No, because there is no such ting as a planet with zero gravity.
A planet's gravity affects the trajectory of a space probe by pulling it towards the planet, causing the probe to alter its course. The probe's speed and direction can be influenced by the planet's gravity, leading to changes in its orbit or flight path. Scientists must account for the planet's gravitational pull when planning the probe's trajectory to ensure it reaches its intended destination.
As space probe is carried into space using rockets and afterward can maneuver using thrusters, sometimes gaining speed using the gravity of a planet. Once a space probe has been set on the right trajectory it does not have to do much; there is no air resistance to slow it down and gravity from the sun and planets is already taken into account.
That was "Voyager 2".
Voyager II is the first successful space probe that reached the outer planets or Jovian Planets. It is in the rule of probes that they should not reach the outer planets because it is too far and their probes might malfunction. But this Voyager II probe had a successful flight to the outer planets.

A pH probe is a device used to measure the acidity of a solution.
By the gravity pull
The four-probe method is used to measure resistivity because it eliminates the effects of contact resistance and lead resistance that can distort measurements in the two-probe method. In the four-probe setup, two probes are used to source current while the other two measure the voltage drop, ensuring that voltage measurements are not influenced by the resistances of the probes and contacts. This results in more accurate and reliable measurements of the material's intrinsic resistivity.
NASA has launched the Kepler mission to search for new planets.
For the design of the probe an understanding of gravity is not required. However, to get the probe into space and into a stable orbit round a chosen body an understanding of gravity is required. Thus it is the launch vehicle design where an understanding of gravity is needed.
The space probe landed successfully on Mars, where it collected astrological and atmospheric data.
The Dawn space probe will begin orbiting Ceres in February 2015. The New Horizons probe will do a flyby of Pluto in June 2015. No other dwarf planets will be visited that year.
