You had to be in the right part of North America to get a great view of the recent solar eclipse. But a particular telescope may have had the most unique view of all. Even though that telescope is in Hawaii and only experienced a partial eclipse, its images are interesting.

Exploration of the Moon or other dusty environments comes with challenges. The lunar surface is covered in material known as regolith and its a jaggy, glassy material. It can cause wear and tear on equipment and can pose a health risk to astronauts too. Astronauts travelling to Mars would experience dust saucing to everything, including solar panels leading to decrease in power. To combat the problems created by dust, NASA is working on an innovative electrodynamic dust shield to remove dust and protect surfaces from solar panels to space suits.

How can future lunar exploration communicate from the far side of the Moon despite never being inline with the Earth? This is what a recent study submitted to IEEE Transactions on Aerospace and Electronic Systems hopes to address as a pair of researchers from the Polytechnique Montréal investigated the potential for a wireless power transmission method (WPT) comprised of anywhere from one to three satellites located at Earth-Moon Lagrange Point 2 (EMLP-2) and a solar-powered receiver on the far side of the Moon. This study holds the potential to help scientists and future lunar astronauts maintain constant communication between the Earth and Moon since the lunar far side of the Moon is always facing away from Earth from the Moon’s rotation being almost entirely synced with its orbit around the Earth.

Pink Floyd was wrong, there is no dark side to the Moon. There is however, a far side. The tidal effects between the Earth and Moon have caused this captured or synchronous rotation. The two sides display very different geographical features; the near side with mare and ancient volcanic flows while the far side displaying craters within craters. New research suggests the Moon has turned itself inside out with heavy elements like titanium returning to the surface. It’s now thought that a giant impact on the far side pushed titanium to the surface, creating a thinner more active near side.

In 2009, NASA launched the Lunar Reconnaissance Orbiter (LRO.) Its ongoing mission is to map the lunar surface in detail, locating potential landing sites, resources, and interesting features like lava tubes. The mission is an ongoing success, another showcase of NASA’s skill. It’s mapped about 98.2% of the lunar surface, excluding the deeply shadowed regions in the polar areas.
But recently, the LRO team’s skill was on display for another reason: it captured images of another satellite speeding over the lunar surface.

On Monday, April 8th, people across North America witnessed a rare celestial event known as a total solar eclipse. This phenomenon occurs when the Moon passes between the Sun and Earth and blocks the face of the Sun for a short period. The eclipse plunged the sky into darkness for people living in the Canadian Maritimes, the American Eastern Seaboard, parts of the Midwest, and northern Mexico. Fortunately for all, geostationary satellites orbiting Earth captured images of the Moon’s shadow as it moved across North America.

It has often been likened to talcum powder. The ultra fine lunar surface material known as the regolith is crushed volcanic rock. For visitors to the surface of the Moon it can be a health hazard, causing wear and tear on astronauts and their equipment, but it has potential. The fine material may be suitable for building roads, landing pads and shelters. Researchers are now working to analyse its suitability for a number of different applications.

Some of the biggest names in aerospace — and the automotive industry — will play roles in putting NASA astronauts in the driver’s seat for roving around on the moon.
The space agency today selected three teams to develop the capabilities for a lunar terrain vehicle, or LTV, which astronauts could use during Artemis missions to the moon starting with Artemis 5. That mission is currently scheduled for 2029, three years after the projected date for Artemis’ first crewed lunar landing.
The teams’ leading companies may not yet be household names outside the space community: Intuitive Machines, Lunar Outpost and Venturi Astrolab. But each of those ventures has more established companies as their teammates.

Sometimes, all you need for a new discovery is some creative math. That was the case for a new paper by Edward Williams and Laurent Montési of the University of Maryland’s Department of Geology. They released a brief paper at the Lunar and Planetary Science Conference last month that describes a mathematical way to estimate the size of a lava tube using only remote sensing techniques.

Intuitive Machines recently had a major breakthrough, successfully becoming the first non-governmental entity to land on the Moon in February. At least the landing was partially successful – the company’s Odysseus lander ended up on its side, though its instruments and communication links remained at least partially functional. That mission, dubbed IM-1, was the first in a series of ambitious missions the company has planned. And they recently released a paper detailing features of a unique hopping robot that will hitch a ride on its next Moon mission.
