...like petals of a flower, righted itself and exposed its TV camera and transmitter. Luna 16 was a far more sophisticated instrument. Although the Soviets revealed few details, Western space experts believe that the spacecraft that descended to the lunar surface weighed about a ton (compared with the Apollo LM's 8 tons); it was braked first by its main engine and then in the last few yards of descent by smaller thrusters. The landing operation on the Sea of Fertility, an unexplored portion of the moon about 200 miles east of Apollo 11 's landing site...
...were jettisoned after rounding the moon, a long burn of the small Aquarius descent engine would impart about the same velocity to the lightened spacecraft, setting it down in the South Atlantic in less than 40 hours. But that strategy too carried unnecessary risks. It would so deplete the LM's fuel supply that later course corrections might not be possible. Also, loss of the service module would expose the command module's heat shield to possibly damaging ultraviolet radiation and temperature extremes, leaving the astronauts with insufficient protection for reentry...
About 30,000 miles from earth, the astronauts began preparing for their final separation maneuver. Climbing into Odyssey, they switched on its oxygen tanks and batteries and sealed the hatch shut. Then the crew exploded the small bolts connecting the command module with the LM. Propelled by the release of air in the connecting tunnel, the Aquarius drifted rapidly away, its lifeboat function reliably and amply fulfilled. "LM jettison," reported Apollo 13. "O.K.," replied Mission Control. "Farewell, Aquarius, and we thank...
...dangerous level in the lunar module's atmosphere; lithium hydroxide air purifiers in Aquarius, designed to absorb the potentially lethal gas for only relatively short periods of time, were becoming saturated. The deactivated command module was equipped with more purifiers, but their canisters were not interchangeable with the LM's. Mission Control instructed the astronauts to lead a second hose into the command module and connect it to the canisters. Leaving nothing to chance, the astronauts stuffed a sock in the connection to make sure it was snug...
...minutes later, Apollo 13 began its novel separation procedures. Again hitting the thrusters, Lovell forced Aquarius against the command and service modules. Almost simultaneously, Swigert fired several explosive bolts, detaching the service module from Odyssey. Lovell also fired the LM's thrusters again. The "push-pull" tactic shoved the service module away from Aquarius and Odyssey, enabling the astronauts to see the disabled module for the first time. It was an incredible sight. The module had lost an entire 15-foot-long panel covering Bay 4, and a tangle of wiring and debris trailed out of the gaping hole. Using...
