The Solar and Heliospheric Observatory (SOHO) is a European Space Agency (ESA) spacecraft built by a European industrial consortium led by Matra Marconi Space (now Airbus Defence and Space) that was launched on a Lockheed Martin Atlas IIAS launch vehicle on 2 December 1995, to study the Sun. It has also discovered more than 5,000 comets. [2]
Solar and Heliospheric Observatory (SOHO) Sun–Earth L 1: ESA, NASA: Orbiting near L 1 since 1996. Operational as of 2020. [27] WIND: Sun–Earth L 1: NASA: Arrived at L 1 in 2004 with fuel for 60 years. Operational as of 2019. [28] Wilkinson Microwave Anisotropy Probe (WMAP) Sun–Earth L 2: NASA: Arrived at L 2 in 2001.
Solar and heliospheric missions currently located around L 1 include the Solar and Heliospheric Observatory, Wind, Aditya-L1 Mission and the Advanced Composition Explorer. Planned missions include the Interstellar Mapping and Acceleration Probe(IMAP) and the NEO Surveyor. Sun–Earth L 2 is a good spot for space-based observatories.

The next mission to use a halo orbit was Solar and Heliospheric Observatory (SOHO), also a joint ESA/NASA mission to study the Sun, which arrived at Sun–Earth L 1 in 1996. It used an orbit similar to ISEE-3. [5] Although several other missions since then have traveled to Lagrange points, they (eg.

Comet 322P/SOHO, also designated P/1999 R1, P/2003 R5, P/2007 R5, and P/2011 R4, is the first periodic comet to be discovered using the automated telescopes of the SOHO (SOlar and Heliospheric Observatory) spacecraft, and second to be given a numbered designation, after 321P/SOHO.
