RENOWNED PLANT RESEARCHER ROGER BEACHY
JOINS SPACEHAB's SCIENCE ADVISORY BOARD

Washington, D.C., June 20, 2000 - SPACEHAB, Inc. (Nasdaq/NMS: SPAB), a leading provider of commercial space services, today announced that Dr. Roger N. Beachy, president of the Donald Danforth Plant Science Center in St. Louis, Missouri, has joined the company's Science Advisory Board. Earlier this year, SPACEHAB and the Danforth Center signed a memorandum of understanding (MOU) with the Institute of Molecular Agrobiology (IMA) in Singapore and Monsanto Company to conduct joint life sciences research in space.

Dr. Beachy, a member of the National Academy of Sciences, is internationally known for his work on virus-resistant plants. "We are pleased and honored to have Dr. Beachy join our Science Advisory Board," said Dr. Bernard A. Harris, Jr., M.D., SPACEHAB's Vice President for Science and Health Services. "Dr. Beachy brings a wealth of knowledge, especially in the critical areas of plant science and biotechnology research."

SPACEHAB established its Science Advisory Board in 1997 to provide scientific expertise on emerging technology and applications for space research. The board is engaged in canvassing the science and technology community regarding research endeavors that may be viable in space. The board also supports science and education outreach around the world.

From 1991 to 1998, Dr. Beachy headed the Division of Plant Biology at The Scripps Research Institute in La Jolla, California. From 1978 to 1991, Dr. Beachy was on the faculty of Washington University's Biology Department and headed the university's Center for Plant Science and Biotechnology. His work at Washington University, in collaboration with Monsanto, led to development of the world's first genetically altered food crop, a virus-resistant tomato.

Dr. Beachy holds a Ph.D. in plant pathology from Michigan State University (1973) and a B.A. in biology from Goshen College in Goshen, Indiana (1966). He is a member of many scientific societies, including the American Society for Plant Physiology, American Society for Biochemistry and Molecular Biology and American Society for Virology.

The Donald Danforth Plant Science Center, a nonprofit organization founded in 1998, is the product of a partnership involving government, industry, and academia. Its mission is to increase understanding of plant biology; facilitate the development and commercialization of promising technologies and products; and contribute to education and training.

SPACEHAB is the first company to commercially develop, own and operate habitable modules that provide laboratory facilities and logistics resupply aboard NASA's Space Shuttles. SPACEHAB has flown its habitat modules and cargo carriers on 14 Space Shuttle missions thus far. The company also supports astronaut training at NASA's Johnson Space Center in Houston, Texas, and provides commercial satellite processing services for Boeing's Delta and Lockheed Martin's Atlas launch vehicles in North America.

• The Danforth Center, a nonprofit independent research institution named after the founder and former president of Ralston Purina in St. Louis, was established in 1998 to increase understanding of plant biology, sustain biological productivity, facilitate the development and commercialization of technologies and products, and contribute to education and training. Global outreach is a primary goal.
• The Center aims to facilitate interdisciplinary research in genetics, chemistry, cell biology, biochemistry, computational genomics, and structural biology.
• Partners in the Center include Monsanto, the Missouri Botanical Garden, Purdue University, University of Illinois at Urbana-Champaign, University of Missouri-Columbia and Washington University (St. Louis). The Danforth Foundation (headed by former U.S. Senator John Danforth, son of Donald Danforth) and the State of Missouri provide additional support.

SPACEHAB, Space Media™, and S*T*A*R*S™:

• Established in 1984 and with more than $100 million in annual revenue, SPACEHAB, Inc., is a leading provider of commercial space services and the first company to commercially develop, own and operate habitable modules that provide laboratory facilities and logistics resupply aboard NASA's Space Shuttles. SPACEHAB also trains Space Shuttle astronauts, manufactures and operates mockups used for crew training, and provides commercial payload processing services.
• SPACEHAB has flown its modules on 14 Space Shuttle missions thus far, delivering services to NASA and other customers worldwide on a commercial, fixed price basis.
• SPACEHAB is developing a space station habitat module called Enterprise™, which will be the world's first commercial real estate in space. Enterprise™ will be outfitted with a multimedia production facility and attached to the International Space Station.
• Space Media, Inc. (SMI™), a subsidiary of SPACEHAB, will be producing space-focused content aboard Enterprise™ for television broadcasting and Internet distribution.
• SMI™ operates the S*T*A*R*S™ program. S*T*A*R*S™ is an acronym for Space Technology And Research Students, a global education program that allows students to design experiments which will fly in space. Students monitor S*T*A*R*S™ experiments on the Internet. Plans are under way to fly S*T*A*R*S™ experiments for students in Australia, China, Israel, Japan, Singapore, and the U.S.

• On January 13, 2000, in Singapore, SPACEHAB, the Donald Danforth Plant Science Center, the Institute of Molecular Agrobiology and Monsanto Company signed a memorandum of understanding (MOU) to engage in joint space research.
• The partners will develop a protein crystal growth experiment to fly on NASA's Space Shuttle mission STS-107 in 2001. Researchers will use a High-Density Protein Crystal Growth Facility, provided by the Center for Macromolecular Crystallography at the University of Alabama-Birmingham.
• Protein crystal growth has been the single most important commercial use of microgravity to date. Researchers can determine a protein's structure by x-ray diffraction from crystals of that protein; such knowledge is useful in designing new drugs, for example. In the microgravity environment of space, researchers can grow larger and purer protein crystals that yield better diffraction results.
• In addition to collaborating on their own space-based experimentation, signatories to the MOU will provide a S*T*A*R*S™ program for students in Singapore and Missouri that will culminate in the flight of an experiment on the Space Shuttle.
