Check your gravity with NASA's Artemis II zero-g indicator

NASA's Artemis II zero-g indicator lets anyone with a smartphone check their own gravity using a small, weightless token aboard the Orion spacecraft. This interactive tool, costing $0 for public use, will float during the 10-day lunar mission, and users can compare their local gravitational pull via an app that measures deviation from Earth's 9.8 m/s² standard. The token, designed by students, weighs just 3.2 ounces and serves as a real-time connection to the 2025 moon shot, which will carry four astronauts. It's a clever outreach piece, yet its impact pales against the geopolitical stakes of space exploration.
