activities for the discovery and characterization of near-
Earth objects.
Spacehab
A small laboratory module, similar to the European
Spacelab in concept, that is designed to be carried in the
payload bay of the Space Shuttle to provide extra working
space in which astronauts can carry out experiments.
Its first, 16-day mission, aboard STS-107, was scheduled
for the second half of 2002.
Spacelab
A modular, reusable scientific laboratory, built by ESA
(European Space Agency) and carried into orbit on
numerous missions between 1983 and 1998 by the Space
Shuttle. Scientists from about a dozen nations used it to
Spacelab Missions
conduct research on a wide variety of subjects under
conditions of microgravity. Spacelab consisted of an
enclosed pressurized module, where the crew worked,
and smaller unpressurized pallets. The latter carried telescopes
and other instruments that required direct exposure
to space or did not need a human operator. Some
Spacelab missions were dedicated to a particular field,
such as life sciences, materials science, astronomy, or
Earth observation, while others were multidisciplinary.

Spacepac
A political action committee, based in Washington,
D.C., that is affiliated with the National Space Society.
Spacepac carries out research on issues, policies, and
candidates aimed at favorably influencing policy with
