SpaceIL Spacecraft Snaps Stunning Images of the Far Side of the Moon

SpaceIL Spacecraft Snaps Stunning Images of the Far Side of the Moon Beresheet just became the first Israeli and privately-financed spacecraft to enter the moon’s orbit. Israeli nonprofit SpaceIL successfully inserted its spacecraft, Beresheet, into the moon’s orbit yesterday-and they have the photos to prove it. Late night the spacecraft’s moon-capture maneuver caught these stunning photos of the far side of the moon. One photo is a close up of the surface, taken at a height of 470 km. The other photo captures part of the far side of the moon with Earth in the background.

There are also very few of the "maria"

China's Chang'e-4 mission, the first to land on the far side of the moon, is shedding light on one of the moon's biggest mysteries, according to a new study.

For all of the jokes suggesting the moon is made of cheese, researchers have actually been trying to understand the composition of the lunar mantle, which exists between the crust and the core.

Impact craters are how researchers can learn more about the moon's evolution and how it formed. When asteroids and other objects collide with the moon, the crust is cracked and pieces of the mantle reach the surface. So the Yutu-2 rover went looking for some of those pieces. The study detailing its findings was published Wednesday in the journal Nature.

A Chinese spacecraft has become the first to land on the far side of the moon in a historic moment for human space exploration. The successful touch down was hailed as a major technical feat and is seen as a important step towards China ’s wider ambitions in space. The robotic probe Chang’e 4 landed in

During the 1970s, some astronomers suggested that a magma ocean covered the moon's surface early in its history. Magma is the molten material that forms rocks. As it cooled, minerals floated to the top, and heavier elements sank. The top formed a basalt crust over a mantle of minerals. They believed that some of those minerals could be olivine and pyroxene, which are found in asteroids and Earth's upper mantle.

"Understanding the composition of the lunar mantel is critical for testing whether a magma ocean ever existed, as postulated," said Li Chunlai, study author and professor of the National Astronomical Observatories of Chinese Academy of Sciences, said in a statement. "It also helps advance our understanding of the thermal and magmatic evolution of the moon."

Israel moon landing: Spacecraft mission ends in crash

Israel moon landing: Spacecraft mission ends in crash Israel's Beresheet, the first privately-funded mission to the moon, has crashed. require(["medianetNativeAdOnArticle"], function (medianetNativeAdOnArticle) { medianetNativeAdOnArticle.getMedianetNativeAds(true); }); The spacecraft aimed to perform a soft landing on the moon and would have made Israel the fourth country to do so -- and by far the smallest. Only the United States, the former Soviet Union and China have done it before.

Chang’e 4 will test soil composition, try to grow plants, and listen for traces of Big Bang.

Chinese space agency has provided another peek into how its Chang’e 4 robotic probe is doing on the Moon after it became the first ever man-made craft to land of the unexplored far side of the Earth’s satellite. In the footage, released on Chinese microblog Weibo

Chang'e-4 landed in the Von Karman crater on January 3. Then, it deployed Yutu-2. The rover's purpose was to explore the South Pole-Aitken basin, the oldest and largest crater on the far side of the moon, which is 1,553 miles across.

Data samples collected by the rover on the basin floor indicated traces of olivine. Samples from deeper impacts within the basin revealed more olivine. Because basalt contains both, researchers theorized that the mantle could contain olivine and pyroxene equally, rather than being dominated by one.

The rover will need to explore more of its landing site to understand the mantle's composition, but the first mission to the far side of the moon is already gathering crucial data.

Next, Yutu-2 will sample more material from the floor of the crater to determine its origin, and researchers are looking at the possibility of returning samples to Earth.

India sets July launch date for moon landing attempt.
Officials in India have announced that their mission to land on the surface of the moon now is scheduled for mid-July, according to news reports. The Chandrayaan-2 mission consists of an orbiter, lander and rover that will explore the moon's south pole. It is now set to launch from Sriharikota -- a barrier island off the Bay of Bengal --between July 9 and July 16.
