I think Kessler is rather less of a concern than global climate change.

You use any of the launch providers, yes, including Arianspace.

Correctamundo. You can't speed up light. For low latency you need LEO, and since they don't sit still for you (8km/s roughly) you need a bunch of them in some kind of formation or constellation, so that you generally have something to connect to at any given moment, or at least a chain that can relay to ground stations.

I suggest you look up the solution that Telesat will use. I'm not involved in that project, but a quick glance shows me that the engineers involved have probably done their homework and have considered the customer base and their needs, including the need to service all regions of the country.

Terrestrial solutions for remote areas typically have excessive build out and maintenance costs.

Engineers will do a tradeoff and select the most suitable solution given the criteria. It's very easy to underestimate costs, particularly over the entire lifetime of the system.

Yes there are such solutions, but for remote regions without infrastructure and with high build out and operating/maintenance costs for terrestrial technology, I suspect that the most cost effective solution that we can achieve in a timely fashion is probably LEO, like Lightspeed or Starlink. Particularly since Canada has half a century of experience building satellite systems.

Managing LEO debris and congestion is not an insurmountable challenge.

Buddy, I'm an aero eng. There are lots of ways to get satellites in polar orbits.

Why didn't you look at the actual Lightspeed site from Telesat? Why would you pick a random paper? The Telesat site explains how they get coverage in polar regions.

Fibre is not going to get us up north.

Why bother paying anything? Let it go to court. Threatening annexation should fall under some kind of hostilities clause, national security clause, or force majeure clause. Anyway who's going to collect?

The US government can pay ~~MD~~ Lockheed, they're the ones who threatened annexation.

Edit... Fixed above, not sure why I had MacDonell Douglas on my mind...strange substitution for a company that no longer exists under that name.

Thank you. Fixed it.

 

Canada desperately needs a national strategic internet constellation.

Edit to fix link.

He likes the X because the ASCII code is 88, which is a number of note among neo-Nazis because it stands for HH, or Heil Hitler. I'm now convinced of this. The coincidence is too strong to overlook.

 

According to Reuters, Trump is preparing to remove legal status for 240000 Ukrainian immigrants, following which they will likely be deported back to a war zone.

The US continues her slide into global irrelevance, abandoning respect for democracy, the rule of law, and human rights.

It is the duty of the countries that continue to respect democracy and human rights, including Canada, to prevent these people from being forced back into a war torn country.

Edit Still getting the hang of this, created this post without the link to Reuters. Apologies, link added.

 

This is one sample visit to the conservative subreddit. It's an appalling example of the impact of disinformation. When you need to be reminded of who the enemy is and what they think, visit here. You will see that there is no gratitude or mutual respect, and there never was. There was never any concept of mutual benefit. And now, with Trump leading the cult, there truly is no depth to which they won't go, and no decisions from Trump that won't be retroactively justified.

These people are dangerous, and they don't give a shit about any alliances, friendship or partnership. And they control the levers of power.

Edit to add a screenshot. Not sure how to add more, but it doesn't get any better as you go deeper. What's clear is that this relationship is over, and we need to move on.

 

At the first Trump cabinet meeting, he stated his intentions clearly. He restated blatant lies and disinformation, and he won't really be questioned on it from the press or from any US politicians. The US is the enemy of Canada and should be understood as such. Take heed of his treatment of Ukraine - when he noted that they would lose the war without US help - and consider what he will propose when he uses the same argument on us. He makes it very clear in the video.

And very carefully consider which of our political leaders will stand up to Trump when he makes the argument that we need American military in our country to protect us.
