Mars in 3D

Mars in 3D

I generally look at the Astronomy Picture of the Day on a daily basis. Last week, I saw this anaglyph taken by the Mars Pathfinder back in 1997. It shows the Martian landscape and some local artifacts in stereoscopic perspective. Sorry, there is no 2D image available without me digging through NASA and JPL archives, so you better get a pair of 3D glasses to enjoy the image in full perspective.

From APOD:

From July of 1997, a ramp from the Pathfinder lander, the Sojourner robot rover, airbags, a couch, Barnacle Bill and Yogi Rock appear together in this 3D stereo view of the surface of Mars. Barnacle Bill is the rock just left of the solar-paneled Sojourner. Yogi is the big friendly-looking boulder at top right. The “couch” is the angular rock shape visible near center on the horizon. Look at the image with red/blue glasses (or just hold a piece of clear red plastic over your left eye and blue or green over your right) to get the dramatic 3D perspective. The stereo view was recorded by the remarkable Imager for Mars Pathfinder (IMP) camera. The IMP had two optical paths for stereo imaging and ranging and was equipped with an array of color filters for spectral analysis.

Hassayampa River in 3D

river3d.jpg

It’s been quite a while since I posted an anaglyph photo. Verna took an image pair of the riverbed way back in November of 2015 as we crossed the bridge over the Hassayampa River. I combined the images into the 3D anaglyph above. Click on the image to enlarge.

The river is dry above ground most of the year and looks as it does in this image or in its 2D counterpart (at the link in case you don’t have red/cyan glasses). During monsoon season or at other very heavy rainfall periods, this river gets quite full and flows with vigor downstream. This view is looking toward the north and upstream.

Apollo 12 Crew Visits Lunar Surveyor Spacecraft - 3D

Lunar Anaglyph

Fifty years ago, there were men walking on the moon. This 3D photo of Pete Conrad jiggling the surveyor lunar lander was taken by Alan Bean in two images merged into a red-cyan anaglyph image. Click on the image to enlarge.

Not mentioned in the below Article from APOD was the fact that the astronauts brought back the robotic scoop from the spacecraft which I later saw in a display window in Building 5 at the Hughes Aircraft Facility in Culver City, CA.

This is the blurb from APOD:

Put on your red/blue glasses and gaze across the western Ocean of Storms on the surface of the Moon. The 3D view features Apollo 12 astronaut Pete Conrad visiting the Surveyor 3 spacecraft 50 years ago in November of 1969. Surveyor 3 had landed at the site on the inside slope of a small crater about 2 1/2 years earlier in April of 1967. Visible on the horizon beyond the far crater wall, Apollo 12’s Lunar Module Intrepid touched down less than 200 meters (650 feet) away, easy moonwalking distance from the robotic Surveyor spacecraft. The stereo image was carefully created from two separate pictures (AS12-48-7133, AS12-48-7134) taken on the lunar surface. They depict the scene from only slightly different viewpoints, approximating the separation between human eyes.

Of course, if you don’t yet have your free pair of 3D glasses to view the image above, you can see the 2D version here.

Helene, a Trojan Moon of Saturn In 3D

Helene

Today’s Astronomy Picture of the Day featured this interesting 3D image of Helene, one of the planet Saturn’s Trojan moons. From APOD:

Explanation: Get out your red/blue glasses and float next to Helene, small, icy moon of Saturn. Appropriately named, Helene is one of four known Trojan moons, so called because it orbits at a Lagrange point. A Lagrange point is a gravitationally stable position near two massive bodies, in this case Saturn and larger moon Dione. In fact, irregularly shaped ( about 36 by 32 by 30 kilometers) Helene orbits at Dione’s leading Lagrange point while brotherly ice moon Polydeuces follows at Dione’s trailing Lagrange point. The sharp stereo anaglyph was constructed from two Cassini images captured during a close flyby in 2011. It shows part of the Saturn-facing hemisphere of Helene mottled with craters and gully-like features.

Lava Falls on Mars in 3D

Lava Falls on Mars

Today’s Astronomy Picture of the Day is an image rendered in stereo taken by a Martian satellite. The depth of this image when using the red/cyan glasses is pretty amazing.

From APOD:

This stereo anaglyph was created by combining two images recorded by the HiRISE camera onboard Mars Reconnaissance Orbiter. The multi-level falls were created as flowing lava breached sections of the northern rim of a 30-kilometer diameter martian crater, located in the western part of the Red Planet’s volcanic Tharsis region. As the molten lava cascaded down the crater wall and terraces to reach the crater floor it left the distinctly rough, fan-shaped flows on the steeper slopes. North is up and the breathtaking 3D view is 5 kilometers wide.

Maximizing the RV Parking Spot

Patio Clearance 3D

I figured a good way to demonstrate how close the new RV fits into the parking spot was to take a 3D image pair showing the overlap between the RV, the patio and the RV bedroom slide out. Click on the image to enlarge.

Here are a couple of images showing the RV parked in the barely big enough parking space with slide-outs and awning deployed: image 1, image 2.

From the other blog:

Now, we have upgraded to a Class A diesel pusher which is just about the shortest in the diesel category at 35 feet nine inches. We have three slide outs and an 18 foot awning, all of which can be deployed in the space available behind the garage. But just barely.

Of course, if you don’t yet have your free pair of 3D glasses to view the image above, you can see the 2D version here.

Comet Churyumov-Gerasimenko in 3D

Comet in 3D

Today’s Astronomy Picture of the Day featured an anaglyph image of Comet Churyumov-Gerasimenko taken by the Rosetta comet-probing spacecraft. I was impressed by the stereo image of this object in space in an up-close and personal view of another world.

From APOD:

Get out your red/cyan glasses and gaze across the surface of Churyumov-Gerasimenko, aka Comet 67P. The stereo anaglyph was created by combining two images from the Rosetta spacecraft’s narrow angle OSIRIS camera taken on September 22, 2014. Stark and jagged, the 3D landscape is found along the Seth region of the comet’s double-lobed nucleus. It spans about 985 x 820 meters, pocked by circular ridges, depressions, and flattened areas strewn with boulders and debris. The large steep-walled circular pit in the foreground is 180 meters in diameter. Rosetta’s mission to the comet ended in September 2016 when the spacecraft was commanded to a controlled impact with the comet’s surface.
