Under Pressure!!

The ArianeGroup fueling team have done an amazing job testing both satellites and filling the OSC with 268 bar of nitrogen for flight. The CSC was pressurised to MEOP to allow leak testing to be performed.

PSLV-C59 // Proba-3 Updates:

The Proba-3 stack and the PS4 stage have been encapsulated within PSLV's fairing!! 🔥

Next, the Mobile Service Tower (MST) will retreat, leaving PSLV-C59 out on the First Launch Pad awaiting launch! 🚀

✨ Just 3 days to go!
The trusted PSLV is ready to shine with the PSLV-C59/PROBA-3, a mission by NSIL enabled by ISRO, in collaboration with ESA.
🚀 This mission will place ESA’s PROBA-3 satellites (~550kg) into a unique highly elliptical orbit, reinforcing PSLV’s reliability for complex orbital deliveries.
💡 Orbit Highlights:
Apogee: 60,530 km
Perigee: 600 km
Inclination: 59°
Semi-major axis: 36,943.14 km
📅 Liftoff: 4th Dec 2024, 16:08 IST
📍 Location: SDSC SHAR, Sriharikota
Stay tuned for updates from NSIL, ISRO, and ESA as the countdown continues! 🌌

That one will launch on the PSLV-C60/SPADEX mission later this month.

Re indian satellite going up with Proba

This article indicates that it will be launched on PSLV-59 with Proba. Could be inaccurate

Proba-3 encapsulated
02/12/2024

The double-satellite Proba-3 stack and their upper stage were encapsulated within their launcher fairing on 29 November. The last red tag and green tag items were removed/installed and the team took a final look at their mission with their own eyes. Proba-3 is due to launch on a PSLV-XL launcher at the SHAR base of the Indian Space Research Organisation, ISRO, on 4 December.

ESA’s twin Proba-3 platforms will perform precise formation flying down to a single millimetre, as if they were one single giant spacecraft. To demonstrate their degree of control, the pair will produce artificial solar eclipses in orbit, giving prolonged views of the Sun’s ghostly surrounding atmosphere, the corona.

Due to an anomaly detected in PROBA-3 spacecraft PSLV-C59/PROBA-3 launch rescheduled to tomorrow at 16:12 hours.

As per the ESA's request, the launch of PSLV-C59/PROBA-3 has been rescheduled as follows:

Date: 05th December 2024
Time: 16:04

During Proba3’s pre-launch preparations at the Satish Dhawan Space Centre in India, an anomaly in the redundant propulsion system of the Coronagraph Spacecraft occurred. This propulsion system is part of the attitude and orbit control subsystem of the satellite and used to maintain orientation and pointing in space.

The anomaly is currently under detailed investigation. The use of a software solution by the mission control team at @ESA’s ESEC centre at Redu, Belgium is being evaluated to allow a launch on Thursday 5 December at 11:34 CET (10:34 GMT, 16:04 local time). #Proba3
