Simba CubeSat to swivel from Earth to sun to help track climate change

Due to launch aboard Friday's Vega rocket, ESA's Simba CubeSat is a tiny mission with a big ambition: to measure one of the fundamental drivers of climate change in a new way. The 30-cm long nanosatellite will turn from Earth to space to the sun and back again, to calculate our planet's overall energy budget.
