ISRO has a good opportunity to send an orbiter mission to one of the ice giants. No one has done such a thing till now and very little is known about the planets. ISRO and Indian universities will have a huge advantage to study these planets and publish papers before the western universities...

The lander has heaters (resistive) as well as radiators (to reject heat from electronic components).

This type of question is asked by people like Mamata Banerjee, not someone in DFI.

We have 14 days to do some incredible science on the south pole. After that we'll shift to Aditya.

It's the exact opposite. Due to weak gravity and no atmosphere, lunar dust takes minutes to settle. Also, lunar dust is electrically charged, so there might be other effects.

Atleast 3 hrs later after system health checks have been performed. Wait for sometime, let the lunar dust settle.

Congratulations to ISRO!!!!

At this moment, I don't have any information on the control system used for landing in CY-3. But here's a Chinese paper studying the control system used in one of their landers: https://www.degruyter.com/document/doi/10.1515/astro-2022-0217/html They're using sliding mode control. I'm sure...

Is ISRO using some variant of sliding mode control system (for the fine braking phase)?

That's for stars which are atleast 10 times solar mass. I was talking about sun like stars.

For a sun like star, when hydrogen fuel becomes depleted, fusion stops in the core. So, we no longer have the nuclear explosions which keeps the star from collapsing due to gravity. So, it starts to contract. Due to contraction, pressure and temperature both increases. At some point temperature...

It's an M class solar flare, there have been more powerful flares in the past. Also, the first symptom in a dying star would be that it starts shrinking.

The spacecraft has sufficient protection for electromagnetic radiation, so don't worry.

Why do you think so? Do you have any sources?

This answer is a joke lol. GPT 4 doesn't have a clue about these things.

The reasons to not use a high ΔV burn are: This is is an unmanned mission. We don't need to send the lander in a few days, when the same can be done with lesser ΔV (using Oberth effect) but requiring more time. Second reason is that we don't have an engine with required thrust to apply the...

UK has become a colony of USA. They can only bark, but nobody cares. Just wait and see what happens to them as Asia and India become the financial capitals of the world.

How can you say that chance of crash is 99% when we had nominal trajectory after hard breaking? There is equal probability of a crash and comms failure.

If we analyze the projected trajectory to the actual, we see that the horizontal component of velocity was reduced more than projected. That means the lander will land in a different place with different elevation(probably?). If the the elevation is higher then the lander can strike hard and the...
