Within the famously competitive group, Glenn had emerged as the 
				face of the space program, while Grissom was reticent in front 
				of the press. When he wrote to his mother, Grissom was still 
				stinging from his Liberty Bell 7 flight on July 21, 1961, that 
				ended with a blown hatch, a sunken space capsule and accusations 
				that the former Air Force fighter pilot had panicked.
"The 
				flight crew for the orbital mission has been picked and I'm not 
				on it," he writes in slanting script, each line of blue ink 
				climbing slightly from left to right on the Project Mercury 
				letterhead. "Of course I've been feeling pretty low for the past 
				few days. All of us are mad because Glenn was picked. But we 
				expressed our views prior to the selection so there isn't much 
				we can do about it but support the flight and the program."
				The letter is being auctioned online by RR Auction of 
				Amherst, N.H., which got it from Grissom's brother, Lowell.
				
				
				"Those original seven Mercury astronauts were extremely 
				competitive people," Lowell Grissom said this week. "If one was 
				picked over another, they all thought it should be them. It's 
				that kind of atmosphere; they all wanted to be first."
				Virgil "Gus" Grissom was the second American to make a 
				suborbital flight. After splashing down in the Atlantic Ocean, 
				his craft sank when the hatch blew open prematurely and it 
				filled with water. Grissom narrowly escaped drowning and 
				insisted until his death in a 1967 Apollo launch pad fire that 
				he did nothing to cause the hatch to blow.
				Glenn became the first American to orbit Earth in February 
				1962 and is the last surviving Mercury 7 astronaut. He did not 
				return calls seeking comment.
				In the Oct. 7 letter to his mother Cecile, Grissom candidly 
				shares his disappointment at being named a flight controller for 
				the second orbital flight, to be piloted by Donald "Deke" 
				Slayton. (Slayton was replaced by Scott Carpenter because of a 
				heart condition.)
				"It's not a job I want," Grissom writes. "I have to do a 
				great deal of the work, I'll be gone from home a lot and I don't 
				get any of the credit, but if anything goes wrong, I'll get a 
				good deal of the blame."
Grissom would later pilot the Gemini III orbital mission.
