[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.
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 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.

Coverage of the launch is expected to begin at 11 a.m. ET and will be added to this story in the video player above. The launch window itself is set to open at 12:06 p.m. ET.
Mission: investigating Jupiter and Saturn, and the moons of these planets. Its continuing data feed offered the first direct measurements of the heliosheath and the heliopause . It is currently the furthest man-made object from Earth, as well as the first object to leave the heliosphere and cross into interstellar space .
The Goldstone Solar System Radar (GSSR) is a large radar system used for investigating objects in the Solar System.Located in the desert near Barstow, California, it comprises a 500-kW X-band (8500 MHz) transmitter and a low-noise receiver on the 70-m DSS 14 antenna at the Goldstone Deep Space Communications Complex.
