Steam cars are at least as efficient as gasoline engines, Jamison says. And, because steam cars burn their fuel more completely than gasoline engines, they are virtually pollution-free...
...behind the moon, they would splash down in the Atlantic off the coast of Brazil in only 38 hours. Again Mission Control decided not to risk firing a possibly damaged engine. If, on the other hand, the 26-ton service module 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...
Hurry-Home Burn...
Apollo 13 itself reached the moon Tuesday night, but it never came closer than 158 miles. As it emerged from behind the far side, the astronauts prepared for the crucial "hurry-home" burn. But there was a hitch. So much debris was still floating outside the spacecraft's windows that a star sighting?to align Apollo properly for the burn?was impossible ("It looks like we're in the middle of the Milky Way," the astronauts had remarked earlier). But the spacemen neatly improvised by taking rougher fixes on the moon and the sun. Then they fired Aquarius' descent engine...
...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 still and movie cameras, the astronauts managed to photograph the damage; because the service module would burn up on reentry, the pictures would be important to scientists investigating the cause of the blast. "It's really a mess," Lovell told Mission Control. "Well, James," Houston answered, "if you can't take any better care of the spacecraft than that, we might not give you another...
