Could Permanent Magnets Protect Astronauts from Solar Storms?
Shielding astronauts from the killer radiation they face is a central challenge facing any designer of a deep-space crewed mission. Even relatively low levels of exposure for long periods of time can lead to everything from central nervous system damage to cancer. But current solutions, such as passive water shells or active superconducting magnets, have their own limitations. To get around those, a new paper, available in pre-print on arXiv by Valerio Parisi and a team of researchers from Italy and Germany, looks at the feasibility of using a permanent magnet (and its associated permanent magnetic field) to potentially block some of that deadly radiation without the costs of competing technologies.

NASA Is Calling on Industry to Build Its Lunar Infrastructure
NASA is serious about going back to the Moon. Ongoing missions like the recently completed Artemis II trip around the Moon are just one such sign. But perhaps more importantly, NASA is recognizing how much additional work will have to go into funding technology development if we hope to stay on the lunar surface permanently. To reflect that understanding, the agency recently released a request for public feedback on what it calls the Lunar Enabling Infrastructure Accelerator - which might have been named after a Star Wars fan, since its acronym is LEIA.

A New Net-Membrane Could Clean Up Some Tricky Space Debris
We’ve reported on all kinds of wacky ideas for capturing and deorbiting space debris safely. From electric tethers to lasers, engineers and scientists have been trying everything they can think of to deal with the ever-increasing orbital debris problem. But one simple design keeps popping up over and over again - a net. A new paper from researchers at the Chinese Academy of Sciences and the University of Electronic Science and Technology of China details one of the most advanced net concepts yet - but whether we can actually build one remains to be seen.

In Anticipation of New Horizons Entering Interstellar Space, Researchers are Developing a Solar Wind Forecasting Method
Southwest Research Institute (SwRI) scientists are using a solar wind forecasting method combined with analytic and numerical heliosphere models to find out where the first plasma boundary of the outer heliosphere lies as NASA’s New Horizons spacecraft hurtles toward this mysterious region of space.

The Quiet Conversation Between Muscle and Gravity, and What Happens When It Stops
Every muscle in the human body is, in a sense, in constant conversation with gravity, sensing load and responding accordingly to stay strong. Remove that conversation, as happens to astronauts in orbit, and the consequences unfold at a molecular level long before they become visible. New NASA-supported research is tracing exactly how that breakdown happens, using a purpose-built model that mimics weightlessness here on Earth. The surprising twist is where else this knowledge might apply

Weaving the Future of Space Suits
The famous opening scene of the Martian has Mark Watney stabbed in the torso with a communications antenna. While this accident sets up the plot for what is widely regarded as a modern classic of sci-fi storytelling, what if he was wearing a space suit that would have stopped the impact altogether? That’s the idea behind a recent NASA Small Business Innovation Research (SBIR) Phase I program run by researchers from Materials Research & Design, Fiber Materials, Inc, and NASA’s Johnson Space Center. Their work, which was recently presented at the National Space & Missile Materials Symposium, showcased a type of advanced 3D-reinforced fabric that could have saved Watney and his compatriots a whole lot of trouble.

How NASA Taught Four Astronauts to Read the Moon
When Artemis II swept around the far side of the Moon this April, carrying the first humans beyond Earth orbit in more than fifty years, NASA had prepared its four astronauts for something more than flying the spacecraft. It had trained them to see. Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen spent two years learning to read the Moon like field geologists, hunting through impact rocks in Labrador and volcanic ash in Iceland, so that when they finally gazed down on the terrain, they could describe its colours, shadows and history with a scientist's judgement. It’s a quiet revolution in what we send astronauts to the Moon to do, and a glimpse of how the next explorers will work when they finally land.

Using Plants, Astronauts Could Create Their Own Medicine
A new pharmaceutical production method could allow astronauts on long space missions to "grow" fresh medicines on demand using plants. The work could also bring low-cost pharmaceutical production to resource-limited areas on Earth.

Future Martian Colonists Will Need a New Relativistic Clock
We think of atomic clocks as the definitive timekeepers. They are famous for being accurate down to the picosecond. Unfortunately, they are still subject to general relativity, so if you put them on a different planet, they will track time slightly faster or slower than on Earth, depending on the planet’s gravity. In Mars’ case, an atomic clock on its surface is sitting in a slightly shallower gravity well, meaning that time moves slightly faster there. Therefore, as we begin to expand our technological footprint on the Red Planet, we will need a way to standardize how time is measured there. Dr. Slava Turyshev, a researcher at NASA’s Jet Propulsion Laboratory, proposes just such a framework in a new paper available in pre-print on arXiv.

Meet REMORA: The Autonomous Space Fleet Built to Tag and Track Asteroids
To truly understand what an asteroid is made up of, we need to send a probe to it. Remote sensing from ground-based telescopes, or even orbiting observatories, and only do so much. A new white paper submitted to the UK Space Agency’s 2035 Space Frontiers programme, pitches just such a mission architecture. Called the REndezvous Mission for Orbital Reconstruction of Asteroids (REMORA), the plan calls for a swarm of autonomous CubeSats to tag, track, and characterize multiple near-Earth asteroids.

Building in Space With Laser "Origami"
University of Florida researchers are exploring how lasers could help astronauts build structures on the moon using materials already available there, including lunar soil transformed into glass. The work, led by Victoria M. Miller, Ph.D., an associate professor in the Herbert Wertheim College of Engineering and researcher with the UF Astraeus Space Institute, recently completed a research phase focused on laser forming, a manufacturing process that bends materials without physical contact.

The SETI Institute Releases Technosignature Report on 3I/ATLAS
Scientists at the SETI Institute searched for technological signals from 3I/ATLAS, the third interstellar object observed in our Solar System. Using the Allen Telescope Array (ATA) at the Hat Creek Radio Observatory in Northern California, the team scanned a wide range of radio frequencies for signs of extraterrestrial technology and found none, as expected based on other astronomical observations showing that the object exhibits natural comet-like composition and behavior. “Eventually, our own Voyager spacecraft will be extraterrestrial artifacts in other stellar systems,” said Dr. Sofia Sheikh, lead author on the paper. “Given that, it is important that we understand the natural distribution of interstellar objects so that we will be able to identify any anomalies that could one day be signs of an artificial interstellar object.” The team observed 3I/ATLAS for more than seven hours with the ATA, covering 1 to 9 gigahertz. This broad range allows scientists to search for narrowband radio signals, which are not produced by in nature and would be evidence of technology.

A “Green” Dual-Mode Engine is About to Give CubeSats the Best of Both Worlds
Rocket scientists have always faced a trade-off in propulsion technologies. Chemical rockets can provide lots of oomph, but burn through fuel so quickly they can only do so for a few minutes. Electric propulsion, on the other hand, can run for days, but the pushing power they provide is miniscule compared to their chemical cousins. A new paper in the Journal of Propulsion and Power from researchers at MIT describes a system that might be the best of both worlds - a propulsion system that includes an electrospray thruster that uses a chemical rocket propellant, and can seamlessly switch to a chemical rocket when needed.
