    • Historical Perspectives: Evolution of Recent Mars EDL Systems Development 

      Hines, Erisa K. (Georgia Institute of Technology, 2008-06-24)
      NASA's history of Entry, Descent, and Landing (EDL) -dependent missions has its share of success stories and failures, often both present in any given mission. This paper focuses on the success and failure stories as they ...
    • Instrument Accommodation on the Pioneer Venus and Galileo Probes 

      Bienstock, Bernard J. (Georgia Institute of Technology, 2008-06-24)
      Probe missions afford participating scientists the opportunity to perform in-situ measurements of atmospheric properties as well as planetary and satellite imaging. Extreme environments, limited volumes, modest levels of ...
    • Key Features of the Entry, Descent, and Landing Repository 

      Martinez, Elmain (Georgia Institute of Technology, 2008-06-24)
      This poster will illustrate the key features of the Entry, Descent, and Landing Repository (EDL-R) web application. Features of keen interest, such as security, multiple search methods, the submission process, and automatic ...
    • Mass Advantage of Titan Aerocapture 

      Strange, Nathan; Bairstow, Sarah; Spilker, Thomas (Georgia Institute of Technology, 2008-06-24)
      NASA's 2007 Titan Explorer study employed Titan aerocapture to place a spacecraft in orbit around Titan, while NASA's 2008 Titan / Saturn System Mission (TSSM) study enters Titan orbit propulsively. These two studies may ...
    • Overview of Flagship Class Venus Mission Architectures
