What was it like to work on Apollo 13? Mission engineers to recall the hair-raising flight in webcast today.

Fifty years after Apollo 13, you can hear NASA's Apollo engineers discussing live what it was really like to work at the agency during one of its most hair-raising missions. 

The live broadcast, titled "Splashdown! A discussion with the engineers who helped bring Apollo 13 home," will begin today (April 17) at 2 p.m. EDT (1800 GMT) — almost exactly 50 years after the Apollo 13 mission returned to Earth. The three-person crew of Apollo 13 safely splashed down in the Pacific Ocean on April 17, 1970, at 2:07 p.m. EDT (1807 GMT). 

The webcast will be hosted by author John Rocco, who most recently wrote and illustrated the book "How We Got to the Moon," (Random House Children's Books, 2020). Joining Rocco will be Ed Smith, chief engineer for the Apollo command and service module; Don Rethke, an Apollo lunar module life support systems engineer; and Chuck Lowry, an Apollo parachute system designer.

The three retired engineers will talk about their experiences working behind the scenes at NASA during the harrowing Apollo 13 mission, when three astronauts almost didn't make it back to Earth alive. 

Apollo 13 was chock-full of difficulties and obstacles. Following an oxygen tank explosion 56 hours into what was supposed to be a lunar landing mission, NASA's mission controllers, engineers and the Apollo 13 astronauts themselves — Jim Lovell, Jack Swigert and Fred Haise — had to fly into action to bring the astronauts safely back home to Earth. 

This past week, people around the world have been remembering and celebrating the mission, which has famously been known as a "successful failure." While the Apollo 13 astronauts never landed on the moon, the ingenuity from everyone who supported the mission at NASA and their ability to bring the crew back home alive and safe remains remarkable.

Rocco's "How We Got to the Moon" will be released on Oct. 6.
