Do you think India could send humans to Mars? Which country will send its first manned mission to Mars?
Bhaskar Dutta, I am an Indian by birth and by heart
Sending man to Mars has its own complications that needs to be addressed. These include:
The largest limiting factor for sending humans to Mars is funding. The estimated cost of sending humans to Mars is roughly 500 billion U.S. dollars, though the actual costs are likely to be more. In the late 1950s, rivalry between the Soviet Union and the United States stimulated a national priority to send humans to the Moon. Under the current global geopolitical climate, however, government funding of these programs has decreased.
Recent participation of private companies in space travel and participation by new nations such as India may present new opportunities.
India’s space agency ISRO (Indian Space Research Organisation) spent a mere $75 million to launch a small spacecraft bound for Mars, 140 million miles away. The Indian prime minister had previously joked the mission’s budget was lower than Gravity, the Sandra Bullock and George Clooney sci-fi film which was £13 million more expensive.
The general philosophy of India's ISRO is cost effectiveness. The Russians look for robustness and the Americans go after optimisation. The aim at ISRO was how to get to Mars on a budget. Hence, cost may not be a barrier for India to venture into a manned mission to Mars.
A spacecraft would require enough thrust to push itself back and travel a large distance from Mars to Earth. This would require a lot of fuel and would be difficult to carry them in the same space craft. So, India will have to make multiple visits to Mars and store enough fuel there before planning for a manned mission.
India successfully placed an un-crewed Mars Orbiter Mission (also called Mangalyaan) satellite in Mars orbit in 2014. ISRO plans a larger follow-up mission called Mangalyaan 2 by 2020. This mission will likely consist of a lander and a Mars rover. Hence sending multiple spacecrafts to Mars would not be an issue for India.
Indian work culture has a schedule, that’s driven to the extreme. This, apart from preventing cost over-runs, it also minimizes the time spent for mission. The Mangalayan mission had taken just 15 months months from announcement to the liftoff.
Elsewhere in the world, even space scientists have a 35-hour workweek. For Indian scientists, 12-18 hour-days are common. During the launch period of Mangalayan, many of ISRO scientists were working 20 hour-days. Being time effective makes Indians more prone to being successful and timely completion of required development.
There are claims that a long-term investment in space travel is necessary for humanity's survival. The benefits of establishing a human presence on Mars would increase public/private interest to join the cause and spark a cooperation.
In 2018, ISRO released an Announcement of Opportunity seeking proposals from the Indian science community for conducting experiments that could be carried out during the first two robotic flights of Gaganyaan. The scope of the experiments is not restricted, and other relevant ideas will be entertained.
In December 2018, the government approved funds for a 7-days crewed flight of 3 vyomanauts (a term used for Indian astronauts/cosmonauts, where, vyoma means 'space' or 'sky' in Sanskrit) to take place in December, 2021. If completed on schedule, India will become world's fourth nation to conduct independent human spaceflight after the Soviet Union/Russia, United States and People's Republic of China. After conducting crewed spaceflights, India also intends to continue with efforts with a space station program and possibly a manned lunar landing. The success of manned mission to Moon would increase the possibility of manned mission to Mars.
However, no plans for an Indian human mission to Mars have been made public by Indian government.

Rahul Buddala, Men are from MARS
Not just India, any country in this world with a developed space program cannot send man to Mars at this point of time.
The Martian movie can be great to watch, but with current technology it takes 2.5 yrs to send a man to Mars with optimum usage of fuel, and nearly 8-9 months with a decent fuel burn. Austronanuts cannot stay in space for such long durations. It would effect their body physically.
And on top of it, it's a boring 2.5 yrs. Just black space all around. The people on board will be bored to death.

Will India send a person to the Mars? Yes
When will India send a person to the Mars? Within next 15 years
Will India be the first one to send a human to mars? No. Elon Musk will do it within next 10 years. Maybe he’ll select a few Indians to go to the Mars!
Has India sent a person to Mars? Maybe..at least, according to our mythology, we’ve sent people not not just mars, but other galaxies and Universes too!
