Bruce McCandless: Floating Astronaut in Space


NASA has had a great knack for producing awe-inspiring images. In its history of space exploration, the most jaw-dropping photographs are usually those that involve stars and galaxies thousands of light-years away. A few other great images, however, are much closer to home. In this iconic image of a lonely spaceman stuck between earth and nothingness, NASA was able to successfully perform a free spacewalk for the very first time. This is the story of Bruce McCandless and the photograph of the floating astronaut in space.

The flying spaceman in the picture is Captain Bruce McCandless II, credited for having made the first untethered free flight in space. Previously, and even now, any Extra-Vehicular Activities (EVAs) performed by astronauts were done so with a tether. Spacewalks were thus limited to the length of the tether. With the new Manned Maneuvering Unit (MMU), spacewalks could be performed untethered.

The free flight was done on February 12, 1984 with the nitrogen jet backpack. McCandless traveled some 320 feet away from the space shuttle Challenger, farther than any astronaut had attempted ever before. The resulting view showed a small astronaut against the blackness of space and the pale blues and whites of the earth.

Jumping Off a Cliff... into Space


Staying with the space related theme from the previous article, today's post ventures a little bit past Earth's atmosphere to show you the first NASA spacewalk.

The amazing photograph above shows astronaut Ed White, pilot of NASA's Gemini 4 mission, on the first ever US spacewalk or more technically speaking, extra-vehicular activity. This wasn't the first occasion of an EVA as the honor of the first ever space walk goes to cosmonaut Alexey Leonov.

Even without going into details of how this photograph was made, this is an amazing image every time you look at it; a close crop of a free floating spaceman against the darkness of space on one side and the vibrant blue Earth on the other side.

Symbolically speaking, the tether attached to the astronaut looks more like an umbilical cord, and the whole scene is evocative of man's attempt to free itself of the binding ties to its mother Earth. With all of the advancements of man at that time and even with the purportedly coming Singularity a few decades away, the photo somehow shows that humans are still grounded in some way and will never be entirely free of their physical limitation. 

While the image is truly iconic, it is sad to note that astronaut Ed White died in the Apollo 1 cabin fire. The memory of his life and work will live on in this great picture.

This image is also taken from the NASA Goddard Space Flight Center Photostream. If you want a larger resolution file of this US spacewalk photo, you can find it here.
