The Mammoth Book of Space Exploration and Disasters

“We’ve got a sun,” Swigert said.

“We’ve got a big one,” Lovell responded with a smile.

“You see anything, Freddo?”

“No,” Haise said, squinting into his telescope. Then, as his eyepiece filled with light, “Yes, maybe a third of a diameter.”

“It’s coming in,” Lovell said, glancing out the window and turning away as the sun filled it. “I think it’s coming in.”

“Just about there,” said Haise.

“We’ve got it,” Lovell called. “I think we’ve got it.”

“OK,” Haise said, watching as the disk of the sun brushed the cross hairs of the telescope and slid downward. “Just about there.”

“Do you have it?” Lovell asked.

“Just about there,” Haise repeated.

In the telescope, the sun slid down another fraction of a degree, then a fraction of a fraction. The thrusters puffed hypergolics for another second or so, and then, silently, they cut off as the ship – and the sun – came to a stop. Lovell said, “What have you got? What have you got?”

Haise said nothing, then slowly pulled away from the telescope and turned to his crewmates with a huge grin.

“Upper right corner of the sun,” he announced.

“We’ve got it!” Lovell shouted, pumping a fist in the air.

“We’re hot!” Haise said.

“Houston, Aquarius,” Lovell called.

“Go ahead, Aquarius,” Brand answered.

“OK,” said Lovell, “It looks like the sun check passes.”

“We understand,” Brand said. “We’re kind of glad to hear that.”

In Mission Control, where only moments before, Gerald Griffin had called for absolute quiet, a whoop went up from the RETRO, FIDO, and GUIDO in the first row. It was taken up by the INCO and the TELMU and the Surgeon in the second row. Across the room, an undisciplined, unprecedented utterly un-NASA-like ovation slowly spread.

“Houston, Aquarius,” Lovell called through the noise. “Did you copy that?”

“Copy,” Brand said through his own broad grin.

“It’s not quite centered,” the commander reported. “It’s a little bit less than a radius to one side.”

“It sounds good, it sounds good.”

Brand glanced over his shoulder and smiled at Griffin who grinned back and let the tumult go on around him. Disorder was not a good thing in Mission Control, but for a few more seconds, at least, Griffin would allow it. He pulled his flight log toward him, and in the blank space under the Ground Elapsed Time column he wrote, “73:47.” In the space under the Comments column, he scribbled, “Sun check complete.” Looking down, the flight director discovered for the first time that his hands were shaking. Looking at the page, he discovered for the first time, too, that his last three entries were completely illegible.

As the LEM moved onto the dark side of the moon, the crew were able to use the position of the stars to check their alignment for the PC + 2 burn. They were out of radio contact for 25 minutes – when they regained contact they had accelerated because of the moon’s gravity. Vance Brand was Capcom at the time of the PC + 2 burn. He called 2 minutes 40 seconds to burn.

There was a long silence.

“One minute,” Brand announced.

“Roger,” Lovell answered. Sixty more seconds of silence.

“We’re burning 40 percent,” the radio officer now heard Lovell call.

“Houston copies.” Fifteen seconds passed.

“One hundred percent,” Lovell said.

“Roger.” Static roared in the background. “Aquarius, Houston. You’re looking good.”

“Roger,” Lovell crackled back. Another sixty seconds passed.

“Aquarius, you’re still looking good at two minutes.”

“Roger,” Lovell said. More static, more silence.

“Aquarius, you’re go at three minutes.”

“Roger.”

“Aquarius, ten seconds to go.”

“Roger,” Lovell said.

“Seven, six, five, four, three, two, one,” Brand ticked off.

“Shutdown!” Lovell called.

“Roger. Shutdown. Good burn, Aquarius.”

“Say again,” Jim lovell shouted hack through the radio hiss.

Brand raised his voice. “I – say – that – was – a – good – burn.”

“Roger,” Lovell said. “And now we want to power down as soon as possible.”

Splash down would be 600 miles east of US Samoa, on Friday. Meanwhile Houston decided the crew had to execute Passive Thermal Control and then power down and get some sleep. They were still 225,000 miles from home.

Ed Smythe was chief of the crew systems division. He had to solve the problem of cleaning the air of carbon dioxide, which was done by lithium hydroxide cartridges. Unfortunately the cartridges of the two modules were not interchangeable – the LEM’s cartridges were round but the command module’s were square. The LEM’s remaining cartridge would expire when the duration of the mission reached 85 hours.

For the next hour, the work aboard Apollo 13 had little more orderliness than a scavenger hunt, and little more technical elegance. With Kerwin reading from the list of supplies Smylie had provided him, and Kraft, Slayton, Lousma, and other controllers standing behind him and consulting similar lists, the crew were dispatched around the spacecraft to gather materials that had never been intended for the uses to which they were about to be put.

Swigert swam back up into Odyssey and collected a pair of scissors, two of the command module’s oversized lithium hydroxide canisters, and a roll of gray duct tape that was supposed to be used for securing bags of refuse to the ship’s bulkhead in the final days of the mission. Haise dug out his book of LEM procedures and turned to the heavy cardboard pages that carried instructions for lifting off from the moon-pages he now had no use for at all – and removed them from their rings. Lovell opened the storage cabinet at the back of the LEM and pulled out the plastic-wrapped thermal undergarments he and Haise would have worn beneath their pressure suits while walking on the moon. No ordinary long johns, these one-piece suits had dozens of feet of slender tubing woven into their fabric, through which water would have circulated to keep the astronauts cool as they worked in the glare of the lunar day. Lovell cut open the plastic packaging, tossed the now useless union suits back into the cabinet, and kept the now priceless plastic with him.

When the materials had been gathered, Kerwin began reading up the assembly instructions Smylie had written. The work was at best slow going.

“Turn the canister so that you’re looking at its vented end,” Kerwin said.

“The vented end?” Swigert asked.

“The end with the strap. We’ll call that the top, and the other end the bottom.”

“How much tape do we want to use here?” Lovell asked.

Kerwin said, “About three feet.”

“Three feet…” Lovell contemplated out loud.

“Make it an arm’s length.”

“You want that tape to go on sticky end down?” Lovell asked.
