Voyager 1 & 2, Pioneer probes
hindi ko po alam
There are two, Pioneer 10 and Pioneer 11.
At the moment it has at least two: the GRAIL probes.
No, space probes are unmanned.
Space probes explore space for a quite obvious reason; they are SPACE probes. They probe space.

They have already sent two probes near Mercury: Mariner 10, and MESSENGER. The BepiColombo is a proposed joint mission between JAXA and ESA, which will launch a further two probes.
the names of the probes that explored the gas giants were the voagers two
In the movie roving mars they mentioned two space probes tat they sent out two mars with successful outcomes on the landing the two names were spirit and opportunity
I assume you are referring to methods of measuring small value resistances, as in locating short circuits on a PC card. Two probe is the method used by standard ohm meters. This works OK for most resistance values, as the resistance of the leads & probes is much lower than the resistance being measured. But when the resistance being measured gets very tiny (e.g. a few milliohms) it fails as the resistance of the leads & probe are of the same order of magnitude and are in series with it. Four probe solves this problem by using two probes connected to a current source to drive the resistance and a separate two probes connected to a precision voltmeter calibrated in milliohms. The voltage drop in the leads due to the test current does not get measured by the calibrated voltmeter, as it does in two probe method. There is no voltage drop in the measurement leads as the voltmeter is high impedance.

The two most well known ones are Voyager Probe and the Viking probe.
4 space probes
more than 40 probes
Space probes would be safer.
