A dual left/right stereoscopic pair of ochre toned photographies capturing a Martian rock. This dual image is intended to be used to obtain a Stereo3D rendition of the scene through parallel viewing, and not cross-eyed viewing. The rock is darker than its surroundings, with a smooth texture, three bright speckles on its top face, and cavities on its sides.

According to the baseline scenario, a total of four cargo 📦 #Starships and two crewed 👩‍🚀👨‍🚀 Starships with a payload capacity of 100 MT each are available until 📆 2029 to bring the required systems to Mars. A power🔋supply system (#PSS) is needed for all activities on Mars. It could be investigated if a refueling ⛽ in #Mars orbit 🌌 scenario would enable return flights. https://www.nature.com/articles/s41598-024-54012-0.pdf

Parachute 🪂 is not the only means for descent, as high-mass class vehicles are emerging for human 👩‍🚀 missions. Shallow entry flight-path angles are preferred in order to achieve a lower terminal velocity to ensure a safe descent phase. Retro-propulsion could be activated at Mach 2 and above https://www.intechopen.com/chapters/72944#

#Starship would take between a mere 80 and 150 days to reach #Mars 🔴, depending on the launch window.

A shorter transfer time comes at the cost of higher fuel ⛽ requirements and less payload mass. Not only is it more difficult to reach the required delta-V, it’s also more difficult to stop. The spacecraft will need to brake harder to match velocities with Mars upon arrival https://www.marssociety.ca/2021/01/22/rocket-physics-how-to-go-to-mars

With a 6 m/s increase in the Delta-V budget, the deep reinforcement learning approach shortened the #aerobraking time by 68.3% 📉. The DRL algorithm does not encounter any thermal violations over 40 episodes compared to the 2.8 average thermal violations experienced by the state-of-the-art heuristic https://arc.aiaa.org/doi/10.2514/6.2022-2497

As the #spacecraft approaches Mars 🔴, it will need to perform a capture burn 🔥 to slow down and be captured by Mars' gravity. This requires a delta-v of about 0.7 to 1.3 km/s to enter Mars' orbit or to land on the planet's surface. #Starship 🚀 will enter #Mars’ atmosphere at 7.7 km/sec and decelerate #aerodynamically https://www.uc.edu/content/dam/refresh/cont-ed-62/olli/fall-23-class-handouts/SpaceX%208%20%20Mars%20%20Vision%20Summary.pdf

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

For a trip to #Mars 🔴, decreasing travel time by 10% necessitates twice as much fuel, while cutting travel time in half requires ten times as much. May prove worthwhile when considering factors such as decreased exposure time to #radiation ☢️ for crewed 👩‍🚀 missions. Extra speed must be lost at Mars. Many Mars missions do this, taking about 6 6️⃣ to 7 months for transit to the Red Planet. https://marspedia.org/Hohmann_transfer#Type-I_and_Type-II_Trajectories

@clive And a former nazi rocket scientist Werner von Braun created: ”Elon, the Techno King of Mars” in his 1952 science fiction novel: ”Project Mars”

The society of Mars was run like that very same technocracy, with engineers running it while a CEO-like absolute dictator calls the actual shots.

Coincidence? I think not. Musk lists his registered title as ”Techno King” in the official papers of Tesla inc.
