Chandrayaan-3 Update In a significant update on the lunar mission, the Indian spacecraft has entered into lunar orbit after a journey of twenty-three days. As the spacecraft started circling the moon, it began transmitting signals to the Mission Operators Complex (MOX) at the ISRO Telemetry, Tracking and Command Network (ISTRAC). In the present status of the mission, it had included itself into an elliptical orbit around the moon, situated approximately 18,074 km from the lunar surface at its farthest point and 164 km at its nearest, where the mission is aimed at achieving an altitude of 100 km x 100km above the moon’s surface.
On 14 July, the Indian Space Research Organisation (ISRO) launched Chandrayaan-3 – a Moon mission featuring a lunar lander and a rover that will spend 14 days carrying out scientific activities on the surface. In addition to ISRO’s own deep space communication antenna, the mission relies on support from ground stations around the world, coordinated by ESA and NASA. Recently India is trying to 4th country to execute a controlled landing on lunar space Chandrayaan, which means “moon vehicle” in Sanskrit, blasted off from the Satish Dhawan Space Center at Sriharikota in southern Andhra Pradesh state just after 2:30 p.m. local time (5 a.m. ET). On Twitter, ISRO confirmed the Chandrayaan-3 is in “precise orbit” and has “begun its journey on the moon.”They also added that the health of the spacecraft is “normal

Indian Chandrayaan-3 mission
When did Chandrayaan-3 enter moon orbit?
The Indian Space Research Organisation (ISRO) on August 5 completed the Lunar-Orbit Insertion (LOI) to successfully put the Chandrayaan-3 spacecraft into the moon’s orbit. The LOI manoeuvre was performed from ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bengaluru. LOI manoeuvre commenced at 7 p.m.
