Fire Fountains on the Moon

This week on SciShow Space News, researchers have figured out which gas drives fire fountain eruptions on the Moon. And you can send a message or your name to the Moon or Mars!

mars in the modalities
  • fixed mars (taurus, leo, scorpio, aquarius):this is how it's going to be done
  • cardinal mars (aries, cancer, libra, capricorn):okay but i'm going to be the one to do it
  • mutable mars (gemini, virgo, sagittarius, pisces):uh i'll do whatever you're doing

NASA’s Next Nuclear-Powered Mars Rover: Building the Beast

NASA’s next nuclear-powered Mars rover, slated to launch in 2020, is slowly coming together. And while the Mars 2020 mission is largely based on NASA’s Mars rover Curiosity, which is now exploring the Red Planet, there are a variety of distinctions that set it apart.

NASA’s Mars 2020 rover mission is expected to explore a select site that’s geologically diverse, is likely to have been habitable and to seek out signs of past life.

But the rover is also slated to collect and stash Mars samples in tubes and drop them off at a preselected depot point. Years later, according to NASA’s plan, those Martian samples would be scooped up by a “ship and shoot” robotic mission to deliver the specimens back to Earth.

   This month, a mix of rover specialists and landing-site scientists met here to discuss the ambitious Mars 2020 mission during NASA’s second landing-site workshop for the flight. The meeting’s primary goal was to pare down a large number of candidate landing sites on Mars that emerged from the first workshop. Future landing-site meetings will eventually pick the winning exploration zone.

The meeting, which ran from Aug. 4 to Aug. 6, also served as a sort of show and tell time for engineers as they work ahead of key decisions that need to be made in designing the Mars 2020 robot.
