New Worlds Observer Poster for Astrobiology Conference in Puerto Rico

This poster introduces New Worlds Observer (NWO) in the context of astrobiology. The poster illustrates what NWO will be able to discover in terms of spectral analysis and photometry, and explains the relevance of these findings to the field of astrobiology.

External Occulters for the Direct Study of Exoplanets

This paper was submitted to the ExoPlanet Task Force in April in response to the task force’s call for white papers. This paper summarizes an affordable, technically-ready, observational approach to finding and characterizing habitable, terrestrial extrasolar planets based on a recent breakthrough in the diffraction control of starshades. The paper illustrates the efficiency with which spectroscopy, photometry, and polarimetry can be performed due to the unique design of the New Worlds starshade. The paper explains configuration, science goals, operations concept, requirements and capabilities, technical readiness, and programmatics and cost for the New Worlds Observer mission.

Powerpoint presented to Goddard Space Flight Center

This presentation emphasizes the importance direct detection and imaging of extrasolar planets can have on astrophysics. The presentation contrasts the abilities of New Worlds Observer with those of Terrestrial Planet Finder and Darwin. External occulters are described and diagrammed to illustrate New Worlds’ operations concept. The fifteen middle slides illustrate the solution to the diffraction problem solved by Dr. Webster Cash. The starshade is shaped through binary apodization which limits the diffraction of starlight around the edges of the occulter. The presentation depicts simulated images of solar systems, possible with New Worlds technology. Included in the presentation are tolerance analysis, deployment sequences and orbit positions. The last six slides conclude with the concept for New Worlds Imager, the concept for a mission to directly image terrestrial extrasolar planets.
