Previous missions to Mars have investigated the surface history of the Red Planet by examining features like canyons, volcanoes, rocks and soil. However, signatures of the planet's formation can only be found by sensing and studying its "vital signs" far below the surface. In comparison to the other terrestrial planets, Mars is neither too big nor too small. This means that it preserves the record of its formation and can give us insight into how the terrestrial planets formed. It is the perfect laboratory from which to study the formation and evolution of rocky planets. Scientists know that Mars has low levels of geological activity. But a lander like InSight can also reveal just how active Mars really is. more »

The continued warming that is projected to occur without substantial and sustained reductions in global greenhouse gas emissions is expected to cause substantial net damage to the U.S. economy throughout this century, especially in the absence of increased adaptation efforts. With continued growth in emissions at historic rates, annual losses in some economic sectors are projected to reach hundreds of billions of dollars by the end of the century — more than the current gross domestic product (GDP) of many U.S. states. more »

"I know," I said, falling easily into our mother/teacher, daughter/pupil mode. "A dell is a small valley or hollow, usually secluded." I find myself wondering how long it will take people to realize that when we take out trees, we take out the oxygen producers that keep us alive. Humans inhale oxygen and exhale carbon dioxide. Trees inhale carbon dioxide and exhale oxygen. It's that simple. more »
