”…the Brazil price of $35.6 million indicates even lower prices in the future.”

The fact that the Amazonia launch is only 40% of the price of the Pleiades launch suggests that it’s a rideshare and that the $35 million doesn’t cover the full cost of the launch. That the Amazonia 1 satellite weighs only 1,400 lbs, which is just 30% of the launch capacity of the Vega-C, also suggests this.

The full price of $85 million to launch about 5,000 lbs to LEO is not that great. It’s a bit more capacity than a Minotaur IV for about twice the price.

”A decade ago launches never cost less than $100 million.”

This is just flat-out false. A decade ago you could get a Pegasus, Taurus, Minotaur I, Minotaur IV, Antares, or a Delta II launch for less than that. The list price of a Pegasus today is $42 million, and a Minotaur goes for $35-50 million. For $85 million you could get an Antares launch with 3-1/2 times the capacity of a Vega-C launch until Russia bombed the first stage factory in Ukraine in 2022.

Even back in the early 90s you could get a Delta II launch for $55 million, which translates into about $90 million today — and that was for a vehicle with twice the payload capacity and a far better launch record than the Vega-C.

The Vega launch vehicle family, like the Ariane family, exists to give Europe “autonomy” in space, not because it is less expensive (or even profitable). This also applies to customers like the Brazilian government who don’t want to fly American.
