| Astrobiology |
The
study of the living universe. Provides a foundation for a multidisciplinary
study of the origin and distribution of life in the universe,
including the role of physical forces, planetary atmospheres,
and ecosystem interaction in the evolution with living systems. |
| Astro
materials |
The
natural, nonbiological materials that constitute the solid bodies
of the solar system other than Earth, including planets, satellites,
asteroids, comets, and dust. These materials may be studied
in situ in their place of origin, collected by missions for
return to Earth, or brought to Earth by natural phenomena (meteorites,
cosmic dust). |

| El
Niño |
A
climate disturbance occurring every 2 to 5 years in the Pacific
Ocean. A region of warm water forms in the western Pacific and
moves toward South America, altering weather and rainfall patterns,
wind directions, and even the jet stream. El Niño events
contribute to floods and droughts in the Americas, Africa, and
Australia. |

| Microgravity
research |
Area
of scientific application and commercial research concerned
with the identification and description of the effects of reduced
gravitational forces on physical and chemical phenomena. Microgravity
research probes a new parameter in space where gravitional acceleration
no longer is equal to 1 g and, instead, can approach values
that are orders of magnitude lower. |
