They actually don't die, if you read the book series, Master Chief goes back to reach after the events at Halo and finds out that about 5 of them survived (the ones on the poster?), plus the one that he saved in space (which was actually on Halo with him!) After they are rescued they go back to Earth, with the exception of one Spartan, who was kidnapped by Dr. Halsley (the one who created the Spartan-II's.)
In the next book, Ghost of Onyx, we find out that another one of the Spartans, believed to be dead, was actually training new Spartan-III's. The planet Onyx, which they were training on, was soon attacked by the Sentinels, and later the Covenant. I don't want to give away the story, but many of the Spartans are still alive, and are residing in a shield that is strong enough to block the Halo attacks.
