A Northrop Grumman Cygnus supply ship arrived at the International Space Station on Monday with more than 8,000 pounds of cargo, including new astronaut sleeping quarters, parts for the station’s toilet, and numerous biomedical and technology experiments.

A SpaceX Falcon 9 rocket carrying a Dragon cargo ship loaded with more than 4,000 pounds of supplies and equipment bound for the International Space Station — including a critical docking adapter needed by future U.S. crew ships — broke apart in a shower of debris shortly after launch Sunday.

NASA has placed an order with Boeing for the first operational mission to ferry a crew to the International Space Station in a new era of commercial human spaceflight.
