Spirits arrived at the International Space Station on Monday. Not the ghostly ones, but the kind you drink — distilled spirits.

A Japanese company known for its whiskey and other alcoholic beverages included five types of distilled spirits in a space station cargo ship. The station’s big robotic arm — operated by Japanese astronaut Kimiya Yui — grabbed onto the supply craft launched Wednesday by his homeland. Flight controllers helped anchor it down.

The supply ship contains nearly 10,000 pounds of cargo, including the six liquor samples. Suntory Global Innovation Center in Tokyo wants to see if alcoholic beverages mellow the same in space as they do on Earth.

The samples will spend at least a year in orbit before being returned to Earth. An identical set of samples will be stored on the ground in Japan.
