Alternate mission URLs consolidate to this canonical launch record so exact mission timing, status, media, and source context stay on one page.
Use these internal paths to move from this exact launch record into the provider, vehicle, launch-site, schedule, and mission-family pages that own broader context.
This launch currently has no dedicated mission-family hub, so provider, vehicle, site, and canonical record links are the primary internal paths.
Some high-demand launch records carry specialized search intent. These profiles explain what can be verified from the published record without filling gaps that upstream sources have not published.
Published fields only: this page surfaces provider, vehicle, pad, timing, status, source links, and public mission metadata. Payload details may be limited when public sources do not publish them.
Key structured fields for this launch record are grouped here so the page answers mission, payload, orbit, provider, source, and timing questions before the deeper tracking and media sections.
This record is preserved as historical launch context. The page emphasizes what was launched, the vehicle and pad involved, published outcome/status fields, linked programs, and source records instead of treating the mission like an upcoming countdown.

Atlas V is an expendable launch system in the Atlas rocket family. It was formerly operated by Lockheed Martin and is now operated by United Launch Alliance (ULA), a joint venture with Boeing. Each Atlas V rocket uses a Russian-built RD-180 engine burning kerosene and liquid oxygen to power its first stage and an American-built RL10 engine burning liquid hydrogen and liquid oxygen to power its Centaur upper stage. The RD-180 engines are provided by RD Amross, while Aerojet Rocketdyne provides both the RL10 engines and the strap-on boosters used in some configurations. The standard payload fairing sizes are 4 or 5 meters in diameter and of various lengths. Fairings sizes as large as 7.2 m in diameter and up to 32.3 m in length have been considered. The rocket is assembled in Decatur, Alabama and Harlingen, Texas.
United Launch Alliance (ULA) is a joint venture of Lockheed Martin Space Systems and Boeing Defense, Space & Security. ULA was formed in December 2006 by combining the teams at these companies which provide spacecraft launch services to the government of the United States. ULA launches from both coasts of the US. They launch their Atlas V vehicle from LC-41 in Cape Canaveral and LC-3E at Vandeberg. Their Delta IV launches from LC-37 at Cape Canaveral and LC-6 at Vandenberg.
