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 #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.

Space Rocket History #159 – Zond 6

Trouble began on the sixth day of the flight, November 17. The capsule developed an atmospheric  leak, the pressure first dropping from 760 to 380 mm of Mercury.  With the drop in cabin pressure all the animal test subjects died.  It would have killed any Cosmonaut not wearing a spacesuit.
