Answer: European Space Agency (ESA)
Notes: The European Space Agency's (ESA) Proba-3 mission is scheduled to launch in September 2024, using India's Polar Satellite Launch Vehicle (PSLV). The mission will see two satellites fly together in space, 144 meters apart, and aligned with the sun. The satellites will block each other's solar disk, allowing researchers to see the sun's faint corona, or surrounding atmosphere. This will be the first precision formation flying mission in the world.
