NASA'S SPACE PEN
AT THE BEGINNING HUMANS STARTED PEEPING INTO THE GIGANTIC OUTER SPACE BEING ON EARTH ...BUT AS THE TIME PASSED ON, WE CAME UP WITH AN INTERESTING IDEA OF VISITING SPACE WHICH RESULTED IN MANY GREAT INVENTIONS ALL ALONG.
ONE SUCH INVENTION WAS THE "SPACE PEN"
THE INVENTION OF THE SPACE PEN WAS FIRST CONSIDERED IMPRACTICAL AND WAS THOUGHT OF A TRUFFLE WHEN WAS COMPARED TO A NORMAL GRAPHITE PENCIL, BUT SLOWLY AS THE TIME PASSED BY THE IDEA WAS ACCEPTED.
THE BRIEF HISTORY
THE VERY POPULAR FACT DRIVING THROUGH THE INTERNET SUGGESTS THAT THE SO-CALLED SPACE PEN WAS DESIGNED BY NASA COSTING MILLIONS OF DOLLARS...
WHICH IS INFACT, NOT THE TOTAL REALITY BEHIND IT.
FROM THE 1960s THERE IS AN UNREVEALING RIVALRY AMONG "NASA" AND THE "SOVIET UNION".
THE SOVIET UNION SPACE AGENCY PREFERRED THE "PENCILS" INSTEAD OF THESE COSTLY SPACE PENS.
AT THE END THE RUSSIAN SPACE AGENCY STARTED THE USE OF THESE SPACE PENS.
IDEA BEHIND THE INVENTION
THE "SPACE PEN" OR MORE PRECISELY THE “FISHER SPACE PEN” WAS AN IDEA OF THE FOUNDER OF THE FISHER PEN COMPANY, “PAUL C. FISHER”
AT THE TIME OF "SPACE RIVALRY" BETWEEN NASA AND SOVIET UNION, PAUL FISHER SAW A GREAT OPPORTUNITY TO PROMOTE HIS OWN COMPANY "FISHER PEN COMPANY" AND INVENTED THE "FISHER SPACE PEN" WHICH COULD WRITE UNDER THE ZERO GRAVITY OR "MICROGRAVITY" CONDITION
IT COULD WORK UNDER EXTREME TEMPERATURE CONDITIONS, FROM "-46 DEGREE CELSIUS TO 76 DEGREE CELSIUS" WHICH WAS ASTONISHING.
THE FISHER SPACE PEN COULD BE USED TO WRITE IN ANY SURFACE, AT "ANY ANGLE" AND IT WORKED IN VACUUM.
THE FACT THAT THE PEN COST A MILLION DOLLAR IS ALSO NOT FALSE, INFACT THE R&D (RESEARCH AND DEVELOPMENT) OF THE FISHER SPACE PEN HAD A BUDGET OF MILLION DOLLARS WHICH GAVE OUT THIS PRICE TAG.
PROBLEM WITH USING PENCILS
THE ISSUE OF USING PENCILS IN SPACE WAS FIRST NOTICED IN THE "GEMINI 3 MISSION" IN 1965.
ONE OF THE CREW MEMBERS OF THE MISSION HAD SMUGGLED A "SANDWICH" IN HIS SPACESUIT WHICH FURTHER CREATED ISSUES IN THE ELECTRONICS OF THE SPACESHIP, DUE TO THE FLOATING PARTICLES IN THE MICROGRAVITY.
THE SAME PROBLEM WAS WITH THE "PENCIL LEADS" WHICH COULD CREATE DISTURBANCE IN THE ELECTRONICS OF THE SPACESHIP AND COULD ALSO HARM THE ASTRONAUTS.
THIS PROBLEM OF NASA WAS KNOWN BY PAUL C. FISHER GIVING HIM AN IDEA OF DEVELOPING A SPACE PEN.
WORKING OF FISHER SPACE PEN
THE MAIN PROBLEM WHY BALL PENS, GEL PENS OR FOUNTAIN PENS CAN'T BE USED IN SPACE IS THE "ZERO GRAVITY" OR THE MICROGRAVITY IN SPACE.
A BALLPOINT PEN WORKS WHEN THE INK ON THE REFILL IS PUSHED DOWNWARDS BY THE GRAVITY WHEN THE BALL AT THE TIP OF THE PEN ROLLS ON THE SURFACE THE INK DESPENSES OUT DUE TO PRESSURE CREATED BY GRAVITY.
THIS MECHANISM OF BALLPOINT PEN WAS MADE BY "JHON J. LOUD" IN THE "1888"
A SIMILAR MECHANISM IS USED IN THE FISHER SPACE PEN. THE PEN HAS A SPECIAL INK CARTRIDGE CONTAINING A "SOLID INK" WHICH TRANSFORMS INTO LIQUID INK AT A SPECIFIC PRESSURE. THE SPECIFIC PRESSURE REQUIRED IS FURNISHED BY THE "NITROGEN" CYLINDER ENCLOSED IN THE PEN.
THE FISHER SPACE PEN BASICALLY HAS A PRESSURIZED INK CARTRIDGE WHICH ALLOWS TO WRITE IN EXTREME CONDITIONS.
THE FISHER SPACE PEN COULD EVEN WRITE "UNDERWATER" MAKING IT A PERFECT PEN.
WITH THIS WORKING MECHANISM "PAUL C. FISHER" PATENTED HIS PEN "AG-7" OR THE "ANTIGRAVITY-7" WHICH WAS ALSO USED IN THE APOLLO MISSIONS OF NASA.
