New oceans beckon for solar sail technology
..., the sail and the ship derive their thrust by reflecting solar photons. It is a common misperception that solar sails use the solar wind for propulsion. This is incorrect. The solar wind is composed of atoms, typically hydrogen and helium, and their...

Solar superstorms and their effects on Earth
... storms and ionospheric disturbance, some of which have now taken place. They include securing a dedicated, operational solar-wind monitoring spacecraft stationed between Sun and Earth, at a distance of 1.5 million km. This was achieved with the Deep...

Protecting against the dangers of space radiation
... placing some of SCK CEN/DLR radiation detectors inside a Colombus module on the ISS. Radiation carried by the solar wind is considered to be low hazard. It produces a constant flux of low energy electrons, protons and alpha particles which are...
