So is Mangalyaan-2 going to have both a rover and a lander, or will it just have a lander and no rover? .... But what science instruments should it include?

For those who want more detail or are interested .. Things to study are recent Tianwen-1 and InSight landings (2021 and 2018 - see Sri Kumar's link) Both used a parachute to slow down during descent Both used a heat shield to protect the spacecraft during entry into the Martian atmosphere Both used ...

Doubtless, engineering and technology advancements have made things easier, but a Mars landing requires engineers to deal with an additional set of physics not existing on moon- aerodynamic forces and frictional heating. To be able to use aerodynamic forces to its benefit (i.e. slow down the lander...

Temperatures on Mars will still get quite cold, especially at night, where temperatures can drop to -128 C, nearly same as on the Moon. We saw how CY-3 lander+rover didn't even survive one lunar night, even though that period is equivalent to 14 days on Earth or Mars. Hardware on the surface of Mar...

My understanding is that Martian atmosphere makes EDL (entry-descent-landing) more complex than landing on the Moon. <snip> Thanks for all other info (which I snipped)-- But let me deal with one point only .. basically, point is: In soft-landing how much time (and capacity) to control and provide n...

Allow me to post this from basic physics and engineering principles -- Landing on the Moon is indeed more complex than landing on Mars -- because of its airless environment, which means : I think the presence of atmosphere, while it helps with braking/slowing down the lander, may create other compl...

If ISRO had it in their plan, then there is a possibility it gets launched this year. Interesting that they have a GSLV allocated for this as opposed to satellite launches. If they miss the 2024 chance, the next landing will be in 2027 ( ~1 year to get there). And all development gets delayed by 3 ...

Amber ji, a quick google tells me that the upcoming launch window for Mars is only from Oct-Dec 2024 - so any overrun on readiness date for the mission would likely force postponement until the next synod-based launch window which is Nov-Dec 2026. When ISRO already has major programs like Ganganyaa...
