Does rover ramp has been taken back by lander, not seen in pics ?

Ramp is still deployed it seems.

Look at 3 legs at right side.
That big middle one is ramp.

The long thick black thing on the right is the ramp.

No, Mangalyaan-2 was planned way earlier than Venus mission.

No, just a proposal which is probably is yet to undergo study.

It comes every 19 months actually. ISRO wants an advanced robotic mission for Shukryaan with aerobots (drones and lander probably) instead of just orbiter hence a long term proposal was adopted and 3 timelines arr estimated to be skipped per missions in between.

Gaganyaan and sustained human spaceflight (repeated Gaganyaan or space station) is priority over any planetary mission and has pushed timeline of everything ahead.

Mangalyaan-3 and not Mangalyaan-2 was supposed to have lander per what Somanath said last time. ISRO wanted to send a massive multi tonne orbiter like MAVEN to Mars.

Even if proposals might have changed, don't expect any Mars lander anytime soon. Mars lander will have to be built entirely different to face friction and heat of Martian atmosphere (which Chandrayaan did not have to worry about). And then, there are Gaganyaan & Chandrayaan-4 and many other priority missions in line.

And yes, landing a rover on Mars is a pinnacle of robotic spacecraft technology. So is sending humans in space.

Sending only heavy lander to mars will handle by LMV3

No, Mars lander will likely be handled by NGLV. LVM3 won't handle any light or heavy Mars lander.

Given Mars has atmosphere, has huge weight, most part of weight will be absorbed in heat shields and putting large thrusters leaving little space for any meaningful scientific payload for a 5 tonnes class probe.

So no, LVM3 is unlikely to handle Mars landing (or lander payload will be incredibly small even if they manage somehow). Still, very unlikely.

Govt needs to increase ISRO budget. A Saturn V class rocket is needed for a serious and meaningful future space endeavour.

There have been serval SHLV class concepts studied and abandoned since there was no requirement.

That requires a mission. Without a Gemini class 50 tonnes spacecraft on cards, India doesn't have any use of a Saturn V class rocket. Before building a 50 tonne spacecraft, India needs to master landings, interplanetary mission, human spaceflight and rendezvous docking. So, ISRO's need of the hour is a Delta IV Heavy class rocket (which is already under development) and not Saturn V class rocket. That would be thought of after India has maintained a space station for 5 years.

India doesn't need a Saturn V class rocket until 2040.

Than we can hire spaceX service to launch heavy lander.

We don't have lander either to land. It will take several years to develop and there are other priorities. So no. A heavy lifter will be developed on time accordingly with development of spacecraft.

Technically LVM-3SC can handle Mars lander....entire stack of spirit rover weighed 1100kgs & was directly injected into Mars Transfer Trajectory by delta-2 rocket(similar to GSLV-MK2), entire Viking-2 stack (orbiter, entry capsule,lander) weighed 3700kg & was launched by Titan-3E(similar to LVM-3SC ) .so LVM-3SC on paper atleast can handle Mars Lander+Rover+Entry Capsule+ Data relay Orbiter, if they weigh less than 4000kg....which imo is very much possible & in the absence of SCE-200, we can use Russian RD-191 which was earlier indicated by ISRO chief in his presentation recently....

Spirit rover weighed just 185 kg & did breakthrough science on Mars, we don't need a Curiosity sized huge rover on Mars...but yes if we want launch on LVM-3SC the orbiter cannot have meaningful science payloads, other than a High Res Camera just like CY-2's OHRC

I was talking about LVM3 and not LVM3-SC.

The case for a small lander will still remain since a Mars lander will be much more complex than a moon lander.

NGLV is atleast 5 years away
Till then we won't see MLM(Mars landing mission)?

Indeed, this is what landing of Perseverance rover mission 2 years back was.

Yes, MLM isn't on cards either IMO. With Chandrayaan-4 development and Gaganyaan launches, ISRO is already packed till last of this decade.

The case for a small lander will still remain since a Mars lander will be much more complex than a moon lander.

Naah, Mars Lander will be relatively easier than moon lander, in moon landing entire velocity have to be killed by lander's thrusters alone, but for Mars landing most of the velocity is killed by entry capsule during atmospheric entry & by parachute thereafter, so lander thrusters are engaged only at terminal phase, so less complex than moon landing, if LVM3 cannot carry a rover we can do lander alone + data relayorbiter mission like phoenix lander whose stack weighed just over 700 kgs which was directly injected into MTT by delta-2 rocket , so this option is also possible.....

a phoenix like lander + entry capsule+ data relay orbiter will weigh around 2.2 tons which can easily be done by LVM-3

as far as time line is concerned, CY-2 was developed in 5 years & CY-3 was developed in 4 years,so Mars Lander to can be developed in 4 years for 2027 launch window

Is Chandrayaan-4 and LUPEX same? Typing Chandrayaan-4 on Google returns LUPEX in result.
