Opening Notes

Photo of half of Earth taken from outer space

This image from NASA's archives shows Earth in April 1970, just as the United States was getting ready to celebrate the first Earth Day.

A high-resolution Hasselblad camera image, it was taken during the ill-fated Apollo 13 lunar mission. The flight crew included commander James Lovell, who graduated from high school in Milwaukee and attended UW-Madison.

Apollo 13 never made it to the moon. After the explosion of an on-board oxygen tank – "Houston, we've had a problem" – the astronauts were able to navigate a safe return to Earth.

Lovell, John Swigert and Fred Haise splashed down in the South Pacific Ocean on April 17, five days before the first Earth Day.

Read our expanded coverage for more about Earth Day and historic events from 1970 – all celebrating 50th anniversaries this year.
