A spherical probe was released by the Pioneer and began its journey towards Neptune.
Soon, the probe skimmed through Neptune's atmosphere, approaching the planet's surface.
This probe, specially designed by Jiang Cheng, can withstand extremely harsh conditions.
First, its spherical exterior can endure smaller impacts in Neptune's violent storms, preventing damage to the probe.
It's important to know that Neptune has the most violent storms in the Solar System, and not using a spherical design simply wouldn't work.
Besides the spherical exterior, the probe is also highly insulated against cold.
The insulation layer on the probe's surface, developed by Jiang Cheng, can withstand extremely low temperatures.
Neptune experiences temperatures of over minus two hundred degrees Celsius, and if the insulation isn't excellent, the internal components might freeze and malfunction.
