The first spacewalker

On march 18th 1965, Voskhod 2 with Pavel Belyayev and Alexei Leonov was launched for a day long trip in space at 500 km height (very high!!).

The spacecraft had no ejection seats nor launch escape tower and they knew that if anything happened before 18 seconds into the flight, they would not survive it.

Right after reaching orbit, the inflatable airlock chamber is extended (2 meters long). Leonov waited to be above the Caucasus mountains to get out. Whe he got out he felt overwhelmed, but his 4 years old daughter was shouting in front of the TV: What is he doing? Tell daddy to get back inside!

His painting of his spacewalk.

When he had to come back in (before sunset), he noticed his spacesuit was too inflated to allow him to get back in the chamber. He opened a pressure valve to let air go (without reporting to anybody); once inside, he had to curl his body round to reach the hatch so that he could close the hatch. Pavel opened the inner hatch and Alexei got back in in full sweat.

When the chamber was ejected, it sent the spaceship into a tumbling motion (one rotation every 21 seconds) that wasn't stopped until just before re-entry, in order to save fuel.

The oxygen pressure went very high; a leak perhaps; it went back down during their sleep.

Just before landing, they realized they will have to do it manually. The miss their first opportunity; get permission to do it next time. It happens. During re-entry, a cable linking the landing module to the orbital module had not been cut. At 100km altitude, the heat does it and the capsule stops spinning.
The cosmonauts landed right inside a forest. The hatch was blocked by a tree; they rocked the hatch , clear of the tree.
They were in the snow, the cold and had to get out of their spacesuits (Alexei's was loaded with water from his sweat).

Rescuers knew where they were before the end of the day, but could not reach them soon enough.
They had to wait 2 days before skiing to a safer place.

These were the old days of space exploration, the Soviet way...I recommend this book.

And in 1998, he came to Antwerp (we was not alone).
