The Atlas 5 that went up was built by ULA United Launch Alliance, this one had 4 solid booster that dropped off as the rocket was going out of site. They will have to switch over to the Falcon 9 Rocket built by SpaceX with the reusable first stage that they land back near the launch pad, or land back to the floating barge out in the ocean. Reusable parts, just as well.

Very large and expensive 1st Stage that they are able to Recycle and Reuse multiple times
