  • Researchers have proposed putting a plant-growth experiment on NASA's next Mars rover
  • scheduled to launch in mid-2020 and land on the Red Planet in early 2021.
  • known as the Mars Plant Experiment (MPX),
  • ...13 more annotations...
  • could help lay the foundation for the colonization of Mars,
  • its designers say
  • The MPX team
  • isn't suggesting that the 2020 Mars rover should
  • digging a hole with its robotic arm and planting seeds in the Red Planet's dirt.
  • the experiment would be entirely self-contained, eliminating the chance that Earth life could escape and perhaps get a foothold on Mars.
  • MPX would employ a clear "CubeSat" box
  • which would be affixed to the exterior of the 2020 rover
  • This box would hold Earth air and about 200 seeds of Arabidopsis, a small flowering plant that's commonly used in scientific research
  • The seeds would receive water when the rover touched down on Mars, and would then be allowed to grow for two weeks or so.
  • MPX would provide an organism-level test
  • how Earth life deals with the Red Planet's relatively high radiation levels and low gravity, which is about 40 percent as strong as that of Earth,
  • "It also would be the first multicellular organism to grow, live and die on another planet
