@KapitaanAli thought you might find this interesting, comparison of the same tracking room at SDSC in the early 80s (for apple sat) compared to recent orbital raising of CY2 today:

Nice blackboard. It's not too shabby for the time though.

when is the ETA landing date?

[Dazzler]

It seems to be moving farther away. Going sunward?

It's do the rotations till the moon's gravity pulls it.

Chandrayaan-2 successfully enters Lunar Transfer Trajectory

The final orbit raising manoeuvre of Chandrayaan-2 spacecraft was successfully carried out today (August 14, 2019) at 02:21 am IST. During this maneuver, the spacecraft's liquid engine was fired for about 1203 seconds. With this, Chandrayaan-2 entered the Lunar Transfer Trajectory. Earlier, the spacecraft’s orbit was progressively increased five times during July 23 to August 06, 2019.

The health of the spacecraft is being continuously monitored from the Mission Operations Complex (MOX) at ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bengaluru with support from Indian Deep Space Network (IDSN) antennas at Byalalu, near Bengaluru. Since its launch on July 22, 2019 by GSLV MkIII-M1 vehicle, all systems onboard Chandrayaan-2 spacecraft are performing normal.

Chandrayaan-2 will approach Moon on August 20, 2019 and the spacecraft's liquid engine will be fired again to insert the spacecraft into a lunar orbit. Following this, there will be further four orbit maneuvers to make the spacecraft enter into its final orbit passing over the lunar poles at a distance of about 100 km from the Moon’s surface.
