I dont know but im pretty sure a lot
John Glenn has never been to Mars, nor has any other human being.
John Glenn was the first American to orbit the earth. The previous US flights had been sub-orbital. Yuri Gagarin of the USSR had earlier been the first human to orbit earth.
John Glenn's flight in 1962 made him the first American to orbit the Earth, while Alan Shepard's flight in 1961 was a suborbital flight, meaning he went up and came straight back down. Glenn's flight lasted longer and was more complex than Shepard's.
There have been no human space missions to Mars. The only missions to Mars to date have been through flybys with space craft, orbiters, and land rovers.
The Mercury missions were the first manned missions by the US into space. In a series of sub-orbital and orbital flights, they investigated the effects on humans of space travel and explored many of the unknown orbital and engineering mechanics. The first American in space, Alan Shepard, and the first American to orbit the earth, John Glenn, were the most visible accomplishments of the project. They were followed by the Gemini missions, the curtain raiser to the Apollo moon landings. See the Web Links to the left for further information.
all the missions have been succsessful i completed all of them thank you
save the rest of the towns.
John Glenn never went to the moon. He was the first US astronaut to orbit the earth in 1962 and has been a US Senator.
Yes, in Medal of Honor (2010), single-player missions can be replayed on the same, lower or higher difficulty when they have been completed.
It will be because you haven't completed enough missions yet. After the mission 'blow your cover' has been completed(about 30 missions in)all bridges leading to algonquin(including broker bridge) will open up.
John Glenn orbited the earth three times oFebruary 20, 1962 becoming the third American in space and the first American to orbit the Earth.
have been completed

John Glenn, who had been in the Senate for 9 years in 1984, did seek the Democratic nomination to run against incumbent Ronald Reagan, but he was unsuccessful and the nomination went to Walter Mondale. Mondale had been Vice President under Jimmy Carter, and (like Carter) lost to Reagan.
India has launched 56 satellites into space to date. Many of which have since completed their missions and are no longer operational, some have been landed.
