Rare 1964 NASA 1000mm F4.5 super telephoto lens to be auctioned

17 Jun

A one-of-a-kind Birns and Sawyer Omnitar 1000mm f/4.5 lens commissioned by NASA in 1964 will soon be available to purchase through RR Auction. The lens is owned by Jim Headley, who introduced it to the public via Shutterbug. According to Headley, the lens weighs 70lbs / 32kg and measures 4ft / 1.2m in length by 10in / 25cm in diameter.

The super telephoto lens was built by Astra in Germany, and was acquired by Headley through a close friend after that friend closed down his camera store. Headly says on his website that he adapted the lens to work with a Canon EOS 40D, ‘effectively making this a 1600mm f:4.5 lens with the digital crop.’ The lens still features a pair of NASA identification tags, as well as a ‘trash can-sized’ lens shade. 

Headley plans to part with the giant lens, telling Shutterbug that it will be sold through an auction this fall by RR Auction in New Hampshire. Interested potential buyers can contact Jonathan Siefken at (603) 732-4280 for additional details.

Explore Mars with 360-degree image shot by NASA Curiosity Rover

11 Jun

Earlier this year, NASA released a 360-degree image from the perspective of the Curiosity Mars Rover. The scene is made up of a combination of multiple exposures taken with the rover’s 2MP ‘Mastcam’ camera, which we wrote about back in 2012.

The resulting image is pretty incredible, and if you have access to a Google Cardboard viewer you can experience it in 3D. So if you’ve got a free few minutes this weekend, why not explore the surface of Mars?

NASA astronaut Jeff Williams showcases ISS photography equipment

15 Apr

NASA astronaut and Expedition 47 flight engineer Jeff Williams posted a video recently detailing some of the equipment he uses to capture his incredible view of the planet from the International Space Station. So what kind of specialized gear does one use in space? Turns out the crew uses ‘regular photography equipment’ to capture still images and videos, with the Nikon D4 being one of several cameras used. A variety of lenses are used as well, including the massive 800mm lens (with 1.4x teleconverter, no less) shown in the video.

In addition to the photography equipment, Williams introduces viewers to the Cupola, the ‘window on the world’ that gives astronauts a full view of Earth from a single vantage point. Other windows are used to capture handheld photos and videos as well, and Williams explains that some videos are animated panoramas made from stitched still images.

You can see Williams’ photos on his Instagram and Facebook pages.

Dust on the lens or a new planet? NASA reveals some of its inter-galactic Photoshop tricks

01 Oct

In an interview for Adobe’s blog, NASA has revealed some of the processes its scientists use to transform technical data into images that the rest of the world can appreciate and understand. From simple tasks, such as straightening and cropping, to compositing multiple layers of scientifically calculated color, the agency uses programs including Adobe Photoshop to interpret the sometimes quite abstract images sent back to Earth from devices such as the Hubble Space Telescope and the Mars rover.

30 Frontier Finalists: NASA 3D-Printed Mars Habitat Shortlist

30 Sep

[ By WebUrbanist in Conceptual & Futuristic & Technology. ]

3d prints mars roving

A set of 30 candidates have been selected for final consideration by NASA in the 3D-Printed Habitat Challenge, including robot-constructed buildings, ice architecture and underground dwellings, all designed to turn challenges of building on Mars into opportunities. The three finalists shown below represent a subset of that range of compelling possibilities, varying in their approach to materials, automation and construction techniques.

3d printed shelters mars

3d printed mars habitats

3d interior mars dwellings

Foster + Partners proposes parachuting a series of task-specific, semi-autonomous robots to the surface, building out structures before the arrival of humans. These robotic helpers will dig holes, organize rocks and soil into building materials and use microwaves to fuse these components into place. More complex prefabricated components would then be installed into the system of resulting structures, preparing them for astronaut habitation.

ice mars habitat

The Ice House pitched by SEArch/Clouds Architecture Office offers connections between indoor and outdoor space via light filtered through frozen walls. Keeping NASA’s “follow the water” approach to space exploration in mind, the idea is to turn ice into a multilayered shell to enclose habitats and protected from radiation. “A unique 3D printing technique harnesses the physics of water and its phase transition to construct” structures.

inflatable mars habitat

The Mollusca L5  by LeeLabs combines inflatable shelters with fabricated structures made entirely from local surface materials. Sprawling organically like a slug, the habitat and storage areas are flexible and amorphous, combining hard walls and synthesized glass panels with soft cloth structures.

3d hybrid challenge shortlist

3d expanding habitat design

Common themes between projects include flexibility, modularity and redundancy – if either The Martian (a fictional story of a man lost on Mars) or Seveneves (in which humanity has to subsist in orbit for thousands of years) are any indication, surviving in space will mean facing challenges and overcoming obstacles through a combination of technology and ingenuity.

NASA employs 150-year-old photography technique to measure shock waves from supersonic flight

28 Aug

NASA has turned to a process devised in 1864 to help it measure shockwaves created by supersonic aircraft flight. The method, schlieren photography, was invented by German scientist August Toepler to observe the effect of objects moving through transparent media, such as water or air. Read more
