"This roadmap outlines research pathways to determine whether Mars could be warmed with non-biological methods. It does not presuppose that warming Mars is desirable; its purpose is to identify what would need to be true for Mars to be

The article quotes Prof. Troian as saying, "JPL acted honorably throughout. They did the right thing and filed the right report. That part of the system worked well. ... My complaint is strictly with Caltech." There's tension

Giving Mars an atmosphere that you or I could breathe is science fiction. It would require designer microbes, or enormous energy input. Extending life beyond Earth - establishing a simple biosphere that's mostly plants - is much simpler. It

My basic gripe with Bell-curve arguments against female genius is that at the high end, in the exponential tail, fine-tuning is needed to explain why a non-negligible fraction of professors at MIT (say) are women. Even a small difference in

Geologist here. Earth's thermal evolution is unsolved decades after we figured out the stars. The Sun's temperature adjusts to energy production and loss on a 10^6 yr timescale (scaling as the time for a photon to diffuse from the heart of

I am a postdoc working on planetary habitability. This arxiv paper is a mesh sieve masquerading as a boat. Complexity's rise is a messy business [1]. There's some evidence for steady progress, easy steps [2]. At the other extreme, the machi

Send people when there's a coherent plan for them to do something useful. Not before. (1) Oliver Morton: "The fact that there are plenty of people who might volunteer ... does not mean that it would be right to indulge them. If they live, t

The landing created an extensive debris field [1]. For example, the descent stage energetically disassembled on impact with 100+ kg of unused propellant still on board, as planned [2]. Bits of plastic and metal are strewn across a 30km-long
