ISRO General News and Updates

[Vamsi]

Slightly off topic,but the thing we all like to hear everytime ISRO launches a rocket

Debris seems to tbe PSLC third stage which often gets dumped near Australia shores:

ISRO, BARC join hands to develop nuclear engines for rockets

ISRO and BARC are developing nuclear-powered engine, RTGs, to power satellites on deep space missions. RTGs use radioactive materials to generate heat, which is then converted to electricity to charge batteries and provide motive force. 5W RTG is the target. US spacecrafts have used RTGs in the...

But somewhere i read that RTG already developed and is in testing phase. Dont know this report is old or new one.

Not rocket thrusters but spacecraft batteries.

@Vamsi, Any idea how long it takes to setup such a test each time? And what is the cost of fuel in such tests? Is it a back breaker or small enough to do such tests ample number of times?

After Chandrayaan-3, These Are ISRO's Next 6 Missions And Their Respective Costs

GSLV will be retiring after few more launches- ISRO chief Dr. Somanath

 

[SKC]

Listing here from above posted article:

1.ADITYA-L1-2023
Major objectives

• Understanding the Coronal Heating and Solar Wind Acceleration.
• Understanding the initiation of Coronal Mass ejections (CME), flares, and near-earth space weather.
• To understand the coupling and dynamics of the solar atmosphere.
• To understand solar wind distribution and temperature anisotropy.

Uniqueness of the mission

• First spatially resolved solar disk in the near UV band.
• CME dynamics close to the solar disk (~ from 1.05 solar radius) and thereby providing information in the acceleration regime of CME that is not observed consistently.
• On-board intelligence to detect CMEs and solar flares for optimised observations and data volume.
• Directional and energy anisotropy.


2. NASA-ISRO SAR (NISAR) Satellite-January 2024
The NISAR Observatory will be launched from Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota, on the southeast coast of the Indian peninsula, on the GSLV expendable launch vehicle contributed by ISRO. The target launch readiness date is January 2024. And the NISAR observatory will be launched from Indian Soil in the first quarter of 2024.


3. SPADEX-Third quarter of 2024
Objectives
-Autonomous rendezvous and docking
-Controlling one spacecraft with the attitude control system of another spacecraft while in docked configuration.
-Formation flying
-Remote robotic arm operations


4.Mangalyaan-2-2024
It had been mentioned that Mangalyaan-2 would be launched after moon mission Chandrayaan-3. The mission will reportedly include a hyperspectral camera, a high-resolution panchromatic camera, and a radar to understand early Martian crust, recent basalts, and boulder falls.


5.Gaganyaan-2024
Gaganyaan, India's first human space mission, is set to launch in 2024. The unmanned ‘G1 mission’ will launch in the fourth quarter of 2023, the second unmanned ‘G2 mission’ will launch in the second quarter of 2024, and the final human space flight 'H1 mission’ will launch in the fourth quarter of 2024.


6. Shukrayaan 1–2031
Optimal launch windows from Earth to Venus occur once every 19 months. This is why ISRO has ‘backup’ launch dates in 2026 and 2028 should it miss the 2024 opportunity. But even more optimal windows, which further reduce the amount of fuel required at liftoff, come around every eight years.

Neither Mangalyaan-2 nor Shukrayaan are approved projects yet

The aim of article is to mention the projects which would be coming in future from ISRO.

GSLV will be retiring after few more launches- ISRO chief Dr. Somanath

only known remaining GSLV launches are INSAT-3DS(Oct-2023),NISAR,(Jan-2024),NVS-02 to 05,IDRSS-01 & 02, GISAT-2 & RLV-ORV(mid 2026), all of them will be completed by 2026, so we expect its retirement in 2026

Please provide news source of statement stating GSLV will be retired. And wil NGLV be ready by that time or is it merely called LVM3 or something like that?

Even the GSLV MK3 won't be used for very long. Once the Methlox engine as well as the NGLV gets made(probably by early 30s), we would be jumping to NGLV. Infact even SCE200 is projected to not see much action. This was hinted by the Dr Somnath himself!!

Then would it make sense to keep the GSLV Mk3 around until the NGLV is ready and proven?

MK3 will work for another decade for sure!! Especially when are yet to utilize of SCE200!!
