Lunar Images From Chandrayaan-1

Lunar Images From Chandrayaan-1
“This is the picture of moon’s surface taken from lunar orbit by Chandrayaan-1 spacecraft’s Terrain Mapping Camera (TMC) on November 15, 2008. Taken over the polar region of the moon, the picture shows many large and numerous small craters. The bright terrain on the lower left is the rim of 117 km wide Moretus crater.”

Retrieving Lunar Orbiter Images

This video shows a Lunar Orbiter image framelet being retrieved from an original data tape using a restored FR-900 tape drive. Watch the monitor between the two tape drives as portions of the image (negative image) roll across the screen. This activity is part of the Lunar Orbiter Image Recovery Project (LOIRP) underway at NASA ARC.

How the Photo Was Taken

This chart from the 1960’s shows the context of the newly restored Lunar Orbiter 1 image. This image was taken on 23 August 1966 and restored by the Lunar Orbiter Image Recovery Project at NASA Ames Research Center. The orientation of Earth was slightly off and shows a terminator about an hour off from what is actually in the image.Larger image. Credit: NASA/LOIRP

This graphic shows the actual orientation of Earth at the time the photo was taken. It was possible to match the outlines of north Africa in the newly restored image. Larger image. Credit: NASA/LOIRP

Seeing Clouds Shadows On Earth

This graphic compares the enhanced resolution of the LOIRP image and the highest resolution image available online at LPI. AT full resolution shadows can be seem between clouds and the Earth’s surface at a resolution estimated to be around 1 kilometer per pixel.

Comparing USGS and LOIRP Image Resolution

Several years ago the USGS Astrogeology Research Program began a project whereby copies of original Lunar Orbiter photos have been scanned using high resolution scanning devices.

NASA Unveils 42-Year-old Historic Lunar Image

MOFFETT FIELD, Calif. – NASA will hold a media briefing at 3 p.m. PST on Thursday, Nov. 13, 2008, to unveil a newly restored historic image from the early days of lunar exploration and discuss the innovative processing technique used to retrieve the image.
The briefing will take place in the Ames Research Center auditorium, Bldg. N-201. NASA officials will be available to discuss the recovery process and the scientific value of the iconic images to the next generation of explorers as NASA plans to return to the moon. A tour of the restoration facility will be offered following the briefing.
Briefing participants are:
– S. Pete Worden, Ames Research Center Director
– Greg Schmidt, Deputy Director, NASA Lunar Science Institute, NASA Ames
– Dennis Wingo, Image Recovery Project Lead, Huntsville, Ala.
– Charles J. Byrne, Lunar Image Expert, Middletown, N.J.
For news media representatives unable to attend, a roundtable discussion will be held following the briefing. Reporters wanting to participate must call Mike Mewhinney at 650-604-3937 by Wednesday, Nov. 12, 2008.
Driving Directions: To reach NASA Ames, take the Moffett Field/NASA Parkway exit off U.S. 101 and drive east on Moffett Boulevard towards the main gate. At the main gate, pull into the small parking lot on your right and enter the Visitor Badge Office to obtain a visitor pass. The auditorium is located directly behind the administration building as you enter the center.

Man’s First Look at Earth From the Moon….

NASA SP-168 EXPLORING SPACE WITH A CAMERA
ORBITER I
Describing the spectacular, historic view above, FLOYD L. THOMPSON, then Director, Langley Research Center, wrote: “At 16:35 GMT on August 23, 1966, the versatile manmade Lunar Orbiter spacecraft responded to a series of commands sent to it from Earth, across a quarter-million miles of space, and made this over-the-shoulder view of its home planet from a vantage point 730 miles above the far side of the Moon.
“At that moment,” Thompson continued, “the Sun was setting along an arc extending from England [on the right] to Antarctica [on the left]. Above that line, the world, with the east coast of the United States at the top, was still bathed in afternoon sunlight. Below, the major portion of the African Continent and the Indian Ocean were shrouded in the darkness of evening. “By this reversal of viewpoint, we here on the…
… and an Oblique View of the Moon Itself
….Earth have been provided a sobering glimpse of the spectacle of our own planet as it will be seen by a few of our generation in their pursuit of the manned exploration of space. We have achieved the ability to contemplate ourselves from afar and thus, in a measure, accomplish the wish expressed by Robert Burns: ‘To see oursels as ithers see us! ”
Also visible in dramatic new perspective in this photograph is the singularly bleak Iunar landscape, its tortured features evidently hammered out by a cosmic bombardment that may have extended over billions of years.
Because the airless, weatherless Moon appears to preserve its surface materials so well, it may serve science as an illuminating record of past events in the solar system. ROBERT JASTROW, Director Goddard Institute for Space Studies, has called the Moon “the Rosetta Stone of the planets.”

Lunar Orbiter Imagery and Apollo Landing Site Selection

Source: Apollo Expeditions to the Moon Chapter 5.5 – Mapping and Site Selection
Meanwhile the third member of the automated lunar exploration team had already completed its work. The fifth and last Lunar Orbiter had been launched on August 1, 1967, nearly half a year earlier. When JPL and Hughes began to experience difficulties with Surveyor development, and with the Centaur in deep trouble, NASA decided to back up the entire proaram with a different team and different hardware. The Surveyor Orbiter concept was scrapped, and NASA’s Langley Research Center was directed to plan and carry out a new Lunar Orbiter program, based on the less risky Atlas-Acena D launch vehicle. Langley prepared the necessary specifications and Boeing won the job. Boeing’s proposed design was beautifully straightforward except for one feature, the camera. Instead of being all-electronic as were prior space cameras, the Eastman Kodak camera for the Lunar Orbiter made use of 70-mm film developed on board the spacecraft and then optically scanned and telemetered to Earth. Low-speed film had to be used so as not to be fogged by space radiation. This in turn required the formidable added complexity of image-motion compensation during the instant of exposure. Theoretically, objects as small as three feet could be seen from 30 nautical miles above the surface. If all worked well, this system could provide the quality required for Apollo, but it was tricky, and it barely made it to the launch pad in time to avoid rescheduling.

A photo of the crater on the Moon,Tycho

The youngest big crater on the Moon is Tycho, which is about 53 miles across and nearly 3 miles deep. These Orbiter V photographs reveal its intricate structure. (Area in the rectangle above is pictured in higher resolution below.) A high central peak arises from the rough floor, and the crater wall has extensively slumped. The comparative scarcity of small craters within Tycho indicate its relatively recent origin. Flow features seen in both pictures could have been molten lava, volcanic debris, or fluidized impact-ejected material. Surveyor VII landed about 18 miles north of Tycho, in the area indicated by the white circle above. Enlargements of these pictures show an abundance of fissures and large fractured blocks, particularly near the uppermost wall scarp.
