SUMMARY PURPOSE AND SCOPE:
--------------------------


This project provides the third and final increment of the Earth Systems Science Building (ESSB)
at the Goddard Space Flight Center (GSFC).  The facility will provide approximately 290,000
square feet to house civil service, contractor, and visiting scientist personnel conducting
interdisciplinary Earth science and research into global change.  This facility is located
adjacent to the Earth Observing System Data Information System (EOSDIS) Facility and will support
the Earth Observing System (EOS) program by data analysis, assimilation, and instrument and
algorithm development.




PROJECT JUSTIFICATION:
----------------------


The United States has taken the leadership role in one of the largest Earth Science enterprises--
Global Change research.  The Earth Observing Systems (EOS) Program is a critical component of
this effort.  It will contribute principal Earth observing, data processing and archiving, and
Earth systems scientific research capabilities essential to conduct this research.  Goddard Space
Flight Center is NASA's lead Center for EOS, with responsibility for development of Earth
Observing capabilities including the Earth Observing System Morning Crossing (EOSAM) and Earth
Observing System Afternoon Crossing (EOSPM) spacecraft; GSFC-sponsored NASA facilities class
instruments; Earth Science mission operations; principal or co-investigators for a number of EOS-
related scientific investigations; Land Remote-Sensing Satellite (LANDSAT); and processing,
archiving, and disseminating GSFC-related EOS data.


The Earth System Science Building (ESSB) brings together vital elements of GSFC's substantial
Earth Sciences talent in facilities dedicated to the conduct of EOS/Global Change research.  This
is essential to facilitate and promote the interdisciplinary scientific research required to
achieve EOS/Global Change research goals.  The ESSB will also provide a venue for collaboration
between NASA and other scientists engaged in Global Change research.  The proximity of the ESSB
Facility to the EOSDIS Facility will provide ready access to the GSFC EOS Distributed Active
Archive Center (DAAC), the central repository (located within the EOSDIS Facility) for all GSFC
EOS-related data.



IMPACT OF DELAY:
----------------


If the ESSB facility is delayed, it will adversely impact the analysis and understanding of EOS
data, as well as delay the development of instrumentation and algorithms for future Earth Science
missions.




PROJECT DESCRIPTIONS:
---------------------


The 290,000 square foot facility is located on the east side adjacent to the EOSDIS Facility at
Greenbelt and Soil Conservation Service Roads.  The first increment (FY 1994) provided for site
development/utilities, and included extension of basic utilities infrastructure to the ESSB site,
expansion of EOSDIS utility plant including provision for backup diesel electric power, and
construction of ESSB footings and foundations.  The second increment (FY 1995) will provide the
ESSB shell and procurement of building architectural, mechanical and electrical long lead items.
This third and final increment will provide for installation of the architectural, mechanical,
and electrical long lead items; construction of building interior, partitioning, and finishes;
and completion of the facility.

SUMMARY PURPOSE AND SCOPE:
--------------------------


This project provides for the construction of a 1,600 square meter addition to the Microgravity
Development Laboratory, Building 4493.  The addition will house ground control experiment
laboratories (GCEL) and clean rooms for the development of flight hardware.  The space provided
will also be used for the processing of microgravity experiment flight hardware before and after
scheduled flights.  The existing structure is not large enough to accommodate these efforts.



PROJECT JUSTIFICATION:
----------------------


The Microgravity Experiments Project Office is establishing a Microgravity Development Laboratory
facility in which to conduct microgravity science and applications research.  This project will
increase the capabilities for the facility to support microgravity experiment development,
processing of flight hardware, and in-flight operations.  The facility will include GCEL,
hardware clean rooms, a Microgravity User Operations Facility, and a Microgravity Data Center and
Archive.  Building 4493 has been selected to house these activities, however, it is too small to
operate them all.  The proposed addition will provide space for the GCEL, and for clean room,
laboratory, and office activities.  The remaining activities will be housed in the existing
portion of the building.  These activities are currently being conducted at inadequate and remote
locations at MSFC or at off-site contractor locations.  This marginal support creates an
unnecessary risk to the cost, schedule, and quality if scientific development that can be avoided
by constructing this addition.  There is no contiguous space at MSFC suitable for the entire
activity.  Restoration and outfitting, with unavoidable duplication of equipment, of the three to
four locations required creates a need for supplemental work force and would require frequent
movements if flight hardware between the locations,  In addition internal development time frames
would be increased along with greater risk of damaging the hardware during the moves.



IMPACT OF DELAY:
----------------


Deferring this project will adversely impact the development of microgravity experiments
available for currently manifested Shuttle flights as planned for the space station.  By not
constructing the facility as planned, the required timeliness and quality of supporting research
can not be attained at the lowest cost and the underlying science infrastructure will be
degraded.



PROJECT DESCRIPTION:
--------------------


The project provides for the construction of an approximately 1,600 square meter addition to the
west end of Building 4493.  Office areas, conference rooms, corridors, laboratories, and work
areas requiring no special construction will have painted gypsum board walls and mineral board
suspended acoustic ceilings.  Certain laboratory areas will require a variety of special features
ranging from raised computer flooring to prefabricated clean room components.  Clean rooms will
generally be constructed using wall panels consisting of porcelain enamel bonded to a rigid
backing material.  The project provides for the installation of light-duty cranes; high purity
air and high pressure gas services; electrical power and data distribution systems; and heating,
ventilation, and air conditioning (HVAC) systems.  High bay space with 6 meter clear height will
be provided along with support areas such as airlocks, storage space, and dressing rooms.  An
office area will be provided to support science investigators.

SUMMARY PURPOSE AND SCOPE:
--------------------------


This project provides funding for modernization of the Unitary Plan Wind Tunnel Complex to
improve productivity, reliability, and the quality of test results.  The project will provide new
automated tunnel and model support controls; automated controls for tunnel auxiliaries; flow
quality improvements in the 11 by 11 foot Transonic Wind Tunnel (11-ft TWT); repair or
replacement of aging facility systems; and repair of weld defects in the pressure shell to allow
recertification.



PROJECT JUSTIFICATION:
----------------------


The Unitary Plan Wind Tunnel (UPWT) is a vital National high-speed tunnel facility consisting of
one transonic and two supersonic test sections and supporting auxiliary equipment.  This facility
is the most heavily used wind tunnel complex in NASA.  However, the facility's productivity is
limited by the 1950's era control systems and the increasing frequency of equipment breakdowns
due to age and heavy use.  Modernization is needed now to improve productivity, data quality, and
reliability.  This complex has been operated on three-shifts-per-day basis since 1956, with
minimal improvements.  Tunnel downtime resulting from equipment and control failures has caused
major delays to important aircraft projects.  Tunnel backlog of testing exceeds two years.  Lack
of modern data acquisition equipment results in over half of tunnel tests being concluded before
all needed data is acquired.  Comparable foreign facilities have shown two to three times the
productivity achieved in this wind tunnel complex.


Since it was placed in service in 1956, the UPWT Complex has contributed to the development of
almost every U.S. developed military and civil aircraft flying or nearing service in its speed
regime of Mach 0.3 to 3.5, as well as every U.S. manned spacecraft.  It has provided valuable
experimental results for development of military aircraft such as F-100, F-106, F-111, F-14,
F-15, F-16, F-18, F-22, B-58, B-70, B-1, A7, and EA-6; and for commercial transports, including
McDonnell Douglas DC-8, 9, 10, 11, 87V/88V, and 90, as well as Boeing 727, 747, 757, 767, and
777.


Repair or replacement of tunnel components that have reached the end if their useful life is
required.  Also, the welds in the tunnel shell contain defects typical of 1950's technology and
must be repaired and the pressure shell recertified.



IMPACT OF DELAY:
----------------


Failure to modernize this facility will increase the delay in acquiring critical test data.  The
existing (unmodified) facility will continue to fail more frequently, requiring the use of
alternate testing resources in Europe and other countries.  This in turn, will reduce or delay
improvements to U.S. commercial and military aircraft, and will significantly increase the cost
of testing.  In addition, NASA's leadership role in aeronautical research and development will
diminish resulting in further degradation of the United States' world leadership in aviation.







PROJECT DESCRIPTION:


This increment of work will complete controls modernization, automation, and replacement; flow
quality improvements and pressure vessel shell repair.  The total project includes refurbishing
and providing automated controls for the tunnel systems, model support systems, make-up air 
system, and compressor lubrication system; enlarging and modernizing the control rooms; and 
installing flow quality improvements in the 11-ft TWT.  The project also includes refurbishing,
reparing, or replacing major components, including the cooling tower, large electrical switch-
gear, and make-up air system; and repairing weld defects in the pressurized portions of the 
tunnel circuits and make-up air system and recertifying the pressurized systems for safe operation.
