NASA and ESA operate a fleet of heliophysics satellites at the 'balance point' between the Earth and the Sun, known as Lagrange Point 1, or L1. SOHO, ACE, and Wind have been operating at this point for over 15 years (see SOHO @ 15, ACE @ 15).

SOHO, ACE, and Wind execute 'halo orbits' around L1, between the Sun and the Earth.
