The Autumn Equinox 2013 issue of The Planetary Report is out!

Topics: The Planetary Report

At last, it’s here! The autumn equinox issue of The Planetary Report is in the mail. I apologize for its lateness and I thank you for your patience. I think you’ll find the end result to be worth the wait.

For our Members who choose to receive their magazine electronically, you can pick it up here.

Giant polygonal features have been visible on the surface of Mars since the 1970s—they were first seen in images returned by the Mariner 9 and Viking orbiters. These features are common in Mars’ northern lowlands—where its ancient oceans likely would have been. The polygons origins, however, have continued to mystify scientists. Here, Dorothy Oehler details the processes that may have led to their formation and she compares them to similar, smaller, polygons on Earth.

It’s not just passion and money that fuel space exploration. How about radioactive decay? Plutonium-238 (Pu-238) has powered nearly 30 deep-space missions in NASA’s history. But in 1988, the United States stopped production, and remaining supplies are nearly gone. In “Power from the Isotopes,” Casey Dreier explains why the U.S. stopped making Pu-238, why we have a shortage, what is being done about it, and what had to happen to restart Pu-238 production in this country.

In addition, Bruce Betts describes upgrades to our search for new planets and ET, we gain some insight into Ganymede’s underground ocean, and Bill Nye gives us a tasty lesson on how cooling lava cracks—with cookies!

The Planetary Society exists and does great work because of you. We aim to change the world. If you are not yet a Member and would like to be a part of our team, just go here to buy a year’s membership. To thank you, we’ll give you four issues of The Planetary Report, a magazine in a class by itself.

How do I continue to get the Kids section in my Planetary Report?

Michael Peterson: 11/18/2013 09:52 CST

At the age of 58, I finally started to extensively study a subject which had interested me for a long time. Basic cosmology was a subject which I became to study with relish. As my interest grew, from the basic formation of stars, it soon led to more intense issues, such as relativity, string theory, M-theory. Soon quantum mechanics started creeping into the mix. Space exploration, and planetary cycles became more interesting, as the foundation of my knowledge to such things as novas, super novas, and black holes increased. To see these things in imagines to balance text book theories only increased my fascination Today with a bigger understanding of the cosmos, I have an interest on nearly any subject relating to our solar system and the universe at large. Any information on space exploration will be eagerly read. The list of research vessels soon to be launched will no doubt give even people like me a chance to see the wonders in space. Even more important, is the information that can be found to make a better, and even safer life here on mother Earth.

Joseph and Susan: Thank you for your request. To continue to receive Planetary Kids, just send an email to, or call us at (626) 793-5100. We will no longer bind Planetary Kids into the magazine (not practical unless it's going out to everyone), but we will mail it separately to all Members who request it.

I have been a member sir several years and will be a member for many more. I love learning more about our solar system, and appreciate all you do.

Vish Kurup: 12/04/2013 11:37 CST

Some more on the efforts made by other lesser space organisations would also be welcome.This magazine is truly a great one and I am very happy to have joined the Planetary society.

Humans may be the evolutionary link to intelligent super computer based robots. They could populate the universe and live on solar power on planets where we never could. Maybe other civilizations have made them already. Maybe they are nearby?

Panagotis Malaspinas: 12/16/2013 08:06 CST

the question is can we put a distance were reality for us as human beings stops in space. we all know the further we go away from our planet the further in time we go. ill go as far to say that if we could travel to our sister galaxy Andramida our reality would not exists any more. yes even if we could move with the speed of light.

It's a great pleasure for me to be a member of planetary society!

Md Islam: 01/20/2014 10:39 CST

I always feel the curiosity to know the most important information about all plannet.

dinna ruiz rodriguez: 01/30/2014 10:29 CST

I want to written my name in yours Project Bennu. Thank you

To all of you at the Planetary Society keep-up the great work. Ten years on Mars is great. After the Apollo Moon program we should have planed our human missions to Mars. We could have a Mars base by now. I will keep my dream alive !!! D.L.
