NEW YORK (NYTIMES) - Bruce McCandless, the first person to fly untethered in space and whose journey into the dark void above Earth was preserved in an iconic photograph, died on Thursday (Dec 21). He was 80.
Nasa announced his death in a statement on Friday but did not provide more details.
Equipped with a bulky backpack, two dozen tiny jet thrusters and two bottles of nitrogen gas to fuel them, McCandless took his maiden voyage in February 1984. It was captured in an image of a man in a white space suit floating against a backdrop of the great black abyss.
A front-page article in The New York Times called McCandless' ascent "a spectacle of bravery and beauty". McCandless and another astronaut, Robert L. Stewart, the article said, had effectively become "the first human satellites", orbiting the Earth at the same velocity as the nearby shuttle - 28,164kmh.
"That may have been one small step for Neil, but it's a heck of a big leap for me," McCandless joked at the time, in reference to comments Neil Armstrong made after taking the first human step on the moon in 1969.
One of 19 people selected by Nasa to become astronauts in April 1966, McCandless, a former US Navy captain, would play a role in Armstrong's famed moonwalk only three years later.
McCandless, in mission control, was the voice the world heard communicating with Armstrong and Buzz Aldrin during their Apollo 11 mission. At one point, Armstrong remarked that their view of the moon was "really spectacular" and "worth the price of the trip". About 15 years before he would roam through space himself, McCandless replied, "Well, there are a lot of us down here that would be willing to come along."
McCandless would spend another decade helping develop the technology - called "manned manoeuvring units" - that would eventually allow him to float free in space at the age of 46.
That 1984 mission had various technical objectives, but it was McCandless' inaugural spacewalk that captured the hearts and minds of those about 274km below. The Times described McCandless as "a puffy white gingerbread man" floating above the continental United States.
"This is neat," he said, before peering down.
"Looks like Florida. It is Florida!" he exclaimed, remarking later that the panorama "really is beautiful". During his second space shuttle mission, in 1990, McCandless helped deploy the Hubble Space Telescope. By the end of his career, he had logged more than 300 hours in space, including four hours in a manned manoeuvring unit, according to his Nasa biography.
Bruce McCandless II was born on June 8, 1937, in Boston, into a family of high-ranking naval officers. He graduated from Woodrow Wilson Senior High School in Long Beach, California, and received a Bachelor of Science degree from the US Naval Academy in 1958. He later earned two master's degrees - one in electrical engineering from Stanford University and another in business administration from the University of Houston at Clear Lake City.
He received several honours throughout his career from the Defence Department, Nasa and the Smithsonian Institution. He was also awarded a patent for his role in designing what Nasa said was "a tool tethering system" used during spacewalks.
McCandless is survived by his wife, Ellen Shields McCandless; his son, Bruce McCandless III; his daughter, Tracy McCandless; a brother, Douglas M. McCandless; two sisters, Sue M. Woodridge and Rosemary V. McCandless; and two granddaughters.
While reflecting on that famous photograph in The Guardian in July 2015, McCandless noted that his visor was down.
"My anonymity means people can imagine themselves doing the same thing," he said. "Like Neil said in 1969, I was representing mankind up there."
