Destiny is finally here.
The research cornerstone for the International Space Station is set to be delivered on Wednesday. A permanent orbiting science lab will greatly reduce the costs of conducting experiments. A miniature version of the pump that powers the Space Shuttle's engines is now regulating blood flow in human hearts. Instruments to measure bone loss and bone density in astronauts without penetrating the skin are now being used in hospitals. The Destiny lab will not be operational until about a month after delivery.
