RE: https://mastodon.social/@europeanspaceflight/116475858483213797
The clearest price comparison for a #VegaC 🇪🇺 launch is India’s 🇮🇳 #PSLV rocket, which has a comparable payload capacity to #LEO. The figure is less than half 📊 the stated sticker price of a Vega C flight.
-
• #KID separated from #PSLV ~18 minutes after takeoff, likely as a result of the flight anomaly
• The demo craft was able to withstand peak forces around 28 Gs
• KID’s thermal protection system was able to maintain a temperature of ~30 degrees Celsius, while external temperature readings showed ~85 degrees 🌡️ Celsius
• The vehicle successfully transmitted data, while screaming through the atmosphere at a non-nominal trajectory -
The second #PSLV launch in a row has ended in failure, at almost the same time during the burn of the 3rd stage as the last one: https://x.com/Dillonshrop06/status/2010579794191401168 - so far ISRO hasn't explained anything.

India’s PSLV launch fails during ascent, 16 satellites lost
-
"
India's space agency Isro has successfully launched the PSLV-C62 mission to deploy 16 satellites into a sun-synchronous polar orbit and marking a stellar start to the 2026 launch calendar. However, the deployment could not be confirmed.

In four hours the webcast https://www.youtube.com/watch?v=GgYh2Vv87ik of the launch of #PSLV-C62 - a return to flight for this rocket after a launch failure a while ago - carrying EOS-N1 and 15 co-passenger satellites into Sun Synchronous Orbit from the Satish Dhawan Space Centre in India should begin: see https://www.isro.gov.in/media_isro/pdf/PSLVC62/PSLV_C62_Brochure090125.pdf and https://www.isro.gov.in/Mission_PSLV_C62.html for details.

🚀 Le lancement du satellite radar d'observation de la Terre EOS-09 par l'Inde a échoué en raison d'une performance insuffisante du troisième étage de la fusée #PSLV, empêchant ainsi son placement en orbite.
1er échec de la PSVL depuis 2017 et après 21 vols réussis -

Europe says farewell to eclipse-making Proba-3
"
"The mission’s two spacecraft – which will manoeuvre precisely in Earth orbit so that one casts a shadow onto the other – have departed the facilities of Redwire Space in Kruibeke, Belgium. The pair will be flown to the Satish Dhawan Space Centre, near Chennai, for the launch campaign to begin."31.10.2024

Spent stage of Indian rocket that washed up at Australia has found a nice home at Scitech Planetarium in West Perth.
https://www.scitech.org.au/2024/07/space-rocket-debris-lands-at-scitech/
It has a name as well!
'Li-Ligh' which is acronym for 'Left India, Landed in Green Head' 😀

(Contd.)
With key test done, Proba-3 will be shipped to SDSC-SHAR in India on 21 October for a planned launch by PSLV-XL launcher on 29 November 2024.

ISRO conducts 665 second long-duration hot test🔥 of Additively Manufactured #PSLV fourth stage (PS4) Liquid Engine.
https://www.isro.gov.in/ISRO_successfully_conducts_long-duration_hot_tests.html
PS4 engine design optimized for #AdditiveManufacturing by the Laser Powder Bed Fusion technique brought down the number of parts from 14 to 1, and eliminated 19 weld joints. Raw material usage reduced (13.7 kg of metal powder) compared to the 565 kg of forgings and sheets for conventional manufacturing process) and production time reduced to 60%.

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"
