We may reach Mars by 2060s: NASA scientist on Trump's 2033 target

NASA scientist Robert Howard has said it would be impossible to make the 2033 deadline for Mars, set by NASA under US President Donald Trump's administration. "I think in our current approach, we're going to be lucky to do it by 2037," Howard said, adding if he were to be pessimistic, and assume political constraints "it could be the 2060s".
