No talk of atmospheric flight and landings on planets with an atmosphere.
Only airless planets?
I think planetary landing is great but I really do expect it to eventually be extended to all planets and even rocks.
(maybe even gas giants depending on how generalized the atmosphere tech will be). Especially now that Star Citizen also threw their hat into the ring in regards to PG planets.![]()
Not to be the devils advocate or anything but exactly how would you land on a gas giant which has no solid mass to land on... there would be no settlements nor any possibility to land, even less so to drive your SRV. Also, many gas giants have massive gravity so flying low (along surface or even within the gas itself) might even be suicidal.

Gas giants are large, but not particularly dense, hence the gravity is not the issue. Achenar 3 has 6G of gravity, whereas Jupiter only has a gravity of 2.5G.Not to be the devils advocate or anything but exactly how would you land on a gas giant which has no solid mass to land on... there would be no settlements nor any possibility to land, even less so to drive your SRV.

The real risk is the pressure of the gas and the wind - the top speed of a speed Cobra is 465m/s, or 1674km/h. Winds on Neptune have been observed up to 2,100 km/h. In short, if you don't hit it first time, you could end up either painted on the wall of the station or blown about like a leaf.
I guess if there were more moderate regions in the atmosphere, such as calmer regions in highly-banded gas giants, you could have floating cities. The tech for it is already 100 years old. We call them airships.
Wikipedia said:The temperature and pressure inside Jupiter increase steadily toward the core, due to the Kelvin–Helmholtz mechanism. At the "surface" pressure level of 10 bars, the temperature is around 340 K (67 °C; 152 °F). At the phase transition region where hydrogen—heated beyond its critical point—becomes metallic, it is calculated the temperature is 10,000 K (9,700 °C; 17,500 °F) and the pressure is 200 GPa. The temperature at the core boundary is estimated to be 36,000 K (35,700 °C; 64,300 °F) and the interior pressure is roughly 3,000–4,500 GPa.
So when you reach the solid surface, you are facing 10.000 Kelvin, and a pressure of 200 GPa (2.000.000 Bar).
That's 2039432 kg/cm² (or 29007547 lb/in² for you non-metrics) .. or 2039 metric tonnes of pressure per cm².
Your starship, and your little SRV, will either be burned to spacedust or crumbled together like a piece of ricepaper... or both.

You mean the starship that we fly into the corona of suns to refuel? You know, the part of the sun that it is millions of kelvin in temperature?![]()
