Space Rocket History #257 – Apollo 12 – Return, Re-entry and Splashdown

Ten days ago, their Saturn V rocket had blasted Bean and his crew mates out of earth’s gravitational pull. Now their home planet was pulling them back at more than 24,000 miles per hour, twelve times faster than a high-speed rifle bullet. “Boy,” said Bean, “we are really hauling!” Homepage with pictures

Space Rocket History #256 – Apollo 12 – Leaving the Moon

Dick Gordon opened the tunnel to Intrepid, saw his companions floating in a dirty cloud of moon dust, and slammed the hatch closed. He called out, “You guys ain’t gonna mess up my nice clean spacecraft!” Homepage with pictures

Space Rocket History #255 – Apollo 12 – Lunar Liftoff

After a total of 31.6 hours on the moon, the Lunar Module ascent stage fired for about 7 minutes placing Intrepid into an orbit of 10 miles by 54 miles. Homepage with pictures

Space Rocket History #254 – Apollo 12 – Moonwalk 2 – Part 5 – Blocky Crater & Closeout

Conrad and Bean now walked north, up Surveyor Crater’s 14 degree slope. Fatigue set in as Pete and Al walked up the crater wall. The hand tool carrier was nearly full of rocks now and Bean felt the full weight of it. Homepage with pictures

Space Rocket History #253 – Apollo 12 – Moonwalk 2 – Part 4 – Surveyor Crater & Surveyor 3

Surveyor 3 was now to their right, 300 feet away, gleaming in the morning sunlight. Antennas and sensors still reached upward from its tubular frame, just as they had on April 20, 1967, when the spacecraft thumped onto the moon amid blasts from its braking rockets. Homepage with pictures.

Space Rocket History #252 – Apollo 12 – Moonwalk 2 – Part 3 – Rock ‘n’ Roll at Halo Crater

The problem with running into the sun was it was so bright that Conrad and Bean could not see the moon’s surface features until they were right on top of them. Homepage with Pictures

Space Rocket History #251 – Apollo 12 – Moonwalk 2 – Part 2 – Bench and Sharp Craters

While Conrad led the way, Bean watched the ground for something interesting. It wasn’t easy to do field geology while running, and on the moon. Homepage with pictures

Space Rocket History #250 – Apollo 12 – Moonwalk 2 – Part 1 – Head Crater – Tang Ceremony

Pete and Al could not hear the excited shouts of the geologists in the back room down the hall from mission control, but they knew they had found something significant. Homepage with pictures

Space Rocket History #249 – Apollo 12 – Moonwalk 1 – Part 3

Most of the remaining moon walk time was spent collecting rock samples, making surface observations such as the small mounds or hills, and taking pictures. Homepage with Pictures

Space Rocket History #248 – Apollo 12 – Moonwalk 1 – Part 2 – ALSEP

According to the checklist, Bean was allowed 5 minutes to gain his balance and learn to walk on the Moon. Bean was amazed at his new buoyancy saying, “You can jump up in the air…”  But Conrad wanted to press on saying, “Hustle, boy, hustle! We’ve got a lot of work to do.” Homepage with Pictutures

“The old Surveyor, yes sir. It can’t be any more than 600 feet from here. How about that?” (Pete Conrad.) Homepage with Pictures

Space Rocket History #246 – Apollo 12 – Pin Point Landing Part 2 – Right Down the Middle of the Road

“Hey, there it is! There it is! Son of a gun, right down the middle of the road! Look out there! I can’t believe it! Fantastic!”  Pete Conrad when he saw his landing site. Homepage with Pictures

Space Rocket History #245 – Apollo 12 – Pin Point Landing Part 1 – Right Down the Middle of the Road

There was adrenaline in Pete Conrad’s voice as he counted down the last seconds before ignition. He and Bean were still weightless, but their bodies were secured to the cabin floor by harnesses. “Seven, six, five.”  Conrad pushed the PROCEED button on the computer, and a moment later Intrepid’s  descent engine ignited 50,000 feet above the moon.

Space Rocket History #244 – Apollo 12 – Lunar Orbit

At 83 hours mission elapsed time, the long lunar coast was almost over. It was time for the lunar orbit insertion burn. This burn would put Yankee Clipper and Intrepid into lunar orbit. Homepage with Pics

Space Rocket History #243 – Apollo 12 – TLI and the Coast

It was impossible to check out the entire spacecraft; that could only be done on the ground. In the short time available, Griffin’s team ran a pre-maneuver check list, re-aligned the CSM platform, and discussed proceeding with the mission with the crew. Homepage with Pics.

Space Rocket History #242 – Apollo 12 – The Launch Part 2

John Aaron’s (EECOM) next call made him a legend in Mission Control. He said quickly and confidently, “Flight, try S-C-E to Aux.” Homepage with pics

Space Rocket History #241 – Apollo 12 – The Launch Part 1

It was 68 degrees, overcast, and raining at Cape Kennedy on November 14, 1969. The ceiling was 2,100 feet and the winds were light. There was some discussion, while the astronauts were suiting-up, of scrubbing the launch, but that would mean ramping this whole thing down, draining every drop of fuel out of the Saturn, and sitting on their hands for a twenty-eight-day hold.

Space Rocket History #240 – Apollo 12 – Saturn V Instrument Unit

The Saturn V’s control system was housed inside and also referred to as the Instrument Unit (IU). Marshall Space Flight Centers Astrionics Laboratory categorized the IU as the “brain” and “nerve center” of Saturn V. Homepage with Pics
