This image from InSight’s robotic-arm mounted Instrument Deployment Camera shows the instruments on the spacecraft’s deck, with the Martian surface of Elysium Planitia in the background. The color-calibrated picture was acquired on December 4, 2018 (Sol 8); in the foreground, a copper-colored hexagonal cover protects the SEIS seismometer; the gray dome behind SEIS is the wind and thermal shield, which will be placed over SEIS; to the left is a black cylindrical instrument, the Heat Flow and Physical Properties Probe (HP3); HP3 will drill up to 16 feet (5 m) below the Martian surface, measuring heat released from the interior of the planet; above the deck is InSight’s robotic arm, with the stowed grapple directly facing the camera; to the right can be seen a small portion of one of the two solar panels that help power InSight and part of the UHF communication antenna.

The current, widely recognized model of the Universe, called LambdaCDM, tells us nothing about what dark matter and dark energy are like physically. We only know about them because of the gravitational effects they have on other, observable matter. Dr. Farnes’ model offers a new explanation. Image credit: NASA / ESA / M.
