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
