The goal of sending astronauts to the surface of Mars has been a major point of contention, with the likes of SpaceX CEO Elon Musk arguing that we should skip the Moon entirely in favor of the Red Planet — despite NASA already being deeply invested in returning astronauts to the lunar surface for the first time in over half a century.
It’s an enormously more complex journey that will require major leaps in technology, from keeping astronauts safe from the harshness of outer space for months at a time to ensuring they have shelter and enough air to breathe once there.
Unperturbed, a consortium of American scientists and engineers filed a report on Tuesday that stridently makes the case for putting boots down on the surface of Mars. Why? To finally figure out whether we’re alone in the universe, they say.
“We’re searching for life on Mars,” MIT aeronautics professor Dava Newman, who cochaired the committee that drafted the report, told Ars Technica. “The answer to the question ‘are we alone’ is always going to be ‘maybe,’ unless it becomes ‘yes.'”
While NASA has successfully sent five remotely-controlled rovers to the planet’s surface, sending a crew there remains a distant prospect.
But at least there’s a sense of growing momentum. SpaceX space tourist and billionaire jet fighter pilot Jared Isaacman, who has previously argued we can simultaneously send humans to both the Moon and Mars, is widely expected to be confirmed by the US Senate sometime next week as NASA administrator.
The 200-page document pulled together by Newman and her collaborators, which was in development long before Trump took office in January, was designed to identify the top priority science objectives during future crewed missions to Mars. Among the top eleven objectives are the search for life, the Red Planet’s geology, how well humans can survive on its surface, and where future space travelers could find resources.
They concluded that sending a crew to Mars for 30 Earth days — and delivering the necessary cargo during a subsequent mission to allow future astronauts to stay there for up to 300 Earth days at a time — made the most sense for an inaugural campaign.
Yet plenty of major challenges remain. For one, astronauts face the threat of being exposed to copious amounts of deep-space radiation. Then there’s the potential of biologically contaminating the surface, which could threaten life there if it indeed exists.
“NASA should continue to collaborate on the evolution of planetary protection guidelines, with the goal of enabling human explorers to perform research in regions that could possibly support, or even harbor, life,” the report reads.
