Apollo 13 approached Earth on the morning of Friday, April 17. The astronauts were about to face the most dangerous part of their journey.
What if Odyssey’s electrical system couldn’t be powered up? What if Odyssey’s heat shield had been damaged in the explosion? What if the parachutes had turned to blocks of ice and didn’t open?
Incredibly, the astronauts had no trouble powering up Odyssey. But what about the heat shield? If it failed, the ship would burn up.
The world would know the fate of Apollo 13 in four minutes. That’s how long communication with Odyssey would be blacked out as it fell to Earth.
“Gentlemen,” Lovell said. “We’re about to re-enter. I suggest you get ready for a ride.”
The men tightened their seat belts as Odyssey began its 25,000-mile-per-hour free fall to Earth. Through the small windows, all they could see was fiery red.
At Mission Control, the command room was packed with engineers and visitors. Nobody spoke. The room was completely silent.
The minutes ticked by with agonizing slowness.
One minute.
Two minutes.
Three minutes.
Four minutes . . .
NASA’s Joe Kerwin tried to make contact. “Odyssey, Houston standing by, over.”
Nothing.
“Try again,” Kranz barked.
“Odyssey, Houston standing by, over.”
Still nothing.
Five minutes.
Some engineers fought back tears.
Then, a voice crackled over the radio.
“OK, Joe,” said Swigert.
At Mission Control, joy and relief flooded the entire room. Kranz pumped his fist.
Inside Odyssey, Lovell, Haise, and Swigert watched the sky outside the windows turn from angry red to soft pink and finally to blue. Their speed slowed as the air thickened.
Pop.
Odyssey’s parachutes opened.
The ship floated down to Earth, feather-like. It came to rest in the warm waters of the Pacific Ocean.
The Apollo 13 mission was over, a failed mission that would go down in history as one of NASA’s greatest successes.
Lovell looked at Haise and Swigert. “Fellows,” he said, “we’re home.”
