United Launch Alliance chief executive Tory Bruno said Thursday the company will offer more rides for CubeSats aboard future Atlas 5 rocket flights, and give some away for free, in a bid to tap into a growing market of small satellites with applications in education, scientific research and commercial business.

The bronze first stage of United Launch Alliance’s next Atlas 5 rocket arrived at its Cape Canaveral launch pad Friday, where it will be joined by five solid-fueled boosters, a Centaur upper stage and a U.S. Air Force communications satellite in the coming weeks ahead of liftoff set for June 27.

United Launch Alliance said Monday it did not submit a proposal in a competition to launch a U.S. Air Force GPS navigation satellite, apparently relinquishing the contract to rival SpaceX, the only other company certified to launch the mission.
