There May be Thick Ice Deposits on the Moon and Mercury

In addition to being the only solvent that is capable of supporting life, water is essential to life as we know it here on Earth. Because of this, finding deposits of water – whether in liquid form or as ice – on other planets is always exciting. Even where is not seen as a potential indication of life, the presence of water offers opportunities for exploration, scientific study, and even the creation of human outposts.

This has certainly been the case as far as the Moon and Mercury are concerned, where water ice was discovered in the permanently-shadowed cratered regions around the poles. But according to a new analysis of the data from the Lunar Reconnaissance Orbiter and the MESSENGER spacecraft, the Moon and Mercury may have significantly more water ice than previously thought.

Rock Almost Rolled Into This Crater on the Moon… Almost

The history of the Moon is a tale told by geology, apparent in its rocks, craters, and other surface features. For centuries, astronomers have studied the Moon from afar and for the past few decades, it has been visited by countless robotic missions. Between 1969 and 1972, a total of twelve astronauts walked on its surface, conducted lunar science, and brought samples of lunar rock back to Earth for study.

These efforts have taught us a lot about the things that have shaped the lunar surface, be they one-off events like the massive impact that formed the Shakleton crater to things that happened regularly throughout its 4.51 billion-year history. For instance, scientists recently discovered something unusual about the Antoniadi crater: a large boulder was perched on the rim of a smaller crater within after rolling about 1000 meters (1093 yards) downhill.

The Moon is Older Than Scientists Thought

The most comprehensive and widely-held theory of how the Moon formed is called the ‘giant impact hypothesis.’ That hypothesis shows that about 150 million years after the Solar System formed, a roughly Mars-sized planet named Theia collided with Earth. Though the timeline is hotly-debated in the scientific community, we know that this collision melted Theia and some of Earth, and that molten rock orbited around Earth until it coalesced into the Moon.

But now a new study, though not contradicting the giant impact hypothesis, is suggesting a different timeline, and an older Moon.

Why Is The Moon’s South Pole So Important? It’s All About Water

As NASA prepares to return to the Moon by 2024 as part of its Artemis program, the agency is focusing its efforts on exploring the Moon’s polar regions. These are areas of the Moon which seem to have a lot of water mixed in with the regolith.

JAXA, the Japan Aerospace Exploration Agency, is teaming up with the nation’s largest company to build a lunar rover. Toyota, the second largest automobile company in the world (only Volkswagen makes more cars) has signed a development deal with JAXA that will last three years. The goal? To design, build, test and evaluate prototypes for a pressurized, crewed lunar vehicle that runs on fuel-cells.

ISRO (Indian Space Research Organization) has successfully launched their Chandrayaan-2 mission to the Moon. The mission, which includes an orbiter, a lander, and a rover, was launched into space on a GSLV Mk III rocket on July 22nd, after a week-long delay. On September 7th it will perform a soft-landing on the Moon.

Two NASA Heads Demoted, Possibly as Part of a Shake-Up to Get Back to the Moon.

On March 26th, 2019, during the fifth meeting of the reestablished National Space Council, Vice President Mike Pence challenged NASA to land astronauts on the Moon within the next five years. This represented an order to expedite Space Policy Directive-1 signed by President Trump on December 11th, 2017, which directed NASA to take all the necessary steps to send astronauts back to the Moon.

This announcement suggested that some shake-up might be taking place within the agency to make things happen. However, it appears that this now involves the demotion of two longtime NASA heads who have dedicated much of their lives to the advancement of human space exploration. Whether or not this decision came from the White House is unclear, but it is in keeping with the direction recently issued by VP Pence.

Is NASA Sacrificing Sending Astronauts to Mars in Order to Get to the Moon Sooner?

On December 11th, 2017, President Trump issued Space Policy Directive-1, a change in national space policy which tasked NASA with the creation of an innovative and sustainable program of exploration that would send astronauts back to the Moon. This was followed on March 26th, 2019, with President Trump directing NASA to land the first astronauts since the Apollo era on the lunar South Pole by 2024.

Named Project Artemis, after twin sister of Apollo and goddess of the Moon in Greek mythology, this project has expedited efforts to get NASA back to the Moon. However, with so much focus dedicated to getting back to the Moon, there are concerns that other projects being neglected – like the development of the Lunar Orbital Platform-Gateway, a central part of creating a sustained human presence on the Moon and going on to Mars.

Apollo 10’s “Snoopy” Lunar Lander May Have Been Found in Space

Apollo 11 was the first mission to land people on the lunar surface. But Apollo relied on a lot of predecessor missions to lay the groundwork for the successful mission to the Moon. One of them was Apollo 10, the fourth crewed mission in the Apollo program.

Apollo 10 was an almost complete mission that including everything that Apollo 11 had, except for an actual landing on the Moon. It was a dress rehearsal, and was the second Apollo mission to orbit the Moon. It even had an Apollo Lunar Module that was flown to within 15 km of the lunar surface. But that module never landed, and eventually, after it rendezvoused with the command module and the crew disembarked, it was sent into orbit around the Sun.

And up until now, nobody knew where it was.

That Explains a Lot. The Moon’s Largest Crater has a Chunk of Metal Embedded in it That’s 5 Times Bigger than the Big Island of Hawaii

One of the largest craters in the Solar System is on our Moon. It’s called the South Pole-Aitken (SPA) basin and it’s 2,500 km (1,600 mi) in diameter and 13 km (8.1 mi) deep. A new study says that the basin may contain an enormous chunk of metal that’s larger than Hawaii’s Big Island.
