John Glenn, who made history twice as the first American to orbit the Earth and the first senior citizen to venture into space, died on Thursday at the age of 95.
The US space agency Nasa was among the first to pay tribute to the legendary astronaut who went on to serve in the Senate for more than two decades, calling him “a true American hero”.
“Godspeed, John Glenn. Ad astra,” Nasa tweeted.
Glenn died at the James Cancer Hospital in Columbus, Ohio, according to Hank Wilson, a spokesman for the John Glenn College of Public Affairs. The cause of death was not immediately given.
“With John’s passing, our nation has lost an icon and Michelle and I have lost a friend,” US President Barack Obama said in a statement.
“When John Glenn blasted off from Cape Canaveral atop an Atlas rocket in 1962, he lifted the hopes of a nation.”
The astronaut and veteran of two wars had been in declining health, undergoing heart-valve replacement surgery in 2014 and reportedly suffering a stroke, and was admitted to the cancer ward in Columbus more than a week ago.
