Former Apollo astronaut Buzz Aldrin said NASA should keeps in vision bigger goals like putting people on the moon.  He made these comments on the 40th anniversary of his landing on the moon. He supported NASA’s decision to stop sending men to the moon that NASA took in 1972. Aldrin says Mars is “much more suitable to earthlings, much more habitable. It’s possibly the source of life.”On his first steps on the moon, he said that place was “so desolate, so totally lifeless. It probably hadn’t changed much in 100,000 years.”
