The scale of Phobosby *Ludo38

Digital Art / Photomanipulation / Sci-Fi

It's been a long time since I wanted to give the scale of Phobos. Here it is, compared to my town, Grenoble, east of France, in the Alpes.

More about this picture on my Mars blog :

I notice you have some images of a Robinson style Mars space elevator. Robinson as well as Clarke note that Mars has an angular velocity similar to earth's (about a 24 hour day). But Mars' gravity well is shallower so the Martian elevator suffers less stress than an earthly elevator would.

For an elevator high angular velocity and shallow gravity wells are desirable. This makes Ceres and Vesta good candidates. Phobos is even better. Here is a graphic comparing a Phobos elevator to a Mars elevator: [link]

Thanks for the insight on the elevator issue. Interesting how deep you go in this area. Did you try to join people who actually work on researchs for making that thing possible ? I guess you visit this blog often : [link]
For my part, even if I like the realistic aspect, I am an artist and then focus on the image work. I'm not at all into physics and don't understand much.

BTW, the KSR.info website just made an update with an infographic I made on Red Mars : [link]
I recommend this website a lot. It's full of informations, articles and conferences links from Robinson.

I hadn't seen the elevator blog, thanks for the link.

I am strictly an interested amateur. However I had sent some of my Phobos elevator illustrations and calculations to Jerome Pearson, a pioneer in elevators. I was amazed he actually replied saying he liked it. He suggested I present a paper at the annual space elevator conference.

I believe artists and writers have a big influence on the collective dreams of the general populace. Norman Spinrad wrote an essay speculating that much of the innovations of the 20th century were inspired by science fiction.

I don't see 21st century science fiction playing this role. The genre has morphed into science fantasy as most space operas now assume faster than light travel. I write about this more at [link]

Kim Stanley Robinson is one of the few modern science fiction writers whose stories are remotely plausible. For that he earns my admiration.

I remember once a big planetarium had a scale model of NYC and the martian moons and some of the first 100 asteroids hovered over it plus a comet nucleus or two. Very graphic demo.

This is even more realistic and fascinating.

Lets just hope nobody sees this kind of thing on Dec 21.

The Grenoble Winter Olympics were the first Olympics I remember watching on TV, as a kid.

*Ludo38 Oct 13, 2012 Professional General Artist

The Olympics would have look much more epic with Phobos over Grenoble !

This is a pretty wicked idea. I love the use of your town to give a perspective of Phobos' size.

*Ludo38 Oct 9, 2012 Professional General Artist

Thanks dude ! I wish I have more time to make hundreds of other cool pictures like that.

*LutherTaylor Oct 8, 2012 Hobbyist Digital Artist

all this picture needs now is a evil face on Phobos and a clock tower in the center of town
