    Episode 639: Waterworlds. Can There Be Life Without Land?

    Episode 639: Waterworlds. Can There Be Life Without Land?

    One of the longstanding questions astronomers have had is, are we normal? Is our Solar System a template for what we might expect to see as we look out into the Milky Way at other star systems?


    As the data continues to come in, the answer to that question really seems to be no, we’re not normal. Star systems seem to have a huge variety of planets orbiting them. Familiar planets like our own terrestrial, gas and ice worlds. But then there are also super earths, mini-neptunes, hot jupiters.


    And it looks like there are planets, located in their star’s habitable zone, which are completely covered with liquid water. Like, oceans which are dozens and maybe even hundreds of kilometers deep.


    What would it be like on one of these worlds, and of course, we always want to know, could they be habitable?

    Episode 635: Japan is Going to Bring a Sample of Phobos Back to Earth. The Martian Moon eXploration Mission

    Episode 635: Japan is Going to Bring a Sample of Phobos Back to Earth. The Martian Moon eXploration Mission

    Mars has been the destination for so many of our spacecraft, and for good reason, it’s probably the most Earthlike place in the Solar System, with water ice on its surface and reservoirs of the liquid beneath the surface. If we’re going to find life, Mars might be the place.


    But the tiny moons orbiting Mars, Phobos and Deimos, are scientifically fascinating on their own, and so far, a mission has never reached them.


    Last week, Japan announced that they’ve greenlit their Martian Moon eXploration mission, or MMX, which will launch an orbiter, lander and maybe even a rover to Phobos in 2024, returning samples back to Earth by the end of the decade.
