Interview: Valentina Salcedo
Can traveling to Mars soon become a reality? According to NASA, we will reach the red planet by 2038. However, the mission will be very long because at least 3 months are needed to reach Mars.
We interviewed doctor and professor at the University of Pittsburgh, Clifton Callaway, who was lecturing at the University of Trieste this summer, and who is studying, on behalf of NASA, how to prepare the human body for the weightlessness of missions that will last at least two years.
