In 1998, about 100 researchers met twice to develop plans for the future in this research area. The results of these meetings
have been collected in a package titled ”A Roadmap for Fundamental Physics in Space”. A summary of the Roadmap will be presented
along with an overview of the current program. Research is being performed in Low Temperature and Condensed Matter
Physics, Laser Cooling and Atomic Physics, and Gravitational and Relativistic Physics. There are currently over 50 investigators
in the program of which 8 are being evaluated as potential flight experiments. The number of investigators is expected to grow
further during the next selection cycle, planned to start toward the end of this year. In the near future, our investigators will be
able to take advantage of long duration experimentation in Space using a suite of different carriers under development.

A parametric weight assessment of advanced metallic panel, ceramic blanket, and ceramic tile thermal protection systems
(TPS) was conducted using an implicit, one-dimensional (I-D) finite element sizing code. This sizing code contained models to
account for coatings fasteners, adhesives, and strain isolation pads. Atmospheric entry heating profiles for two vehicles, the
Access to Space (ATS) vehicle and a proposed Reusable Launch Vehicle (RLV), were used to ensure that the trends were not
unique to a certain trajectory. Ten TPS concepts were compared for a range of applied heat loads and substructural heat capacities
to identify general trends. This study found the blanket TPS concepts have the lightest weights over the majority of their applicable
ranges, and current technology ceramic tiles and metallic TPS concepts have similar weights. A proposed, state-of-the-art metallic
