Happy Earth Day!
What better way to commemorate the day than by taking a good look at the planet we have a chance to save?
NASA is celebrating the 40th anniversary of the Apollo 8 Earthrise photograph (right), credited with inspiring the beginning of the environmental movement in the late 1960s and ’70s.
From 6 a.m. to 8 p.m. EDT today, the agency will air high-definition views of the planet captured by astronauts on past space-shuttle and space-station missions. The footage will be broadcast on standard NASA TV.
In addition, the NASA website will feature several new items, including the 10 most outstanding Earth views taken by astronauts aboard the space station.
You’ll also find a breathtaking series of nighttime images of city lights captured by astronaut Don Pettit, who lived aboard the space station in 2003. He narrates the imagery, which he gathered using a special mechanism he developed to steady the camera and track cities as the space station flew overhead at 5 miles per second.
