No mission to Mars has done what InSight will do. The lander’s spectacularly sensitive instruments will use the Red Planet’s heat and marsquakes to reveal its deep interior while also revealing secrets of other rocky worlds like our own Earth. Principal Investigator Bruce Banerdt came to Planetary Society headquarters barely a week before launch for a long and fascinating conversation. Planetary Society CEO Bill Nye says the European Space Agency’s Gaia spacecraft has mapped our galaxy as never before. Bruce Betts will help us explore a bit of the Milky Way in this week’s What’s Up segment.

InSight nearly ready for launch
At the Astrotech payload processing facility at Vandenberg Air Force Base on April 6, 2018, engineers readied InSight for launch. The spacecraft is in launch configuration, upside down with landing legs tucked against the body, packed inside its backshell. Red caps cover the landing rockets, which are pointed up. The backshell is, in turn, attached to the cruise stage. The remaining step is to cap the assembly with a heat shield.
