What is SOHO NASA?
Launched in December 1995, the joint NASA-ESA Solar & Heliospheric Observatory mission — SOHO — was designed to study the Sun inside out, from its internal structure, to the extensive outer atmosphere, to the solar wind that it blows across the solar system.
Is SOHO spacecraft still active?
Originally planned as a two-year mission, SOHO continues to operate after over 25 years in space; the mission has been extended until the end of 2025, subject to review and confirmation by ESA’s Science Programme Committee.
Where is SOHO spacecraft?
Scientists would place the $1.27 billion SOHO in an orbit around the Lagrange L1 point — an area in space where the gravity of the sun and the Earth balance each other out. SOHO launched Dec. 2, 1995, from Cape Canaveral, riding an Atlas II rocket.

What is unique about the SOHO project?
Over those two decades in space, SOHO has made many new discoveries, adding to scientists’ understanding of our closest star. SOHO has revealed the first images ever of the Sun’s convection zone — its turbulent upper layer of the interior — and of the structure of sunspots below the surface.
Who launched the SOHO?
American Atlas-Centaur
The ESA/NASA Solar and Heliospheric Observatory (SOHO), launched by the American Atlas-Centaur in 1995, orbits about the L1 Lagrangian libration point 1.5 million km sunward from the Earth, where its 14 instruments continuously observe phenomena relevant to understanding the solar interior, the solar atmosphere, and …

How did SoHo get its name?
The name “SoHo” derives from the area being “South of Houston Street”, and was coined in 1962 by Chester Rapkin, an urban planner and author of The South Houston Industrial Area study, also known as the “Rapkin Report”. The name also recalls Soho, an area in London’s West End.
Why is SOHO important?
SOHO monitors the effects of space weather on our planet, and it plays a vital role in forecasting potentially dangerous solar storms. SOHO is the most prolific discoverer of comets in astronomical history, with more than 3,000 tracked during encounters with the Sun.
