TWO Nasa astronauts safely back on Earth after an unexpected nine-month stint on the International Space Station face an arduous road to recovery.

Butch Wilmore, 62, and Suni Williams, 59, were taken from their capsule for urgent medical evaluation following their 17-hour journey.

The pair now face weeks of grappling with the punishing effects of prolonged weightlessness.

Senior Nasa administrator Joel Montalbano described the landing as "beautiful" and said their 150 experiments and 900 hours of research will inform future moon missions.
