Space Rocket History #249 – Apollo 12 – Moonwalk 1 – Part 3 28.12.2023

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 28.12.2023

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

Space Rocket History #247 – Apollo 12 – Moonwalk 1 – Part 1 27.11.2023

“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 27.11.2023

“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 26.10.2023

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 26.10.2023

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 28.09.2023

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 28.09.2023

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 28.08.2023

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. Homepage with Pics

Space Rocket History #240 – Apollo 12 – Saturn V Instrument Unit 28.08.2023

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

Space Rocket History #239 – Apollo 12 – Commander Charles Conrad – Part 2 31.07.2023

Pete Conrad joined NASA as part of the second group of astronauts, known as the New Nine, on September 17, 1962. He was regarded as one of the best pilots in the group, and was among the first of his group to be assigned a Gemini mission.  

Space Rocket History #238 – Apollo 12 – Commander Charles Conrad – Part 1 31.07.2023

The third man to walk on the moon, Charles Conrad Jr. was born on June 2, 1930, in Philadelphia, to Charles and Frances Conrad. He was their third child and their first son. Homepage with Pictures

Space Rocket History #237 – Apollo 12 – Lunar Module Pilot Alan Bean – The Artist 30.06.2023

After completing a four-year tour of duty, he attended the U.S. Naval Test Pilot School at NAS Patuxent River, Maryland. He trained under the direction of Pete Conrad, who would later become Commander of the Apollo 12 moon flight, and who would be instrumental in getting Bean assigned to that mission.

Space Rocket History #236 – Apollo 12 – Command Module Pilot Richard “Dick” Gordon 30.06.2023

After graduating from the University of Washington, Gordon joined the US Navy, and after his first exposure to planes decided to become a pilot. Gordon said “Once I found what the airplane could do for me, or I could do for it, it was love at first sight.” Homepage with pictures.

Space Rocket History #235 – Apollo 12 – Introduction 28.05.2023

At NASA Headquarters, George Mueller and other planners created a far-reaching plan that Administrator Paine made even more ambitious in adapting it for Nixon’s Space Task Group. The task group’s timetable called for a twelve-man space station and a reusable space shuttle as early as 1975. By 1980, the station would have grown into a fifty-man space base; five years later there would be a hundred...

Space Rocket History #234 – Soyuz 6, 7, and 8 – Part 2 -The Vulcan Device 28.05.2023

The Vulcan device consisted of two major units. The first unit included various welding devices and a turn-table with samples of metals to be welded. The second unit consisted of an electric power pack, a protective shield which covered the welding unit, and a remote control console. click here for Homepage with pictures

Space Rocket History #233 – Soyuz 6, 7, and 8 with Shonin, Kubasov, Filipchenko, Volkov, Gorbatko, Shatalov, Yeliseyev – Part 1 28.04.2023

Finally, on April 25, 1969 during a meeting of the Soyuz State Commission, it was decided that the solo and docking flights outlined for 1969 by design bureau OKB-1 would be combined into a joint flight of three spacecraft.  The plan was to fly Soyuz 6, 7, and 8 together in August of 1969; Soyuz 7 and 8 would dock and 6 would rendezvous with the docked pair and take pictures of it as well as perfo...

Space Rocket History #232 – Apollo 11 – Final Duties & World Reaction Part 2 28.04.2023

The round-the-world tour began on September 29th and lasted until November 5th covering 28 cities in 25 countries in 38 days. The astronauts’ wives were allowed to go along on the trip, as well as a large staff. Homepage with Pictures

Space Rocket History #231 – Apollo 11 – Final Duties & World Reaction Part 1 31.03.2023

On August 10th, 1969 quarantine officially ended for the Apollo 11 crew, but that did not end the duties required for a flight of such magnitude. On August 12th, the Astronauts conducted a post flight press conference. They were greeted with a standing ovation from members of the media. Homepage with Pictures and more:

Space Rocket History #230 – Apollo 11 – Recovery, Nixon, & Quarantine 31.03.2023

The helicopter door slid open and Armstrong, Aldrin, and Collins stepped out of the helicopter onto the lower deck of the carrier Hornet to the accompaniment of a brass band. They appeared to many, like men from another world. They were outfitted from head to toe in gray-colored Biological Isolation Garments. Homepage with pictures and more

Space Rocket History #229 – Apollo 11 – Re-entry & Splashdown 28.02.2023

At launch, Apollo 11 weighed 6,000,000 pounds, now all that was left of Columbia weighed in at a mere 11,000 pounds. Homepage with Pictures

Space Rocket History #228 – Apollo 11 – The Return 28.02.2023

The next critical event in the Apollo 11 mission was the Trans-Earth Injection burn. The burn involved firing the big service propulsion engine for two and a half minutes on the back side of the moon. Homepage with Pictures

Space Rocket History #227 – Apollo 11 – Rendezvous, Docking and Jettisoning 28.01.2023

The ascent of the Eagle was strikingly swift compared with the liftoff of the huge Saturn V rocket from Cape Canaveral. Of course for the Moon launch, there was no atmosphere resisting Eagle, and there was only one-sixth gravity to overcome. Homepage with Pics

Space Rocket History #226 – Apollo 11 – Moon Launch 28.01.2023

Until now they had been focused on reaching the moon, landing, taking a walk on its surface, setting up experiments, exploring, and gathering evidence. With those tasks completed and their lunar bounty was board, the top priority was to fly back to Earth. Homepage with Pics

Space Rocket History #225 – Apollo 11 – Moonwalk – Part 3 14.12.2022

Without a word to Houston, while Buzz made his way back to Eagle, Armstrong took off running. Long strides carried Armstrong into the sun’s glare to the edge of a crater that looked to be 80 feet across and 15 or 20 feet deep. Homepage with pictures
