Vikram Lander Wreckage Found on Lunar Surface

GREENBELT, Md. (NASA PR) — The Chandrayaan 2 Vikram lander was targeted for a highland smooth plain about 600 kilometers from the south pole; unfortunately the Indian Space Research Organisation (ISRO) lost contact with their lander shortly before the scheduled touchdown (Sept. 7 in India, Sept. 6 in the United States).  Despite the loss, getting that close to the surface was an amazing achievement.

The Lunar Reconnaissance Orbiter Camera team released the first mosaic (acquired Sept. 17) of the site on Sept. 26 and many people have downloaded the mosaic to search for signs of Vikram. Shanmuga Subramanian contacted the LRO project with a positive identification of debris. After receiving this tip, the LROC team confirmed the identification by comparing before and after images.

This before and after image ratio highlights changes to the surface; the impact point is near center of the image and stands out due the dark rays and bright outer halo. Note the dark streak and debris about 100 meters to the SSE of the impact point. Diagonal straight lines are uncorrected background artifacts. (Credits: NASA/Goddard/Arizona State University)

When the images for the first mosaic were acquired the impact point was poorly illuminated and thus not easily identifiable. Two subsequent image sequences were acquired on Oct. 14 and 15, and Nov. 11.

The LROC team scoured the surrounding area in these new mosaics and found the impact site (70.8810°S,  22.7840°E, 834 m elevation) and associated debris field. The November mosaic had the best pixel scale (0.7 meter) and lighting conditions (72° incidence angle).

Before and after images show the Vikram impact point. Changes to the surface are subtle and are more easily seen in the ratio image presented above. (Credits: NASA/Goddard/Arizona State University)

The debris first located by Shanmuga is about 750 meters northwest of the main crash site and was a single bright pixel identification in that first mosaic (1.3 meter pixels, 84° incidence angle). The November mosaic shows best the impact crater, ray and extensive debris field. The three largest pieces of debris are each about 2×2 pixels and cast a one pixel shadow.

Moon Village Principles – Mission Prize 2019

VIENNA, Austria, November 19, 2019 (MVA PR) — The Moon Village Association (MVA) announces the winners of the Moon Village Principles – Mission Prize 2019.

In December 2018, the Moon Village Association (MVA) had published a new concept named the “Moon Village Principles”. The Moon Village Principles represent a clear statement of the MV Association’s vision of how missions and other activities focused on the Moon, might most effectively contribute to realization of the Moon Village concept. This includes key areas such as acquiring knowledge of the Moon, establishing standards, proving important technologies, engaging the public and others.

LRO Fails to See Vikram on Lunar Surface Obscured by Shadows

The area where India’s Vikram spacecraft had a hard landing was captured by the Lunar Reconnaissance Orbiter Camera (LROC) Quickmap during a fly-around of the targeted landing site. The image width is about 150 kilometers across the center. (Credits: NASA/Goddard/Arizona State University)

GREENBELT, Md. (NASA PR) — The Chandrayaan-2 lander, Vikram, attempted a landing Sept. 7 (Sept. 6 in the United States), on a small patch of lunar highland smooth plains between Simpelius N and Manzinus C craters. Vikram had a hard landing and the precise location of the spacecraft in the lunar highlands has yet to be determined.

The lander, Vikram, was scheduled to touch down on Sept. 6 at 4:24 pm Eastern Daylight Time. This event was India’s first attempt at a soft landing on the Moon. The site was located about 600 kilometers (370 miles) from the south pole in a relatively ancient terrain (70.8°S latitude, 23.5°E longitude). In order to visualize the site, take a quick fly-around.

The Lunar Reconnaissance Orbiter (LRO) passed over the landing site on Sept. 17 and acquired a set of high resolution images of the area; so far the LROC team has not been able to locate or image the lander.  It was dusk when the landing area was imaged and thus large shadows covered much of the terrain; it is possible that the Vikram lander is hiding in a shadow.

A wide view of a series of Lunar Reconnaisance Orbiter Camera’s narrow angle camera images collected on Sept. 17 showing the area of the targeted Vikram landing site. The pixel scale is 28314 pixels by 1041 lines. The resolution is 34 meters per pixel. The full resolution mosaic can be found at: http://lroc.sese.asu.edu/posts/1128. Note this mosaic is quite large (28314 pixels by 57851 lines) with approximately 900 million illuminated pixels (1.25 meter pixels, 1000 meter grid, polar stereographic projection).

The lighting will be favorable when LRO passes over the site in October and once again attempts to locate and image the lander.

It’s Dead, Jim! ISRO Gives Up on Lunar Lander, Rover

Well, it’s not the famous winter of Game of Thrones, but the 14-day lunar night has arrived where India’s Vikram lander and Pragyan rover made what IRSO officials have called a “hard landing” two weeks ago with no communication between them and ground controllers.

Since neither vehicle was designed to survive the frigid temperatures of the lunar night, the Indian space agency has called it a day in a rather bare bones announcement.

Half a century ago, Apollo 8 ushered in a new era of space exploration. The missions that followed in close succession would herald these breakthroughs in science and in engineering prowess with drama and color. They would bring a cornucopia of knowledge about the Moon, the origins of our solar system, the nature of our universe, the history of our Earth and even the history of life. In addition to tangible, scientific assets gained from Apollo, the mission brought some degree of unification to a nation fractured by conflict at home and abroad.

GREENBELT, Md. (NASA PR) — On Oct.13, 2014 something very strange happened to the camera aboard NASA’s Lunar Reconnaissance Orbiter (LRO). The Lunar Reconnaissance Orbiter Camera (LROC), which normally produces beautifully clear images of the lunar surface, produced an image that was wild and jittery. From the sudden and jagged pattern apparent in the image, the LROC team determined that the camera must have been hit by a tiny meteoroid, a small natural object in space.

GREENBELT, Mary. (NASA PR) — While the moon’s surface is battered by millions of craters, it also has over 200 holes – steep-walled pits that in some cases might lead to caves that future astronauts could explore and use for shelter, according to new observations from NASA’s Lunar Reconnaissance Orbiter (LRO) spacecraft.

The pits range in size from about 5 meters (~5 yards) across to more than 900 meters (~984 yards) in diameter, and three of them were first identified using images from the Japanese Kaguya spacecraft. Hundreds more were found using a new computer algorithm that automatically scanned thousands of high-resolution images of the lunar surface from LRO’s Narrow Angle Camera (NAC).

LRO Reveals Moon in New Ways

New maps of lunar surface characteristics LOLA data give us three complementary views of the near side of the moon: the contours of the landscape, or topography (left), along with new maps of the surface slope values (middle) and the roughness of the topography (right). All three views are centered on the relatively young impact crater Tycho, with the Orientale basin on the left side. The slope magnitude indicates the steepness of terrain, while roughness indicates the presence of large blocks, both of which are important for surface operations.

WASHINGTON —
NASA has declared full mission success for the Lunar Reconnaissance Orbiter (LRO). LRO changed our view of the entire moon and brought it into sharper focus with unprecedented detail.

NASA’s Exploration Systems Mission Directorate (ESMD) operated the LRO spacecraft and its instruments during the one-year mission phase. Now that the final data from the instruments have been added to the agency’s Planetary Data System, the mission has completed the full success requirements. The data system, which is publicly available, archives data from past and present planetary missions as well as astronomical observations and laboratory data.
