Indian Venus Missions

On topic, Venus is hardest rocket planet in reach where some country has reached.
There are harder things to do around satellites of Jupiter and Uranus where no one has gone or even deeper space around Neptune and Pluto.

We anyway are not talking about. Maintaining a space station is technologicall & financially harder and stronger way of space powet projection. Landing humans on Moon will be greater.


But yes, you are right. If we soft land on Venus, Mars will be cakewalk.

Mars does have an atmosphere. There is a reason landers have heat shield.

Given Mars has lower gravity and not atmosphere harsh as Venus, experience of landing on Venus may actually make Mars landing way easy.

Relatively speaking and comparing it to Earth. Mars has like 1% of the Earth's atmosphere and for the purpose of aero-braking, practically nonexistent. . My point is that Earth has a sufficient atmosphere to slow down orbiting vehicles to the point where it does not need fuel to land. Whereas, in Mars, you do need fuel to slow down and land after exceeding a certain size which was the Perseverance mission.

Not really. Mars has no atmosphere and still have enough mass to generate gravity to smash things if they cannot brake properly.

Right now NASA has a hard time of how to land bigger vehicles as they are approaching their upper limit of size given their technological advances.

Venus has the opposite problem of Mars. Its dense atmosphere slows down the descent speed, which exposes the probe to crushing temperature and pressure for a very long duration during the descent phase.So by the time it reaches the surface, the probe would have already ruptured.

Besides unlike Mars where landing is the most challenging part due to it's thin atmosphere, on Venus post-landing operations are equally difficult as the lander is exposed to a near 500 °C temperature and 92 atms of pressure. All scientific probing and imaging operations have to be done quickly as the immense pressures and temperatures would eventually degrade the materials and electronics of the probe.
