104. Well the plan was never to send humans today.

However these plans take decades to put into motion.
Planning today would be for humans in 2020.

Complicating things further is the fact that we only have 3 realistic windows to reach Mars this century.

Due to our dissimilar orbits Mars will only be "close" to earth 3 times this century. Launching at any other time would take much longer (30%-80%), require more fuel/mass, and more cost.

The first window is in 2020, the second in 2036, the third is 2060.
