  • The future path of the rover shows a number of waypoints that are located outside the crater. Once those waypoints have been investigated the team will decide where the rover will explore next. There are many interesting areas inside and outside the crater that will be considered for future exploration. If they decide to re-enter the crater using the same path they used to leave the crater, then the rover would pass close to the helicopter. Maybe they will attempt to make contact and see if it was still gathering the environmental data it was tasked with after it was damaged in it last landing two years ago (January 18, 2024), or maybe just image it from afar to record its condition. Time will tell…




  • You want her number?

    Agreed 3000 km is only a short distance, especially when you consider the Mars / Earth distance is currently over 360.12 million km

    I recall asking my teacher the same question regarding trigonometry for when I’d need it in real life :) And here I am today LOL

    If I have issues with my Pythagorean theorem formulas in Libreoffice Calc (a2 + b2 = c2), I’ll certainly ask you for her number :)

    ‘Calc’ does a pretty good job of calculating their positions based on their positions reported by JPL after each drive. But I really should update my formulas to include the nominal curvature of the surface of the planet, as that would certainly increase their distance apart :)




  • Why are the moon as mirror and better transmission protection algorithms no sufficient ways?

    I don’t believe the moon is far away from Earth to act as a reliable relay for Mars - Earth communications.

    A number of relay satellites could be parked at different Lagrange points (see attached image), but the cost of such a system would probably not be approved for robotic mission, as all space fairing nations have limited budgets, and robotic missions can just be paused for a few weeks during conjunction.

    If extended crewed missions to Mars become a reality, I would think it would be essential to have such a communication system in place if the missions were planned to occur during a Mars-Earth solar conjunction.
