>>On VRD, I read a paper some time ago that asserted that VRD was the only display technology that had the capability of completely fooling the brain into believing that the images were actually there. Question .... On vehicles such as a Mars lander, are images captured with a stereoscopic view, or are they still mono?<<<
IMP Camera of the Rover on Mars Pathfinder Mission
Azimuth and elevation drives for the camera head are provided by stepper motors with gear heads, providing a field of regard of ñ180 degrees in azimuth and +83 degrees to -72 degrees in elevation, relative to lander coordinates. The camera system is mounted at the top of a deployable mast, a continuous longeron,open-lattice type provided by Able Manufacturing, Inc. When deployed, the mast provides an elevation of 1.0 m above the lander mounting surface.
The focal plane consists of a CCD mounted at the foci of two optical paths where it is bonded to a small printed wiring board, which in turn is attached by a short flex cable to the preamplifier board. The CCD is a front-illuminated frame transfer array with 23 micrometer square pixels. Its image section is divided into two square frames, one for each half of the stereo FOV's. Each has 256x256 active elements. A 256x512 storage section (identical to the imaging section) is located under a metal mask. The imp focal plane and electronics
are nearly identical copies of the comparable subsystem employed in the Huygens Probe Descent Imaging Spectroradiometer (DISR), using the Loral 512X512 CCD.
The stereoscopic imager includes two imaging triplets, two fold mirrors separated by 150 mm for stereo viewing, a 12-space filter wheel in each path, and a fold prism to place the images side-by-side on the CCD focal plane. Fused silica windows at each path entrance prevent dust intrusion. the optical triplets are an f/10 design, stopped down to f/18 with 23-mm effective focal lengths and a 14.4 degree field of view. The pixel instantaneous field of view is one milliradian. The filter wheel four pairs of atmospheric filters, two pairs of stero filters, eleven individual geologic filters (which, when combined with the two pairs of stereo filters, result
in thirteen distinct geologic filters) and one diopter or close-up lens, designed to acquire images of magnetic, wind-blown dust which adheres to a small magnet located on the imp tip plate.
Full panoramas of the landing site are acquired during the mission using the stereo baseline provided by the camera optics. Additionally, monoscopic panoramas are acquired both prior and subsequent to the mast deployment, yielding vertically displaced stereo pairs with approximately 80 cm baseline. Images of a substantial portion of the visible surface are acquired in multispectral images with as many as eight spectral bands.

December 4, 1996, Cape Canaveral. Mars Pathfinder
was successfully launched at 1:58 am EST
10:58 pm PST) on a Delta II rocket from Pad 17b at
the Cape Canaveral Air Station. It is now on its way to
Mars and will arrive on July 4, 1997!

Where I work, actually my building is out of the picture to the right.
Thats the Atlantic Ocean on the far right, The Banana River in the middle, and the Indian River in the left.
My house is in the picture too.

The VAB is the 2nd Largest Building in the World
The Crawler that moves the Shuttle is no Slouch itself. Compare it's size to the Cars on the left. Each section of Tread (Like an Army Tanks) weighs over a Ton!
Crawler Transporter Statistics
Weight: 2,721 metric tons (6 million pounds)
Length: 40 meters (131 ft) wide, 35 meters (114ft) long
Miles: 2,526 miles (1,243 miles since 1977)
The KSC crawlers are the largest tracked vehicles known. They move the Mobile Launcher Platform into the Vehicle Assembly Building and then to the Launch Pad with an assembled space vehicle. Maximum
speed is 1.6km (one mile) per hour loaded, about 3.2 km (2 miles) per hour unloaded. Launch Pad to VAB trip time with the Mobile Launch Platform is about 5 hours. The crawler burns 568 liters (150
gallons) of diesel oil per mile.

If you turn the Air Conditioners off in the VAB, Clouds would form,
and it would rain inside. (Something I remembered from the Apollo Days)
