Radiation on Mars is less likely to kill you than sitting on your couch

We have all heard that radiation on the Martian surface is dangerous to humans and that it would limit the extent of life there, both indigenous and transplanted. However, what is rarely mentioned is how dangerous the radiation is exactly. I will attempt to quantify this danger. In short: If you choose to forgo exercise and have a poor diet, you have a higher chance of premature death due to cancer than if you lead an otherwise healthy life but are exposed to Mars-surface radiation levels.

Assembly Theory and Agnostic Life Finding

Agnostic life finders can either look for molecules that are necessary for Darwinian evolution, or molecules that require Darwinian evolution to make. Assembly Theory promises to resurrect the second strategy after years of failure. Can it?

Ribonucleic acid is formed by percolating ribonucleoside triphosphates through basalt glass

This simple reaction is the last step in a modeled "discontinuous" process that moves from sulfite- and borate-stabilized carbohydrates, a post-impact atmosphere, and rock species delivered from basalt glass, all of the way to what might be the process forming what might have been the first genetic molecules on Earth ... and Mars.

NASA Headquarters Misses the Ball. Polyelectrolytes as the Key to Agnostic Life Finding

Synthetic biology, 20 years ago, taught NASA how to search generally, agnostically, and universally for alien life. NASA still does not understand the opportunity

2022 State of NASA Address: Astrobiology at NASA no longer looks for life on Mars

NASA gave up on looking for life on Mars, while planning to irreversibly biologically contaminate its surface. It is now up to private philanthropists to support life searching missions, while Mars is still biologically pristine. We know how to do it.

Science traceability matrices. Organized thinking, or organized biases?

NASA's workshop this week seeks to use STMs to speed the creation of new ideas to guide missions to detect life in the Solar System. But do STMs simply provide a veneer of respectability to old ideas, blocking the emergence of the new?

Benzoic acid on Mars. A 20 year old prediction come true?

Millan et al. just reported the discovery of benzoic acid in the dunes on Mars. Remarkably, benzoic acid was predicted 20 years ago to be on Mars as a product of organics falling to Mars via meteorite. And possibly ... life. Simply by understanding basic organic chemistry.

The Search for Life on Mars Must Start Now

According to planetary protection guidelines, manned Mars missions could be a severe biological hazard. At the same time, Mars will soon be accessible for those who might choose not to follow these guidelines. If we are serious about planetary protection, we must know if life is present on Mars before humans land there.
