Water on the Moon has been a hot topic in the research world lately. Since its first unambiguous discovery back in 2008. Since then, findings of it have ramped up, with relatively high concentration levels being discovered, especially near the polar regions, particularly in areas constantly shrouded in shadow. Chang’e 5, China’s recent sample return mission, didn’t land in one of those permanently shadowed areas. Still, it did return soil samples that were at a much higher latitude than any that had been previously collected. Now, a new study shows that those soil samples contain water and that the Sun’s solar wind directly impacted that water.

Although dark matter is a central part of the standard cosmological model, it’s not without its issues. There continue to be nagging mysteries about the stuff, not the least of which is the fact that scientists have found no direct particle evidence of it. Despite numerous searches, we have yet to detect dark matter particles. So some astronomers favor an alternative, such as Modified Newtonian Dynamics (MoND) or modified gravity model. And a new study of galactic rotation seems to support them.

When humans start living and working on the Moon in the Artemis missions, they’re going to need good navigational aids. Sure, they’ll have a GPS equivalent to help them find their way around. And, there’ll be LunaNet, the Moon’s equivalent to the Internet. But, there are places on the lunar that are pretty remote. In those cases, explorers could require more than one method for communication and navigation. That prompted NASA Goddard research engineer Alvin Yew to create an AI-driven local map service. It uses local landmarks for navigation.

NASA’s continued goal of sending humans into deep space using its Space Launch System (SLS) recently took a giant leap as the world’s largest space agency finalized the SLS Stages Production and Evolution Contract worth $3.2 billion with The Boeing Company in Huntsville, Alabama. The purpose of the contract is for Boeing to keep building SLS core and upper stages for future Artemis missions to the Moon and beyond for at least five more SLS launches.

With the help of international and commercial partners, NASA is sending astronauts back to the Moon for the first time in over fifty years. In addition to sending crewed missions to the lunar surface, the long-term objective of the Artemis Program is to create the necessary infrastructure for a program of “sustained lunar exploration and development.” But unlike the Apollo missions that sent astronauts to the equatorial region of the Moon, the Artemis Program will send astronauts to the Moon’s South Pole-Aitken Basin, culminating in the creation of a habitat (the Artemis Basecamp).

In a recent study published in The Astrophysical Journal Letters, an international team of researchers led by the University of Cologne in Germany examined how solar flares erupted by the TRAPPIST-1 star could affect the interior heating of its orbiting exoplanets. This study holds the potential to help us better understand how solar flares affect planetary evolution. The TRAPPIST-1 system is an exolanetary system located approximately 39 light-years from Earth with at least seven potentially rocky exoplanets in orbit around a star that has 12 times less mass than our own Sun. Since the parent star is much smaller than our own Sun, then the the planetary orbits within the TRAPPIST-1 system are much smaller than our own solar system, as well. So, how can this study help us better understand the potential habitability of planets in the TRAPPIST-1 system?

Traditional mining has been subject to a negative stigma for some time. People, especially in developed countries, have a relatively negative view of this necessary economic activity. Primarily that is due to its environmental impacts – greenhouse gas emissions and habitat destruction are some of the effects that give the industry its negative image. Mining in space is an entirely different proposition – any greenhouse gases emitted on the Moon or asteroids are inconsequential, and there is no habitat to speak of on these barren rocks. So what is the general public’s opinion on mining in space? A paper from a group of researchers in Australia, one of the countries most impacted by the effects of terrestrial mining, now gives us an answer.

Astronomy 2023 highlights include two fine solar eclipses, the Sun heading towards solar maximum, a series of spectacular lunar occultations and much more.

Mars might not be the first place you would think of when thinking about where wind power might be useful. It has dust storms similar in scale to anything that the Earth can muster, and they’ve been responsible for the death of lots of the technology we’ve sent to the Red planet over the years. However, the strength of those storms is only enough to lift some dust particles into the air, which eventually shrouds that technology’s solar panels. Scientists have thought that it doesn’t really have enough oomph to be useful for anything. However, a new paper calls that assumption into question and shows that wind power could be useful on Mars.

There’s an old adage in the engineering field – what gets funded gets built. So it’s sure to be a happy time over at the Planetary Society, as NEO Surveyor, the project the organization has primarily supported over the past few years, has made it through NASA’s grueling budgetary process to reach the “development” stage, with an eye for a launch of the system in 2028.

Inspiration for space exploration can come from all corners. One of the most inspiring, or terrifying, sources of inspiration for some in space exploration came from computer science expert John von Neumann, who laid out a framework for self-replicating machines in a series of lectures he gave in 1948. Ever since then, scientists and engineers have been debating the advantages, and the perils, of such a system.

Over seven years ago, the New Horizons mission made history when it became the first spacecraft to conduct a flyby of Pluto. In the leadup to this encounter, the spacecraft provided updated data and images of many objects in the inner and outer Solar System. Once beyond the orbit of Pluto and its moons, it embarked on a new mission: to make the first encounter with a Kuiper Belt Object (KBO). This historic flyby occurred about four years ago (Dec. 31st, 2015) when New Horizons zipped past Arrokoth (aka. 2014 MU69).

Studying the large-scale structure of our galaxy isn’t easy. We don’t have a clear view of the Milky Way’s shape and features like we do of other galaxies, largely because we live within it. But we do have some advantages. From within, we’re able to carry out close-up surveys of the Milky Way’s stellar population and its chemical compositions. That gives researchers the tools they need to compare our own galaxy to the many millions of others in the Universe.

For decades, astrophysicists have theorized that the majority of matter in our Universe is made up of a mysterious invisible mass known as “Dark Matter” (DM). While scientists have not yet found any direct evidence of this invisible mass or confirmed what it looks like, there are several possible ways we could search for it soon. One theory is that Dark Matter particles could collide and annihilate each other to produce cosmic rays that proliferate throughout our galaxy – similar to how cosmic ray collisions with the interstellar medium (ISM) do.

When a spiral galaxy presents itself just right, observations reveal more detail. That’s the case with NGC 7469, a spiral galaxy about 220 million light-years away. It’s face-on towards us, and the James Webb Space Telescope captured its revealing scientific portrait.

In a recent study published in The Planetary Science Journal, a pair of researchers led by The Carl Sagan Center at the SETI Institute in California investigated the potential origin for the thick regolith deposits on Uranus’ moon, Miranda. The purpose of this study was to determine Miranda’s internal structure, most notably its interior heat, which could help determine if Miranda harbors—or ever harbored—an internal ocean.

Black holes are confounding objects that stretch physics to its limits. The most massive ones lurk in the centers of large galaxies like ours. They dominate the galactic center, and when a star gets too close, the black hole’s powerful gravitational force tears the star apart as they feed on it. Not even the most massive stars can resist.

In the not-too-distant future, a planetary scientist will open up a tube of rocks that came from Mars. Thanks to the Perseverance rover, there are at least 17 of these rock and regolith samples, just waiting for analysis on Earth. To get them, the rover has covered about 13 kilometers on its Mars geology field trip.

On November 16th, NASA launched the first mission of the Artemis Program (Artemis I), which splashed down three and a half weeks later. This uncrewed mission saw the Space Launch System (SLS) send an Orion spacecraft far beyond the orbit of the Moon, establishing a new record for distance traveled by a mission and the amount of time spent beyond Low Earth Orbit (LEO). Powering the core stage of the SLS were four Aerojet Rocketdyne RS-25s, the same engines used by the Space Shuttle – known as the Space Shuttle Main Engine (SSME).

The InSight lander might have transmitted its last picture from the surface of Mars. It looks like the lander is succumbing to Mars’ dusty conditions, as its ability to generate energy from its solar panels has been declining in recent weeks.

The James Webb Space Telescope is delivering a deluge of images and data to eager scientists and other hungry-minded people. So far, the telescope has shown us the iconic Pillars of Creation like we’ve never seen them before, the details of very young stars as they grow inside their dense cloaks of gas, and a Deep Field that’s taken over from the Hubble’s ground-breaking Deep Field and Ultra Deep Field images. And it’s only getting started.
