On Sunday, May 16, 10 children will celebrate Father's Day on Earth while their fathers orbit overhead as members of the Expedition 36 crew aboard the International Space Station.

The crew has numerous ways to stay connected with family: email updated daily by Mission Control, use of a special phone to call when they have free time and video conferences, usually planned for the weekends when work is light.
