AEROSPACE ENGINEER HERE: I did my degree in the late 80s and during my senior year we had an alum who gave a special guest lecture on Terraforming Mars. We were all very excited to hear what he had to say. He started with "Sorry its impossible and here's why!" He then went on to explain just how big planets are and how much stuff you need to a job like Terraform Mars. The numbers are so large that its near impossible for people to grasp. Here's 1 simple thing maybe people can grasp. Imagine a dome (1/2 sphere) on Mars with a volume of 1km. Its about 1562 meters in diameter. So its not a small dome but is the sort of size you'd need for a colony its people, plants and animals. Other than all the materials needed to build that dome (which is substantial). You need 1.3 million tons of air to fill it. Most people don't think of air as weighing much. 1 cubic meter of water weighs a metric ton. 1 cubic meter of air weighs 1.3kg (sea level). There's 1,000,000,000 (billion) cubic meters in a cubic kilometer. So 1 cubic kilometer of air weighs 1.3 billion kilograms or 1.3 million tons. Now considering there's almost NO atmosphere at all on Mars let alone much Oxygen or Nitrogen to make Earth standard air from you have to ask: For the Mars startup colony where are they going to get 1.3 million tons of air from and how are they going to get it to Mars or produce it on Mars? Sorry to bust everyone's Elon Fantasy with math but then WTF I'm an engineer!

Depends which club? If its the American Chapter of NOBFAC (No Brain Function Allowed Club) then I think Dave is right at home in their club.

@LP-ct9nk NO and even if it was he'd probably ignore it.

@douglemay7989 Absolutely and I think we could actually do a "go fund me" to get him there.
