This helps explain the merger between the two companies, as it gives Orbital control over the equipment it needs to keep Antares viable. More important, it also could make it entirely American made, which will be attractive to both Congress and many U.S. commercial satellite companies.

    That will cost them some clients.

    And you don’t use some solid rocket motors to replace liquid ones. It would require a pretty complete redesign of the bulk of the booster (not just the first stage).
