우주 연필 vs 우주 볼펜


러시아 우주인의 연필과 수백만달러짜리 미국 우주인의 볼펜에 대한 얘기가 오랫동안 회자된다.
여기저기서 근거확인없이 반복적으로 인용되기 때문인데 이렇게 도시전설로 굳어진 경우 대개 오류가 바뀌지 않는다.

라면 점유율과 관련한 오해도 그런 예라 할 수 있다.

무중력 상태에서 일반 볼펜은 써지지 않는다고.
무중력 상태에서 일반 연필은 부러진 연필심이 눈이나 콧구멍으로 들어가고 자연발화의 위험이 있다고.
그래도 러시아인들은 우주에서 강화연필을 쓸까?
아직도 미국인들은 그 비싸다는 우주 볼펜을 쓸까?

확인한 사항은?

미국인도 러시아인도 그 펜을 쓴다는 것.
지금은 5만원이면 그 펜을 살 수 있다는 것.
예전에도 그 펜은 쌌다는 것.
개발비는 들었다는 것.
위키피디아는 참 훌륭하다는 것.

A common urban legend states that NASA spent a large amount of money to develop a pen that would write in space (the result purportedly being the Fisher Space Pen), while the Soviets just used pencils.[2][3] There is a grain of truth: NASA began to develop a space pen, but when development costs skyrocketed the project was abandoned and astronauts went back to using pencils, along with the Soviets.[2][3] However, the claim that NASA spent millions on the Space Pen is incorrect, as the Fisher pen was developed using private capital, not government funding. NASA – and the Soviets[3][4][5] – eventually began purchasing such pens.

NASA programs previously used pencils[6] (for example a 1965 order of mechanical pencils[7]) but because of the substantial dangers that broken pencil tips and graphite dust pose to electronics in zero gravity, the flammable nature of wood present in pencils,[7] and the inadequate quality documentation produced by non-permanent or smeared recordkeeping, a better solution was needed. Russian cosmonauts used pencils, and grease pencils on plastic slates until also adopting a space pen in 1969 with a purchase of 100 units for use on all future missions.[8] NASA never approached Paul Fisher to develop a pen, nor did Fisher receive any government funding for the pen's development.[7] Fisher invented it independently and then, in 1965, asked NASA to try it. After extensive testing, NASA decided to use the pens in future Apollo missions.[6][8][9] Subsequently, in 1967 it was reported that NASA purchased approximately 400 pens for $6 a piece.[8]
