Astronauts Deploy the First Wooden Satellite into Orbit

Wood has been a mainstay of human machines and construction for millennia. Its physical properties offer capabilities that are unmatched by almost any synthetic replacements. However, it has only very rarely been used in space. That might change based on the results of a new test run by Japan’s Space Agency (JAXA). LignoSat, one of the world’s first wooden satellites, was deployed from the ISS in December.

A New Industrial Megaproject Threatens the View of the World’s Best Observatories

The dark skies above ESO’s Paranal Observatory, home to ESO’s Very Large Telescope (VLT), yield breathtaking views so clear and so full of stars that you could almost touch them. Standing atop a platform at VLT, ESO Photo Ambassador Petr Horálek reaches towards a standout object in the sky. You may assume this bright body, like many others in the sky, to be a star, but it is in fact a planet in our Solar System: the gas giant Jupiter. Closer to Earth, the four Unit Telescopes (UTs) that comprise the VLT can be seen in the background. Each UT features an 8.2-metre mirror and they operate synergistically to produce some of the sharpest views of the Universe. Accompanying the four UTs are four smaller, moveable Auxiliary Telescopes (ATs) which have 1.8-metre mirrors. The Chilean Atacama desert once again proves its value as the ideal location for ESO’s VLT. The remoteness of the observatory means that there is very little to no light pollution, which is vital for astronomy and also yields such breathtaking views.

Astronomers have been battling threats to their clear skies on all fronts lately. One of the most notable battles, which we have reported on repeatedly, is the one against Starlink and other mega-constellations of satellites, which, while they offer high-speed internet in the most far-flung places, also disrupt observations by sensitive telescopes due to their reflectivity and fast movement speed. They also pose a global problem, whereas a more down-to-earth issue is cropping up at one very special observatory. A vast industrial plant threatens the European Southern Observatory’s Paranal telescope planned only a few kilometers from the site.

SLS Could Launch A Titan Balloon Mission

Few places in the solar system are better suited to a balloon than Titan. The combination of low gravity and high atmospheric density makes Saturn’s largest moon ideal for a lighter than “air” vehicle, and the idea to put one there has been around for at least two decades. So why haven’t we yet? The simple answer is the size of the necessary balloon is too large for the existing launch platforms. But a team from Boeing, the prime contractor on the Space Launch System (SLS), believes their new launch platform will be capable of getting a large balloon into orbit, along with its necessary scientific payload – and start unlocking the mysteries of this intriguing moon.

How to Deploy and Talk To LEAVES on Venus

We reported before about a NIAC-funded project known as the Lofted Environment and Atmospheric Venues Sensors (LEAVES) mission to study Venus’ atmosphere. While the technology behind the idea is still under development, it has already inspired a team of Worcester Polytechnic Institute (WPI) undergraduates to develop a supporting satellite mission to launch and communicate with the leaves. Their paper, part of their B.S. Thesis, details how to use these new sensors and the challenges ahead.

A CubeSat Mission Will Detect X-rays from GRBs and Black-Hole Mergers

The long-awaited detection of gravitational waves has opened up a whole new world of astronomy. One of the key efforts is now to tie signals across multiple domains – for example, a gravitational wave and the associated electromagnetic radiation created by that same event, such as a black hole merger or a gamma-ray burst. We’ll need new equipment to detect such “multimodal” signals, especially electromagnetic ones. One such project is the Black Hole Coded Aperture Telescope (BlackCAT), which will be launched early this year by a team led by researchers at Penn State.

Pushing A Probe To Alpha Centauri Using A Relativistic Electron Beam

Getting a spacecraft to another star is a monumental challenge. However, that doesn’t stop people from working on it. The most visible groups currently doing so are Breakthrough Starshot and the Tau Zero Foundation, both of whom focus on a very particular type of propulsion-beamed power. A paper from the Chairman of Tau Zero’s board, Jeffrey Greason, and Gerrit Bruhaug, a physicist at Los Alamos National Laboratory who specializes in laser physics, takes a look at the physics of one such beaming technology – a relativistic electron beam – how it might be used to push a spacecraft to another star.

Student Team Designs 2U CubeSat with Big Ambitions

CubeSats can be used in many different scenarios, and one of their most important uses is providing an easy path to understanding how to design, plan, and launch a mission. That was the idea behind AlbaSat, a 2U CubeSat currently under development by a team at the University of Padova with an impressive four different functional sensors packed into its tiny frame.

Using an Oil Industry Framework to Map Space Resources

Cracking the chicken-and-egg problem of utilizing resources in space has been a difficult challenge for over half a century. Getting enough infrastructure built up is necessary to collect those resources effectively, but doing so is too expensive without using the resources themselves. Trying to crack that problem has been the focus of a variety of space exploration enthusiasts, and one of them, Don Barker, is currently the Gateway HALO Utilization & Visiting Vehicle Integration Lead at ARES Corporation. He published a paper in 2020 that detailed how the space exploration industry could use a modified version of a framework from the oil and gas industry, which he calls the Planetary Resource Management System (PRMS), to calculate where we should focus on settlement efforts.

A Long-Term Lunar Infrastructure Hub Named After the Object That Created the Moon

Getting back to the Moon is the primary goal of NASA’s Artemis program, but what do we do once we get there? That is the challenge tackled by a group of students at the University of Illinois Urbana-Champaign, who wrote a proposal for a lunar infrastructure module they call the Trans-lunar Hub for Exploration, ISRU, and Advancement – or THEIA, after the proposed object that crashed into the Earth that created the Moon as we know it today. Their submission was part of the NASA Revolutionary Aerospace Systems Concepts – Academic Linkage project, where teams from various academic institutions submitted papers focusing on the theme of Sustained Lunar Evolution for 2024.

A New Mission Watches Meteoroids Hit the Far Side of the Moon

Sometimes, it’s hard to remember that Earth is constantly being bombarded by literally tons of space debris daily. The larger bits form what we know as shooting stars, and most burn up in the atmosphere. Still, throughout our planet’s history, giant versions have caused devastation unlike anything else seen on this planet. Tracking these types of objects is typically done from the Earth, but a new mission set out by researchers in Italy has a novel idea – why not try to learn more about potential impactors by watching them hit the far side of the Moon?
