    Elon Musk s'est souvent hasardé à faire des prédictions, qui se sont révélées régulièrement fausses. Malgré tout, le milliardaire américain a fait une autre promesse : selon lui, la fusée Starship sera sur Mars dans cinq ans.

    It has now been several weeks since NASA's tenacious helicopter on Mars, Ingenuity , made its final flight above the red planet.

    This happened last month. On January 6, Ingenuity flew 40 feet (12 meters) skyward but then made an unplanned early landing after just 35 seconds. Twelve days later operators intended to troubleshoot the vehicle with a quick up-and-down test. Data from the vehicle indicated that it ascended to 40 feet again during this test, but then communications were ominously lost at the end of the flight.

    On January 20 NASA reestablished communications with the helicopter, but the space agency declared an end to its flying days after an image of the vehicle's shadow showed that at least one of its blades had sustained minor damage. This capped an end to a remarkable mission during which Ingenuity exceeded all expectations .

      Mars experienced a precursor to plate tectonics

    Early in Earth's history, the heat left over from the collision that formed the Moon left its surface an ocean of magma. As it cooled, its crust was frequently shattered by massive impacts that dwarfed the one that did in the dinosaurs. Somewhere in between that and the onset of plate tectonics, it's thought that a distinct process caused parts of the crust to sink, while volcanism brought material to the surface that would later form the continental crust.

    While we can model this period, we can't really search for evidence to back our models, since any of this early crust has been eroded or transformed by the plate tectonics that eventually ensued. However, a team of researchers is suggesting that there might be a way to see what this process looked like, and it doesn't involve a time machine. Instead, it involves studying the surface of Mars.

    Lots of volcanoes

    On Mars, plate tectonics never got going. So, while some areas of the planet have been transformed in a way that keeps us from studying the earliest periods of Mars' history—looking at you, Olympus Mons —scientific consensus is that nearly half of the planet's surface is over 3.6 billion years old. This provides the opportunity to study processes that occurred in the first half-billion or so years after Mars formed.

      Before Ingenuity ever landed on Mars, scientists almost managed to kill it

    MiMi Aung could barely contain her excitement as she drove up Oak Grove Drive, the leafy thoroughfare leading to NASA's Jet Propulsion Laboratory.

    Aung had spent her formative years in Burma and Malaysia, two countries without a space program. A career in aerospace seemed beyond her reach. Yet here she was, at 22 years old, with a job interview to possibly work on the Deep Space Network. Aung dreamed of helping NASA intercept and amplify faint signals sent back to Earth from humanity's farthest-flung spacecraft, including the Voyagers.

    "I remember it like it was yesterday," Aung said.
