I did aerospace engineering and back in 1987 we had an alum from NASA who did a guest lecture on Friday. He'd just completed a preliminary study into terraforming Mars and the answer was forget it. Here's a slightly longer explanation. Sorry for the math. What this NASA guy introduced us to was what I now call "Planetary Mechanics" which is how much stuff do you need. The sister to that is "Planetary Dynamics" which is how do you make stuff like water cycles and gas cycles and ocean currents work. So how much Earth normal air would you need? Sorry for the math. Mars has a surface area of 144,370,000 km² If you just wanted a 1 km thick layer of Earth standard air on an object that big its easy to approximate it as enough big cubes of air to cover and that's easy because you just change area to volume and you have 144,370,000 km³ of air. Earth standard air weighs 1.2kg/m³. To work out what that 144,370,000 km³ weighs in metric tons you add 9 zeros to convert m³ to km³ and then take off 3 zeros to convert kilograms to tons. Yes this is why engineers like metric. Finally you multiply by 1.2 because its 1.2 kg/m³ And then you get 173,244,000,000,000 tons of Earth standard air. Yes that's a bit over 173 TRILLION tons of air. The simple question is where are you going to find that much air. That's before you ask anything like how are you going to get it there or keep it attached tot he planet because Mars has only 1/3rd of Earths gravity and n magnetic field to stop the solar wind stripping it away. There was this one bright spark who recently told me we'd only need the Oxygen (as in 1/5th) 🤔🤔 So I asked him where he thought he could get 34.6 TRILLION tons of Oxygen? Now I will grant its not technically impossible, but unless you really do have God like powers, it is like trying to build a 1 to 1 scale model of Mount Everest out of Lego.

@justatiger6268 Actually as an aerospace engineer I'd go in a heart beat. BUT we just don't have the technology to do it and we aren't even close. In the simplest the Space Shuttle was an amazing technical achievement and the ISS is a necessary step for more manned missions beyond Earth BUT both were poorly mismanaged and that's cost years in terms of people working on what we needed and the money cost has been staggering. That's why we haven't been back to the moon. Too much money was spent on the Space Shuttle and that snowballed into the cost of the ISS and in doing that people weren't developing the next generation of technologies.

@justatiger6268 And so we are sure any mission I'd take to Mars is a RETURN trip not a 1 way. Definitely NOT a 1 way.
