50 years later: Apollo 13 still Mission Control’s finest hour.
Astronauts Jim Lovell and Fred Haise recall the Apollo 13 mission, considered NASA’s most successful failure
CAPE CANAVERAL, FLA. » Apollo 13’s astronauts never gave a thought to their mission number as they blasted off for the moon 50 years ago. Even when their oxygen tank ruptured two days later — on April 13.
Jim Lovell and Fred Haise insist they’re not superstitious. They even use 13 in their email addresses.
As mission commander Lovell sees it, he’s incredibly lucky. Not only did he survive NASA’s most harrowing moonshot, he’s around to mark its golden anniversary.
“I’m still alive. As long as I can keep breathing, I’m good,” Lovell, 92, said in an interview with The Associated Press from his Lake Forest, Illinois, home.
A half-century later, Apollo 13 is still considered Mission Control’s finest hour.
Lovell calls it “a miraculous recovery.”
Haise, like so many others, regards it as NASA’s most successful failure.
“It was a great mission,” Haise, 86, said. It showed “what can be done if people use their minds and a little ingenuity.”
As the lunar module pilot, Haise would have become the sixth man to walk on the moon, following Lovell onto the dusty gray surface. The oxygen tank explosion robbed them of the moon landing, which would have been NASA’s third, nine months after Apollo 11’s Neil Armstrong and Buzz Aldrin took humanity’s first footsteps on the moon.
Now the coronavirus pandemic has robbed them of their anniversary celebrations. Festivities are on hold, including at Kennedy Space Center in Florida, where the mission began on April 11, 1970, a Saturday just like this year.
That won’t stop Haise, who still lives in Houston, from marking what he calls “boom day” next Monday, as he does every April 13.
A loud bang
Lovell, Haise and Jack Swigert, a last-minute fillin who died in 1982, were almost to the moon when they heard a bang and felt a shudder. One of two oxygen tanks had burst in the spacecraft’s service module.
The tense words that followed are the stuff of space — and movie — fame.
“OK, Houston, we’ve had a problem here,” radioed Swigert, the command module pilot.
“This is Houston. Say again, please.”
“Houston, we’ve had a problem,” Lovell cut in.
Lovell reported a sudden
voltage drop in one of the two main electrical circuits. Within seconds, Houston’s Mission Control saw pressure readings for the damaged oxygen tank plunge to zero. The blast also knocked out two electrical powergenerating fuel cells and damaged the third.
As Lovell peered out the window and saw oxygen escaping into the black void, he knew his moon landing was also slipping away. He shoved all emotions aside.
“Not landing on the moon or dying in space are two different things,” Lovell explained, “and so we forgot about landing on the moon. This was one of survival. How do we get home?”
The astronauts were 200,000 miles from Earth. Getting back alive would require calm, skill and, yes, luck.
“The explosion could not have happened at a better time,” Lovell said.
Much earlier, he said, and the astronauts wouldn’t have had enough electrical power to make it around the moon and slingshot
back to Earth for a splashdown. A blast in lunar orbit or, worse still, while Lovell and Haise were on the surface, “that would be the end of it.”
Divine intervention
“I think we had some divine help in this flight,” Lovell said.
For the record, flight director Gene Kranz in Houston never uttered “Failure is not an option.” The line is pure Hollywood, created for the 1995 movie “Apollo 13” starring Ed Harris as Kranz and Tom Hanks as Lovell.
The flight controllers went into crisis mode. They immediately ordered the command module Odyssey shut down to conserve what little power remained, and the astronauts to move into the lunar module Aquarius, now a lifeboat. One of the low points, Lovell said, was realizing they’d be cramped together in the lander.
The carbon dioxide overload, from breathing, threatened to kill them.
Engineers scrambled to figure out how to convert
the square air-purifying canisters in the dead capsule into round ones that would fit in their temporary home.
Their outside-the-box, seat-of-the-pants solution, using spacecraft scraps, worked. But it was so damp and cold that the astronauts couldn’t sleep. Condensation covered the walls and windows, and the temperature was close to freezing.
Dehydrated and feverish, Haise had the roughest time during the sixday ordeal. Despite the sky-high stress, Haise recalls no cross words among the three test pilots. Even Swigert fit in, despite joining the crew a scant three days before liftoff.
He replaced command module pilot Ken Mattingly, who with his crewmates had been exposed to German measles, but unlike them didn’t have immunity.
Rumors swirled that the astronauts had poison pills tucked away in case of a hopeless situation. Lovell dispelled that notion on page one of his 1994 autobiography, “Lost Moon,” the basis for the “Apollo 13” film.
Splashdown day finally arrived April 17, 1970 — with no guarantees.
The astronauts managed to power up their command module, avoiding short circuits but creating a rainfall inside as the spacecraft decelerated in the atmosphere.
The communication blackout lasted 1 ½ minutes longer than normal. Controllers grew alarmed. Finally, three billowing parachutes appeared above the Pacific. It was only then, Lovell said, that “we knew that we had it made.”
The astronauts had no idea how much their cosmic cliffhanger impacted the world until they reached Honolulu. President Richard Nixon was there to greet them.
“We never dreamed a billion people were following us on television and radio, and reading about us in banner headlines of every newspaper published,” Lovell noted in a NASA history.
The tank explosion later was linked to damage caused by electrical overheating in ground tests.
Apollo 13 “showed teamwork, camaraderie and what NASA was really made of,” said Columbia University’s Mike Massimino, a former shuttle astronaut.
In the decades since, Lovell and his wife of nearly 68 years, Marilyn, have discussed the what-ifs and might-have-beens.
“The outcome of everything is, naturally, that he’s alive,” she said, “and that we’ve had all these years.”
