ISRO General News and Updates

What would be the power source?
Solar ?

As of now, probably yes...
though I had suggested a complete RTG + RHU setup haha

 

[SavageKing456]

Well, I'm thinking about using gyroscopic sensors to detect an impending dangerous position (above dangerous threshold), then automatically adjust wheel torque and orientation to counteract tipping, preventing the rover from overturning altogether.
It's real-time, so theoretically should be better than using mechanically deployed stabilizers.

I think you should keep mechanical stabilizers as well so that you can cope up with the failure

Will your budget even allow rtg+rhu?

 

[SammyBoi111]

Will your budget even allow rtg+rhu?

Nope, obviously. It was a wild suggestion, thought we could keep it representative in the abstract.
But if we do get selected, we'll have to build the model, so going the conventional route.

Some model level rtg is already tested

SPPU’s Physics department develops nuclear batteries for Isro

The project, which was initiated in 2015, was completed recently with Isro’s support which has an independent unit at the SPPU campus

Some updates

> ISRO to launch Chandrayaan-4 to bring back samples from Moon in 4 yrs: Somanath

> Agency chief says the first module of Bharatiya Antariksh Station, a space station which will be capable of conducting experiments with help of robots, will be launched by 2028.

> An experiment crucial for sustained human spaceflight will be “launched in the next three to four months,”.

> Somanath said that for sustained presence of Indians in space, ISRO is also working on developing an inflatable habitat module where the astronauts will be able to walk around and conduct experiments.

The SPADEX experiment will demonstrate autonomous docking capability. Docking is a process where two spacecrafts are aligned in a precise orbit and joined together

He said work was on to develop technologies such as robotic arm to collect samples, mechanisms for docking in the Moon orbit and Earth orbit, transfer of samples, re-entry into the atmosphere without burning up — this will also be demonstrated by the Gaganyaan mission that will send astronauts to low Earth orbit and bring them back to Earth.

ISRO is also working on technologies such as satellites that will be able to re-fuel other satellites in space and ISRO Servicer Module that will be able to use robotic arms for maintenance of the modules and even replace modules when needed.

While the first module in 2028 can be launched with the existing rockets, he said, for building the entire space station a heavier launch vehicle will be needed. Somanath said ISRO was working on designing the Next Generation Launch Vehicle (NGVL) that will have a capacity to carry 16 to 25 Tonnes to low Earth orbit.

More importantly, ISRO is in discussion with NASA and the European Space Agency to build a common interface between the Indian space station and that of these countries. This interface will make joint work possible, said Somanath, indicating the possibility of collaborating with these countries for the space station. The current International Space Station has been built in collaboration with several countries and is likely to be de-orbited in 2030. The common interface will also allow the Indian module to go and dock with the ISS, he said.

ISRO planning for LEO Constellation like Space X. China planning to deploy a mega-constellation of 13,000 low-orbit satellites to provide services to China, spy on rival networks, and even carry out sabotage missions. Few Details on Slide. @Karthi.

Highlights from loksabha questions

Q: the efforts that are being taken by the Government in reaching out to the academic community as well as young startups through hand-holding, ecosystem support and funding in the country’s backward areas;

A:efforts that are being taken in reaching out to the academic community as well as young startups through handholding, ecosystem support and funding in the country’s backward areas are as follow:
1. A national committee for adoption of space technology education in India is formed by IN-SPACe, with an aim to facilitate and promote the integration of space technology education across academic institutions in India, fostering awareness, skill development and research.
2. List of retired ISRO subject experts is published on IN-SPACe Digital Platform (IDP). NGEs can approach these mentors directly for expert advice etc.
3. Periodically invite willingness from the technocrats having experience in space sector as mentors and connect them to NGEs.
4. To encourage Students/Academic Institutions to carry out space activities, a committee has been constituted which will evaluate their proposal and provide necessary guidance.
5. In order to develop quality manpower in the space sector, INSPACe is periodically organising skill development short term courses in association with ISRO along with Seed Fund Scheme.

Finally explanation by dr. Nilesh m desai what happened to QUantess payload and it will be flown to next POEM hopefully

Here somnath ji is saying " it was scheduled to launch in last PSLV but couldn't launch due to readiness ishuee soon you will hear about it launch it as a demonstration in the orbit"

 

[Varoon2]

Will the PSLV XPoSAT mission carry any secondary payloads/ satellites. 455 kg ( weight of Xposat ) seems rather small for the PSLV

It will have POEM !!!!
