GREENBELT, Md. — Dozens of times over the last decade NASA scientists have launched laser beams at a reflector the size of a paperback novel about 240,000 miles (385,000 kilometers) away from Earth. They announced today, in collaboration with their French colleagues, that they received signal back for the first time, an encouraging result that could enhance laser experiments used to study the physics of the universe.
HOUSTON (NASA PR) — As part of the Artemis lunar exploration program, NASA plans to return astronauts to the Moon and use that experience to inform future human exploration of Mars. To safely and comfortably explore for days at a time on the surface of these celestial bodies, astronauts need suitable equipment and places to live. Almost 20 years of human habitation aboard the International Space Station and a growing body of research conducted there are contributing important insights into how to meet these needs for future lunar explorers.
ISRO Chairman K Sivan is disputing that idea that NASA was the first to positively identified the wreckage of India’s Vikram lunar lander after its location was discovered by Indian amateur astronomer Shanmuga Subramanium.
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.
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).
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.
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.
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.
The lighting will be favorable when LRO passes over the site in October and once again attempts to locate and image the lander.
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.
GREENBELT, Md. (NASA PR) — 5:32 p.m. Eastern Time on June 18, 2019, marks 10 years since the launch of the Lunar Reconnaissance Orbiter (LRO). Its contributions to the fields of lunar science and exploration are unmatched: it has provided the largest volume of data ever collected by a planetary science mission.
GREENBELT, Md. (NASA PR) — The photo above shows the landing site of the Israeli Beresheet spacecraft on a region of the Moon called Sea of Serenity, or Mare Serenitatis in Latin. On April 11, 2019, SpaceIL, a non-profit organization, attempted to land its spacecraft in this ancient volcanic field on the nearside of the Moon. After a smooth initial descent, Beresheet made a hard landing on the surface.
GREENBELT, Md. (NASA PR) — Scientists, using an instrument aboard NASA’s Lunar Reconnaissance Orbiter (LRO), have observed water molecules moving around the dayside of the Moon.
A paper published in Geophysical Research Letters describes how Lyman Alpha Mapping Project (LAMP) measurements of the sparse layer of molecules temporarily stuck to the surface helped characterize lunar hydration changes over the course of a day.

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.
Video Caption: In December of 1968, the crew of Apollo 8 became the first people to leave our home planet and travel to another body in space. But as crew members Frank Borman, James Lovell, and William Anders all later recalled, the most important thing they discovered was Earth.
Using photo mosaics and elevation data from Lunar Reconnaissance Orbiter (LRO), this video commemorates Apollo 8’s historic flight by recreating the moment when the crew first saw and photographed the Earth rising from behind the Moon. Narrator Andrew Chaikin, author of “A Man on the Moon,” sets the scene for a three-minute visualization of the view from both inside and outside the spacecraft accompanied by the onboard audio of the astronauts.
Video Caption: Take a virtual tour of the Moon in all-new 4K resolution, thanks to data provided by NASA’s Lunar Reconnaissance Orbiter spacecraft. As the visualization moves around the near side, far side, north and south poles, we highlight interesting features, sites, and information gathered on the lunar terrain.

WASHINGTON, DC (NASA PR) — NASA is focused on an ambitious plan to advance the nation’s space program by increasing science activities near and on the Moon and ultimately returning humans to the surface.
As part of the President’s fiscal year 2019 budget proposal, NASA is planning a new Moon-focused exploration campaign that starts with a series of progressive commercial robotic missions.
