This is what Microsoft AI has to say:

Launching from the equator requires significantly less fuel than launching from the Arctic because the equator provides up to 465 m/s of free rotational velocity, while the Arctic provides almost none, increasing the rocket's required delta‑v and therefore its propellant load.

🌍 Why latitude changes fuel needs
Earth rotates eastward, and that rotation gives rockets a "free" horizontal velocity when they launch eastward.

• At the equator, the surface moves at ~465 m/s eastward.
• At high latitudes, the rotational speed decreases with cos (latitude) and becomes 0 m/s at the poles.
• This inherited velocity directly reduces the delta‑v the rocket must supply to reach orbit.

Since delta‑v determines propellant mass through the Tsiolkovsky rocket equation, even a few hundred m/s difference has a large impact on fuel requirements.

📉 How much fuel difference does this create?
The equatorial boost of 465 m/s is a meaningful fraction of the ~9.4–10 km/s total delta‑v needed to reach low Earth orbit (including gravity and drag losses)

Examples from the results:

• Launches from mid‑latitude sites like Florida (28.5°N) get only ~409 m/s of rotational boost.
• Launches from the Arctic (≈70–90°N) get near zero boost.
• Launches to equatorial orbits from non‑equatorial sites require costly inclination‑change maneuvers, which can consume 1–2 km/s of delta‑v.

A 1–2 km/s plane‑change penalty is enormous: it can reduce payload by 20–80% depending on the rocket and orbit.

📦 Payload and fuel consequences
Because less delta‑v is required at the equator:

• More payload can be carried for the same fuel load.
• Or less fuel is needed for the same payload.
• For geostationary missions, equatorial launches can reduce propellant needs by 10–20%.

Conversely, launching from the Arctic:

• Requires more propellant to reach the same orbit.
• May require large plane‑change burns to reach low‑inclination or equatorial orbits.
• Can reduce payload capacity dramatically (up to 80% for equatorial orbits from Cape Canaveral, and worse from the Arctic).

🔢 Quantitative comparison (conceptual)

Launch Site	Rotational Boost	Extra Delta‑v Needed vs Equator	Fuel/Payload Impact
Equator (0°)	465 m/s	Baseline	Lowest fuel, highest payload
Florida (28.5°N)	~409 m/s	+56 m/s	Small fuel penalty
Arctic (≈80°N)	~80 m/s	+385 m/s	Large fuel penalty; major payload loss
Pole (90°N)	0 m/s	+465 m/s	Maximum fuel penalty

Because delta‑v enters the rocket equation exponentially, a 465 m/s penalty can require tens of percent more propellant or reduce payload by similar margins.

🛰 Why equatorial launches dominate GEO missions
Geostationary orbit lies directly above the equator. Launching from the equator:

• Avoids expensive inclination‑change burns.
• Minimizes delta‑v.
• Reduces propellant needs by 10–15% for GEO transfers.

Launching from the Arctic would require a full plane change, costing 1–2 km/s of delta‑v—often more fuel than the entire upper stage carries.

✅ Bottom line
Launching from the equator saves fuel because:

• You inherit up to 465 m/s of free velocity.
• You avoid costly inclination changes for equatorial orbits.
• The rocket equation amplifies these savings into major reductions in propellant mass and major increases in payload capacity.

Launching from the Arctic removes all these advantages and can require tens of percent more fuel or reduce payload by 20–80%, depending on the mission.

We'd most likely make a space center on the Laurentian Shield. Possibly another as high in the Arctic as possible. Naturally we'll be looking at ways of decreasing the fuel requirements of future rockets.

The Earth's atmosphere is approximately 18 to 20 km deep at the equator, versus 6 to 8 km deep at the North Pole. There might be ways of taking advantage of that.

As technological science progresses, hopefully new techniques such as antigravity or folding space come into play.

Where would they launch from? The best launch sites are near the equator. The further from the equator you get, the more fuel it takes to get into orbit. The exception is flights to polar orbits, which can be launched from anywhere.

Would Canadian rockets launch from the European Space Center in French Guiana? That would be optimal. Would they launch from Florida? Somehow, I don't think Canadians would like that. Launches from Canadian soil would have much higher fuel requirements and wouldn't be competitive.

Winnipeg to host North American Indigenous Games for 1st time since 2002

The North American Indigenous Games are scheduled to return to Winnipeg for the first time in over 25 years, as Norway House Cree Nation and the Southern Chiefs' Organization have been selected to host the event in 2028.

More than 5,000 athletes, coaches and team officials from more than 750 First Nations across the continent are expected to travel to Winnipeg for the competitions, a Thursday news release from the event's governing council said.

The 2028 games are scheduled to run in Winnipeg from July 9 to 23. They've only been held in Manitoba once, when they were hosted in Winnipeg in 2002.

Canada can't launch rockets on its own. A handful of companies want to change that

As the only G7 nation without its own launch capabilities, Canada is eager to have a Canadian-made rocket.

A handful of Canadian companies are racing to give the country its own way to space as quickly as possible — at the same time that some SpaceX customers worry the industry giant could soon give fewer rides into orbit.

But the rocket companies are working to complete an expensive task under a tight deadline and ever-changing government priorities, making the journey to space anything but simple.

This would be a priority under the Canadian Economic Party.

I'm starting to believe what Jotunn said about Don just throwing up his hands and just tired of the whole thing.

Just to be clear, I haven't said I think he's done that. What I have said is that no one could blame him if he made that choice. Operating Stormfront has undoubtedly been an often thankless task.

Canada's spy agency shakes up hiring process to 'meet operational needs': documents

The Canadian Security Intelligence Service is shaking up its hiring process to meet operational needs, internal emails show — a signal the service continues to face recruitment issues.

CSIS brought in a suite of changes earlier this year to "meet operational needs and emerging demands," according to documents obtained by CBC News through an access to information request.

"These changes represent a shift in how we recruit, classify, deploy and empower our people," reads one of a series of emails sent to managers at CSIS.

France welcomed invaders and the chickens are coming home to roost.


 

France is on fire primarily due to the lack of assimilation of migrants and asylum seekers from the Middle East, North Africa, Afghanistan, Pakistan, and parts of sub-Saharan Africa.

They are poorly educated, lack skills, hate Westerners, and are predominantly Marxist Islamists. The massive influx has diluted services, and education has suffered. Allowing an invasion does that.

The current riots are over poor education.

President Macron paid little attention to the riots over inferior schools until recently. The Army is now moving in to quell the riots. They have escalated, and innocent people are dying.

Details and videos in the following link.  Pay note to the video of the African 'Mayor' of St. Denis encouraging the rioters:

Violent sex offender expected to live in Winnipeg a high risk to reoffend: police

Michael Curtis Thomas, 33

A convicted sex offender with a lengthy criminal record is expected to live in Winnipeg following his release from prison and is considered a high risk to reoffend in a violent manner against women, police say.

Michael Curtis Thomas, 33, was released on a statutory release Thursday from Stony Mountain Institution in Manitoba, after he was convicted in December 2021 of aggravated sexual assault and given a 61-month sentence, in addition to credit for his pre-sentence custody, police said in a news release.

Thomas was convicted of attacking and sexually assaulting a woman in September 2020. When she tried to run away, he caught her, dragged her and choked her unconscious before sexually assaulting her again, which was interrupted by a homeowner who witnessed the incident, police said.
