Genesis launched in 2001 to study the sun. The spacecraft include a sample-return capsule that was shaped a bit like a flying saucer. The capsule crash-landed back on Earth in 2004 when its parachutes failed to open. 

"The Genesis mission had been orbiting the Sun collecting solar wind particles that are usually deflected away by Earth's magnetic field," says NASA, noting that some of the samples were still in good condition despite the hard landing.
