Glossary T

A telescope is an instrument that is used to observe objects in space, such as planets, stars galaxies, and other celestial bodies. Telescopes are used to collect light from these objects and to focus it onto a detector, such as a camera or a spectrograph, in order to study their characteristics and to learn more about the universe.

Telescoping in the aerospace context refers to the ability of a structure to extend or retract in length. This feature allows for a more compact storage or transportation and a larger operational size.

Deutsch: Temperatur / Español: Temperatura / Português: Temperatura / Français: Température / Italiano: Temperatura /

Temperature is a physical quantity that expresses quantitatively the perceptions of hotness and coldness. Temperature is measured with a thermometer.

Thermometers are calibrated in various temperature scales that historically have relied on various reference points and thermometric substances for definition. The most common scales are the Celsius scale with the unit symbol °C (formerly called centigrade), the Fahrenheit scale (°F), and the Kelvin scale (K), the latter being used predominantly for scientific purposes. The kelvin is one of the seven base units in the International System of Units (SI).
