Capitalism in space: ArianeGroup today successfully tested the solid rocket booster that it will use on both its Ariane 6 and Vega-C rockets in the 2020s.

The test success is good news for ArianeGroup, but this quote is actually more significant:

A compromise reached in May by European Space Agency members funding launch vehicle development will keep production of the P120C in Italy, allowing Avio to produce up to 35 boosters annually. A previous arrangement would have split production between Colleferro, Italy-based Avio and MT Aerospace of Augsburg, Germany.

The economies of scale provided by using the same booster for two rockets and concentrating production in one place are a key aspect of reducing the price for Ariane 6 missions by 40 to 50 percent compared to the Ariane 5 in use today.

Faced with stiff competition from SpaceX, the European Space Agency (ESA) gave ArianeGroup the power to structure operations more efficiently rather than cater to the pork desires of the agency’s many member nations.

Whether either Ariane 6 or Vega-C can compete with SpaceX’s reusuable rockets however remains doubtful. I expect that almost all of ArianeGroup’s customers in the next decade will be ESA member nations, required to buy its more expensive services.

    Pretty amazing that they hope to cut the price by 40-50%.

    Shows how much pork costs ….not that I should boast since I live in the Garden State…

    TRENTON, N.J. — At $2 million a mile, New Jersey spends eight times the national average on its state-controlled highways, a heavy toll that is driving the tax-supported roadway fund dry and forcing officials to rethink how roads are built.”

    I should hope so – not that I expect any results. The answer will be, “Tax the rich!” (which will mean anyone who has an income). NJ has reached The Thatcher Point. “Eventually you run out of other peoples’ money to give away”

    “triple the roughly $675,000 spent by the next-highest state, Massachusetts, and more than eight times the national average of $162,200”

    Can somebody give me a net-cost per mile, for the “super-train” in California?

    Ref: Highway construction:
    It’s worse than Col Beausabre reports. (although I don’t know where the “$2 million/mile” figure comes from,)

    I’m in Michigan and we rank 13th for ‘cost-per-lane-mile’ at $42K –so a standard divided highway (2 lanes each way, 4 total) in Michigan would come in at $168K/mile, but that also doesn’t include land, engineering, or any over-passes or exits.
    [Arizona btw is ranked 12]

    Comprehensive charts (and a lengthy PDF Report) are at:


    –For highways, you have construction cost + right-of-way-acquisition cost + engineering cost + required over-passes & Exits.
