Elon Musk wants to stream the Internet from space – The Motley Fool



Elon Musk wants you to cut the cord to the cable. He is trying to raise $ 500 million for his SpaceX rocket company to low-ball form with up to 12,000 satellites to provide high-speed internet service – and he wants the first set of them in circulation by mid-year. [19659002] It may seem like an ambitious deadline, but anyone who looked at Musk push SpaceX, Tesla (NASDAQ: TSLA) or even his Boring Company ahead knows that he likes to go big. Make cheap internet available to everyone around the world, and with half of the world's traffic going through their constellation of Starlink satellites? For the man who is probably one of today's most visionary leaders, it is just another day ending in "y".

Laser-fast communication

At the beginning of last year, SpaceX launched two prototype satellites in orbit, named Tintin A and Tintin B, and installed a series of ground stations around the country to communicate with them. SpaceX plans to launch 1

,600 satellites over the next few years – the system will work when 800 satellites are in orbit – and launch the full spectrum of 12,000 satellites by 2025.

Once in a while, Starlink will receive signals from ground stations via radio waves. It will then transmit the signals between satellites with lasers; When a signal reaches the satellite over its destination, it will be radiated with radio waves again. The process will accelerate communication to a speed approximately twice as much as possible with optical fiber.

The promise of the system is that it will provide wireless connections directly to consumers rather than having signals redirected via multiple waypoints as with cable and existing satellite TV, resulting in relatively expensive service. SpaceX seems to dramatically reduce the cost of internet service for everyone.

Go Big or Go Home

However, low-speed satellites are not a perfect or risk-free solution. There is concern over the abundance of space debris in the Earth's orbit. Meanwhile, the Institute of Electrical Engineering and Electronics engineers estimate that every six years there is a 45% chance of an injury or death from a Starlink satellite crashing into the ground.

Although much of a satellite will burn up on reentry, not everyone will. Launched in a regular stream until all 11,927 are in circulation, SpaceX's satellites will start to fall out of the sky in the same way six years after launching the first part, with an average of five a day again on the atmosphere. The likelihood of any single satellite causing a mortality is extremely small, but with so many satellites reproducing the atmosphere, the risk is high.

Of course, not everything that Musk refers to does not work. Tesla only missed its fourth quarter production goal for Model 3 and lowered the price of the vehicle by $ 2000 and sent its shares tumbling. Also Boring Company recently revealed its tunnel during Los Angeles left many underwhelmed. Instead of the autonomous 16-passenger car sliding along speeds up to 150 mph promised, a specially equipped Tesla bumped along an uneven rail system at 50 mph.

Remember, however, that 247,000 Teslas delivered in 2018 almost matched The number of vehicles that Tesla delivered in all previous years combined. Furthermore, the tunnel demo was that, a prototype of what Musk thinks to travel – and the tunnel is only a mile long, so super-fine speeds are not practical. Also built for just $ 10 million, the tunnel is much cheaper than $ 200 million to $ 500 million per mile. Local authorities usually pay for the subway.

To be fair, the tunnel was built on and adjacent to the space area. A tunnel in the middle of a big city will not be as easy or cheap to build as the demo tunnel. In fact, Musk interrupted one of his test tunnels during Los Angeles due to resistance to the project – but it is still likely to be significantly cheaper than the cost of tunnels built today.

Key takeaway

Musk is looking to make human journey to Mars a reality, and revenue from his constellation of Starlink satellites would be the means of financing it. Although this massive supply of satellites circling the world shows the risk (both for earth and musk), it is quite likely that he will begin a new course that radically changes how we connect to each other via the internet. [19659002] The lone should, to a large extent, endanger cable operators who could see their businesses all the way up. It should surely be more worrying than the average person wondering if Tintin A or Tintin B will fall on their house.
