboptimal. There is no need for nuclear power at the poles of the Moon. Two or more interconnected sites in the mountains can provide constant power. One peak has sunlight 93% of the time. For Mars solar power satellites beaming power to rectennas on the surface can provide power, positioning and comm for the whole planet. Kilopower reactor weighs 150 kg/KW while solar in orbit using low mass mirrors would be less than 5 kg/KW add another couple kg's for antenna and electronics and it puts maybe 20 times the power/mass. In addition three times as much mass per IMLEO can be placed in Mars orbit vs. the surface.
47:20 I thought that martian conditions were so unfavorable to rotor flight that keeping incredibly light construction was basically required? Or do you just need your rotors at a sharp enough angle and spinning fast, and that's enough?
Part of why Ingenuity had to be light was because the booster that sent Perseverance & ingenuity to Mars was pretty close to its limits. A few more Kg, & the package might not have made it to Mars. The rest has to do with flying in air that’s a lot thinner than any other helicopter has ever flown in while using only solar & battery power. The large (1 meter diameter) rotors have to spin very quickly to get it & keep it airborne.
High energy cost and battery weight cost & a low payload. Possible but viability is questionable at best. Much more economical on resources and energy to only participate in flight on a as needed occurrence like light weight robots recon. If it died and you were on one your terminal vel would kill you more times than on earth. The hole place is like a hyperloop, near vacuum. Just use tracks way faster more efficient. Rail guns with proximity landing for delivery of materials.
@@TraditionalAnglican I don’t think that’s true about the rocket. The Atlas V that launched Perseverance was the 541 configuration, which isn’t their most powerful. They still had one more solid rocket booster they could have attached, so they had plenty of margin if they needed it. On the other hand, I seem to recall reading/hearing something about Perseverance’s entry and landing system being at its limits, which makes sense. This rover was already heavier than Curiosity. Mars’ atmosphere is super thin and parachutes don’t scale well. I’m not sure how much bigger they could have made it. I think the EDL package was the bottleneck, not the rocket.
@@regolith1350 - You caught me - I had been spending a lot of time talking about InSight, which has been hampered the lack of an RTG & a non-functional drill which had been chosen (instead of a proper drill) because of weight requirements imposed by the Atlas V 401 launch vehicle. Congress had insisted InSight launch on an Atlas V. The least expensive Atlas V was the 401. Launch mass for InSight was 694 kg - Launch Mass for Perseverance & Ingenuity was a total of 3,649 kg (all up including propellant for course corrections & reentry vehicle) which was 14% heavier than Curiosity.

Before they think about putting humans on mars to colonize it they need to sort out the aches of land on mars and the moon owned by people and celebrities first
What's the point in going to Mars??? The gravity is only 38% of Earth. So that means humans can never live their for long periods. It's useless really.
Skip to 26 00 for dr. Zubrin
Thanks
Thank you (n/w coastal California) so much! I'm receiving you, recorded on UA-cam (no computer; just internet & screen). Let's Go!
240 starship launches a year *drooling* Thanks Dr. Zubrin and all of the mars society for a great way to start a morning.
I love Robert's passion. I am glad he will see it happen. NASA awarding Spacex the contract will hasten the development of the Star Ship and make Mars possible this decade
Very well said Dr Zubrin ... about The Martian Movie.... it is YET to come~
Great work Robert! Keep it up guys

I predict it will be named after the Indian company Tata in my book, because the future is unpredictable.
@@daviddean707 Many settlements and locations will need a name...

It's good idea to start compaby and develop and produce whatever will be needed on Mars for colony.
Brilliant
Two years in and I'm only the 214th like!! What the hell, humans?!

Next meeting, I move to ban the most frequently used word in the video . . um
"Okay" ;-)
um.....
