Beginning next year, Japanese spouses will have their love vows stored in space after buying platinum wedding rings. The move is an initiative of the Japanese arm of Platinum Guild International (PGI), a body that advocates the use of precious metal jewels, in its campaign to promote platinum wedding rings.

Reuters quotes a Japanese PGI official saying, "People do not link platinum with wedding rings the way they used to." The switch in customs is the new trend with Japanese couples, many of whom prefer simple weddings. In the past, platinum was the metal of choice among Japanese couples.

The promotion allows couples who buy a platinum wedding ring at stores involved in the promotion from August to December this year to write their vows of love on a campaign website.

All these messages accompanied with the pictures of the couples will be stored on a DVD. And a Soyuz rocket, is scheduled to to transport the heartfelt messages into space sometime next year.
