Takeoff is the phase of flight in which an aerospace vehicle leaves the ground and becomes airborne. For aircraft traveling vertically, this is known as liftoff.

In the aerospace context, tape is a type of adhesive material that is used to hold, secure, or seal various components or materials together.

Taxi is the movement of an aircraft on the ground under its own power. The process is called taxiing.

The taxiway is the part of an airport used for taxiing, which links the runways with the terminals and hangars.

TDRSS stands for the Tracking and Data Relay Satellite System. TDRSS is a system of communication satellites that are used by NASA and other organizations to provide communications and data services for spacecraft, aircraft, and other systems.

Technology refers to the tools, techniques, and processes that are used to create, produce, and transmit goods and services. It includes the knowledge and skills required to design, develop, and use technological systems and devices.

In the aerospace context, telecommunications refers to the transmission of information, such as data, voice, or video, over long distances using electronic or electromagnetic signals. This can be accomplished using a variety of technologies, including satellite systems, radio waves, and fiber optic cables.

Telemetry refers to the process of remotely measuring and collecting data from aerospace vehicles or other objects, such as aircraft, rockets, satellites, or spacecraft. This data is typically collected using sensors and transmitted to a ground station or other remote location for analysis and monitoring.

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.

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).

The terminal is a building at an airport where passengers transfer from ground transportation to the facilities that allow them to board aircraft; also, a building at an airport where freight is transferred from ground transportation to aircraft.

Territory in the space industry context refers to the region of space over which a country or organization asserts jurisdiction or control. In outer space, there are no natural boundaries or borders, but the concept of territory becomes relevant when it comes to issues of space exploration, resource utilization, and legal frameworks governing outer space activities. This article will delve into the significance of territory in the space industry, provide examples of territorial claims and disputes, and discuss similar concepts related to the jurisdiction and control of celestial bodies and regions in space.

THEMIS (Time History of Events and Macroscale Interactions during Substorms) is a NASA mission designed to study the causes of auroral substorms, which are sudden brightenings of the aurora borealis (northern lights) and aurora australis (southern lights) that occur in the Earth's upper atmosphere.

In the aerospace context, the thermosphere is a layer of the Earth's atmosphere that lies above the mesosphere and below the exosphere.

Thrust is a reaction force described quantitatively by Newton's third law. When a system expels or accelerates mass in one direction, the accelerated mass will cause a force of equal magnitude but opposite direction to be applied to that system.

In the aerospace context, a thruster is a device that produces a force in order to propel an object through space. Thrusters are used in a variety of aerospace applications, including spacecraft, satellites, and missiles.

In the aerospace context, Thuraya is the name of a mobile satellite communication company that provides voice and data services to a wide range of customers, including individuals, businesses, governments, and NGOs. The company was founded in 1997 and is based in the United Arab Emirates (UAE).

Titan is the largest moon of Saturn, and is of significant interest in the aerospace context because of its thick atmosphere, which is composed mostly of nitrogen, and its surface features, which include lakes and seas of liquid methane and ethane.

Titania is the largest of the five major moons of Uranus. It was discovered by William Herschel in 1787, and it is the eighth largest moon in the solar system. It is primarily composed of water ice, and it has a heavily cratered surface with large rift valleys, and also it has a diameter of about 1,578 km (981 mi).
