The time of travel to #Mars can be reduced from nine months ⏳ to about four months. This would reduce #radiation ☒️ 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

Supersonic retropropulsion πŸ”₯: Beginning in πŸ“† 2014, #NASA and #SpaceX formed a three-year public-private partnership. The F9 boosters were outfitted with special instruments to collect data specifically on portions of the entry burn that fell within the range of Mach numbers and dynamic pressures expected on #Mars πŸ”΄. To everyone's surprise and delight, it worked πŸ‘ https://phys.org/news/2024-11-mars-approach-large-payloads-red.html
