Talk:Grissom

I find it far more likely that the system was named for Virgil "Gus" Grissom, the second American into space and one of the first American astronauts to be killed in the line of duty (Apollo 1). Two of the other systems in the Armstrong Cluster are named for pioneering cosmonauts (Yuri Gagarin and Valentina Tereshkova) and the cluster itself is named for Neil Armstrong.
