Mars Colonization News and Updates

The Space Race is dedicated to the exploration of outer space and humans' mission to explore the universe. We’ll provide news and updates from everything in space, including the SpaceX and NASA mission to colonize Mars and the Moon. We’ll focus on news and updates from SpaceX, NASA, Starlink, Blue Origin, The James Webb Space Telescope and more. If you’re interested in space exploration, Mars colonization, and everything to do with space travel and the space race... you’ve come to the right channel! We love space and hope to inspire others to learn more!

0:00 Introduction
1:25 The Alpha Centauri system
3:44 Proxima Centauri B
7:20 Let's colonize Proxima Centauri B
8:55 How do we get there though?

[TheSpaceRaceYT]

Correction, we said Proxima B is 7.5 km away from its Sun but we meant 7.5 million km.

Isaac Arthur also had a really great video on colonizing alpha Centauri. He believes though that we could get there in our lifetime if we extend the average human lifetime, which he believes will progress quickly enough to be feasible. So get a fusion drive and a big comfortable city colony ship and wait out a few hundred years to get there!

5:09 Proxima Centauri is a low mass star that will not go supernova !

Channel is a hidden gem, hopefully not for long.
Space Race really stands out in candidness, accuracy and the insightful but unbiased content being produced so consistently for such a small channel.
Make sure we all share with our friends y’all.

The errors... 7.5km orbital distance, huh? And claiming that a red star is safer because it won't go supernova in xxx trillion years. Well, newsflash: It's a red dwarf, it's _never_ going to go supernova. It's too small for that. On the other hand, red dwarf stars are anything but safe to be around, they're well know for their *massive* flares that'll easily wipe any planet in its "habitable zone" clean of anything resembling life on the regular.

4:19 it should be 7.5 million KM, not 7.5 KM.

Great video. I do enjoy how tight the script is, plenty of facts without any fluff.

I really enjoy the concept of 'solar' highways around the solar system and to other stars. Fell in love with the idea when I first heard about them from Isaac Arthur's discussion on the topic.

Just for inner system time frames could get cut down to something actually useful.

Fingers crossed for more video's around getting 'around' our solar neighborhood!!

The idea of escaping an extinction level event by running to another star system with all the same potential, or greater, to kill us as that of the good ol’ Solar System, just leaves me scratching my head. Much, much simpler to build habitats (think O’Neill Cylinders built to live in interstellar space) and avoid all the dangers of living at the bottom of a gravity well that regularly blows up, all while orbiting a monstrous and wide-open fusion furnace, is just nuts. Building O’Neill Cylinders is certainty challenging but not nearly as challenging as moving an equally large percentage of humanity to another star. Come on, Man

[flippdoubt]

7.5 kilometers???! Is that true? Your presentation is amazing as always; I love your channel! Keep up this continued content & you’ll keep growing for sure!

[christaran]

I thought only our star system was the solar system due to our sun being named Sol.

[xiphactinusaudax]

We should definitely send a space telescope over there, one that goes extra-extra fast to beam back information. It would be cool to see information back. In a few years of course, we don't possess the tech right now, but it's within our grasp, and I want to actually look at interstellar photos in my lifetime

[orion]

This video is priceless. @7:15 I learned I can run from B to its star in 50 minutes.

[erideimos]

Wow, your best episode yet and they've been great so far already! You really researched the best thinking on the concepts and threw in a ton. Thanks!

You are so absolutely right that you build space infrastructure before setting up camp on the planet surface. The first things an incoming colony fleet will want is energy (fissiles, solar and fusion fuel) and resources (volatiles and non-volatiles like metals and carbon, etc.). The best place to get matter is floating rocks of all sorts as you say. So I think the first three spots will produce energy, volatiles and non-volatiles, working together for manufacturing. Then comes the orbital infrastructure (power, geo and com satcons and stations). Then comes sort some of orbit-surface transportation system, where you hit the nail on the head again. Orbital rings or launch loops/drivers would be incredibly big megaprojects for a new colony. But your orbital mirror idea to simulate Earth days on the darkside is great and really thought out imo.

10:40 Billionaire Zuckerberg has been partners with a Russian billionaire oligarch for years working on a huge project that involves putting the largest laser in history in a huge facility on the Moon? If that's just the cover story, I wonder what their billions have really built so far, and where. What kind of shit needs that kind of cover story? Could be an episode ;)

Anti-matter is a bit down the road. Not only producing it in quantity, but storage seems impossible on a ship, let alone a little one. Perhaps if we build a century ship with 100, 000 people, anti-matter propulsion, power and storage will make sense and be possible.

4:18 *"Proxima b is only 7.5 kilometers away from its star."* Let that sink in. You look up, and the entire sky is filled with the blazing sun just a few blocks away. And the gravitic tides! Proxima b would have to be ultra dense of course and moving at relativistic speeds, which make landing tricky. [It's 7.5 *million* km :) ] And good news, 5:10, it will never go supernova, or even nova, because it is much too small. Not even if all three kicked off together would we get a supernova. Just keeping ya honest :)

Thanks again, outstanding!

[leenorman]

All these planets are tidal locked. Great idea and amazing video but unfortunately we need to keep looking. Can't wait to see the next vid

[moruompusang]

We could just turn the moon into a spaceship and survive through space until we find another planet to become aliens to .

[willCollett]

We should definately find a way of the Earth. All this talk about colonizing Alpha Centauri is like humans looking at the moon in the 18th century. All the complications in getting to the Moon and there is almost NO idea of what is in the Centauri system. Reallity can be very painful. Nice video.Our science is still young.

[kennarajora]

8:55 I noticed you didn't mention Nuclear Propulsion as a method of transit. Look at projects like Orion and Nerva. Scientists who worked on Orion believed that they could use Nuclear Propulsion to accelerate a Spacecraft to 3.3% the speed of light, and that this ship could theoretically reach Proxima Centauri in as little as 133 years (keep in mind, this calculation was made using 1960s technology, when the project was first proposed). The method has a number of benefits over both antimatter drives and solar sails: 1. unlike antimatter drives, we have the technology to produce the amount of fuel needed for the journey 2. unlike solar sails, we can easily scale up the project to carry people, and 3. we have a method of slowing down once reaching our target, solar sails don't.

[colinhouseworth]

If we have the energy tech to get to Proxima we will be way past needing solar panels to set up shop once we’re there. Likely either fission or fusion energy.

[colinhouseworth]

Antimatter engines are not warp drives. Man you really dropped the ball on this video. Third mistake I’ve caught so far.

[Michaelca]

5:09 Proxima Centauri is too small to go supernova. It will end as a white then black dwarf.
