Q: How do I check if I have an active membership?
Visit http://join.marssociety.org and if you don’t automatically see your details, then login with the email you used to register.
Q: I cannot remember my email or password
If you need help logging in, please use the Forgot Password feature or contact our technical support staff using the email webmaster@marssociety.org. We can look up which email address you used to join the Mars Society if you provide other details (name, city/region).
