MARTIAN CLIMATE:
A Message from Warmer Times

Matthew P. Golombek

Data from space missions have indicated for some time that Martian climate may in the past have been warmer and wetter than today's desiccating environment. Last year's Pathfinder mission provided data at an unprecedented level of detail, and helps to understand climate change on Mars. Several billion years ago, liquid water must have been abundant on Mars. Since then, slow erosion by wind-driven dust and sand has sculpted surface features in some areas, while dust has been deposited in others.
