The 'Mission: Space' ride at Disney World, Florida has re-opened a day after a woman who fell ill after riding the attraction died in hospital.

The 49-year-old, who was not identified, reported nausea and dizziness after she got off the ride on Tuesday, Disney officials said. She was taken to Celebration Hospital, where she died Wednesday.

Disney told state officials she may have suffered from high blood pressure and other unspecified health problems.

It was the second death in less than a year related to the Epcot attraction, which has motion sickness bags and signs warning people with heart, back and neck problems not to ride. The popular attraction spins riders in a centrifuge that subjects them to twice the normal force of gravity, and is so intense that some riders have been taken to hospital with chest pain

The ride re-opened Thursday after engineers said that it was operating properly and they could find nothing wrong with it, declaring it was safe for the public.
