In 1972, the Space Race officially ended as NASA sent one last crew of astronauts to the surface of the Moon (Apollo 17). This was the brass ring that both the US and the Soviets were reaching for, the “Moonshot” that would determine who had supremacy in space. In the current age of renewed space exploration, the next great leap will clearly involve sending astronauts to Mars.

This will present many challenges that will need to be addressed in advance, many of which have to do with simply getting the astronauts there in one piece! These challenges were the subject of a presentation made by two Indian researchers at the SciTech Forum 2020, an annual event hosted by the International Academy of Astronautics (IAA), RUDN University, and the American Astronomical Society (AAS).

Establishing a human settlement on Mars has been the fevered dream of space agencies for some time. Long before NASA announced its “Journey to Mars” – a plan that outlined the steps that need to be taken to mount a manned mission by the 2030s – the agency’s was planning how a crewed mission could lead to the establishing of stations on the planet’s surface. And it seems that in the coming decades, this could finally become a reality.

But when it comes to establishing a permanent colony – another point of interest when it comes to Mars missions – the coming decades might be a bit too soon. Such was the message during a recent colloquium hosted by NASA’s Future In-Space Operations (FISO) working group. Titled “Selecting a Landing Site for Humans on Mars”, this presentation set out the goals for NASA’s manned mission in the coming decades.
