Untethered Realms Welcomes Alex. J. Cavanaugh


The Realities of Space Travel

Speculative fiction provides us the opportunity to explore beyond our world. Writers get to imagine what’s beyond the edge of our solar system while trying to infuse as much reality as possible. Just what are the realities of space flight though?

Travel time isn’t as fast as portrayed in the movies. We haven’t achieved light speed. Not even close! The space shuttle traveled at a rate of 18,000 mph/29,000 km/h. It can circle the Earth in ninety minutes, but getting all the way to Mars would take over six months. With current technology, it just isn’t going to go much faster.

That leads us to the next reality - ship requirements if we’re to travel farther than the moon. It would take a much larger ship than the space shuttle. It would need to store more supplies, possess a stronger propulsion system, more shielding against radiation, and larger accommodations for the crew. They would also need room to carry equipment for Mars or whatever planet was their destination. They are working on a ship that can travel to Mars, but that’s a lot of things they need to consider when constructing it.

Perhaps the scariest reality is the effect of space travel on the human body. Without gravity, an astronaut’s bones lose minerals at a rate of 1% a month. On earth, the average is a little over 1% per year. Astronauts also experience pressure in their heads and vision problems, along with mental difficulties resulting in depression or sleep disorders. Radiation is a problem–on the space station, humans receive ten times plus the amount of radiation as they would on Earth. This increases the chance of cancer, radiation sickness, and nervous system damage. After six months on the space station, astronaut Scott Kelly’s skin became super-sensitive and he developed a hive-like rash whenever he touched anything. These issues would compound during a long trip, bordering on life-threatening.
 
This is where the freedom of being a speculative fiction writer comes into play. Unless we are writing about current or near-future situations, we can circumvent these issues. We can invent things in our minds that will not only solve these problems but propel us beyond existing projections. Set a story in another solar system or galaxy and we can blow past all imagination. The boundaries of space no longer apply.

We need to be aware of the limitations of today’s space travel, but we don’t have to be confined by them!

Drink & Be Hairy, Scary, Merry?

There are plenty of things in this world to look forward to:

  • The weekend
  • A great movie release
  • Your birthday


The list can go on and on. Instead, I'd like to focus on one of the things that many of us look forward to in different ways...and it isn't just a human or earth thing either...

It's our drinks.

See, most folks look forward to that first cup or three of coffee, cappuccino, or cafe au lait in the morning.

Another drink that some folks look forward to is a nice shot of whiskey. Best be careful, it might put hair on your chest.

Getting supernatural, blood is the drink of choice for those of the vampire persuasion. If one is of the "let's not drink up all the blood of our neighbors" mindset, there's Tru Blood.

If you have a god-like need to quench your thirst, ambrosia is said to give satisfaction and immortality.
If you're ever out on the spaceways, zipping from one planetary system to the other, take a tip from the Hitchhikers Guide to the Galaxy and be careful of the Pan Galactic Gargle Blaster. I understand the effects of this drink can cause you to be merrier than anything or anyone in your wildest imagination.
Mixing instructions
As for me, a nice glass of wine will do.
What about you? Do you have a special drink that you look forward to, perhaps a concoction of your own making that friends enjoy at gatherings, or something that brings that long, exhausting day to a nice closure? Heard of any "out there" drinks of interest?

Please share in the comments :-)
