Why astrobiologists should NOT get rid of the term ‘life’

Carol Cleland rebuts Spacek's argument about uselessness of the term 'life' to astrobiologists. According to her 'life' is useful despite our inability to define it.

Cleland & Grinspoon response to Benner: Do synthetic microbes provide another example of life?

The NfoLD's White Paper on Standards of Evidence in Life Detection opened a discussion on this blog. In this piece Carol Cleland and David Grinspoon tear down Benner's "second example" of life.

But We Have More Than One Example …

Carol despairs of having truly agnostic biosignatures to detect alien life, as it is impossible to extrapolate from the one example of life that we know. But that is the gift of synthetic biology, inductive logic, and reductionism. We induce agnostic biosignatures by understanding the chemistry required for biology.

The Problem with Agnostic Biosignatures

Agnostic criteria, which are currently very popular among NASA scientists, are not truly agnostic and share many of the same problems with a definitional approach for searching for unfamiliar forms of life.

Grave Expectations

The problem with trying to codify an official protocol for recognizing biosignatures: We can try to devise rules for how detecting alien life should unfold, but E.T. might not play along.

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?

Is NASA making itself irrelevant to the search for life in the cosmos?

NASA holds this week a workshop to consider looking (again) for existing life on Mars … but only 20 years from now. By then, humans may have been on Mars for a decade, thanks to Elon Musk, or (maybe) someone less interested in planetary protection. Thus, in 2042, detecting indigenous Martian life will likely be much more difficult. NASA will be too late.
