ESA Prepares To Create Solar Eclipses To Study the Sun

Achieving this formation will allow the Coronagraph to study our star's highly ionized, extremely hot atmosphere -- but also demonstrate the technology as a precursor for more ambitious, future, formation-flying endeavors. ESA has science objectives for Proba-3, using observations made in space to study solar astrophysics without any intervention of the Earth's atmosphere. The agency's Association of Spacecraft for Polarimetric and Imaging Investigation of the Corona of the Sun (ASPIICS) coronagraph will help to discern why the solar corona is significantly hotter than the Sun itself. This could further our understanding of the Sun and assist solar weather predictions. However, it is the precision formation flying that Proba-3 aims to demonstrate which could help unlock future breakthroughs. Precisely-controlled Occulter spacecraft could be used with space telescopes to block light from a star in order to directly detect potential orbiting planets, while a constellation of spacecraft can, through interferometry, create large-scale observatories, achieving large apertures and long focal lengths than possible with large solo satellites. Further applications include Earth observation, space-based gravitational wave detection, and a range of missions in which two or more spacecraft need to interact, such as rendezvous, docking, and in-orbit servicing.
