The main purpose of this award was to supply a platform for the airborne measurements of gases associated with the CO2
Budget and Regional Airborne Study (COBRA). The original program was to consist of three field programs: the first was to
be in 1999, the second in 2000, and the third in 2001. At the end of the second field program, it was agreed that the science
could better be served by making the measurements in northern Brazil, rather than in North America. The final North American
program would be postponed until after two field programs in Brazil. A substantial amount of effort was diverted into making
plans and preparations for the Brazil field programs. The Brazil field programs were originally scheduled to take place in the
Fall of 2002 and Spring of 2003. Carrying out the field program in Brazil was going to logistically much more involved than
a program in the US. Shipping of equipment, customs, and site preparations required work to begin many months prior to the
actual measurement program. Permission to fly in that country was also not trivial and indeed proved to be a major obstacle.
When we were not able to get permission to fly in Brazil for the 2002 portion of the experiment, the program was pushed back
to 2003. When permission by the Brazilian government was not given in time for a Spring of 2003 field program, the
experiment was postponed again to begin in the Fall of 2003.

The Materials Science Program is structured so that NASA s headquarters is responsible for the program content and
selection, through the Enterprise Scientist, and MSFC provides for implementation of ground and flight programs with a
Discipline Scientist and Discipline Manager. The Discipline Working Group of eminent scientists from outside of NASA acts
in an advisory capacity and writes the Discipline Document from which the NRA content is derived. The program is reviewed
approximately every three years by groups such as the Committee on Microgravity Research, the National Materials Advisory
Board, and the OBPR Maximization and Prioritization (ReMaP) Task Force. The flight program has had as many as twenty-six
principal investigators (PIs) in flight or flight definition stage, with the numbers of PIs in the future dependent on the results
of the ReMaP Task Force and internal reviews. Each project has a NASA-appointed Project Scientist, considered a half-time
job, who assists the PI in understanding and preparing for internal reviews such as the Science Concept Review and
Requirements Definition Review. The Project Scientist also insures that the PI gets the maximum science support from MSFC,
represents the PI to the MSFC community, and collaborates with the Project Manager to insure the project is well-supported
and remains vital. Currently available flight equipment includes the Materials Science Research Rack (MSRR-1) and
Microgravity Science Glovebox. Ground based projects fall into one or more of several categories. Intellectual Underpinning
of Flight Program projects include theoretical studies backed by modeling and computer simulations; bring to maturity new
research, often by young researchers, and may include preliminary short duration low gravity experiments in the KC-135
aircraft or drop tube; enable characterization of data sets from previous flights; and provide thermophysical property
determinations to aid PIs. Radiation Shielding and preliminary In Situ Resource Utilization (ISRU) studies work towards
future long duration missions. Biomaterials support materials issues affecting crew health. Nanostructured Materials are
currently considered to be maturing new research, and Advanced Materials for Space Transportation has as yet no PIs. PIs are
assigned a NASA Technical Monitor to maintain contact, a position considered to be a 5 percent per PI effort. Currently 33
PIs are supported on the 1996 NRA, which is about to expire, and 59 on the 1998 NRA. Two new NRAs, one for Radiation
Shielding and one for Materials Science for Advanced Space Propulsion are due to be announced by the 2003 fiscal year.
MSFC has a number of facilities supporting materials science. These include the Microgravity Development Laboratory/
SD43; Electrostatic Levitator Facility; SCN Purification Facility; Electron Microscope/Microprobe Facility; Static and
Rotating Magnetic Field Facility; X-Ray Diffraction Facility; and the Furnace Development Laboratory.
