The Question
(Submitted November 14, 1997)
In regards to the Solar Maximum mission, I was wondering if there have
been any similar missions lately.
If not was there a mission or something that was started in 1980 during
February and was continued later and in the present. Or if they were not
continued, was there anything similar?
The Answer
Solar Max was launched in Feb. 1980, and continued operating until it
reentered in December 1989 (except for a few months in 1983-1984, until it
was repaired by Space Shuttle astronauts).

Two space observatories looking at the Sun right now are SOHO and Yohkoh

(one of several Yohkoh instruments)
SOHO is an ESA/NASA collaboration, Yohkoh is Japanese.
