Race for Sun heats up: These are various solar missions
As the Indian Space Research Organisation set to launch its solar mission Aditya-L1 on September 2, following are some important missions launched by space agencies of different countries exploring the Sun:
National Aeronautics and Space Administration (NASA), the US space agency, launched the Parker Solar Probe in August 2018. In December 2021, Parker flew through the Sun's upper atmosphere, the corona, and sampled particles and magnetic fields there. This was the first time ever that a spacecraft touched the Sun, according to NASA's official website.
In February 2020, the NASA joined hands with the European Space Agency (ESA) and launched The Solar Orbiter to collect data to find out how the Sun created and controlled the constantly changing space environment throughout the solar system.
Other active solar missions by the NASA are Advanced Composition Explorer launched in August, 1997; Solar Terrestrial Relations Observatory in October, 2006; Solar Dynamics Observatory in February, 2010; and Interface Region Imaging Spectrograph launched in June, 2013.
Also, in December, 1995, NASA, ESA and JAXA (Japan Aerospace Exploration Agency) jointly launched the Solar and Heliospheric Observatory (SOHO).
JAXA, the Japan's space agency, launched its first solar observation satellite, Hinotori (ASTRO-A), in 1981. The objective was to study solar flares using hard X-rays, according to JAXA's official website.
JAXA's other solar exploratory missions are Yohkoh (SOLAR-A) launched in 1991; SOHO (along with NASA and ESA) in 1995; and Transient Region and Coronal Explorer (TRACE), along with NASA, in 1998.
In 2006, Hinode (SOLAR-B) was launched, which was the successor to Yohkoh (SOLAR-A), the orbiting solar observatory. Japan launched it in
