A fusion-powered #spacecraft could make the trip to #Mars 🔴 in 90 days or less.The roadmap identifies milestones in #FusionPropulsion technology to deploy fusion spacecraft in the 2030s, on par with the vast majority of fusion developers’ commercialization timelines (89% of fusion companies* anticipate fusion on the grid in the 2030s or before) https://www.fusionindustryassociation.org/fia-launches-fusion-spacecraft-propulsion-roadmap

Even on a planet filled with strange geology, this one stands out. Skull Hill may be a volcanic loner, a battered survivor of Mars’ wetter days, or something stranger. Whatever it is, it’s another reminder that the Red Planet isn’t done surprising us.

"#Musk's timeline will prove a bit optimistic, but even accounting for that, we are on the threshold of a new era.” Despite setbacks, #SpaceX continues pushing boundaries with its rapid iteration approach. The question remains not whether humans will reach #Mars, but when. https://www.forbes.com/sites/luisromero/2025/03/07/spacex-explosion-blasts-mars-timeline-2026-goal-likely-delayed

Supersonic retropropulsion 🔥: Beginning in 📆 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 🔴. To everyone's surprise and delight, it worked 👍 https://phys.org/news/2024-11-mars-approach-large-payloads-red.html

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

#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

From Earth to #Mars lasts about 200 days. To safely go from those speeds down to zero in that short amount of time requires “slamming on the brakes”. Successful #aerobraking depends upon precise navigation, knowledge of weather, and a solid understanding of the forces the craft can withstand. https://science.nasa.gov/planetary-science/programs/mars-exploration/mission-timeline

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#

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 #aerodynamicallyhttps://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

Content Warning

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
