Space is not as empty as you think!
While the name suggests that space is empty, that is far from true. Matter released by our sun and space weather events fills the area between our planet and surrounding bodies, and is known as space plasma. Plasma particles are the fourth state of matter (solids, liquids, gasses) and have an effect on how radio transmissions travel through space. It is important for scientists to understand what those effects are. Plasma is always confined by a magnetic field such as the sun's magnetic field, the interplanetary magnetic field or the Earth's magnetic field.
Three projects offer a deeper understanding of the world of space plasma.
A digital upgrade to the South African SuperDARN radar in Antarctica, the construction of a High Frequency Direction Finding (HF/DF) interferometer array, and the tricky business of uncoiling a wire in space will all come together to give SANSA extended capabilities in space weather monitoring and space plasma studies.
