Mars Launch Windows (2020-2030)

Launch windows calculated from trajbrowser.arc.nasa.gov

Maximum total ΔV = 7 KM/S | Maximum mission duration (Earth to Mars) : 240 days

We have 5 spaceflight launch windows to go from Earth to Mars between 2020-2030:

  1. Q3 2020:
    Unfortunately, Starship will not be ready for this window.

  2. Q3 2022:
    The focus may be for the #dearMoon mission in 2022, still, we can see the first few cargo/logistics missions in this window if SpaceX could work it both in parallel.

  3. Q4 2024:
    This is the 1st primary window to send cargo/logistics to Mars

  4. Q4 2026:
    The 2nd primary window to send cargo/logistics, and I think SpaceX would need 2 cargo/logistics windows (multiple Starship launches for each) before sending humans to Mars, but maybe SpaceX will be ready in this window to send humans.

  5. Q4 2028/Q1 2029:
    This is the primary window that I think most likely for SpaceX to send humans to Mars.

What do you think could be realistically done for each of the 5 launch windows?

Edited to correct the table sorting.
