The Mars Daily Editorial Team produces Mars Daily's coverage of Mars exploration and science. We report on rovers and orbiters, sample-return and human-Mars planning, and the geology, atmosphere and astrobiology of the Red Planet. Articles reflect our team's collective editorial process, source verification, drafting, technical review, and editing, rather than a single writer's work.
