There's a lot to figure out yet.

 

So far, I've only had the chance to listen to the first 11 minutes of this interview with astronaut Chris Hadfield but man is it interesting.

 


Hey there goes Alex. He's loaded with money. Wow he's really set himself up great.

The first thing I did was to have a look at the comments. Really depresses me to see how many angry little ignorant people there are out there.

Mars is so last week.

I'm holding out for Titan.

Dude, where's my parka? Third line.

I didn't get past a load of 9/11 conspiracy stuff.

 

Surely we should be trying to establish a Moonbase before getting to Mars?

 

This idea is important in the (really) long run as global warming will eventually make Earth unihabitable.  I don't mean CO2 from our engines, I mean the sun getting hotter.  There is evidence that current Hell-world Venus was once inhabitable, and Earth will go the same way.  Maybe our far descendants can planet-hop out to Mars, then the moons of Jupiter, maybe even Pluto.  Of course that's the end of the line unless we invent warp drive.

Or generational ships.

Getting to Mars is highly problematic. How do we protect the human cargo from cosmic rays?  Even a pea-sized meteor strike could wreck the ship.

Yes, you're right. That alone is a huge technical challenge. Until we invite the star trek deflector array.. To push stuff out of the way.

Explorers of old faced similar challenges sailing across Atlantic and Pacific.

Not manned. But if successful, it would be impressive.

Most impressive.

Not manned but they are addressing the supply issue with this flight.

Great point.

Plus, what they learn from capsule behavior, etc, will feed into a manned project most likely.

Awesome stuff.

But wouldn't recommend transporting astronauts beyond Earth-moon region. Wouldn't be fun for longer journeys. Internal volume ~size of SUV. 9:45 AM - 27 Apr 2016
