    Good luck to them all. We still don’t have a small rocket that is able to do rapid launch cadence in any meaningful sense, so there’s room for new entrants. Although Relativitys $12M a pop isn’t going to be sustainable
    And for PLD, its way past due for Europe to diversify their industry a bit

    • duheagle says:

      Relativity isn’t depending on the sustainability of Terran-1, though as a higher-end expendable smallsat launcher, it stacks up passably well against its Firefly Alpha and ABL RS-1 competition. Development of the much larger, and completely reusable, Terran-R is already well underway.
