Summary:

- The European Space Agency (ESA) is planning a twin satellite mission that aims to create on-demand total solar eclipses. The satellites would work together to temporarily block the sun's light, allowing researchers to study the sun's corona and other solar phenomena.
- The mission, called Lagrange, would involve two satellites positioned at specific points in space to precisely align and eclipse the sun from the perspective of Earth. This would provide scientists with controlled conditions to study the sun's outer atmosphere and test new solar observation technologies.
- The Lagrange mission is still in the proposal stage, but if approved, it could launch as early as 2028. The ability to create artificial solar eclipses on demand would be a significant advancement in solar research, allowing for more frequent and targeted observations of the sun's behavior.
