"Our team looked at specific regions on Mars -- areas where liquid water temperature and accessibility limits could possibly allow known terrestrial organisms to replicate -- to understand if they could be habitable," said SwRI's Dr. Alejandro Soto, a senior research scientist and co-author of the study. Wallace did months of research, consulted various experts, and produced his own scientific analysis of the Martian climate and atmospheric conditions. The bounds of the CHZ are based on Earth's position in the Solar System and the amount of radiant energy it receives from the Sun. “Unlike the previous ideas to make Mars habitable, this is something that can be developed and tested systematically with materials and technology we already have.” “Mars is the most habitable planet in our Solar System besides Earth,” said Laura Kerber, Research Scientist at NASA’s Jet Propulsion Laboratory. Mars is habitable. In astronomy and astrobiology, the circumstellar habitable zone (CHZ), or simply the habitable zone, is the range of orbits around a star within which a planetary surface can support liquid water given sufficient atmospheric pressure. The Mars Exploration Program is a science-driven program that seeks to understand whether Mars was, is, or can be, a habitable world. By: Alfred Russel Wallace (1823-1913) In 1907 Wallace wrote the short book Is Mars Habitable? Transforming Mars into a life-friendly world doesn't have to be a herculean planet-wide effort.. "Mars is the most habitable planet in our Solar System besides Earth," said Laura Kerber, Research Scientist at NASA's Jet Propulsion Laboratory.

to criticize the claims made by Percival Lowell that there were Martian canals built by intelligent beings.

Terraforming 101: How to Make Mars a Habitable Planet. To find out, we need to understand how geologic, climatic, and other processes have worked to shape Mars and its environment over time, as well as how they interact today.

Home Space Astronomy Brines on Mars not habitable, study says.

In 1965, America's Mariner 4 was the first spacecraft to get a close look at Mars. The original question was : What would have happened if the Mars was a habitable earth-like planet ? To find out, we need to understand how geologic, climatic, and other processes have worked to shape Mars and its environment over time, as well as how they interact today.
Venus may have had a shallow liquid-water ocean and habitable surface temperatures for up to 2 billion years of its early history, according to computer modeling of the planet’s ancient climate by scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York. Today, Earth is the only clearly habitable world in the Solar System. That’s Elon Musk’s philosophy, anyways – and just days ago he revealed new details on his ambitions to colonize the Red Planet, including sending two cargo rockets by 2022 and four rockets (two manned, two cargo) by 2024.
