First unchained spacewalk was made on this day
The world's first ever unchained spacewalk was made by Captain Bruce McCandless and Colonel Robert Stewart on February 7, 1984. They walked freely for 5 hours 55 minutes and orbited the Earth in tangent with their space shuttle 'Challenger' moving at a speed of over 17,500 miles/hour. The duo flew up to 320 feet away from the space shuttle.
