    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.

    Mimicking a Solar Eclipse in space

    During a solar eclipse the Earth is plunged into darkness and the Sun’s ghostly atmosphere becomes visible. Scientists travel the globe to experience total solar eclipses, which occur for just a few minutes at a time every 18 months or so. But what exactly causes solar eclipses, and how do scientists try to make their own, including with ESA’s new Proba-3 mission?

    00:33 – 01:45 – How do solar eclipses happen?
    01:46 – 02:45 – How do we know anything about the solar corona given that eclipses occur so rarely?
    02:46 – 04:00 – How can we create a perfect artificial solar eclipse in space?
