  The Aditya-L1 is the first space-based solar observatory of the Indian Space
Research Organization (ISRO). The spacecraft will carry seven payloads
providing uninterrupted observations of the Sun from the first Lagrangian
point. Aditya-L1 comprises four remote sensing instruments, {\it viz.} a
coronagraph observing in visible and infrared, a full disk imager in Near
Ultra-Violet (NUV), and two full-sun integrated spectrometers in soft X-ray and
hard X-ray. In addition, there are three instruments for in-situ measurements,
including a magnetometer, to study the magnetic field variations during
energetic events. Aditya-L1 is truly a mission for multi-messenger solar
astronomy from space that will provide comprehensive observations of the Sun
across the electromagnetic spectrum and in-situ measurements in a broad range
of energy, including magnetic field measurements at L1.
