Space Rocket History #181 – Apollo 9 – Lunar Module Maneuvers Part 2

McDivitt later said that the engine had come on abruptly, but with the tremendous mass, acceleration was very slow – it took the whole 5 seconds to add 11 meters per second to the speed.


Space Rocket History #180 – Apollo 9 – Lunar Module Maneuvers

As Dave Scott pulled in closer to the Lunar Module he noticed that the command module’s nose was out of line with the lander’s nose. Scott tried to use a service module thruster to turn left, but that jet was not operating. It turns out that someone had accidentally bumped a switch that turned off one set of Thrusters. The crew then flipped the correct switches, and the thruster started working, and at T+3 hours 2 minutes the command module probe nestled into the lunar Module drogue, where it was captured and held by the 12 latches. The first docking of the Lunar Module in space was achieved. As a side note, switch guards were installed on all future Apollo missions to prevent accidentally flipping a switch.

Space Rocket History #179 – Apollo 9 – The Launch

For the 19th flight of American astronauts into space, Vice President Spiro T. Agnew, representing the new administration of Richard Nixon, sat in the firing control room viewing area on March 3rd, 1969. He and other guests listened to the countdown of the Saturn-Apollo structure several kilometers away at the edge of the Florida beach.

Space Rocket History #178 – Apollo 9 – The Crew – McDivitt, Scott, Schweickart

James Alton “Jim” McDivitt was born on June 10, 1929, in  Chicago, Illinois. He is of  Irish descent. Like many other astronauts, he was a  Boy Scout and earned the rank of Tenderfoot Scout. He graduated from Kalamazoo Central High School, Kalamazoo, Michigan, in 1947.

Space Rocket History #177 – Apollo 9 – Preparations

The biggest concern before Apollo 9 was the docking maneuver.  In early 1969, at NASA there was little confidence in the docking system. At a January program review, Phillips said that problems encountered during probe and drogue testing worried him…

Space Rocket History #176 – The First Test Flight of the Soviet N1

Finally, on the morning of February 21, all the population of the N1 assembly area and a residential area, situated just south of the launch pad, was ordered to evacuate. The giant service structure then rolled away leaving the dark-gray rocket with a white payload fairing towering under sunny skies. The weather was extremely cold, with temperatures falling to minus 44 C degrees, and stormy winds.  In the fortified firing control room, the Commander of the 6th Directorate, took the firing command position at the main periscope…

Space Rocket History #175 – Early History of the Soviet N1 – Part 2

On August the third 1964 Decree number 655-268 was issued by the Central Committee of the Communist Party. For the first time a command was given for OKB-1 to put one man on the moon and return him safely to earth before the United States (Keep in mind the US already had already begun their Lunar program more than three years earlier, in April 1961).

Space Rocket History #174 – Early History of the Soviet N1 – Part 1

The L-3 manned spacecraft was designed to make a direct lunar landing using the earth orbit rendezvous method. It was a 200 metric ton spacecraft requiring three N1 launches and a single Soyuz 11A5ll launch to assemble in low earth orbit. The first N1 launch would place the 75 metric ton partially-fueled Trans Lunar Injection stage and L3 spacecraft into low earth orbit. Two further N1 launches would orbit 75 metric ton tankers which would rendezvous and dock with the first payload and top off its propellant tanks. Then the Soyuz would be launched for an automated rear-end docking with the entire L3 stack.

Space Rocket History #173 – Soyuz 4 & 5 – World’s First Space Station? – Part 2

Vladimir Shatalov would become the Soviet Union’s 13th space traveler, his home telephone number ended in “13” and the launch itself was set for 13:00 hours Moscow Time, on January 13th, 1969.

Space Rocket History #172 – Soyuz 4 & 5 – World’s First Space Station? – Part 1

The objectives of the Soyuz 4 & 5 mission were to dock two manned Soyuz 7K-0Ks, transfer two Cosmonauts from Soyuz 5 to Soyuz 4 by means of a space walk, and then safely return both crews to earth.
