NASA's Perseverance records first-ever sounds of rover driving on Mars

Sound waves behave quite differently on Mars than on Earth.

  • NASA's Perseverance rover landed on Mars on February 18, and is currently preparing to begin its main mission of searching for signs of ancient life.
  • The rover contains two microphone systems, one of which was recently used to capture sounds of the rover traveling at speeds below .01 mph.
  • NASA hopes to return Perseverance's rock collection to Earth by 2031.

  • The bacteria were collected as part of a surveillance program that tasks astronauts with regularly collecting samples from eight sites aboard the International Space Station.
  • The bacteria discovered on the space station belong to a family of bacteria that helps plants grow and blocks pathogens.
  • Finding sustainable ways to grow food is critical to any long-term space mission.

NASA's Perseverance rover has a 1997 computer chip brain. Here's why.

It may be old tech, but it's super-reliable.

  • A special super-tough version of an old chip made famous by Apple is running the show on NASA's Perseverance Mars rover.
  • The chip is slow by modern standards, but meets the reliability test.
  • The chip can be bombarded with radiation and still keeps on going.

    Best. Science. Fiction. Show. Ever.

    "The Expanse" is the best vision I've ever seen of a space-faring future that may be just a few generations away.

    • Want three reasons why that headline is justified? Characters and acting, universe building, and science.
    • For those who don't know, "The Expanse" is a series that's run on SyFy and Amazon Prime set about 200 years in the future in a mostly settled solar system with three waring factions: Earth, Mars, and Belters.
    • No other show I know of manages to use real science so adeptly in the service of its story and its grand universe building.

    Scientists grow extremophile microbes on rocks from Mars

    The results could help NASA's Perseverance rover find evidence of ancient life on Mars.

    • In a recent study, researchers simulated the environment of ancient Mars and tested whether a type of extremophile found on Earth could grow on fragments of a meteorite from Mars.
    • Extremophiles are organisms that have adapted to survive in conditions in which most life forms cannot, such as ice, volcanoes, and space.
    • The results showed that the extremophiles were able to convert the rock into energy. What's more, the microbes left behind biosignatures that could help scientists identify evidence of past life on Mars.
