Stop to consider them for what purpose? Thinking they're cool? Yeah they're cool. But they have very little to do with interstellar travel, in the way that a canoe has little to do with investigating deep-sea vents.

We call it a "space" station. It's a glorified LEO station.

It's more like a laboratory, and less like a ship/bus/train "station".

> Space Station that lasts 25 years

A small station, hosting a small number of people, orbiting very close to the surface of the Earth.

> 3,000 satellites providing Internet Service

…very close to the surface of the Earth.

> Mars rovers that run for 10+ years

On the closest planet to Earth that our equipment can survive on. Notably, we have nothing but melted slag on Venus.

> Flying helicopters on Mars

On the closest planet to Earth that our equipment can survive on.

I don’t mean to detract from the achievements of our space programs. But we have to be realistic: we’re exploring the easiest bits of our local neighborhood, that’s all.

The Kurzgesagt video on teraforming Venus is interesting. It only takes a thousand years, assuming perfect execution.
