An anonymous reader writes: A building at NASA's Kennedy Space Center in Florida, where Apollo astronauts once trained, was named in honor of astronaut Neil Armstrong. Armstrong, who died in 2012, was remembered at a ceremony as not only an astronaut, but also as an aerospace engineer, test pilot, and university professor. NASA renamed the Operations and Checkout building, also known as the O&C, which is on the National Register of Historic Places. It has been the last stop for astronauts before their flights since 1965. It was also used to test and process Apollo spacecraft. Currently, it's where the Orion spacecraft is being assembled to send astronauts to an asteroid and later to Mars.
