Neil Armstrong passed away this past Saturday at the age of 82. In addition to being the first man to walk on the moon, he was also the first photographer to set foot on that hunk of rock 238,900 miles away. Armstrong and fellow astronaut Buzz Aldrin snapped a total of 122 70mm color photographs using modified Hasselblad 500EL cameras during their short visit on July 21, 1969. However, not all of them were pretty.
American Photo magazine writes that the photographic record left by those two men shows a very human picture of that first landing. Some of the “dud” photos show accidental shutter preses, focusing errors, lens flare, and even photobombed landscape shots. Read more…
There’s an abandoned McDonalds in California that’s stuffed with 48,000 pounds of 70mm tape. These tapes contain never-before-seen ultra-high-res photographs of the moon shot by the Lunar Orbiter project 40 years ago. Rather than ship the film back to Earth, scientists decided to scan them on the spaceship, beam them back losslessly, and then record the data onto magnetic tape. Not wanting to reveal the precision of its spy satellites, the US government decided to mark the images as classified. Read more…
Ever wonder what camera gear NASA astronaut Don Pettit uses to shoot his amazing photographs from the International Space Station? Here’s a portrait of Don floating around on with his massive collection of Nikon DSLRs and lenses. How much of the gear can you identify?
It might not be very applicable to the vast majority of photographers, but NASA astronaut Captain Alan Pointdexter has written up a fascinating article over on Luminous Landscape in which he shares advice about doing photography in space. Taking photos on the ground is one thing, but imagine using not just the sun, but the earth itself as a source of light. Read more…
Here’s a fascinating video by NASA that explains what auroras are and what they look like from space. It’s filled with beautiful photographs and time-lapse sequences captured by astronauts on the International Space Station. Astronaut photographer Don Pettit, who maintains a blog about his experiences, writes that taking pictures of Earth is harder than it looks:
Even with a shutter speed of 1/1000th of a second, eight meters (26 feet) of motion occurs during the exposure. Our 400-millimeter telephoto lens has a resolution of less than three meters on the ground. Simply pointing at a target and squeezing the shutter always yields a less-than-perfect image, and precise manual tracking must be done to capture truly sharp pictures. It usually takes a new space station crewmember a month of on-orbit practice to use the full capability of this telephoto lens.
Another surprisingly difficult aspect of Earth photography is capturing a specific target. If I want to take a picture of Silverton, Oregon, my hometown, I have about 10 to 15 seconds of prime nadir (the point directly below us) viewing time to take the picture. If the image is taken off the nadir, a distorted, squashed projection is obtained. If I float up to the window and see my target, it’s too late to take a picture. If the camera has the wrong lens, the memory card is full, the battery depleted, or the camera is on some non-standard setting enabled by its myriad buttons and knobs, the opportunity will be over by the time the situation is corrected. And some targets like my hometown, sitting in the middle of farmland, are low-contrast and difficult to find. If more than a few seconds are needed to spot the target, again the moment is lost. All of us have missed the chance to take that “good one.” Fortunately, when in orbit, what goes around comes around, and in a few days there will be another chance.
This past Sunday, a group of amateur astronomers in San Antonio, Texas successfully “flashed” the International Space Station with a blue laser and spotlight as it whizzed by overhead. While this might sound like an easy thing to do, it’s much more complicated than you think. Astronaut Don Pettit shot the photo of the experiment seen above, and writes,
This took a number of engineering calculations. Projected beam diameters (assuming the propagation of a Gaussian wave for the laser) and intensity at the target had to be calculated. Tracking space station’s path as it streaked across the sky was another challenge. I used email to communicate with Robert Reeves, one of the association’s members. Considering that it takes a day, maybe more, for a simple exchange of messages (on space station we receive email drops two to three times a day), the whole event took weeks to plan.
The International Space Station maintains an orbital altitude of between 205 and 255 miles, so the fact that Pettit was able to see the flash of light from that distance is quite impressive.
Over the past year, there have been a number of jaw-dropping (and viral) time-lapse videos created from the amazing photos captured from the International Space Station by astronaut Mike Fossum. The video above provides an interesting behind-the-scenes look into how the images are captured.
Between August and October of this year, the crew onboard the International Space Station used a Nikon D3S (at high ISOs) to capture photographs of Earth as they zipped around it at 17,000mph. Michael Konig then took the footage and compiled it into this eye-popping time-lapse video showing what our planet looks like from up there. Read more…
This amazing image might look like a computer generated graphic, but it’s actually a composite photograph by NASA showing India’s population growth over the years. The white areas show the illumination visible in the country prior to 1992, while the blue, green, and red lights indicate new lights that became visible in 1992, 1998, and 2003, respectively. The four photos were tinted and then combined into an image that reveals where new populations are appearing. NASA definitely needs to do one for every country!
