Designing a precision current source for a thermistor measurement system for use on a CubeSat
The Sun is responsible for many radiative processes that are vital to maintaining life on Earth, including the fundamental input of warmth and light to our planet. Yet, the Sun also produces harmful particles and radiation which reach the Earth in the form of space weather. These charged particles c...

The Sun is responsible for many radiative processes that are vital to maintaining life on Earth, including the fundamental input of warmth and light to our planet.

These charged particles can be directed towards the Earth's poles by the Earth's geomagnetic field and cause beautiful phenomena such as the Northern Lights. Much of the harmful radiation is absorbed by the ozone layer in the upper earth's atmosphere, but there are still impacts from the Sun's emissions capable of causing harm, most notably arising from the Sun's coronal magnetic field.
