I’ve been to the Arctic Circle in Norway (It runs around the Earth, so you’d also find parts of Sweden, Finland, Alaska, and Siberia, etc. within the circle). People actually live within lower bands of it, but nothing grows within the top bands of it.
Now, Mars is millions of miles away from Earth, and you still believe you could grow life there? Parts of the Earth just above and below the equator get unbearably hot in summer, while Venus is millions of miles closer to the Sun. No point in exploring any of those.
With Vo and Vio/IP traffic over the intercontinental optical- fiber submarine cable, even the demand for communications and TV satellites is no longer there. Inmarsat ( covers most of the Earth, except for the poles) is used by marine vessels, whereas Iridium is used by different government agencies for emergency communications (the only constellation of satellites that covers the entire earth, including the poles).
The navigation satellites are launched once every 5-20 years.
Most of the satellites are launched by China, Russia and India (cheaper alternatives), and only a few by Space X. It is a very saturated market, with the supply exceeding the demand.
Space tourism, might just be fad just like the initial space travel and lunar landings.
I mean how many people would risk their lives for a look at the Earth from space, when a view from the TV and even high-altitude private jets is fairly good? I could see the curvature of the Earth, even from a Lear Jet. Rocket motors are still not very safe.
The space industry is going private because there really isn’t anything out there.
The nearest planets that can sustain life are light years away. A light year is the distance you would travel in a year while travelling at 1.8 million KMs/min. Now that would be 9.33 trillion kilometers in a year. The best rockets can only do 345.6 million kilometers in a year. So it would take 9.33 trillion/ 345.6 million = 26,996.5 years in a rocket to travel just one light year. This isn’t humanly possible with the prevailing technology.
Mars isn’t going to heat up anytime soon, while mercury isn’t going to cool anytime soon.
With the optic-fiber marine cable laid between the continents, there isn’t much demand for communication satellites.
Voice and video data are both sent over the intercontinental submarine cable, so there’s not even much demand for satellites broadcasting TV.
I wonder if there is a future for the space industry!
