Chennai, Sep 15: India’s space-based photo voltaic observatory Aditya-L1 will probably be given a ship off in the direction of the Sun on September 19 when the spacecraft will probably be maneuvered to Trans-Lagrangian Point 1 Insertion (TL1I), the Indian Space Research Organisation (ISRO) stated on Friday.

According to the ISRO, the fourth Earth-bound maneuver was carried out efficiently at 2.15 a.m. on Friday.

“ISRO’s ground stations at Mauritius, Bengaluru, SDSC-SHAR and Port Blair tracked the satellite during this operation, while a transportable terminal currently stationed in the Fiji islands for Aditya-L1 will support post-burn operations,” the house company stated.

According to ISRO, the brand new orbit attained is 256 km x 121973 km.

ISRO stated the subsequent maneuver, Trans-Lagrangian Point 1 Insertion (TL1I) — a send-off from the Earth — is scheduled for September 19 at round 2 a.m.

The Aditya-L1 is India’s house based mostly photo voltaic observatory which was orbited in low earth orbit (LEO) September 2 by an Indian rocket referred to as Polar Satellite Launch Vehicle–XL (PSLV-XL) variant.

The spacecraft’s orbit has been raised by ISRO 4 instances since then.

As the spacecraft travels in the direction of Lagrange Point (L1), it’s going to exit the earth’s gravitational Sphere of Influence (SOI).

After exit from SOI, the cruise part will begin and subsequently the spacecraft will probably be injected into a big halo orbit across the L1 — the purpose the place the gravitational pull of two giant our bodies – Sun and Earth – will probably be equal and therefore the spacecraft is not going to gravitate in the direction of any one of many planet.

The complete journey time from launch to L1 would take about 4 months for Aditya-L1 and the gap will probably be about 1.5 million km from the Earth.
