[简答题]
United States Senator John Glenn returned to orbit aboard the space shuttle Discovery in late October, 1998, 36 years after his first lift-off from Cape Canaveral in Florida. (46) The 77-year-old politician, who in 1962 became America’s first man to orbit the Earth, blasted off with six other astronauts on a mission that would include research into ageing. Taking leave of him at the space center along with 3,000 media representatives, 20,000 invited guests and an estimated half million people who crowded vantage points round about to watch the launch-- were his wife of more than 50 years, Annie, his two children and two grandchildren.
Glenn fever struck Florida’s space coast months ahead of the launch, with hotel rooms booked up half a year in advance. One local newspaper called the phenomenon "Hurricane Glenn", an ironic reference to the spate of devastating hurricane that had already hit the Florida coast during 1998.
