ISRO's Mars Orbiter Mission

It’s not so simple. When it is closest to Earth, Mars is about 54 million km away and about 400 million km away when it’s on the other side of the sun. Isro’s Mars Orbiter Mission took 322 days to enter the Red Planet’s orbit. Human forays into Mars could be a reality as early as 2030 and human settlement thereafter. We look at some of the serious challenges astronauts could face and how scientists are trying to overcome them.
