About 4.5 billion years ago a supernova exploded, causing a nearby interstellar cloud to collapse - creating our solar system. What emerged first was our sun, blowing the lighter gases outward. This allowed the heavier elements to remain in the inner solar system, forming our terrestrial planets. We are lucky to have Venus and Mars, two terrestrial planets that are very similar to the Earth and with significant atmospheres. Planetary scientists have developed the capability to model how these planets have evolved since their birth and what may happen to them in the distant future. Comparative planetology tells us that terrestrial planetary atmospheres have been in a process of continual change. We are finding some startling parallels that suggest both Venus and Mars had environments that would have been habitable for life in their distant past. In the outer part of our solar system, Europa and Enceladus are thought to have an ocean of liquid water beneath their icy crust in contact with mineral-rich rock. These icy moons may have the three ingredients needed for life as we know it: liquid water, essential chemical elements for biological processes, and sources of energy that could be used by living things. With these discoveries in mind, we are looking for potentially habitable exoplanets and have made some significant discoveries. Some of these exoplanets must be ocean worlds!
Dr. James L. Green received his Ph. D. in 1979 and began working at NASA, where he developed and managed NASA's first internet. Several missions have been successfully executed under his leadership at the Planetary Science Division, including spacecraft to the moon, the Pluto flyby, and the landing of the Curiosity rover on Mars. Jim has received numerous awards, has written over 115 scientific articles about Earth and planetary science, and over 50 technical articles on data systems and networks. In 2015 Jim was part of NASA's involvement in the film ”The Martian.” He was appointed Chief Scientist of NASA in 2018.

You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
