The Sun and Radiation Exposure for Astronauts During Long-Duration Space Flight

While high solar flare activity can expose a spacecraft outside of EarthÂ’s magnetic protection to potentially lethal doses of radiation, astronauts can be shielded against most of this fairly easily. Shielding against much of the GCR, on the other hand, is problematic. Scientists are developing anti-radiation cocktails, mixtures of various substances which can reduce the damage that high radiation doses cause in human cells.

Expansion of the Universe, Edwin Hubble, Astronauts, and the Hubble Space Telescope

The expansion of the Universe is defined by the famous Friedmann Equation.

It is Edwin Hubble for whom the Hubble Space Telescope is named. The space shuttle missions to repair the Hubble Space Telescope was considered more risky than most other space shuttle missions.
