Not so complicated

 In the early days of space exploration, both NASA and the Soviet space program initially used pencils as writing instruments. However, using pencils presented some problems. Pencil tips could break, creating floating debris in the spacecraft, which could potentially damage sensitive equipment or harm astronauts. Moreover, the wood and graphite in pencils could pose combustion risks in the oxygen-rich environment of the spacecraft.

To address these issues, NASA did invest in the development of a specialized writing instrument, known as the Fisher Space Pen, in the mid-1960s. This pen used a pressurized ink cartridge that allowed it to write in zero gravity, underwater, over grease, and in extreme temperatures. The Fisher Space Pen was not only used by NASA but also became a widely used writing tool in other industries, including the military.

The Soviet space program also eventually adopted the Fisher Space Pen, recognizing its advantages over pencils.

So, while the story is often simplified to suggest that NASA spent a lot of money and effort developing a pen while the Russians simply used a pencil, the reality is that both space agencies eventually adopted the same solution, which was the development of a reliable and safe writing instrument suitable for use in the unique conditions of space.

Our salvation is also not so complicated like many people think.  It is very simple, believe in Jesus, repent, reconcile, and love one another.
