Why Do Astronauts Use Space Pens Instead of Pencils?

by Alex Carter

It's often said that NASA spent millions of dollars developing a pen that could write in zero gravity, while the Russians just used pencils. It was a warning about looking for a high-tech solution to a mundane problem, of American excess vs. Russian sensibility.

It's also entirely false.

To understand why NASA was so keen on a workable space pen, you have to understand that the pencil is not suited for space travel. The problem is that they have a habit of breaking, shattering, and leaving graphite dust behind. The wood, too, can make it a serious fire risk in the pressurized, oxygen-rich capsule. All of these common issues become life-threatening hazards in space.

Still, there were attempts to bring pencils into space. In 1965, the agency famously ordered 34 specially designed mechanical pencils in hopes of finding the perfect writing tool for astronauts. But at $128 each, they weren't exactly cheap, and it only got worse when the public got wind of the price. Thankfully, an alternative was not too far behind.

The Space Pen was invented by Paul Fisher, head of Fisher Pen Company. Unlike a typical pen, the Fisher Space Pen uses compressed nitrogen to force ink out of the nozzle, instead of using gravity to make it flow. This made it the ideal device for writing in space, while upside down, or submerged underwater. It wrote crisp and clean, without the safety concerns of a pencil.

Fisher contacted NASA to give his pens a try in 1965 and in 1967, after months of testing, they were impressed enough to bulk buy 400 of them for future missions. Contrary to those urban legends, NASA didn't commission the pen or contribute any funding to it. The Soviets soon ditched their grease pencils and were eventually buying the same Fisher pens as NASA, too. The price? After a 40 percent discount from Fisher, both space agencies were paying $2.39 a pen.

The Fisher Space Pens made their debut in 1968 on the Apollo 7 mission and have been involved in all manned missions since.

So, the short reason is that astronauts only used pencils when they were waiting for something better to come along. As soon as it did, they switched and never looked back. Even the Russians thought it was a good idea.

Why Do Ants Die After the Queen Dies?

Eduardo Fox:

A fundamental fact about social Hymenoptera (wasps, ants) that most people, including entomologists, are unaware of: They cannot live without their larvae.

Next time you see an ant’s nest, a bee hive, or a hornet’s nest, remember: That structure is essentially a neonatal ICU!

Why? Look at an ant’s body below:


Clker.com via Quora

Did you notice the waist? I tell you: The individual’s stomach is located after the thin waist. That means an ant cannot eat solids.

Now, take a look at an ant’s larva (a & b, below):


Notice the waist? There’s none. It means larvae eat solid food!

So, this is what happens: Ants are working hard together in that nest mainly to bring up hundreds of babies. They come out to get food and bring it back to the nest, then they chew it up and place it on their larvae. Larvae will swallow and digest the food for them. Especially protein. Larvae secrete nutrient-rich liquids back to the ants, which is their main source of amino acids and fatty acids.

Who lays eggs to produce larvae? Queens.*

What happens when queens die? No eggs, hence no larvae.

What happens when there are no larvae? Bad nutrition, ultimately no reason for the nest. Ants gradually get disorganized, and after a few weeks they die.

Wasps and more "primitive" ants can more easily produce a new queen who will be the next mated female in the hierarchy. However, if none of them is fertile enough and mated, the nest won’t last long. Bees work differently.

* Important technical notice: Queens normally live longer than workers. Nowhere in this answer did I mean to imply that larvae can somehow enable workers to live as long as queens!

How Much Is Game of Thrones Author George RR Martin Worth?

Unsurprisingly, Game of Thrones took home another Emmy Award earlier this week for Outstanding Drama Series, which marked the series' third time winning the title. Of course, George RR Martin—the author who wrote the books that inspired the TV show, and the series' executive producer—celebrated the victory alongside ​the GoT cast.

For anyone who may be unfamiliar with Martin's work, he is the author of the A Song of Ice and Fire series, which is the epic fantasy series that led to the Game of Thrones adaptation. Basically, we really we have him to thank for this seven-year roller coaster we've been on.

At 70 years old (his birthday was yesterday, September 20th), Martin has had a fairly lengthy career as an author, consisting of a number of screenplays and TV pilots before A Song of Ice and Fire, which, ​according to Daily Mail he wrote in the spirit of The Lord of the Rings.

Martin sold the rights to his A Song of Ice and Fire series in 2007, and he truly owes the vast majority of his net worth to the success of his novels and the Game of Thrones TV series. So how much exactly is this acclaimed author worth? According to Daily Mail, Martin makes about $15 million annually from the TV show, and another $10 million from his successful literary works.

According to Celebrity Net Worth, that makes Martin's net worth about $65 million.

Regardless of his millions, Martin still lives a fairly modest life, and it's clear he does everything for his love of writing.

We'd like to extend a personal thank you to Martin for creating one of the most exciting and emotionally jarring storylines we've ever experienced.
We wish Game of Thrones could go ​on for 13 seasons, too!
