"I was wondering if we have ways of measuring the age of planets. If so, do we know which planets are oldest and which are youngest?"

Lewis Matson said:
Research priorities should include the section: “Question: What procedures should be followed to terra-form Mars?” And the following sub-question: “What are the review requirements and authorizations by Science field for terra-forming? “
Tasks:
1) Identify plants that can be delivered to Mars and expected to grow given the atmosphere and soil.
2) Identify/build/test a system that can be placed nearby which can transmit plant growth status.
3) Identify quickest controllable methods for raising the oxygen level.
4) Design a drill capability to drill for water and return a sample.
