📅 **February 7, 1984** – The world’s first untethered spacewalk.
On this day, **NASA astronaut Bruce McCandless II** became the first person to conduct a spacewalk without a tether, floating freely in the vastness of space.
Equipped with the **Manned Maneuvering Unit (MMU)**—a jetpack-like system with gas thrusters—McCandless was able to venture **320 feet away from the Space Shuttle Challenger**, marking a historic moment in human spaceflight.
This daring mission demonstrated new possibilities for satellite servicing, station assembly, and future deep-space exploration.
**A salute to McCandless and all pioneers who push the limits of exploration!** 🛰️🇺🇸
