Galactic cosmic rays are high energy particles from explosive events like supernovae, zinging through our solar system, constantly bombarding both Earth and Mars. A researcher suggests they supply enough energy to make subsurface life on Mars possible.

After the Soyuz MS-14’s first automated approach to the ISS was aborted due to a malfunction, the spacecraft has now docked safely at the station’s Zvezda module. It carries supplies for the crew and a humanoid robot.

Tomorrow, the spacecraft will shift from its orbit of Earth toward a path to the moon.
