VoiceForget about that vacation home on Mars, at least for now.
NASA says there isn't enough carbon dioxide on Mars to terraform the planet, according to a study released Monday. But Elon Musk disagrees, saying there's plenty available.

Terraforming is the hypothetical process of changing a planet’s conditions in order to make it habitable for Earth’s plants and animals, including humans. The most promising candidate for terraforming is Mars, according to NASA.
In the past, scientists have theorized that carbon dioxide (CO2) and other greenhouse gases stored in Mars’s rocks and polar ice caps could be released back into the atmosphere to make it thicker, heat the planet and allow liquid water to remain on the surface.But the study, published Monday in the peer-reviewed British journal Nature Astronomy, threw cold water on that idea.
"Our results suggest that there is not enough CO2 remaining on Mars to provide significant greenhouse warming were the gas to be put into the atmosphere," said study lead author Bruce Jakosky of the University of Colorado. "In addition, most of the CO2 gas is not accessible and could not be readily mobilized. As a result, terraforming Mars is not possible using present-day technology."
However, in a tweet, Tesla founder Elon Musk said that "there’s a massive amount of CO2 on Mars adsorbed into soil that’d be released upon heating. With enough energy via artificial or natural (sun) fusion, you can terraform almost any large, rocky body."
