98 Read the following article and then choose the sentence that best summarises the main idea.
1 NASA ICG] and the Russian Aerospace Agency wanted to draw attention to space exploration in an unusual way.
2 A space marriage was organized not to put off the ceremony.
3 Russian cosmonaut and his bride wanted to have the strangest wedding ever held.
Some brides worry on their wedding day that the groom won't turn up. But Yekaterina Dmitriyeva arrived at her wedding ceremony knowing that her future husband would not be there, at least not in person. He was, in fact, going to be circling the Earth in a spaceship at that time. But the Russian cosmonaut still got dressed up for the occasion and even had a best man.
Our correspondent reports: "The bride wore a traditional white dress and arrived in a special car, but that's about all that was normal about this wedding as twenty-seven-year-old Yekaterina Dmitriyeva married her sweetheart Yuri Malenchenko. Since the groom was unable to be there in person, guests were greeted by a cardboard cut-out of the forty-one year-old cosmonaut. He's due back from an extended mission on the International Space Station in October, but the couple decided they couldn't wait that long to tie the knot."
The groom's tailcoat and wedding ring were flown out on a cargo ship, a fellow astronaut agreed to be the best man — and with that, the scene was set for the first-ever cosmic wedding, which went ahead via [CG] video-link at NASA's Johnson Space Center in Houston Texas. The bride says that the physical distance in the preparation time was not a problem. But there was some conflict about the wedding. Both NASA and the Russian Aerospace Agency tried to get the couple to wait until Yuri returned to Earth
