    • Penetration of Probes and Natural Cosmic Bodies into Planetary Atmospheres: Mathematical Interpretation of Observational Data 

      Gritsevich, Maria I. (Georgia Institute of Technology, 2008-06-24)
      The approximation of the actual data using theoretical models in general makes it possible to achieve additional estimates, which do not directly follow from the observations. For example, the correct mathematical modeling ...
    • The Phoenix Mars Landing: An Initial Look 

      Cichy, Benjamin D.; Eldred, Daniel B.; Skulsky, Eli D.; Queen, Eric M.; Bailey, Erik S.; Chase, James P.; Prince, Jill L.; Lisano, Michael E.; Grover, Myron R.; Laufer, Paul E.; Desai, Prasun N. (Georgia Institute of Technology, 2008-06-25)
      NASA's Phoenix Mars Lander will make a landing on Mars on May 25th, 2008. Following on from the overview of the Phoenix entry, descent and landing (EDL) system given at IPPW5, an initial look at the Phoenix landing will ...
