Aditya-L1 — India's Solar Observatory at L1
Aditya-L1 is the ISRO spacecraft that serves as India's first solar observatory in space, watching the Sun without a break since January 2024 from a halo orbit around the Sun-Earth L1 point, roughly 1.5 million km from Earth. It is in the news because a study built on its main instrument, the VELC coronagraph, found that a solar eruption swelled lopsidedly instead of as a neat sphere, which matters for forecasting when solar storms reach Earth.

Creates the Aditya-L1 card: launch, L1 halo orbit, seven payloads, and the VELC finding that a solar eruption expanded asymmetrically, which shapes space-weather forecasts.
