No. Only a few astronauts have died in the line of duty, and very few (and no Americans) have died in space. The most dangerous part of any space journey is the launch and the landing.
Three American astronauts were killed in a fire in the capsule on the launch pad during testing before Apollo 1. Seven astronauts were killed when space shuttle Challenger was destroyed during launch, and seven astronauts were killed when the shuttle Columbia disintegrated over Texas during re-entry. At least a few astronauts were killed in aircraft accidents.
We believe that the Russians lost a couple of astronauts in space, but this has never been admitted. Several Russian astronauts have died during re-entry or during the landing.

Why doesn't all of the energy from the sun that enters the atmosphere reach the Earth?
Not all of the energy from the sun that enters the atmosphere reaches the Earth because some of it is reflected back into space by clouds, atmospheric particles, and the Earth's surface. Additionally, some of the energy is absorbed and scattered by the atmosphere before reaching the Earth's surface. This results in only a portion of the total solar energy reaching the Earth's surface for use.
