Chandrayaan 3 lander and rover, India's lunar mission to replace Chandrayaan 2's lander/rover Options

According to the BBC, ISRO tweeted that "the health of the spacecraft is normal". Can't currently source this.

ESA states that its ground station in Kourou will begin tracking the spacecraft as it rises above the horizon in French Guiana tomorrow morning (CEST), 15 July.

The Indian Space Research Organization has confirmed that Chandrayaan-3 is in “precise orbit” and that the health of the spacecraft is “normal”.

About 3 hours after launch ISRO Chairman S Somanath stated: "The Chandrayaan-3 will be injected into lunar trajectory on August 1.” (after 5 or so orbits of Earth)

And: "If everything goes normal then landing on the moon is expected on August 23 at around 5.47pm IST." (12.17 UTC)

A few minutes ago ISRO gave a new Chandrayaan-3 Mission update:

The first orbit-raising maneuver (Earthbound firing-1) is successfully performed at ISTRAC/ISRO, Bengaluru.
Spacecraft is now in 41762 km x 173 km orbit.

The spacecraft's health is normal.

Several interesting data can be found in ISRO's Chandrayaan 3 details page.

For instance, the prime landing site is given as "4 km x 2.4 km [centered on, presumably] 69.367621 S, 32.348126 E"

Chandrayaan-3 has successfully performed the first of its five planned orbit raising manoeuvres, raising the apogee of its orbit from 36,307 km to 41,762 km.

Here are some images of the site listed as prime (please see my previous post). I roughly superimposed part of the LROC image M1421908349L on Google Earth (Moon).

The second orbit-raising maneuver (Earth-bound apogee firing) is performed successfully.
The spacecraft is now in 41603 km x 226 km orbit.
The next firing is planned for tomorrow between 2 and 3 pm IST.

Acquisition of signal from #Chandrayaan3 after a minor perigee raising burn during the preceding apogee. The burn raised the perigee slightly, likely to reduce the effects of atmospheric drag over the weeks to come on the orbit.

ISRO has not published orbit raising plan like previous time. Fan made infographics being shared around are bit misleading.

The mission website is counting down days to the landing. This is a more informative website than I have seen for previous ISRO missions, though my experience is very limited.

Chandrayaan-3 Mission:
The orbit-raising maneuver (Earth-bound perigee firing) is performed successfully from ISTRAC/ISRO, Bengaluru.
The spacecraft is expected to attain an orbit of 127609 km x 236 km. The achieved orbit will be confirmed after the observations.
The next firing, the TransLunar Injection (TLI), is planned for August 1, 2023, between 12 midnight and 1 am IST.
