National Geographic’s online shop has lots of holiday discount specials, including my book, MARS: OUR FUTURE ON THE RED PLANET.

Also, stay tuned in 2018 for season 2 of Mars on the National Geographic channel.

 

For a sneak peek at all things Mars that requires further investigation and consideration, go to:

https://shop.nationalgeographic.com/product/space-collection/mars

Or try this link –

https://shop.nationalgeographic.com

and search for the book – “Mars: Our Future on the Red Planet”

As I post this, it’s selling for $21 on their site, rather than the cover price of $30. That’s about the same price as on Amazon.com – or support your local book store who might have specials too.

Thanks for your inquires and interest!
