  • Hey There! Welcome to Life Noggin!

  • It seems like everyone wants to go to Mars nowadays.

  • The red planet has been all the buzz with organizations like NASA and SpaceX promising

  • to get us there in the next ten-ish years, but there are so many problems with living

  • on Mars.

  • Instead, some experts think we'd be better off heading for the scorching, toxic land

  • known as Venus!

  • Yes, really.

  • People have been talking about going to Mars since the 1950s and we obviously haven't

  • made it yet.

  • Many of the problems with this idea revolve around money and technology, but there's

  • more.

  • Since Mars has less than half the gravity than we have on Earth, we'd need to figure

  • out how to combat physical issues like muscle degeneration and vision problems.

  • And spacecrafts would need to be able to land safely on a planet with hardly any atmosphere

  • to slow them down.

  • Powerful solar storms bombard the surface with crazy high levels of radiation.

  • And it's freezing there, with temperatures dropping to almost negative 125 celsius.

  • Humans would need some serious protection if they really wanted to live on Mars.

  • We may need another option.

  • Venus.

  • You may be saying, “Blocko, Venus is like 425 degrees and the air is poisonous.

  • Plus, the atmospheric pressure would crush us!”

  • And you're correct!

  • You're so smart, but people have some pretty viable ideas for space colonies in Venus's

  • neck of the woods.

  • About 50 km above Venus's surface, there's an airspace with similar gravity, pressure,

  • and solar radiation protection to what we have here on Earth.

  • The temperature ranges from about 30-50C, creating a fairly livable atmosphere.

  • This all sounds pretty promising and NASA thinks so too.

  • In 2015, NASA announced their High Altitude Venus Operational Concept, aka HAVOC... which

  • I feel like isn't the most optimistic name for a space mission.

  • This project would send two astronauts to Venus's upper atmosphere, hovering in spaceships

  • above the clouds.

  • This initial trip would last 30 days and could lead to future colonization of Venus's airspace.

  • Floating cities!

  • How cool would that be?!

  • Humans wouldn't even need pressurized suits or radiation shields to go outside!

  • Sure, they'd still need oxygen and something to protect them against Venus's sulfuric

  • acid rain, but no more bulky astronauts suits?

  • Sounds good to me!

  • And the carbon, hydrogen, oxygen, nitrogen and sulfur in Venus's atmosphere could be

  • used to create breathable air, fertilizers for crops, and even water!

  • You may be wondering how these floating cities would be powered.

  • NASA has given some clues as to how this could work (and we've got some ideas too).

  • Firstly, the vehicles would be equipped with massive solar panels to take advantage of

  • the sun's energy.

  • Second, there's the possibility of using the carbon in the atmosphere to generate electricity

  • via graphene-powered superconductors or synthetic photosynthesis.

  • People living in these floating cities could also eventually begin to terraform and colonize

  • the surface of Venus with the right technology, but that'd take a while.

  • Some have proposed flooding the lower atmosphere with hydrogen to create an ocean that'd

  • cover 80% of the planet.

  • Others suggest striking the planet with large objects to speed up it's rotation, hopefully

  • warming the planet and changing its atmosphere.

  • These plans would be really difficult but personally, I think living in a floating city

  • sounds cooler anyway.

  • So what planet should we explore next?

  • Let us know in the comment section below!

  • Living on Mars or Venus seems like a cool idea, but if you're curious about how you

  • could live on a moon without a spacesuit, check out this video from our friends Seeker.

  • Saturn has 62 confirmed moons with more being discovered all the time, and 2 of these moons,

  • Titan and Enceladus could be habitable.

  • As always, MY NAME IS BLOCKO!

  • This has been Life Noggin.

  • Don't forget to keep on thinking!
