2004 Annual Science Report
Virtual Planetary Laboratory (JPL/CalTech) Reporting | JUL 2003 – JUN 2004
Executive Summary
THE VIRTUAL PLANETARY LABORATORY
Laying the Scientific Foundation for the Search for Life Beyond the Solar System
Because of the vast distances to even the nearest stars, the search for life outside our solar system will be undertaken using astronomical, or “remote-sensing” techniques. While much can be learned about a planet discovered around another star based on the characteristics of the host star and the planet’s position in its solar system, spectroscopy is still our most powerful technique for extrasolar planet characterization. The research of the NASA Astrobiology Institute’s Virtual Planetary Laboratory (VPL) uses computer models of terrestrial planets to understand the nature and potential range of remote-sensing spectroscopic signs of planetary habitability and life which might be encountered by future planet detection and characterization missions.
Terrestrial Planet Detection and Characterization Missions
There are several missions currently in the planning stage to search for and ...

Characterization of Terrestrial Planets From Disk-Averaged Spectra: Spatially and Spectrally Resolved Planetary Models
his task uses sophisticated spatially and spectrally-resolved radiative transfer models and data from planets in our own Solar System to explore the detectability of surface and atmospheric properties of terrestrial planets from disk-averaged spectra at a number of different spectral resolutions

Spectroscopic Databases to Support Extrasolar Planet Modeling
To support efforts to understand the nature and detectability of terrestrial planet characteristics for planets around stars of different spectral type, this task focuses on collecting and preparing full wavelength, continuous stellar spectra for use by the planetary climate and chemistry models (c. f. Task 6).
