Scientists in India have recently unveiled a "first significant result" from the Aditya-L1 mission, the nation’s inaugural solar observation project in space. Launched with seven advanced scientific instruments, the most notable among them is the Visible Emission Line Coronagraph (Velc), which captured vital data on a coronal mass ejection (CME) on July 16.

Coronal mass ejections are colossal plasma eruptions from the sun's corona, capable of unleashing energy equivalent to billions of atomic bombs. Weighing up to a trillion kilograms and speeding towards Earth at 3,000 kilometers (1,864 miles) per second, CMEs can disrupt electronic devices and power grids on our planet.

Professor R. Ramesh from the Indian Institute of Astrophysics, who is also the principal investigator of Velc, detailed that the CME they studied originated on the side of the Earth at precisely 13:08 GMT. Luckily, this specific ejection was deflected away from Earth, sparing us from its repercussions. However, more potent solar storms pose serious threats not only to terrestrial infrastructure but also to the approximately 7,800 satellites orbiting our planet.

According to experts from Space.com, while the immediate risk to human life from these solar phenomena is low, they can wreak havoc by interfering with our magnetic field, leading to disruptions in communications, GPS navigation, and other satellite-dependent technologies. For instance, the historical Carrington Event of 1859 crippled telegraph systems globally and created spectacular auroras visible even in lower latitudes like London.

In October 2015, an intense solar activity disrupted air traffic control across northern Europe, demonstrating the chaos that solar storms can induce. If scientists can monitor the Sun in real-time via missions like Aditya-L1 and predict the trajectory of such ejections, there is potential to mitigate these effects by temporarily shutting down vulnerable electrical systems and satellites.

Agencies like NASA and the European Space Agency (ESA), along with counterparts in Japan and China, have spent years observing solar activities through various missions. By joining this elite group, India's Indian Space Research Organisation (ISRO) launched Aditya-L1 in early 2023, named after the Hindu Sun god, symbolizing its ambition to deepen our understanding of solar dynamics.

Aditya-L1's strategic location enables continuous observation of the Sun, including during solar eclipses when Earth-based observers cannot view the solar corona. This advantage allows Velc to provide uninterrupted insights into the intricacies of solar activity, thus enhancing global knowledge.

According to Professor Ramesh, the precision of India’s coronagraph outmatches some existing technologies. The compact size of Velc allows it to effectively "hide" the Sun’s bright surface, the photosphere, ensuring a clear view of the corona—a feature that is crucial in accurately determining the origins and trajectories of CMEs.

Additionally, India supplements the insights from Aditya-L1 with data from three ground-based observatories across the country, located in Kodaikanal, Gauribidanur, and Udaipur. The combination of these resources will significantly enhance our understanding of solar phenomena, making the Aditya-L1 mission an essential undertaking not just for India, but for the global scientific community.

India's contribution to solar research is poised to forge new paths in our quest to harness the power of the Sun, improving readiness for solar storms while enriching our understanding of the solar system as a whole. Stay tuned for more revelations from this groundbreaking mission!
