Real-life ‘stillsuit’: Dune-inspired upgrade for spacesuits allow astronauts to recycle urine into water

Existing waste management systems for spacesuits are uncomfortable, unhygienic, and don’t recycle valuable water in urine. Now, researchers from Cornell University have designed a prototype for an integrated urine collection and recycling system, which can be carried on the back of next-generation spacesuits. The system is now ready for testing.

Wearable devices may prevent astronauts getting ‘lost’ in space

by Angharad Brewer Gillham, Frontiers science writer Image/Shutterstock.com Losing your sense of where you are can be fatal enough for aircraft pilots: spatial disorientation is a leading cause of fatal aircraft accidents. But losing your orientation in space itself is even more dangerous. Scientists have now developed wearable devices called vibrotactors that, combined with specialized training, improve people’s ability to fight spatial disorientation and could help astronauts correct themselves when their perceptions can no longer be relied upon. The sky is no longer the limit — but taking flight is dangerous. In leaving the Earth’s surface, we lose many of the cues we need to orient ourselves, and that spatial disorientation can be deadly. Astronauts normally need intensive training to protect against it. But scientists have now found that wearable devices which vibrate to give orientation cues may boost the efficacy of this training significantly, making spaceflight slightly safer. “Long duration spaceflight will cause many physiological and psychological stressors which will make astronauts very susceptible to spatial disorientation,” said Dr Vivekanand P. Vimal of Brandeis University in the United States, lead author of the article in Frontiers in Physiology. “When disoriented, an astronaut will no longer be able to rely […]

Sustainability in space travel can aid efforts here on Earth

by Angelo Vermeulen/Deborah Pirchner, Frontiers science writer Image: E|A|S (Evolving Asteroid Starships)/Joris Putteneers Dr Angelo Vermeulen is a space systems researcher at Delft University of Technology in the Netherlands, where he explores advanced concepts for interstellar exploration. Over the past decade, he has collaborated closely with the European Space Agency’s (ESA) MELiSSA program, developing concepts for bioregenerative life support systems for space. In such systems, a variety of microorganisms progressively break down human waste and the resulting compounds are harnessed by plants to produce oxygen and food for the crew. Beyond his scientific pursuits, Dr Vermeulen is also an accomplished artist and a co-founder of the SEADS (Space Ecologies Art and Design) collective. SEADS creates artworks that seamlessly integrate concepts and technologies from a diverse array of scientific disciplines, including biology, neuroscience, computer science, and astrophysics. He is the author of a recently published Frontiers in Astronomy and Space Sciences article in which he and his co-authors describe a new model that theoretically produces all required food and oxygen during long-duration and remote space missions, removing the necessity for resupply from Earth. In this latest entry to the Frontier Scientists series, he has caught up with us on his current […]

Why understanding human evolution on Earth will be absolutely essential for any future deep-space colonies to survive and thrive

By Lee G Irons, Norfolk Institute, and Morgan A Irons, Cornell University Photo of Lee and Morgan, Credit: Lee Irons and Morgan Irons Is human migration into space inevitable? Is it based on facts, or is it based upon a belief in human exceptionalism? These are some of the questions explored by Lee and Morgan Irons in a recent article published in Frontiers in Astronomy and Space Sciences, asking whether humans’ evolutionary connection to Earth requires us to inhabit space the same way we do here. Lee is a physicist, engineer, and the executive director of Norfolk Institute. Morgan is an astro-ecologist and PhD candidate at Cornell University, a Carl Sagan Institute Fellow, a US National Science Foundation Graduate Research Fellow, and a Norfolk Institute Fellow. In this latest guest editorial, they explain why – and why not – space settlement might be possible. How can such a feat be accomplished? Is it just a matter of leveraging the resources of a billionaire and the capital power of the economically developed Earth to ship the materials to Mars to build a city with a dome, followed by pressurizing the dome with an Earth-like atmosphere, and spreading biosolids (ie, sterilized human […]

Five articles you need to check out on the future of astronomy and astrophysics

By Deborah Pirchner, Frontiers science writer Image: Shutterstock.com From uncovering the long-standing mysteries in extra-galactic astrophysics to understanding the properties of the sun’s outer atmosphere, astronomy research aims to help us understand what surrounds us. Frontiers highlights some of the top astronomy articles we have published recently. In a field as vast as space itself, cutting-edge work may be concerned with particles so small they are invisible to the human eye. Similarly, discoveries may be about whole galaxies. Those new findings, as well as advances in the theory, experiment, and methodology enable us to gain a better understanding of outer space. These five articles published recently as part of the Frontiers research topic ‘Horizons in Astronomy and Astrophysics’ cover important topics at the forefront of astronomy. Some Notes About the Current Researches on the Physics of Relativistic Jets Relativistic jets are powerful plasma jets emitted at the speed of light by black holes of some galaxies, massive stars, and neutron stars. In a review article published in Frontiers in Astronomy and Space Sciences, Italian researchers provided an effective critical review about one of the most long-standing mysteries in extra-galactic astrophysics: the origin of these ejections from the centers of galaxies.

5 articles you need to check out on the future of materials research

By Angharad Brewer Gillham, Frontiers science writer Image: Shutterstock.com In a fast-moving field of research like materials science, it can be difficult to keep up with the latest breakthroughs. Now at Frontiers, we highlight just five of the latest research articles to shed more light on the way we build our world around us, published by top researchers in the Frontiers in Materials Research Topic ‘Horizons in Materials’. Growing green technology: from trees to tech Scientists aiming to power the appliances of the future are developing special phenolic compounds from resins instead of petrol – a first step towards organic electrodes. Since biomass is the only green, renewable source of carbon materials, carbon-based electrodes for new-generation metal-ion batteries could be a more eco-friendly replacement for lithium-ion batteries. Some of the methods to make these compounds currently available are problematic because they require dangerously high temperatures and pressures and hazardous chemicals, but new methods are being developed which use mechanical forces instead. If these compounds can be developed into renewable sources for electronics, Dr Javier Quílez-Bermejo and his team at the Université de Lorraine point out, the potential for revolutionizing electronic devices would be huge, opening the way for greener fuel […]

New walking robot design could revolutionize how we build things in space

By Suzanna Burgelman, Frontiers science writer Image: Shutterstock.com Researchers have designed a state-of-the-art walking robot that could revolutionize large construction projects in space. They tested the feasibility of the robot for the in-space assembly of a 25m Large Aperture Space Telescope. They present their findings in Frontiers in Robotics and AI. A scaled-down prototype of the robot also showed promise for large construction applications on Earth. Maintenance and servicing of large constructions are nowhere more needed than in space, where the conditions are extreme and human technology has a short lifespan. Extravehicular activities (activities done by an astronaut outside a spacecraft), robotics, and autonomous systems solutions have been useful for servicing and maintenance missions and have helped the space community conduct ground-breaking research on various space missions. Advancements in robotics and autonomous systems facilitate a multitude of in-space services. This includes, but is not limited to, manufacturing, assembly, maintenance, astronomy, earth observation, and debris removal. With the countless risks involved, only relying on human builders is not enough, and current technologies are becoming outdated.  “We need to introduce sustainable, futuristic technology to support the current and growing orbital ecosystem,” explained corresponding author Manu Nair, PhD candidate at the University of […]

‘I got front row seats to the astronomy event of my lifetime, and it didn’t disappoint’

By Colm Gorey, Frontiers science communications manager/Dr Susan Mullally, STScI Image: Dr Susan Mullally, STScI The successful launch of the James Webb Space Telescope earlier this year captivated the world’s attention, promising a revolutionary view deep inside our mysterious universe. One of those involved in the hugely important project was Dr Susan Mullally of the Space Telescope Science Institute who now speaks to Frontiers about the once-in-a-lifetime opportunity. Last month, a new chapter in humanity’s understanding of the cosmos began when the first images taken by the James Webb Space Telescope (JWST) were released to the world. Surpassing the capabilities of the Hubble Space Telescope, JWST will directly observe a part of space and time never seen before and will gaze into the epoch when the very first stars and galaxies formed, more than 13.5bn years ago. Dr Susan Mullally of the Space Telescope Science Institute (STScI) was among those with backstage access to this latest piece of space history, and is currently the deputy project scientist for JWST working to ensure the scientific productivity of the mission. Previously, she worked in the Mikulski Archive for Space Telescopes (MAST) as the lead for archiving the data from NASA’s Transiting Exoplanet […]

Building blocks for RNA-based life abound at center of our galaxy

By Mischa Dijkstra, Frontiers science writer Scientists here study the spectra from G+0.693-0.027, a molecular cloud near the center of the Milky Way. They detect a range of nitriles, key building blocks for RNA, including cyanoallene, propargyl cyanide, cyanopropyne, and possibly cyanoformaldehyde and glycolonitrile, none of which had previously been found in G+0.693-0.027. They conclude that nitriles are among the most abundant chemical families in the universe, which lends support to the ‘RNA world’ theory of the origin of life on Earth, and possibly elsewhere in our galaxy. Nitriles, a class of organic molecules with a cyano group, that is, a carbon atom bound with an unsaturated triple bond to a nitrogen atom, are typically toxic. But paradoxically, they are also a key precursor for molecules essential for life, such as ribonucleotides, composed of the nucleobases or ‘letters’ A, U, C, and G, joined to a ribose and phosphate group, which together make up RNA. Now, a team of researchers from Spain, Japan, Chile, Italy, and the US show that a wide range of nitriles occurs in interstellar space within the molecular cloud G+0.693-0.027, near the center of the Milky Way. The results are published in Frontiers in Astronomy and […]

Method used to track ants underground could revolutionize how we measure snow depth from space

By Simona Pesce, Frontiers writer Photo of snow taken by crew of the International Space Station. Image: NASA With the help of some ants, NASA scientists have developed an innovative concept to measure exactly how deep the snow layer is covering sea ice and mountains using a lidar (Light Detection and Ranging) instrument in space. The findings, published in Frontiers in Remote Sensing, reveal this new method will have several applications and provide more accurate measurements on the evolution of snowpack as a result of the climate crisis and better monitoring of water resources globally. Ants may be the unlikely heroes when it comes to better understanding the health of our planet in the midst of a climate crisis. In a paper published to Frontiers in Remote Sensing, a team of scientists, including those from NASA, have found a way to estimate the depth of snow from orbit using ants deep underground. One member of the team is Yongxiang Hu from NASA’s Langley Research Center who drew inspiration from physics and biology to create a unique snow depth model. A previously developed model found that the average time an ant walks around inside the colony before coming back is roughly […]

Solar energy is superior to nuclear for powering crewed mission to Mars, show scientists

By Peter Rejcek, science writer A crewed mission to Mars will require transporting equipment for creating electricity to power life support systems. The choice for the type of device used will require a tradeoff between mass and energy efficiency. Researchers here show that a photovoltaic system using compressed hydrogen energy storage can compete with nuclear energy across about 50% of the Red Planet. No other planet in our solar system has sparked the human imagination more than Mars. While modern science has debunked the Red Planet as a likely source of an alien invasion, today’s technology is bringing us closer to a crewed mission. A research team out of the University of California, Berkeley published a paper in the journal Frontiers in Astronomy and Space Sciences that argues a human expedition on the surface could be powered by harvesting solar energy. The concept is not new. The main source of power for some NASA Mars rovers comes from a multipanel solar array. But, in the last decade or so, most people had assumed that nuclear power would be a better option than solar energy for human missions, according to co-lead author Aaron Berliner, a bioengineering graduate student in the Arkin […]
