Florida. The first Vandenberg Air Force Base landing at the Space Shuttle runway occurred in December 2010. Landings occur at both Vandenberg and Cape Canaveral depending on mission requirements. On 20 December 2019, the first Starliner crew capsule was launched in Boe-OFT un-crewed test flight. The Atlas V launch vehicle performed flawlessly but an anomaly with the spacecraft left it in a wrong orbit. The orbit was too low to reach the flight's destination of ISS, and the mission was subsequently cut short. Mission success record In its 94 launches (as of July 2022), starting with its first launch in August 2002, Atlas V has achieved a 100% mission success rate and a 98.93% vehicle success rate. This is in contrast to the industry success rate of 90%–95%. The first anomalous event in the use of the Atlas V launch system occurred on 15 June 2007, when the engine in the Centaur upper stage of an Atlas V shut down early, leaving its payload – a pair of NROL-30 ocean surveillance satellites – in a lower than intended orbit. The cause of the anomaly was traced to a leaky valve, which allowed fuel to leak during the coast between the first and second burns. The resulting lack of fuel caused the second burn to terminate 4 seconds early. Replacing the valve led to a delay in the next Atlas V launch. However, the customer (the National Reconnaissance Office) categorized the mission as a success. A flight on 23 March 2016, suffered an underperformance anomaly on the first-stage burn and shut down 5 seconds early. The Centaur proceeded to boost the Orbital Cygnus payload, the heaviest on an Atlas to date, into the intended orbit by using its fuel reserves to make up for the shortfall from the first stage. This longer burn cut short a later Centaur disposal burn. An investigation of the incident revealed that this anomaly was due to a fault in the main engine mixture-ratio supply valve, which restricted the flow of fuel to the engine. The investigation and subsequent examination of the valves on upcoming missions led to a delay of the next several launches.
