Deep space probe
A deep space probe was a long-range unmanned space probe used to study phenomenon in deep space, far beyond the range of manned exploration.

20th century
Earth deep space probes, launched in the 20th century, included such NASA probes as Pioneer 10 and Voyager 6 of the Voyager series. (, )

21st century
Earth deep space probes of the 21st century included the Nomad probe launched in 2002 and the first warp probe Friendship 1 launched in 2067. Both were sent into deep space to seek out alien life. (; )

22nd century
Deep space probes of the 22nd century included Quadros 1, sent out to chart the stars of the Gamma Quadrant. ()

23rd Century
''In the alternate reality, Starfleet used the Magellan probes to chart the Necro Cloud. One of these probes was captured by Krall in 2263 and used to link up with the computers aboard the Enterprise and Starbase Yorktown.()

24th century
The deep space probes used by Starfleet and the Federation in the 24th century had radioactive material in their casing. The radiation was strong enough to interfere with normal comm badge signals and cause radiation poisoning. The Romulan Star Empire was known to monitor the telemetry sent by the Starfleet deep space probes. ()

The Vega 9 probe was a deep space probe launched by Starfleet to study the Beta Stromgren star, as it entered the final stages of an alternating cycle of expansion and collapse that would result in a supernova explosion. Beta Stromger was at the time 23 parsecs beyond the furthest manned exploration to that region. The probe reached the system in 2366 and discovered the "Tin Man" orbiting Stromgren. ()

In 2370, a deep space probe went off course and crash landed on Barkon IV over a hundred kilometers from the nearest settlement. Lt. Commander Data was sent from the  to retrieve the wreckage as he was immune to the radiation. Data collected the radioactive fragments of the probe casing, but as he was attempting to download the sensor logs from the on-board computer of the probe, he suffered a power surge, that overloaded his positronic matrix resulting in amnesia.
