The Reason 2026 Is Set to Be an Unprecedented Year for India's Sun Mission

Regarding India's first solar observatory, 2026 is expected to be like no other.

This marks the initial occasion the spacecraft – which was placed into space last year – will be able to watch the Sun when it reaches its maximum activity cycle.

As per research, this occurs roughly once every 11 years as the Sun's magnetic poles flip – a similar Earth scenario would be the North and South poles changing places.

It's a time marked by intense activity. It sees the Sun transition from calm to stormy and features a huge increase in the frequency of solar eruptions and massive solar flares – massive bubbles of fire that blow out from the solar corona.

Made up of charged particles, a coronal mass ejection may have a mass of billions of tons and can attain velocities exceeding 2,000 miles per second. It can head out in any direction, including towards the Earth. At top speed, the journey takes an ejection about half a day to traverse the 150 million km Earth-Sun distance.

"In the normal or quiet periods, the Sun launches a few solar eruptions daily," explains a leading scientist. "In 2026, we expect there will be 10 or more daily."

Researching coronal mass ejections ranks among the most important research goals of India's maiden solar mission. Firstly, because the ejections offer a chance to learn about the star in the center of our solar system, and two, because activities occurring on the solar surface endanger infrastructure on Earth and in space.

Impacts on Our Planet and Orbital Systems

CMEs seldom present immediate danger to people, but they do affect our planet through generating magnetic disturbances affecting the weather in Earth's vicinity, where about thousands of spacecraft, comprising many from India, orbit.

"The most spectacular displays from solar eruptions are auroras, which are a clear example that charged particles from Sun journey to Earth," the scientist clarifies.

"But they can also make all the electronics on a satellite fail, knock down electrical networks and disrupt meteorological and telecom spacecraft."

Historical Solar Incidents

• The strongest solar event ever recorded was the 1859 solar superstorm which knocked out telegraph lines across the globe
• In 1989, a part of Quebec's power grid failed, leaving millions without power for nine hours
• During late 2015, solar activity disturbed flight operations, causing disruption across Scandinavia and some other European air hubs
• Recently in 2022, an ejection caused 38 commercial satellites failing

With capability to see what happens on the Sun's corona and spot solar activity or solar eruption as it happens, measure its heat at origin and track its path, this serves as advanced warning to switch off power grids and satellites redirecting them out of harm's way.

The Mission's Unique Advantage

There are other solar missions observing the Sun, Aditya-L1 holds an edge over others when it comes to studying the solar atmosphere.

"Aditya-L1's coronagraph has perfect dimensions that lets it effectively simulate lunar coverage, fully covering the solar disk and allowing it an uninterrupted view of nearly the entire of the corona around the clock, throughout the year, including during eclipses and occultations," notes the researcher.

Essentially, this instrument functions as an artificial Moon, blocking the solar glare allowing researchers continuously observe its faint outer corona – a feat the real Moon does only during eclipses.

Additionally, it's unique that can study eruptions in visible light, enabling it to determine eruption heat and thermal output – crucial data that show how strong of an eruption if it headed our direction.

Readiness for Peak Period

To prepare for next year's peak solar activity period, scientists worked together analyzing information gathered from a major solar eruption recorded by the mission has observed recently.

This event began in September 2024 during early hours. The eruption's weight was 270 million tonnes – the iceberg that struck the ship weighed much less.

At origin, its temperature reached extreme levels and the energy content was equivalent to millions of tons of TNT – in comparison the atomic bombs used in Japan were much smaller in scale each.

Although the numbers make it sound incredibly large, the scientist describes it as a moderate event.

The space rock that eliminated the dinosaurs on our planet was 100 million megatons and during solar peak occurs, we could see eruptions with energy content matching even more than that.

"In my view the CME we evaluated happened when the Sun was in the normal activity phase. This establishes the standard for future comparison assessing what is in store during solar maximum arrives," he says.

"The learnings gained will help us developing protective measures to implement to protect spacecraft in near space. Additionally, they'll aid us gain a better understanding of our space environment," he concludes.
