🇨🇦 Mark Carney says a Canadian-built satellite network expected to launch next year will rival SpaceX’s Starlink. Meanwhile … Elon already has 10,000 satellites in orbit, owns the cheapest launch rockets also. But the socialist govt of Mark Carney thinks they will compete.

🇵🇰🚀 Pakistan Completes EO-3 Launch, Accelerating Its Satellite Constellation Drive Pakistan has successfully placed its PRSC EO-3 Earth Observation Satellite into orbit, marking a significant step in the country’s expanding space programme. The satellite, developed domestically by SUPARCO, was launched from China’s Taiyuan Satellite Launch Center, underscoring a model of local manufacturing supported by external launch capability. EO-3 completes a three satellite Earth Observation series: ◽EO-1 (2025) ◽EO-2 (February 2026) ◽EO-3 (latest launch) Together, they form the backbone of a planned integrated Earth Observation system aimed at improving data availability and coverage. Pakistan now operates 5+ Earth observation satellites, with most deployed in the last two years, highlighting a noticeable acceleration in activity. Officials describe the programme as part of a broader shift: 📡 From isolated missions → to a coordinated satellite network From external reliance → to increasing data independence 🚀 From slow launches → to a structured rollout strategy The EO-3 mission also reflects continued technical cooperation with China, particularly in launch services. With additional satellites expected in the coming years, Pakistan appears to be moving toward a multi satellite constellation designed for regular, wide area monitoring. The direction is clear: a steady build up rather than a one off achievement.

SpaceX has introduced a new website for its next-generation Starlink V3 satellites, along with new information about the satellite. • 1 Tbps downlink capacity (~10× higher than Starlink V2). • 160 Gbps uplink capacity (~22× higher than Starlink V2). • 2,048 downlink beams + 2,048 uplink beams (vs. 192 downlink/144 uplink beams on V2). • Upgraded phased array antennas enable the increased user capacity and beam count. • New SpaceX-designed beamformer chips power the phased arrays. • Modem chips handle ~64× more throughput per chip, allowing more efficient simultaneous service and real-time beam allocation based on demand. • Each satellite includes 6 high-capacity 400 Gbps laser links, enabling a redundant petabit-scale laser mesh network for global routing. • Each satellite also has 4 quad-band RF backhaul antennas operating across Ka, E, V, and W bands. • RF backhaul capacity increases to 1.2 Tbps (>8× Starlink V2). • Backhaul uplink supports 60 GHz of spectrum across frequencies and polarizations (4.3× more than V2). • New solar arrays generate ~2× the power of the V2 satellite arrays. • Solar arrays are manufactured using a continuous roll of solar blanket, cut into 19-meter sections, with 4 sections stitched together per array. • Solar arrays are optimized to reduce atmospheric drag in low Earth orbit. • A Starship launch carrying V3 satellites will deploy ~20× more network capacity than a Falcon 9 launch carrying V2 satellites. • V3 technology will support future Starlink Mobile Gen 2 satellites, delivering terrestrial-like LTE speeds directly to unmodified smartphones.
