New Study Shows the Earth and Moon are not so Similar After All

According to the most widely-accepted theory, the Moon formed roughly 4.5 billion years ago when a Mars-sized object named Theia collided with Earth (aka. the Giant Impact Hypothesis). This impact threw up considerable amounts of debris which gradually coalesced to form Earth’s only natural satellite. One of the most compelling proofs for this theory is the fact that the Earth and the Moon are remarkably similar in terms of composition.

However, previous studies involving computer simulations have shown that if the Moon were created by a giant impact, it should have retained more material from the impactor itself. But according to a new study conducted by a team from the University of New Mexico, it is possible that the Earth and the Moon are not as similar as previously thought.

India’s Chandrayaan 2 is Creating the Highest Resolution Map We Have of the Moon

The Chandrayaan-2 lander, Vikram, attempted a landing September 7th (Friday the 6th in the United States), on a small patch of lunar highland smooth plains between Simpelius N and Manzinus C craters. Unfortunately the landing was not successful and location of the spacecraft has not been announced. The scene above was captured from an LROC Quickmap fly-around of the site, image width is about 150 kilometers across the center [NASA/GSFC/Arizona State University].

India’s space organization, ISRO, launched Chandrayaan 2 to the Moon last year in July. While its lander Vikram crashed on the lunar surface on September 7, the Chandrayaan 2 orbiter continues to orbit the Moon.

Has humanity been doing it all wrong? We’re busy staring off into space with our futuristic, ultra-powerful telescopes, mesmerized by ethereal nebulae and other wondrous objects, and trying to tease out the Universe’s well-kept secrets. Turns out, humble, ancient clams have something to tell us, too.

Beyond Robotic Arms. Canada Funds Technology for Space Exploration

The Canadian Space Agency (CSA) has a long-standing tradition of innovation and technological development in space. Who can forget the Shuttle Remote Manipulator System (SRMS), more familiarly known as the “Canadarm“, which was essential to the Space Shuttle program? How about its successor, the Canadarm2, which is a crucial part of the International Space Station and even helped assemble it?

Looking to the future, the CSA intends to play a similar role in humanity’s return to the Moon – which includes the creation of the Lunar Gateway and Project Artemis. To this end, the CSA recently awarded a series of contracts with private businesses and one university to foster the development of technologies that would assist with national and international efforts to explore the Moon.

Meet VIPER, NASA’s new lunar rover, equipped with a drill to probe the Moon’s surface and look for water ice. VIPER, or Volatiles Investigating Polar Exploration Rover, will carry a one-meter drill and will use it to map out water resources at the Moon’s south pole. It’s scheduled to be on the lunar surface by December 2023, one year later than it’s initial date.

With the excitement and interest in the newly discovered ‘mini-moon’ found orbiting Earth, astronomers quickly set their sights on trying to get more details, to determine what this object actually is.

Using the Gemini Observatory in Hawaii, a group of astronomers captured a clearer view of this so-called Temporarily Captured Object (TCO), named 2020 CD3. The image, above, was obtained on February 24, 2020. It shows a tiny pinpoint of light against trailing stars.

Astronomers are increasingly interested in Near-Earth Objects, or NEOs. There are ongoing efforts to find them all and catalog them all, and to find out which ones might pose a collision threat. Now some astronomers with the NASA-funded Catalina Sky Survey have found a new, tiny, temporary moon for Earth.

ESA is Going to Test Two Rovers Working Together to Explore the Moon

The ESA has spent the past few years working towards the creation of an international lunar base, something that will serve as a spiritual successor to the International Space Station (ISS). To accomplish this, they have enlisted the help of other space agencies and contractors to develop concepts for space habitats and construction methods as well as ways to provide robotic and logistical support.

Recently, the ESA’s Technology Development Element (TDE) signed on with the French technology developer COMEX to create the TRAILER robotic system. This two-year project will test a new mission architecture where two rovers work in tandem (and with the help of astronauts) for the sake of exploring the lunar surface and building a permanent outpost on the Moon.

China greeted the New Year with some impressive lunar milestones. For starters, last Friday (Jan. 3rd) was the first anniversary of the Chang’e-4 mission becoming the first robotic mission to make a landing on the far side of the Moon. A day prior, the Yutu-2 rover also celebrated the end of its 13th lunar day of science operations and the fact that it was the first rover to travel a record 357.695 meters (1,173.5 ft) on the far side of the Moon.
