Scientists continue grappling with fundamental mysteries of gravity, from the precise value of the gravitational constant to unexplained experimental results sealed away for a decade. NASA's Psyche mission is leveraging gravitational assists to navigate the solar system while researchers worldwide investigate how gravity shapes everything from planetary orbits to zero-gravity environments.
·NIST researchers are working to resolve ongoing uncertainty about the gravitational constant's exact value
·Decade-old sealed experimental results reveal gravity still defies complete scientific explanation
·NASA's Psyche mission uses Mars gravity assist maneuvers to optimize its trajectory
·Experiments demonstrate how weightlessness and zero gravity function in Earth's orbital environment
·Orbital mechanics show how gravitational forces govern planetary motion around the sun
