Thank you for your interest and support in becoming a Mars Society member. Remember, your membership allows you to attend our annual convention at a discounted rate. Currently, The Mars Quarterly magazine is available for free to members.  

PayPal will ask you for a shipping address and we will use that for your membership registration. Nothing will be sent to you by mail to confirm your membership. We will instead email you a confirmation. Also, if you have any special instructions for us regarding your membership, please leave them in the "leave the seller a special note" section of your PayPal checkout.  

Thank you,
Mars Society Staff
