International Space Station Celebrates 15th Birthday
Astronauts have circled the Earth on board the International Space Station for 15 years on Monday, a milestone for an orbiting space lab that some say deserves to win the Nobel Peace Prize.
With operations expected to last another decade, the world’s space agencies are now looking to the outpost to provide key data on how future space pioneers may withstand the rigors of venturing further, perhaps even to Mars.
“We do a lot of experiments up here but I think the most important experiment is the space station as an orbiting vehicle that keeps humans alive in space for long periods of time,” said Nasa astronaut Scott Kelly, during a live press conference with the station’s crew to mark 15 years of continuous habitation.
