  The Material Science Behind A Spacecraft's Impact Armor

  By Andy Tomaswick - May 08, 2026

  Aerospace engineers have to consider numerous factors when designing a spacecraft, but one that comes up more and more often is the need to design against Micro-Meteoroids and Orbital Debris (MMOD). While most designers understand the threat, designing structural solutions capable of withstanding the hypervelocity impacts these undercontrolled pieces of material can cause can take a significant bite out of a mission’s mass budget. A new paper from Binkal Kumar Sharma of the University of Bremen and Harshitha Baskar, an independent researcher, provides a detailed review of cutting-edge options for defending against those deadly particles.

  A New Way to Plan Trajectories to Asteroids

  By Andy Tomaswick - April 30, 2026

  There are tens of thousands of Near-Earth Objects (NEOs) that represent some of the most easily accessible resources in the solar system. If we can get to them at least. Planning trajectories to rendezvous with these miniature worlds is notoriously difficult, and requires a massive amount of computational power to calculate. But a new paper from astrodynamicist Alessandro Beolchi of Khalifa University of Science and Technology and his co-authors offers a much less computationally intensive way to find these trajectories, and has the added bonus of finding the much less energy-intensive paths to boot.

  Laser-Swarm Science at the Proxima Centauri System

  By Evan Gough - April 29, 2026

  The idea of sending a swarm of tiny laser-sail powered spacecraft to our nearest exoplanet won't go away. While complex and punctuated with tough problems, the idea is the only realistic way of reaching another solar system this century, according to researchers. But the scientific benefits would be huge.

  To Survive Deep Space, Astronauts May Owe a Debt to Microscopic Worms

  By Andy Tomaswick - April 17, 2026

  Living long-term on the Moon means surviving the devastating toll that deep space takes on a human body. Astronauts in low gravity environments suffer muscle and bone loss, vision-altering fluid shifts, and heavy radiation exposure - all of which are incredibly hazardous to our biology. So, to help future lunar explorers survive, a new crew just arrived at the International Space Station (ISS). That might not sound surprising, except this crew is composed of worms.

  A New Study Narrows the Search for Water on the Moon

  By Matthew Williams - April 13, 2026

  A new study challenges old assumptions by revealing that water on the Moon likely came from multiple sources over billions of years, rather than from a single major deposit long ago.

  ESA Launches 7 New Missions to Supercharge Space Data Transfer

  By Andy Tomaswick - April 10, 2026

  Space is getting crowded - and not just with satellites, but with the massive amounts of data they’re generating. The amount of information being generated and passed through orbit is exploding. From high-resolution Earth observation images to global maritime monitoring, it’s also become a critical link in our infrastructure. But there’s another space this growing crowd of satellites is dependent on that is also filling up fast - the radio frequency spectrum. If we want to keep expanding our orbital infrastructure, we need to rethink how we move data around. On March 30, 2026, the European Space Agency (ESA) supported a series of eight CubeSats and one specialized payload on SpaceX’s Transporter-16 rideshare mission with the overarching goals of testing high-throughput laser communication, inter-satellite networking, and in-orbit artificial intelligence processing to make space data transfer faster, more secure, and vastly more efficient.

  Meet Orpheus - A Hopper Mission Built To Hunt For Life In Martian Volcanoes

  By Andy Tomaswick - April 08, 2026

  We’ve spent decades scratching the surface of Mars trying to uncover life there. But we’ve been searching a barren wasteland bombarded by radiation and bathed in toxic perchlorates. The entire time, it's likely that it’s been too hostile to harbor extant life. So if we want a better shot at finding currently living life on Mars, we need to go underground. That is exactly the purpose of Orpheus, a proposed Mars vertical takeoff and landing (VTOL) hopper mission put forth by Connor Bunn and Pascal Lee of the SETI Institute at the 57th Lunar and Planetary Science Conference (LPSC).

  JAXA Plans To Bring Back Pristine Early Solar System Samples From A Comet

  By Andy Tomaswick - April 07, 2026

  Japan’s space agency, JAXA, has been knocking it out of the park with small-body exploration missions for decades. They had historic successes with both Hayabusa and Hayabusa2, and they are going to visit the Martian Moons soon with the Martian Moons eXploration (MMX) mission. But after that, they are aiming for something much more pristine and arguably more difficult - a comet. The Next Generation Small-Body Return (NGSR) was recently described in a paper at the Lunar and Planetary Science Conference (LPSC), and is under assessment as a large-class mission for the 2030s.

  Mercury Scout Mission Concept with Solar Sail Propulsion

  By Laurence Tognetti, MSc - April 01, 2026

  The planet Mercury is the closest planet to the Sun, and also the most difficult for spacecraft to visit and explore. This is because as spacecraft get closer to Mercury, the Sun’s enormous gravity pulls in the spacecraft, greatly increasing its speed and making it hard to slow down without large amounts of fuel. But what if a spacecraft could both travel to and explore Mercury without fuel? This could drastically reduce mission costs while delivering impactful science.

  KYTHERA Mission Concept Targets 200-Day Mission to Venus Surface

  By Laurence Tognetti, MSc - April 01, 2026

  The planet Venus is often called “Earth’s twin” due to the similar sizes, but the reality couldn’t be farther from the truth. Unlike Earth, which is hospitable to an estimated billions of lifeforms, Venus is not hospitable to life as we know it, at least on its surface. This is because the surface of Venus not only experiences an average temperature of 464 degrees Celsius (867 degrees Fahrenheit), but it also has crushing pressures approximately 92 times of Earth, or equivalent to approximately 1 kilometer (3,000 feet) below the ocean. These extreme surface conditions are why the longest spacecraft to survive on the Venusian surface is just over two hours.

  Uranus Mission Concept CASMIUS to Probe Ice Giant Secrets

  By Laurence Tognetti, MSc - March 31, 2026

  The ice giant Uranus is one of the most fascinating objects in the solar system, with its sideways rotation, intricate ring system, and unique family of moons. However, it is also one of the least explored objects in the solar system, owing to its extreme distance from the Sun. With NASA’s Voyager 2 spacecraft remaining as the only spacecraft to visit Uranus, scientists continue to design and envision mission concepts for returning to explore Uranus and its icy secrets.

  Hera Aces A Massive Engine Burn On Its Way To Didymos

  By Andy Tomaswick - March 27, 2026

  In September 2022, humanity crashed a spacecraft into an asteroid - on purpose. The objective of NASA’s Double Asteroid Redirection Test (DART) was to see if we could intentionally modify the orbit of Dimorphos, the small moonlet orbiting the larger asteroid Didymos. According to all accounts, the mission worked spectacularly, but it was a one-way trip, so our ability to see what happened to the binary asteroid system has so far been limited to ground-based telescopes. That wasn’t good enough for the planetary defense community, so they planned a follow up mission called Hera, which, according to a recent press release from its operator, the European Space Agency (ESA), just successfully completed its most dramatic deep-space orbital maneuver.

  Spacecraft Heat Shields Could Violently "Burst" When Plunging Into Alien Atmospheres

  By Andy Tomaswick - March 24, 2026

  Heat shield design is one of the most critical aspects of missions that plan to either land on a planet’s (or moon’s) surface or return to our own. Spacecraft that have to survive the fiery, hypersonic plunge through an atmosphere require these systems. For decades, heat shields have been designed to slowly burn away in a process called ablation, which is intended to dissipate the incredible thermal energy or reentry. But, there’s another, less understood phenomenon that affects them too - spallation, where a heat shield sheds material in violent, unpredictable “bursts”. This second mode of destruction seems to be particularly prevalent in oxygen-deprived atmospheres, like that of Titan, where the Dragonfly helicopter plans to land in the not too distant future. A new paper published in Carbon from researchers at the University of Illinois Urbana-Champaign (UIUC) performed some tests showing just how different those heat shields might need to be.

  JUICE is Planning To Do Science On Jupiter's "Minor" Moons Too

  By Andy Tomaswick - March 19, 2026

  The European Space Agency’s (ESA’s) Jupiter Icy Moons Explorer (JUICE) probe is on its (very long) way to Jupiter, and will finally arrive at the King of Planets in 2031. Its primary mission is to focus on the “big three” icy moons - Ganymede, Europa, and Callisto. But while JUICE is busy mapping Ganymede’s magnetic field, it will also be keeping a sharp eye on the other 94 moons in the Jupiter system. A recent paper published in Space Science Reviews by Tilmann Denk of DLR, Germany’s space research association, and his co-authors showcases just how much “bonus science” JUICE is expected to squeeze out of these other targets.
