Cosmic Spotlight
Isar Aerospace’s fresh capital arrives as Europe tries to build a more competitive launch sector. The 270 million euros will fund both the next Spectrum test flight and factory expansion needed for higher cadence. Success here would give the continent a second medium-lift option alongside ArianeGroup vehicles. Failure would reinforce how difficult it remains for new entrants to reach reliable operations. Will the company’s first orbital attempt later this year deliver the performance needed to attract follow-on government contracts?
Cosmic Deep Dive: How Mega-Constellations Keep Satellites from Colliding
If every Starlink satellite were the size of a city bus, the entire constellation would still fit inside a volume smaller than Earth’s atmosphere. Each spacecraft flies in a carefully chosen orbital shell where slight differences in altitude and inclination create natural separation. Operators fire tiny thrusters only when ground tracking predicts a close approach measured in kilometers, not meters. A single shell at 550 km altitude can hold thousands of satellites because they move at 7.6 km per second and pass one another in fractions of a second. Yet the real puzzle is how the system scales: adding another ten thousand satellites requires predicting conjunctions years in advance while accounting for solar activity that changes atmospheric drag. No one yet knows the practical limit before collision risk or radio interference forces operators to thin the shells or move to higher orbits.
Another day of steady progress across commercial launch, Earth observation, and mission planning. |
