Polar Satellite Launch Vehicle (PSLV) to launch the Aditya-L1 spacecraft on September 2

At the Satish Dhawan Space Centre in Sriharikota, the countdown has begun for the launch of Aditya-L1, India's first solar observatory mission. The ISRO announced on X (previously Twitter) that "the countdown leading to the launch at 11:50 Hrs. IST on September 2, 2023 has commended." The Polar Satellite Launch Vehicle (PSLV) is slated to launch the Aditya-L1 spacecraft, on September 2, 2023, at 11:50 a.m. from Sriharikota, This is the 25th mission for the PSLV-XL variant and the 59th flight of the PSLV overall.

The PSLV will launch the Aditya-L1 spacecraft into an extremely elongated orbit around the planet. The spacecraft will be positioned in a halo orbit around the sun-earth system's Lagrange point 1, or L1, which is around 1.5 million kilometres from the earth. In order to comprehend the issue of coronal heating, coronal mass ejection, pre-flare and flare activities and their features, dynamics of space weather, propagation of particles and fields, etc., the Aditya-L1 payloads are anticipated to offer the most important information.

Visible Emission Line Coronagraph (VELC), Solar Ultraviolet Imaging Telescope (SUIT), Solar Low Energy X-ray Spectrometer (SoLEXS), High Energy L1 Orbiting X-ray Spectrometer (HEL1OS), Aditya Solar Wind Particle Experiment (ASPEX), Plasma Analyzer Package For Aditya (PAPA), and Advanced Tri-axial High Resolution Digital Magnetometers are the seven payloads onboard the satellite.

Aditya-L1 was launched a few days after India's space agency made history by becoming the fourth nation to successfully land on the moon and the first to do so close to the lunar south pole.
