Mars Could have Enough Molecular Oxygen to Support Life

Could Some Craters on Mars Have Acid Water Origins?

Introduction: Physical sedimentology experiments using a 39% concentration of sulfuric acid have produced three distinct features, which are similar to features seen on Mars. However, these sedimen-tary features could not be created using pure water in the laboratory. These three features include deeply-incised, narrow channels, cracks that run parallel to the flow direction, and circular depre...

I have had enough!

I apologize for making some of you nervous, and perhaps even resentful, but I HAVE HAD ENOUGH! I do not like the new unethical face of my profession, where incessant seeking of more money has replaced service to the public, honesty, and self-respect. Numerous areas of major ethical concern in dentistry are identified in this article. The ongoing, if not accelerating, degeneration of professiona...

Sustainable life support on Mars – the potential roles of cyanobacteria

Even though technological advances could allow humans to reach Mars in the coming decades, launch costs prohibit the establishment of permanent manned outposts for which most consumables would be sent from Earth. This issue can be addressed by in situ resource utilization: producing part or all of these consumables on Mars, from local resources. Biological components are needed, among other rea...

In-situ resource utilization technologies for Mars life support systems.

The atmosphere of Mars has many of the ingredients that can be used to support human exploration missions. It can be "mined" and processed to produce oxygen, buffer gas, and water, resulting in significant savings on mission costs. The use of local materials, called ISRU (for in-situ resource utilization), is clearly an essential strategy for a long-term human presence on Mars from the standpoi...
