How much would you weigh on an exoplanet?

Kepler 69c
I posted this article on my own site some time ago (2012) and it garnered so much interest I thought it worth repeating for the SFR audience. Yes, there's maths, but it's easy maths because that's the only kind I can do.  Don't believe anybody who tells you a computer programmer has to be able to add up.

++++++++++++++++++

I was reading an article from somebody, all enthusiastic about the exo-planets the Kepler probe keeps finding. They’re all many times larger than planet Earth even if they’re in the ‘Goldilocks’ zone. You know the one – not too close, not too far, just right. That is, a planet neither too close to its primary nor too far away, where liquid water could exist. My immediate reaction was ‘sure, but we’d weigh too much’.
Then I wondered how much more. I’m not a mathematician – never have been. In truth, I can’t add up to save my life. So I’m counting on you (ha ha) to correct me if I get this wrong. Please note that this all assumes that the planet we're talking about is rocky, like Earth and Mars. I can't see us wanting to settle on a place like Jupiter or Neptune any time soon.

I discovered this site http://www.exploratorium.edu/ronh/weight/ and learned that gravitational pull weakens by the radius squared. So let’s say you weighed 60kg on planet Earth. Planet Gliese 581g is estimated at 2.6 Earth masses and 1.4 Earth radii. So yes, you’re going to weigh more on Gliese 581g, but not 2.6 times as much. If I’ve got this right, the increased diameter of the planet means you’ll weigh about 1.3 times as much – so about 78kg. That’s certainly not a huge imposition. And all of a sudden, I’m bouncing in my chair, going oooh oooh.
Here’s some estimated figures about Gliese 581g, taken from this fascinating website http://phl.upr.edu/projects/habitable-exoplanets-catalog

Mass = 2.6 Earth Radius = 1.4 Earth  Temp = average surface temperature, so this place, at 10, is rather cooler than our 15 degrees (NASA’s figure from 2008), but the estimate of average temperature assumes an Earth-like atmosphere, which is a pretty big assumption. On the face of it the planet zips around its sun in a fraction of the time it takes ours, taking only 32 days as compared to 365. But that might not be the case, since the Gliesean day may be much longer than Earth’s. The figures don’t mention period of rotation, which I find a tad surprising. As a comparison, Venus’s ‘day” (the time it takes to rotate on its axis) is actually longer than its year (the time it takes to orbit the Sun.) (http://www.universetoday.com/14282/how-long-is-a-day-on-venus/)

So there you have it. I found out today that a candidate for Torreno (capital of the Coalition of Worlds in Morgan’s Choice) may be only 20.2 light years away. And with the shift drive of the future, that’ll be a place to add to your holiday plans.

Heather Massey Blogs About Steampunk, Gamebooks, and Women in SF&F

I'm cross-posting my latest blogging news from The Galaxy Express:

When it rains, it pours. That's true not only of the weather outside my window, but also three guest posts of mine that all went live today!


Sci-Fi Romance: A New Kind of Hero

At Fantasy Book Cafe, I'm a participant in this year's Women in SF&F month! I'd enjoyed the posts of that event in years past and was delighted when hostess Kristen invited me to contribute an article.

The topic is my love of science fiction romance and how the "...genre has rewritten the hero narrative in order to give female characters leading roles as well as explore love and sex in a science fictional setting."

I presented a number of titles I've enjoyed, and the selection also serves to highlight the sheer variety available in this genre.

Interactive Stories: Past, Present, and Future

Author Ella Drake (DESERT BLADE) kindly provided me with some time at the CONTACT - Infinite Futures podium to blog about gamebooks, a.k.a. "choose your own adventure" type stories.

Given the release of my own interactive science fiction romance DANGEROUS RENDEZVOUS (SilkWords), it was a fun chance to delve into the history of interactive stories as well as contemplate how they might evolve in the future.

The Important Contribution of Finnegan H.H. O'Riordan's Sky Pirate: Safe Harbor

My Coffee Time Romance steampunk romance column this month focuses on a charming story called SKY PIRATES: SAFE HARBOR by Finnegan H.H. O'Riordan. The tale includes airships, automaton action, and steampunk inventions, but also a rare level of diversity in steampunk romance. For that contribution, it deserves a commendation.

Enjoy!

A Wreck of Titanic Proportions in Outer Space

The sinking of the unsinkable luxury liner Titanic has inspired many a book and movie over the 102 years since ship-met-iceberg, including my own "Wreck of the Nebula Dream."  

Aside from the nonfiction accounts and straightforward romance novels set on Titanic, there have been stories featuring everything from time travel to werewolves.  Even Douglas Adams, he of “The Ultimate Hitchhiker’s Guide to the Galaxy” fame wrote a comedic treatment with Terry Jones of Monty Python in the last 1990’s, based on a cd-rom game, odd as that may sound. Reading a synopsis of the book on Amazon, however, the work doesn’t seem to have taken much from Titanic but the name.

Certainly there was nothing humorous about the sinking.

Right from the beginning though, what I wanted to write was a serious novel, set in the far future, on a space-going luxury liner. Originally I thought I’d be able to pretty much follow the pattern of what happened to Titanic for my own plot, somewhat changed to reflect the future and the “ocean of space”, versus the Atlantic.

My characters felt otherwise. I’m a very seat-of-the-pants style novelist and almost as soon as I began figuring out who would be aboard and what catastrophes might occur, I could see I was going to be loosely suggesting Titanic. Actually, that was a freeing realization, because in the 1912 sinking so many people lost their lives and there are relatives and descendants worldwide who are still affected by the ripples from the tragedy. I didn’t want to write anything that might reflect back on the real people who sailed on Titanic.

I kept the situation though – a middle of the night disaster, not enough lifeboats, no lifeboat drill, too much speed, new engines, inability to get help in a timely manner, communications issues…and men, women and children in jeopardy. I gave some nods to well known facets of the Titanic, starting my novel with a scene on board the shuttle, where a female passenger creates a fuss, having had a terrifying premonition of the disaster. In 1912 many people had documented premonitions of disaster and foreboding dreams about Titanic, and about 50 actually cancelled their passage.
 
There’s an entire deck of the Nebula Dream that’s the swimming area, complete with a beach – Titanic had an actual swimming pool, which was considered quite a novelty at the time. I have one rich passenger on my ship searching for her jewels in the damaged hold area, picking up on the theme of the women who tried to retrieve theirs from the Titanic’s purser after the ship struck the iceberg.

Of course, this being science fiction, I threw in some twists and turns abut who or what comes looking for the ship in distress (but no spoilers from me!)….

I’ve always thought it was especially poignant that so many children perished when Titanic sank, so I included Paolo age 8 and Gianna age 3 as two of my characters, representing in my mind all the little ones who didn’t survive in 1912. I made sure my hero Nick,  and every other person in the group, was  devoted to getting the children safely off the Nebula Dream.

Speaking of Nick, when I was thinking about who the hero should be, I asked myself who I’d want there with me if I was in such a perilous situation. A Special Forces soldier sounded about right! Once I figured out why he’d be traveling on such a luxurious vessel, the plot fell into place.  Mara Lyrae,the heroine, is a high powered business executive, who worked her way up from entry level to the heights of intergalactic corporate power, but hasn’t forgotten anything she learned along the way.  She also does not buy into “women and children first” when it comes to herself. She’s in the thick of trying to rescue others. There was at least one business woman on the Titanic, Lady Duff-Gordon for example, who was a well-known fashion designer of her time.

Even I couldn’t ensure that all the passengers survived in the book, any more than everyone survived the Titanic sinking…but there’s a Happily Ever After ending for some people. Because this is a romance after all.

Much as I like writing in seat-of-the-pants style, it soon became apparent I’d better sit down and design my starship, so I’d know which deck had what and could explain to the Readers where Nick and the others were going at any given time. I still have that hand drawn schematic, not that it’s exactly a thing of beauty!  But this was one time I really did have to do the details before the writing.

The story for WRECK OF THE NEBULA DREAM:
2013 SFR Galaxy Award and Laurel Wreath Winner

Traveling unexpectedly aboard the luxury liner Nebula Dream on its maiden voyage across the galaxy, Sectors Special Forces Captain Nick Jameson is ready for ten relaxing days, and hoping to forget his last disastrous mission behind enemy lines. He figures he’ll gamble at the casino, take in the shows, maybe even have a shipboard fling with Mara Lyrae, the beautiful but reserved businesswoman he meets.

All his plans vaporize when the ship suffers a wreck of Titanic proportions. Captain and crew abandon ship, leaving the 8000 passengers stranded without enough lifeboats and drifting unarmed in enemy territory. Aided by Mara, Nick must find a way off the doomed ship for himself and several other innocent people before deadly enemy forces reach them or the ship’s malfunctioning engines finish ticking down to self destruction.

But can Nick conquer the demons from his past that tell him he’ll fail these innocent people just as he failed to save his Special Forces team? Will he outpace his own doubts to win this vital race against time?
