Ever since billionaire Elon Musk delivered his speech "Making Humans a Multiplanetary Species," Musk and his commercial space flight company has garnered the interest of many. Some antagonistic in nature, but most are eager to find out more about how mankind will be able to colonize Mars.

In his speech, Musk said that there are very specific tasks to complete before men can finally set foot on the red planet. One important thing is to build a powerful rocket capable of transporting crew to the red planet and second is to create a propellant-mining system on Mars that will try to get useful elements from Martian resources. The next step is to build a sustainable human habitation on Mars, a must for whoever intends to colonize the red planet.

Recently, Musk discussed other integral parts of SpaceX and its mission to Mars and they once again heightened the anticipation of many.  For the benefit of those interested in reaching Mars, Musk revealed some very detailed information during a Reddit AMA session last Sunday, Oct. 23.

Glass domes are more likely to be the core of a Martian community, as revealed by the SpaceX CEO. The domes will be equipped with underground tunnels and passageways to enable easy access to different sections of the innovative Martian habitation system.

The 'geodesic domes' will be made up of carbon fiber materials and glass. "Plus a lot of miner/tunneling droids," Billionaire and SpaceX CEO Elon Musk said in a statement. These domes will, of course, be pressurized to provide oxygen to would-be Martian astronauts and habitats. Musk also added that the glass domes would house both industrial and green living mechanisms on Mars. However, the commercial space flight tycoon admitted that the glass dome project is still in its initial stage and that the colonization of Mars could be fully explored and executed in about 40 to 100 years from now.

There is also the risk of not getting back on Earth, so the first batch of Martian colonizers should be prepared to "die on Mars" and should fully understand that they might be given a "one-way" ticket to the red planet.

Despite Musk's blatant warning, there are still a lot of people who would like to sign up for the first flight to Mars, including environmentalist and top Hollywood actor, Leonardo DiCaprio who recently admitted to President Obama himself that he wanted to go to Mars.
