It makes sense to use the Martian #atmosphere to help with deceleration and save on propellant. https://www.youtube.com/watch?v=5seefpjMQJI This method has been tested and validated on Earth, using #SpaceX #Falcon9 first stages in the high atmosphere to simulate #Martian conditions https://marspedia.org/Landing_on_Mars#Powered_landing

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

To get enough fuel β›½ into #orbit for a #Mars πŸ”΄ mission would require at least 10 launches of the #SLS rocket, or about $20 billion πŸ’°. Just for the fuel. To use traditional propulsion, one needs to push the boundaries of #reuse ♻️ and heavy lift rockets to extreme limitsβ€”which is precisely what #SpaceX is trying to do with its fully reusable launch system https://arstechnica.com/science/2021/02/report-nasas-only-realistic-path-for-humans-on-mars-is-nuclear-propulsion

The #SLS and #Orion spacecraft projects are of such a scale that they spend money in all 50 states and Puerto Rico, creating #parochial interest in nearly every congressional district.

Prof Logsdon* expects big changes under #Trump, Mr #Musk and Mr #Isaacman: scrapping programmes, closing NASA centres and more contracting out to #SpaceX, #BlueOrigin and other private sector firms. "There is a delicate balance between the interests of #NASA, #Congress and the #WhiteHouse."

Mr Isaacman has called the #SLS "outrageously expensive" and said that the major aerospace contractors are "incentivised to be economically #inefficient". https://www.bbc.com/news/articles/cn93797z2dpo
