New Carbon-Carbon nozzle for PSLV fourth stage (PS4)
"(…) The PS4, the fourth stage of the PSLV, currently employs twin engines with nozzles made from Columbium alloy. However, by replacing these metallic divergent nozzles with C-C counterparts, a mass reduction of approximately 67% can be achieved. This substitution is projected to increase the payload capability of the PSLV by 15 kg, a notable enhancement for space missions"
Rajasthan: Colleges Hold Ram-Themed Competitions After ISRO Affiliated Organisation’s Letter to CM
In its circular, the Rajasthan Department of College Education has urged all government college principals to comply with India Space Week's letter asking for Ram-themed competitions.
So we have a new render of JAXA/ISRO Lunar Polar Exploration mission (LuPEx) spacecraft stack which will be launched by H3 (24L variant)
Propulsion Module + Lander Module + Rover (weighing ~6,500 kg)
• Precursor mission to ISRO's Lunar Sample return mission.
• Pre Phase-A and Phase-A feasibility studies completed
• Lander configuration finalized and under review process.
Some #murals outside the #ISRO#museum or Vikram Sarabhai #Space Exhibition Center. More than the space stuff, enjoyed the #mural(s) painted on the walls.

‘No salaries in last 18 months’: Workers who made parts for ISRO satellite launches stage protest
Employees of the government-owned Heavy Engineering Corporation say they have been struggling to make ends meet. On September 17, BBC Hindi had reported that some employees of the Heavy Engineering Corporation who contributed in building a launchpad for the Indian Space Research Organisation had taken up odd jobs, including selling idlis, tea and momos, by the roadside in Ranchi.
All eyes are now on the moon again as the sun rises over India's Chandrayaan-3 lander and rover. The solar panels should be receiving sufficient solar energy by tomorrow. What remains to be seen is whether Chandrayaan-3 and its electronic systems survived the below --150°C lunar temps over the 2-week lunar night. Hopefully, some subsystems, if not all, did.
Sun elevation should be around 5° at this time (Sep 21 00:00 UTC) and increase to 9° in the next 24 hours.
Note that since the moon does not have an atmosphere, the low elevation angle of the sun does not much affect the intensity of solar radiation at the Chandrayaan-3 site. The solar panels are oriented almost vertically and should be generating power and charging the batteries, as the rest of the spacecraft warms up.
Also, Chandrayaan-3 was not designed to survive the lunar night; it does not have an energy source for nighttime heating like other long-duration missions.
"Chandrayaan-3 Mission:
Efforts have been made to establish communication with the Vikram lander and Pragyan rover to ascertain their wake-up condition.
As of now, no signals have been received from them.
