What year do people travel to Mars?
No fixed year has been given for when the first manned space mission to Mars might take place- NASA has speculated in abstract terms that the first mission might be sent there some time in the 2030's, although this depends entirely upon how research and development progresses upon the vehicles needed to get to Mars, funding budgets, and what is or is not physically possible. Also, manned space travel is being increasingly sidelined nowadays as robotic probes become more advanced and sophisticated- it's felt in many scientific circles that we just don't NEED to go places ourselves when probes and satellites can do it for us. People probably will land on Mars one day, but it may not be until long after NASA has suggested it might.
