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.

The Robert C. Byrd Green Bank Telescope (GBT), part of the Green Bank Observatory in West Virginia, is the world’s premiere single-dish radio telescope. Between its 100-meter dish (328-foot), unblocked aperture, and excellent surface accuracy, the GBT provides unprecedented sensitivity in the millimeter to meter wavelengths – very high to extremely high frequency (VHF to EHF). Since 2017, it also became one of the main instruments used by Breakthrough Listen and other institutes engaged in the Search for Extraterrestrial Intelligence (SETI).

On September 26th, NASA’s Double Asteroid Redirection Test (DART) spacecraft collided with Dimorphos, the small moonlet that orbits the larger Near-Earth Asteroid (NEA) Didymos. The purpose was to test a planetary defense technique known as the kinetic impact method, where a spacecraft intentionally collides with a Potentially Hazardous Asteroid (PHAs) to alter its course. Based on a post-collision analysis, NASA determined that DART’s impact altered Dimorphos’ orbital period by 33 minutes and caused tons of rock to be ejected from its surface.

Jupiter is the most-visited planet in the Solar System, thanks largely to NASA. It all started with Pioneer 10 and 11, followed by Voyager 1 and 2. Those were all flyby missions, and it wasn’t until 1996 that the Galileo spacecraft became the first to orbit the gas giant and even send a probe into its atmosphere. Then in 2016, the Juno spacecraft entered orbit around Jupiter and is still there today.

Since it launched on December 25th, 2021 (quite the Christmas present!), the James Webb Space Telescope (JWST) has taken the sharpest and most detailed images of the Universe, surpassing even its predecessor, the venerable Hubble Space Telescope! But what is especially exciting are the kinds of observations we can look forward to, where the JWST will use its advanced capabilities to address some of the most pressing cosmological mysteries. For instance, there’s the problem presented by high-redshift supermassive black holes (SMBHs) or brightly-shining quasars that existed during the first billion years of the Universe.

Here’s a thorny problem: What if life doesn’t always appear on planets that can support it? What if we find more and more exoplanets and determine that some of them are habitable? What if we also determine that life hasn’t appeared on them yet?

As of December 19th, 2022, 5,227 extrasolar planets have been confirmed in 3,908 systems, with over 9,000 more awaiting confirmation. While most of these planets are Jupiter- or Neptune-sized gas giants or rocky planets many times the size of Earth (Super-Earths), a statistically significant number have been planets where water makes up a significant part of their mass fraction – aka. “water worlds.” These planets are unlike anything we’ve seen in the Solar System and raise several questions about planet formation in our galaxy.
