 in early 2029. More than half a million people including celebrities and politicians participated in the AMFE project, which was the world's first digital time capsule where the content was selected by the public.

As of October 7, 2011 the message has traveled 18.3 trillion miles of the 118 trillion mile trip.

Concept and plan

The idea for the project was raised by Oli Madgett of RDF Digital, who was later put in charge of its implementation. The purpose of the project was to "help capture young people's imaginations and inspire them to think about our own planet earth and humanity's impact upon it". The project was carried out by RDF Digital, a subsidiary of RDF Media Group, in partnership with the social networking site Bebo. RDF Digital originally planned to run the project through a stand-alone website, but later opted for a partnership with Bebo to help it to get more attention and spread the idea quickly.

The main consultant for the AMFE project was Dr. Alexander L. Zaitsev, an expert in interstellar radio communication and Chief Scientist of the Radio Engineering and Electronics Institute of the Russian Academy of Science.

The messages were selected in a competition hosted by Bebo, which more than 12 million Bebo users were invited to join. They were to be selected later through a web vote. An advanced third party application was developed for the AMFE project, which was integrated in Bebo's social network environment. Using this application, its users submitted text messages and pictures and drew images, which were translated into a binary format. Originally, an idea of interstellar radio message composition by the public, which are using special web site, was suggested by Alexander L. Zaitsev in 2002 in his abstract METI@home: Messages to ETI from home.

 away from Earth, and the message would reach the planet in early 2029. The project was funded by advertisements, and the cost of $40,000 was borne by RDF Digital for the transmission which took four and a half hours.

The A Message from Earth mission team in Yevpatoria comprised:
  • Oli Madgett - mission commander
  • Dave Coombs - payload commander
  • Alice Levine - mission specialist
  • James Cooper - mission specialist
  • Jamie Morton - camera man

Competition

The project was launched on August 4, 2008. Bebo invited its users, celebrities and politicians to submit messages and pictures to be included in the digital time capsule. The submissions were expected to "consider the planet from a fresh perspective" and help to raise awareness on environmental pressures on Earth.

A vote was held on a dedicated Bebo page to select the 501 messages that were to be included in the digital time capsule, when its users had submitted their messages. This vote was closed on September 30, 2008 and the 501 messages that had received the most votes were chosen to be included.

Public involvement

More than half a million Bebo users had got involved in the competition for selecting the messages, and had uploaded their messages onto the social networking site. Several celebrities were also involved in the project, including Sir Patrick Moore

Launch and transmission

The launching of the composed message as a digital time capsule took place on 9 October 2008, at 06:00 GMT. The message, containing all selected 501 text messages and images, was translated into a binary format and included in the digital time capsule.
