| Description: The type attribute classifies the instrument host. When more than one value is correct, the value with the finest granularity should be selected. That is, choose "rover" rather than "spacecraft" when both would be correct since rover more narrowly defines the type of instrument host. |

| Permissible Value(s) | Value | Value Meaning |
| | Aircraft | An airborne observatory carried on a powered, heavier than air vessel supporting observations, measurements, and scientific experiments during flight. |
| | Balloon | A balloon-borne observatory, typically consisting of a gondola structure carrying one or more telescopes and instruments, borne aloft by an unpowered or minimially powered lighter-than-atmosphere balloon for a limited observing period. |
| | Earth Based - *Deprecated* | The Instrument Host is classified as being of type Earth Based |
| | Earth-based - *Deprecated* | The instrument host is on or near the surface of Earth (no more than 100 km altitude above the surface). |
| | Lander | A spacecraft designed for descent to and operation at a single fixed point on the surface of a celestial body. |
| | Rover | A spacecraft designed for descent to and mobile operation on the surface of a celestial body. |
| | Spacecraft | A vehicle designed for travel in outer space ('outer space' is the region more than 100 km above the Earth's surface, a convention accepted in many contexts -- see http://en.wikipedia.org/wiki/Outer_space). |
| | Suborbital Rocket | A Suborbital Rocket is an instrument-carrying rocket designed to take measurements and perform scientific experiments during its sub-orbital flight. |
