Writing in Space with a Cheap Ballpoint Pen
Roland Piquepaille writes "Some days bring big surprises. Like many people, I always believed that it was impossible to write in space with ordinary pens because ink would not flow. So imagine my astonishment when I read Pedro Duque's diary from space this morning. Pedro Duque is an astronaut since 1992. Now, he's on board of the International Space Station (ISS) since October 18, 2003. And he's writing -- from space -- with a cheap ballpoint pen, like Russians apparently always did: 'So I also took one of our ballpoint pens, courtesy of the European Space Agency (just in case Russian ballpoint pens are special), and here I am, it doesn't stop working and it doesn't "spit" or anything.' Isn't it amazing? This summary contains more details and a photograph of Pedro Duque on board ISS." Note that NASA didn't go crazy developing a pen for space. Surface tension is the important factor for all pens, not gravity.
if gravity doesn't matter, explain me why you can't use a sheet of paper and a ballpoint pen on a wall for more than 5 minutes ?
In the 60's we longed to use space technology to explore other worlds, and did a great job of it. Then we decided to make spaceflight routine and do great science on orbital space stations. They would be used as stepping stones to the Moon and Mars we were told. What we got is an expensive, perpetual, and feckless welfare program for the exploration of triviality. In the 30 years since Apollo we have answered such pressing questions as: How long does it take to get sick in space while spinning on a gyroscope? Can spiders spin webs in zero g? Can ballpoint pens work in space? With the exception of planetary missions, the current space program is a complete waste.
an ill wind that blows no good
And that's not a good thing to have in an environment dependent on technology...
I dont know about the US, but in India where we dont throw away pens that often (My dad believes that you should use a good "Hero" ink pen for life, and in general writing instruments are treated with some reverence), we just open up the pen, pull out the refill and blow into it. If even that doesnt work, remove the ball and the metal part holding it, blow air at back till ink comes out the other end and put the tip back on. Works everytime (remember to wipe ink off the hands and table).
"We spent millions of dollars developing the Space Pen program. Know what the Russians did? They used a pencil."
Its almost too neat not to be true, and in a way it is! Ok, in fact it was an independant company that spent $1 million on developing a "space" pen, and not NASA themselves, but in the end the US did spend the money, whereas the Russians were happy with the low-tech solution, although of course they took advantage of the high-tech solution once the money was spent.
The above Russian/US comparison probably holds up better today than the 60's - currently the US is spending $3 billion/year on the (white elephant) Shuttle, whereas the Russians are keeping the ISS running at under $100 million a mission.
Below is a related extract from a piece posted on www.space.com, by Robert Zubrin - an advocate of reform in the US space program - interesting reading...
In the recent Columbia hearings, numerous members of congress continually decried the fact that the US space program is "stuck in Low Earth Orbit." This is certainly a serious problem. If it is to be addressed adequately, however, America's political leadership needs to reexamine NASA's fundamental mode of operation.
Over the course of its history, NASA has employed two distinct modes of operation. The first, prevailed during the period from 1961-1973, and may therefore be called the Apollo Mode. The second, prevailing since 1974, may usefully be called the Shuttle Era Mode, or Shuttle Mode, for short.
In the Apollo Mode, business is conducted as follows. First, a destination for human spaceflight is chosen. Then a plan is developed to achieve this objective. Following this, technologies and designs are developed to implement that plan. These designs are then built, after which the mission is flown.
The Shuttle Mode operates entirely differently. In this mode, technologies and hardware elements are developed in accord with the wishes of various technical communities. These projects are then justified by arguments that they might prove useful at some time in the future when grand flight projects are initiated.
Contrasting these two approaches, we see that the Apollo Mode is destination driven, while the Shuttle Mode pretends to be technology driven, but is actually constituency driven. In the Apollo Mode, technology development is done for mission directed reasons. In the Shuttle Mode, projects are undertaken on behalf of various internal and external technical community pressure groups and then defended using rationales. In the Apollo Mode, the space agency's efforts are focused and directed. In the Shuttle Mode, NASA's efforts are random and entropic.
Imagine two couples, each planning to build their own house. The first couple decides what kind of house they want, hires an architect to design it in detail, then acquires the appropriative materials to build it. That is the Apollo Mode. The second couple polls their neighbors each month for different spare house-parts they would like to sell, and buys them all, hoping to eventually accumulate enough stuff to build a house. When their relatives inquire as to why they are accumulating so much junk, they hire an architect to compose a house design that employs all the knick-knacks they have purchased. The house is never built, but an adequate excuse is generated to justify each purchase, thereby avoiding embarrassment. That is the Shuttle Mode.
In today's dollars, NASA average budget from 1961-1973 was about $17 billion per year. This is only 10% more than NASA's current budget. To assess the comparative productivity of the Apollo Mode with the Shuttle Mode, it is therefore useful to compare NASA's accomplishments between 1961-1973 and 1990-2003, as the space agency's total expenditures over these two periods were equal.
Between 1961 and 1973, NASA flew the Mercury, Gemini, Apollo, Skylab, Ranger, Surveyor, and Mariner missions, and did all the development for the Pioneer, Viking, and Voyager missions as well. In addition, t

...it truly is a thing of wonder. Not much biger than your standard NATO round, mine continues to write as it did the day I got it twelve years ago. (Obviously I'm not writing with it all that much, but a true testament to the ink used).
Was that it had 12 different (pressurized) ink color cartridges available. Back before astronauts were just using laptops, they had to color-code their reports. These days, they've dropped some of the stranger colors (e.g. turquoise), but they do make a very cool extra-fine with a tungsten ball, and a bold which is much wider than the average ballpoint. Plus it's nice to have a pen that's small enough to fit into your pants pocket, yet tough enough to sit on and small over and over
Having travelled to India about 20 years ago, that kind of thing remains a strong memory. Coming from the US where we throw away all kinds of things without a second thought, I noticed that a scrap of paper with some empty space on it wasn't thrown away, but reused. And when someone lit a match for their own cigarette, cigarettes appeared from everywhere and that one match would result in maybe 20 lit cigarettes.
