You probably don’t know this, but February 12th, 1984 was an incredible day for space exploration.
No, we didn’t discover a new galaxy, or make a huge technological advancement in the area of extraterrestrial communication. However, an astronaut did attempt the first-ever exploratory maneuver that took him further away from his ship than had ever been attempted.
This was made possible by a nitrogen jet-propelled backpack, which was an incredibly new device at the time. Astronaut Bruce McCandless ventured an amazing 320 feet away from his ship, without a tether.
