Answer:
When designing a landing pod tailored to withstand Neptune's harsh atmosphere, we need to understand its most hostile features:
- cold temperatures of -240° to -330°F
- high pressure as you move into the clouds (up to 10,000 bars)
First, to withstand the atmosphere's cold temperatures, a landing pod would need thick insulation to keep heat inside the pod. Second, it would need structural rigidity to withstand the high pressure as it moves towards the planet's surface.
