Probes

Starfleet standard general use of probes, is divided into nine classes, arranged according to sensor types, power, and performance ratings. The features common to all nine are spacecraft frames of gamma moulded duranium-tritanium and pressure-bonded lufium boronate, with certain sensor windows of triple layered transparent aluminium. Sensors not utilizing the windows are affixed through various methods, from surface blending with the hull material to imbedding the active detectors within the hull itself.



All nine classes are equipped with a standard suite of instruments to detect and analyzes all normal EM and subspace bands, organic and inorganic chemical compounds, atmospheric constituents, and mechanical force properties. While all are capable of at least surviving a powered atmospheric entry, only three are designed to function for extended periods of aerial manoeuvring and soft landing. Many of the probes also include varying degrees of tele-robotic operation capabilities to permit real time control and piloting of the probe. This permits the investigation team to remain on board the Starship while exploring what might otherwise be a dangerous hostile or otherwise inaccessible environment.

Atmospheric probe



The Defiant was trapped inside a gas giant's atmosphere in DS9: "Starship Down", this type of probe was modified and used to destroy a Jem'Hadar attack ship. I maybe a variation of the Class 3 type in a new casing?

Egg Type

An instrumented sensor probe, designed by Dr. Paul Stubbs to record the decay of neutronium expelled during a stellar explosion.
Dr. Stubbs, who nicknamed his brainchild "the Egg," worked on it for twenty years before successfully launching it from the Enterprise-D at the Kavis Alpha Sector in 2366.
The full-scale egg prop was a modification of the virus containment device originally built for TNG "The Child". TNG "Evolution" ; Star Trek Encyclopedia



Launching the Probes.



Federation Interface Probe



This is a Robotic device that uses remote telepresence technology to permit a person to work in hazardous environments while remaining at a safer location. In 2370,
a interface probe was sent into the U.S.S. Raman, allowing Geordi La Forge to see and feel his way around the ship with the assistance of the interface unit.
TNG "Interface" ; Star Trek Encyclopedia

Federation Multispatial Probe



Autonomous remote sensing device built by the crew of the Voyager in 2375.
The probe was equipped with Borg shielding technology that successfully protected the probe even when it ventured
into the atmosphere of a gas giant. VOY "Extreme Risk" ; Star Trek Encyclopedia
