caption_attribution_description: English: CAPE CANAVERAL, Fla. -- At Kennedy Space Center's Launch Pad 39A, center director Bob Cabana announces that NASA has just signed a lease agreement with Space Exploration Technologies SpaceX of Hawthorne, Calif., for use and operation of Launch Complex 39A. NASA Administrator Charlie Bolden, left, and Gwynne Shotwell, president and chief operating officer of SpaceX, look on. SpaceX will use Launch Complex 39A for rockets such as the Falcon Heavy, currently under development. Both launch pad 39A and 39B were originally built for the Apollo/Saturn V rockets that launched American astronauts on their historic journeys to the moon and later modified to support the 30-year shuttle program. Pad 39B is now being modified by NASA to support the Space Launch System SLS rocket boosting the Orion spacecraft part of the agency’s plan to explore beyond low-Earth orbit.
context_page_description: Launch Complex 39 is a rocket launch site at the John F. Kennedy Space Center on Merritt Island in Florida, United States. The site and its collection of facilities were originally built as the Apollo program's "Moonport" and later modified for the Space Shuttle program.
  Launch Complex 39 consists of three launch sub-complexes or "pads"—39A, 39B, and 39C—a Vehicle Assembly Building, a Crawlerway used by crawler-transporters to carry mobile launcher platforms between the VAB and the pads, Orbiter Processing Facility buildings, a Launch Control Center which contains the firing rooms, a news facility famous for the iconic countdown clock seen in television coverage and photos, and various logistical and operational support buildings.
  SpaceX leases Launch Complex 39A from NASA and has modified the pad to support Falcon 9 and Falcon Heavy launches.NASA began modifying Launch Complex 39B in 2007 to accommodate the now defunct Constellation program, and is currently preparing it for the Artemis program, whose first launch is scheduled for no earlier than 2021. A pad to be designated 39C, which would have been a copy of pads 39A and 39B, was originally planned for Apollo but never built.
context_section_description: By early 2013, NASA publicly announced that it would allow commercial launch providers to lease LC-39A, and followed that, in May 2013, with a formal solicitation for proposals for commercial use of the pad.
  There were two competing bids for the commercial use of the launch complex. SpaceX submitted a bid for exclusive use of the launch complex, while Jeff Bezos' Blue Origin submitted a bid for shared non-exclusive use of the complex, so that the launchpad would handle multiple vehicles, and costs could be shared over the long-term. One potential shared user in the Blue Origin plan was United Launch Alliance. Prior to the end of the bid period, and prior to any public announcement by NASA of the results of the process, Blue Origin filed a protest with the U.S. General Accounting Office (GAO) "over what it says is a plan by NASA to award an exclusive commercial lease to SpaceX for use of mothballed space shuttle launch pad 39A." NASA had planned to complete the bid award and have the pad transferred by October 1, 2013, but the protest "will delay any decision until the GAO reaches a decision, expected by mid-December." On December 12, 2013, the GAO denied the protest and sided with NASA, which argued that the solicitation contained no preference on the use of the facility as multi-use or single-use. "The [solicitation] document merely asks bidders to explain their reasons for selecting one approach instead of the other and how they would manage the facility."
  On April 14, 2014, the privately owned launch service provider SpaceX signed a 20-year lease for Launch Complex 39A (LC-39A). The pad was modified to support launches of both Falcon 9 and Falcon Heavy launch vehicles, modifications that included the construction of a large Horizontal Integration Facility (HIF) similar to that used at existing SpaceX-leased facilities at Cape Canaveral Air Force Station and Vandenberg Air Force Base, horizontal integration being markedly difference from the vertical integration process used to assemble NASA's Apollo and Space Shuttle vehicles at the launch complex. Additionally, new instrumentation and control systems were installed, and substantial new plumbing was added for a variety of rocket liquids and gases.
