FOR IMMEDIATE RELEASE

LATEST SHUTTLE FLIGHT MARKS 14^TH MISSION FOR SPACEHAB;
15^th MISSION TO FOLLOW IN AUGUST

Washington, D.C., May 19, 2000 - Today's launch of the Space Shuttle Atlantis from Kennedy Space Center in Florida marked SPACEHAB, Inc.'s (Nasdaq/NMS: SPAB) 14th mission in space and its second resupply mission to the International Space Station (ISS). The Space Shuttle Atlantis is carrying a SPACEHAB Logistics Double Module (LDM), Integrated Cargo Carrier (ICC), and SPACEHAB Oceaneering Space Systems (SHOSS) Box packed with equipment and supplies for the ISS.

This mission assures SPACEHAB's leading position in the growing space station resupply business. The company supported seven missions to resupply the Russian Mir space station and the first ISS resupply mission, which was launched last year. The company recently received a $21.6 million contract award from the National Aeronautics and Space Administration (NASA -- http://www.nasa.gov) to support a third ISS resupply mission, scheduled for launch in September.

"With these resupply missions, the development of our Enterprise™ commercial space station module, and the establishment of our new Space Media, Inc. subsidiary, SPACEHAB is opening the door to space commerce in the new millennium," said Dr. Shelley A. Harrison, SPACEHAB's Chairman and Chief Executive Officer. "Since our first Shuttle mission in 1993, we have been busy supporting people living and working in space - the astronauts and cosmonauts who use our modules on Shuttle missions," Harrison said. "Through television and Internet broadcasting from Enterprise™, we now will bring this unique experience to worldwide audiences here on Earth."

"We are excited about the successful launch of our 14^th mission and the prospect of our 15^th mission launching just four months from now," said SPACEHAB President David A. Rossi. "These resupply missions to the ISS are critical to the future of space exploration and development, and they provide SPACEHAB with a recurring source of revenue that is important to our business."

Cargo manifests for missions to Mir were subject to change just weeks before launch. (SPACEHAB carried cargo for both NASA and the Russian Aviation and Space Agency RASA on these missions. For more information on NASA's Space Shuttle and space station plans, see http://spaceflight.nasa.gov/index-m.html.) ISS resupply missions require a similar kind of flexibility. SPACEHAB was able to accommodate numerous changes in the STS-101 cargo manifest as mission plans evolved, including a late request to stow an Orbiter Replacement Unit fan and adaptive hardware in the LDM, a task completed on April 21 (three days before the original STS-101 launch date of April 24). The company also installed a grapple fixture in the SHOSS Box (an equipment stowage container attached to the top of the ICC) at the launch pad -- a program first for the ICC.

SPACEHAB can load up to a ton of late-access cargo once the Shuttle is on the launch pad. "If it can fit through the hatch of an orbiter or a space station module, then we will figure out how to stow it and deliver it," said Rossi.

After Atlantis docks with the ISS, space-walking astronauts will transfer parts for a Russian-built crane from the SHOSS Box to the ISS. Astronauts also will transfer a variety of crew supplies and equipment from the LDM to the ISS, including replacement batteries for the Russian FGB module, a common-berthing-mechanism centerline camera system, crew care packages, an early portable computer system, an IMAX 3-D camera, and exercise devices. SPACEHAB's module is tightly packed for this mission, including overhead and subfloor space. The ICC is fully packed as well, carrying such items as an Articulated Portable Foot Restraint within the SHOSS Box.

Founded in 1984 and with more than $100 million in annual revenue, SPACEHAB is a leading provider of commercial space services. 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. The company also supports astronaut training at NASA's Johnson Space Center in Texas and provides commercial satellite processing services for Boeing's (NYSE: BA) Delta and Lockheed Martin's (NYSE: LMT) Atlas launch vehicles near Kennedy Space Center in Florida.

This release contains forward-looking statements that are subject to certain risks and uncertainties that could cause actual results to differ materially from those projected in such statements. Such risks and uncertainties include, but are not limited to, whether the company will fully realize the economic benefits under its NASA and other customer contracts, the timing and mix of Space Shuttle missions, the successful development and commercialization of new space assets, technological difficulties, product demand, timing of new contracts, launches and business, market acceptance risks, the effect of economic conditions, uncertainty in government funding, the impact of competition, and other risks detailed in the Company's Securities and Exchange Commission filings.
