Microsoft’s HoloLens

Microsoft's HoloLens

Do you remember when Microsoft first introduced the Kinect? It was one the first times where I thought to myself that The Jetsons way of life may actually one day be a reality.

Well things just got a little more closer to that reality with Microsoft’s HoloLens. Instead of products like Google Glass and Oculus Rift, which put the user in a virtual world – the HoloLens puts you in a virtual environment by taking elements from a digital world and making them an interactive part of your world.

Farhad Manjoo of the New York Times had a chance to use it with Minecraft:

“In one demo, a Minecraft scene was displayed over a real living room. A Microsoft minder asked me to select a virtual hammer (a tool in the game) and start smashing the coffee table in the room. She wanted me, in other words, to use a digital object to interact with a real one. I did so and was stunned by what happened: Before my eyes, the real coffee table splintered into digital debris, and then it was no longer there. HoloLens had perfectly erased the coffee table from the environment.”

Here’s what Nick Statt of CNET had to say:

“Using real photography from the Curiosity rover, Microsoft was able to re-create a Martian landscape and overlay a 3D-map around a small, conference-room-size environment. I can walk around, bend down and look at rocks. I can even see NASA’s Curiosity rover, which is larger than a standard motor vehicle.”

“With HoloLens, I’m not just able to see what it’s like to walk around on Mars, but I’m also able to interact with the contents on the surface. Using a finger gesture called Air Tap, the HoloLens lets me mark certain spots on the surface for investigation and even lets me talk with another floating figure and collaborate on examining the surface.”

Lost Lunar Photos


The visual mood of the blog these days, especially the black and white images in Tim Navis’ new portfolio made me recall a post I saw on WIRED a few months ago.

Between 1966 and ’67, five Lunar Orbiters snapped pictures onto 70mm film from about 30 miles above the moon. The satellites were sent mainly to scout potential landing sites for manned moon missions. Each satellite would point its dual lens Kodak camera at a target, snap a picture, then develop the photograph. High- and low-resolution photos were then scanned into strips called framelets using something akin to an old fax machine reader.

View the complete set of photos and read the interesting story behind how the images were restored by the Lunar Orbiter Image Recovery Project here.

James Webb Space Telescope



Over twenty years in the making and set for a 2018 launch, the James Webb Space Telescope (JWST) is the single most advanced space telescope ever constructed. Successor to NASA’s beloved Hubble Space Telescope, JWST has been purpose-built for studying the infrared portion of the electromagnetic spectrum to give astronomers an ability of seeing past clouds of dust and gas and further back to the beginning of the Universe than we ever have. How far? According to NASA the JWST will see the Universe’s very first star formations taking place only 100 to 250 million years after the Big Bang. Such distant and precise observations promise to unleash a torrent of new discoveries and unlock fundamental quandaries about the origin of the cosmos and life in the Universe.

A few interesting facts:

• JWST’s primary mirror is a 6.5 meter diameter gold coated beryllium reflector that is too large for contemporary launch vehicles, so the mirror is being composed of 18 hexagonal segments (as seen above), which will all unfold after the telescope is launched. Why Hexagons? It’s beyond my comprehension, but supposedly this has something to do with hexagons having a perimeter less than that of a square over a given area, which translates to a gained efficiency for steering the mirror segments and focusing the telescope.

• The telescope will maintain an L2 orbit, meaning that it will orbit in earth’s shadow and around the sun, not the earth. The idea here is to eliminate all possible heat / light sources, such as Earth’s heat-shimmer, and keep the telescope as cold as possible. How cold? Extremely. Cold. The JWST’s mid-infrared instrument (MIRI) will operate at a set temperature of 7 Kelvins, or -266° C / -447° F, through the use of a helium refrigerator, or cryocooler system (source).

• Although JWST’s primary goal is to study the first galaxies or stars that formed after the Big Bang, the telescope is also capable of measuring the physical and chemical properties of planetary systems within our Milky Way and will investigate the potential for life in those planetary systems.

• When launched, some scientists suggest the telescope will represent a greater technological achievement than landing on the moon.

Saturn Hexagon


First discovered by the Voyager spacecraft in the early 1980s, NASA has recently released new images of the mysterious hexagon-shaped storm on Saturn’s northern pole. Taken with their Cassini Spacecraft, visible light images like this were not originally possible when Cassini arrived at Saturn back in 2004 due to the entire northern hemisphere being in winter solstice.


The hexagon measures 25,000 km (15,500 mi) across, with each side being 13,800 km (8,600 mi) long. As the above image demonstrates, it’s wide enough to fit nearly four earth’s inside of it.


The hexagonal ring itself is created by a jet stream, while the center contains a spiralling vortex of clouds. Scientists say that the storm reaches speeds up to 354 km/h (220 mph).


In short, we can’t figure it out. Namely, scientists don’t currently understand where the storm obtains and expels its energy, or how/why it has stayed in such an organized shape for so long.

Misfits: From the Moon


Here are the lesser-known photos from NASA’s Apollo program, too sun-burned or out-of-focus to make it to mainstream, uncovered after many hours of browsing the Apollo Archive.
