Aditya L1: Early on Tuesday, the Indian Space Research Organisation (Isro) announced that Aditya L1, the nation’s first solar mission, has completed the second Earth-bound manoeuvre successfully. The operation was carried out by the Telemetry, Tracking and Command Network (ISTRAC) of the space agency.
Aditya L1’s Second Earth-bound Maneuver Achieved
“The second Earth-bound manoeuvre (EBN#2) is performed successfully from ISTRAC, Bengaluru. ISTRAC/Isro’s ground stations at Mauritius, Bengaluru and Port Blair tracked the satellite during this operation. The new orbit attained is 282 kilometres x 40,225 km,” Isro shared the update on X. According to Isro, the following manoeuvre is planned on September 10 at 2:30 am. The first Earth-bound manoeuvre of Aditya L1 was accomplished on September 3. Before entering the transfer orbit towards the Lagrange point L1 of the Sun-Earth system, which is around 1.5 million kilometres from the Earth, the spacecraft will do two additional earthbound orbital rotations. This position is perfect for solar observation because it offers an uninterrupted and clear view of the Sun.
Aditya L1’s Journey to the L1 Orbit
After roughly 127 days, Aditya L1 is anticipated to reach the intended orbit at the L1 point. On September 2, Aditya L1 was launched from Sriharikota’s Satish Dhawan Space Centre. The Polar Satellite Launch Vehicle (PSLV) in ‘XL’ mode, ISRO’s most dependable and adaptable workhorse rocket, sent the spacecraft, weighing 1,472 kg, into orbit. Studying the Sun’s higher atmospheric layers, specifically the chromosphere and corona, is the main goal of the Aditya L1 mission. Additionally, the mission will look at coronal mass ejections (CMEs), which are significant discharges of plasma and magnetic fields from the Sun’s corona, and assess the corona’s magnetic field, which controls space weather.
Seven Cutting-Edge Payloads Revealed
Seven payloads are carried by Aditya L1, including the Solar Ultraviolet Imaging Telescope (SUIT), the Visible Emission Line Coronagraph (VLEC), the High Energy L1 Orbiting X-ray Spectrometer (HEL1OS), the Solar Low Energy X-ray Spectrometer (SoLEXS), and the High Energy L1 Orbiting X-ray Spectrometer (HEL1OS), which analyse X-ray flares.
