Starlink - Space X's space internet project

We haven't focussed much on the Starlink project, which ultimately will involve a 12,000 satellite space internet project...

Things seem to be going well:

https://www.space.com/39785-spacex-inte … ation.html

It's an interesting topic in relation to Mars.  Firstly, because previous projections from Space X have suggested this is supposed to generate a huge revenue stream. I can see how that might be, especially if it undercuts existing ISP charges. If it does, it could easily pay for infrastructure investment on Mars over the next few decades. Secondly, I am wondering if it would have any use in communication with Mars. Would it mean you could beam radio message toward Earth and the Starlink network could pick it up?

Any thought on Starlink?

Re: Starlink - Space X's space internet project

First Space x is a launch provider and not a satelite manufacturer but that said I sure would like a cheap internet.

Here’s everything you need to know about SpaceX Starlink

Between sexy electric cars, “hyperloop” transit systems, reusable rockets, and Mars colonies; there’s certainly no shortage of things to look forward to from the guy. The project is expected to cost around $10 billion in total. There are currently only 1,459 satellites currently in orbit around earth, along with 2,600 inactive. SpaceX will need to launch 4,425 satellites into orbit to achieve its desired coverage. On February 22, 2018, SpaceX and Starlink took a huge step: The project successfully launched the first two Starlink test satellites (named Tintin A and Tintin B) from the Vandenberg Air Force base in California.

SpaceX’s Starlink Satellite Internet: 5 Fast Facts You Need to Know

SpaceX's plan to beam down internet from space comes with a big debris problem

ouch traffic jam....

The derelict Russian satellite Cosmos 2251 had been aimlessly spinning around Earth for nearly 15 years when, in 2009, it slammed into a functional Iridium telecommunication satellite at 26,000 miles per hour.

This collision sprayed an estimated 200,000 centimeter-sized bits of debris into orbit around Earth. Another 3,200 broken pieces from the crash were much larger, at 10 centimeters or greater in size.

Not every nation deems that they should send the satelites and other space items into the oceans of the world before it is to late to do so.

Sure we could collect and do so but at what cost and technology?

Re: Starlink - Space X's space internet project

If your costs are low enough, you can launch into very low orbits that are cleared of debris byatmospheric drag, and just replace satellites whenever they run out of propellant and fall out of the sky.

Re: Starlink - Space X's space internet project

Re Spacenut's comments, although Space X won't be manufacturing the satellites, it does look like it is their project - so they are buying them in I presume.

Re: Starlink - Space X's space internet project

SpaceX's 60-Satellite Launch Is Just the Beginning for Starlink Megaconstellation Project

May 23, 2019 · On Thursday night, SpaceX launched a batch of 60 internet communications satellites from Cape Canaveral Air Force Station in Florida. More than one hour later, some 270 miles above Earth, the cluster of satellites — part of a system called Starlink — pushed off from the rocket that carried it to orbit.

SpaceX won regulatory approval to launch nearly 12,000 Starlink broadband relay stations in multiple orbital planes. Equipped with high-speed satellite-to-satellite communications links, the eventual network is designed to seamlessly hand off internet traffic as required to provide uninterrupted access.

Re: Starlink - Space X's space internet project

I am watching the "Hysterical Manic/Depressive" news about this.

Astronomers are upset about light pollution.

And there is some hysteria about the Kessler Syndrome potential.

I think that SpaceX has already proposed to pigment their future editions, to reduce the astronomical concerns.

As for the Kessler Syndrome, I have to imagine that for SpaceX to have gotten permission to do Starlink, the powers that be, are satisfied that a run-away Kessler Syndrome can be avoided, if proper concern is applied.

I also feel that since I have seen mention of a Starship type that can clean space junk, and also other entities such as the ESA, are also looking into cleaning methods which could involve harpoons, that in the future, who makes the junk will be responsible to clean it up.  Not a guarantee, (I would be very disappointed by a Kessler Syndrome actually happening), but any tool we use can have bad effects if badly used.

……

But back to Astronomy....

I have wondered if something like these Starlink devices could possibly be used to do some Astronomy.

So far, I have two things in mind.

1) I seem to recall that Japan, had an incident where an asteroid occulted a star, and in this event, it was possible to extract information about the star.  So, could a device similar to a Starlink satellite be able to be maneuvered in such a way as to occult a star, in hopes of doing the same I would presume that ground based telescopes would be the seeing devices.  Of course size, distance, and position would need to be set correctly, and the event would be very quick.  However, the device might be able to be used many times for many stars.  For this version of the device, I should think that it would be desired to give the device extra propellant, and to make it have a long functioning life time.

2) The other thing would be a ring of these devices around the Moon.  Some orbits of the Moon are relatively stable, I understand, but many are not.  However these devices would have active propulsion, and so could fight to stay in an aligned orbit while they were functioning.  I am imagining that some part of the ring would be on the far side of the Moon during parts of their orbits.  And yet I would expect that the entire ring could communicate with itself, so information appropriated by the devices could be extracted from the devices which were currently on the near side.  Another method would be that the far side devices record some information, and then transmit it to Earth when they passed to the near side of the Moon.

The instrumentation for this is quite a bit beyond my comprehension, but even though this would not necessarily be as good as a radio telescope, perhaps there is something of importance that could be discovered by such a device.  It also obviously does not require landing on the Moon, and setting up on the Moon's surface.

And of course such a ring around the Moon could also facilitate communications with activities of machines and crews operating on the far side of the Moon.

Anyway, why not at least consider the notions?

Done.

I like people who criticize angels dancing on a pinhead.  I also like it when angels dance on my pinhead.

I see to many topics and stuff not of the topic as always....

Here is the next up and coming event.

Re: Starlink - Space X's space internet project

Aka "fairing"?? Or is that something different...?

Re: Starlink - Space X's space internet project

A fairing is the shroud or cover that surrounds the payload or cargo which will be launched for use. Generally, the cargo is a satellite although any other .

SpaceX faces competitors in race to build Internet-satellite constellation On Monday, SpaceX's Falcon 9 rocket is scheduled to deliver 60 small satellites into orbit.

The new batch of satellites will bring the Starlink constellation population to 120. As part of its satellite Internet operation, SpaceX plans to launch some 12,000 satellites over the next half-decade.

Thats a huge number of satelites.... and its only going to get more crowded wity more competition on the way. Richard Branson's Virgin Group, Boeing, Amazon and LeoSat Enterprises


Last winter, OneWeb launched six small satellites. Tests confirmed the mini constellation produces a serviceable signal, and the company expects to launch another 60 satellites in early 2020.

Thats definently going to competition and hopefully that means low cost
OneWeb, which is targeting an initial constellation population of 650, and later 2,000, expects to begin offering service in the Arctic by the end of 2020 and global coverage in 2021.

Re: Starlink - Space X's space internet project

Why is American internet access so much more expensive than the rest of the world?

The same question could be asked of the cable TV costs since many reside on the same wire....
