Good video with good production value.
I have written a lot on Mars here and while I am not a real researcher, I have used the latest studies to figure out if colonizing Mars is possible. The conclusion is that it's definitely possible and the small details are being worked on. The radiation, the food production, the water production are all problems that have real solutions.
I know it's going to be a monumental task but I also know that doing this will somehow unite us all under a common goal while at the same time propel the private companies into space, where we are lacking funding and research.

This is some of what I wrote:

If you use #steemstem as a tag you might have an even easier time getting those upvotes :P

Cheers and I hope you join us!
