# What is the difference between a Trans-Mars Injection and a Mars Transfer Orbit?

So I'm using this transfer orbit calculator and when simulating a transfer from LEO to Mars, in the delta-v breakdown, appear two different values: TMI (Trans-Mars Injection), at around 3000 m/s, and MTO (Mars Transfer Orbit), at around 600 m/s.

What is the difference between these two?

However, the numbers you give agree with this answer analysing the same trajectory. This leads me to conclude that the "TMI $$\Delta v$$" is for the transfer injection burn (leaving LEO into an elliptical trajectory intersecting Mars' orbit) while the "MTO $$\Delta v$$" is the burn after arriving at Mars in order to enter Mars orbit.
