Only for financial reasons, otherwise we would have been far ahead of India.

So the high IQ isn't helping much to solve your financial problems?

We all know that India has the lowest IQ. Pakistan has more IQ than India.

Yeah, also Pakistan is the 2nd fastest growing economy, have a successfull space program, not a failed state, no killing of people in name of religion, won all wars against India, conquered Kashmir and I have a hot girlfriend.

Ohh come on,the descendants of Mard-e-Momins may have got high level of physical strength but when it comes to I.Q. you guys are even lower than that of Somalia or Chad and everyone on this planet knows this.This is the sole reason why you haven't been able to build a simple 2 stroke moped engine let alone a satellite on your own and depend on your sugardaddy China for literally everything!!

“The equipment on board the lander and the rover will have a mission life of just 14-15 days. The extreme temperatures on the moon will eventually destroy them,”

Can somebody clarify this 15 day mission life ??

Here is something from our past and something for the future.

not bad for low IQ society, isn't it.


@Mike_Brando @ni8mare @me_itsme : Mates don't indulge in mudslinging. Nobody can be-little our efforts by making fun of it and you guys know it well.

Is it me or the rover looks flimsy?

Exactly my thought. It doesn't look strong enough to bear the harsh environment / terrain of the moon. But I am sure our engineer and scientists must have thought about it in detail.

Sir are you referring to the wheel links?
I'm not sure but it looks like these have been designed to move in relative elevation to each other (ie uneven ground). We can see a link connected by two pins (one at body end, second with wheel center). Secondly there is no axle arrangement, which means each wheel can be at different elevation wrt to others.
Also there could be a ball and cup joint between wheel and link (some sort of spherical bearing) so that wheel can sway.
One thing i could not understand is how the vehicle is going to make a turn?
---------------------------

wrt to material
I was tempted to think that wheels are made of titanium, but Titanium doesn't have that bright a lustre, could that be some sort of Aluminum alloy?

To turn left, the rover could jam the left side wheels and use the torque from right side wheels and pivot in circle. Same could be done to turn right. I am also not sure about the ground clearance. It looks too close to the ground.

Alternately, there could be a double cylinder piston arrangement (for each half axles, connected to three wheel on right and left side as shown in sketch below. This is a typical arrangement for each side.
