On Sunday, an X-37B space plane formed by the U.S. Armed Forces touched based at Kennedy's Space Center in Florida. According to the American Air Force, it just finished a mission that lasted for 48 months, classified to the general population. At approximately 7:47 a.m. Eastern Standard Time (1147 GMT), the unmanned spacecraft landed on a runway the center previously utilized to station retired air crafts. In an email provided by the U.S. Air Force, it says that the plane, originally assembled by Boeing, initially launched in May 2015 near their station in Cape Canaveral.

The spacecraft propelled from off an Atlas 5 rocket manufactured by United Launch Alliance. The ULA is an organized partnership formed between the Boeing and Lockheed Martin Corporations.

Latest details

The stunning aircraft that landed this week is only one of the two X-37Bs in the armada of the U.S. Air Force. While it operated in orbit for over two years, the plane orchestrated several experiments that remain undisclosed by the American military. The mission is the fourth and longest enigmatic program currently overseen by the Air Force Rapid Capabilities Office thus far.

The Air Force stated upon landing that they conducted the mission to perform risk assessments and experiment with reusing advanced space technologies and aeronautical developments.

The military branch provided statements to the press without giving any purposes of intrigue. Information on the overall cost of the program is also deemed confidential.

A non-profit organization that encourages all tranquil space exhibitions spoke on behalf of the Air Force’s latest project shortly after the iconic landing of the X-37B.

The Secure World Foundation asserted that the mystery encompassing the X-37B seems to reveal the military’s attempts to survey and test artificial intelligence operating within the aircraft.

The phenomenal space transporter is about 29 feet (9 meters) long. It has a wingspan of approximately 15 feet. The size of this carrier is massive.

However, it’s still only one-fourth the size of all the retired space crafts currently on display from the National Aeronautics and Space Administration.

Historical data

Aeronautical scientists throughout the United States often refer to the X-37B as an Orbital Test Vehicle. April 2010 is when this OTV took first took flight. It returned eight months later. The U.S. military launched a second mission with the aircraft in March 2011 that lasted for more than a year. A third project utilizing the space plane took place in December 2012. The mission took 22 months to complete.

The arrival of the U.S. military's X-37B space plane on Sunday was the first time the OTV landed in Florida. After the three previous military projects launched during their respected times, the aircraft always landed at California's Vandenberg Air Force Base.

The Air Force migrated the projects in 2014 after taking over two of NASA's previous transport handling storages.

The Air Force stated during a press conference that it expects to dispatch its fifth experiment with an X-37B from the Air Force Base in Cape Canaveral a few months from now.
