Proba-3: Creating artificial Solar Eclipses in space ☀️ #shorts

The double-satellite Proba-3 is the most ambitious member yet of ESA’s Proba family of experimental missions. Two spacecraft will fly together as one, maintaining precise formation down to a single millimetre. One will block out the fiery disc of the Sun for the other, to enable prolonged observations of the Sun’s surrounding atmosphere, or ‘corona’, the source of the solar wind and space weather. Usually, the corona can only be glimpsed for a few minutes during terrestrial total solar eclipses.

Proba-3 aims to reproduce such eclipses for up to six hours at a time, in a highly elliptical orbit taking it more than 60 000 km from Earth. The two spacecraft are being launched together by India’s PSLV-XL launcher from the Satish Dhawan Space Centre.

  1. This is so impressive and interesting! I wonder how this compares to the pros and cons of a fixed coronagraph? Amazed by what the team can do and excited to see what we learn. Thank you to the ESA and the space community for keeping my head up and towards the stars!
