The time of travel to #Mars can be reduced from nine months β³ to about four months. This would reduce #radiation β’οΈ doses by over 60% compared to the Hohmann transfer. This trajectory uses 4.62 km/s of deltaV. #SpaceX#Starship is designed for about 6 km/s of deltaV. The return velocity of #Apollo was about 11 km/s https://marspedia.org/Aerobraking
