Fifty years after Moon mission, Apollo astronauts meet at historic launchpad
Fifty years ago on Tuesday, three American astronauts set off from Florida for the Moon on a mission that would change the way we see humanity's place in the universe.
The crew's surviving members, Buzz Aldrin and Michael Collins, are set to reunite at the same launchpad on Tuesday, the start of a week-long series of events commemorating Apollo 11.
Their commander and the first man on the Moon, Neil Armstrong, passed away in 2012.
But Aldrin and Collins, 89 and 88 respectively, will meet Tuesday at precisely 9:32 am (1332 GMT) at the Kennedy Space Center's pad 39A to kick off the festivities.
At 82, NASA pioneer Sue Finley still reaching for the stars
Sue Finley began work at the Jet Propulsion Laboratory as the US prepared to launch its first satellite into orbit in 1958, racing to match the Soviet Union, which had accomplished the feat months earlier.
Now 82, she is one of NASA's longest-serving women, starting out as one of its "human computers," whose critical yet long-hidden contributions to the space program, including the Apollo missions to the Moon, are finally being recognized.
Finley had dropped out of college and joined a group of mathematically gifted individuals, overwhelmingly women, whose job it was to solve the complex equations thrown at them by rocket scientists before electronic computing became affordable and reliable.
Fireflies’ glow could soon be extinguished by human actions
Species’ extinction rates are accelerating on a global scale. We need solutions that match the severity of the problem.
Say goodbye to one of the dreamiest things about childhood. In the Midwest, fireflies are dying off.
For many Americans, it’s hard to imagine summer nights without the magical glow of dozens of bioluminescent bodies fluttering above the grasses and fields, and lighting up the dark skies above.
