On the surface (you're welcome for the joke), Venus is not even close to being hospitable to life. But that's not the end of the story.

Chinese rocket startup Space Epoch put on a show recently, with a demonstration test launch of their reusable Yanxinghe-1 rocket booster.

Mars is by far the most Earth-like planet in the solar system…but that's not saying much.

In a recent paper, UCSB physicist Jack Kingdon identified a trajectory for a rapid transit (90 days) to Mars using SpaceX's Starship. This proposal offers an alternative to mission architectures that rely on nuclear propulsion to reduce transit times.

The challenge in the search for habitable worlds is clear. We need to be able to identify habitable worlds and distinguish between biotic and abiotic processes. Ideally, scientists would do this on entire populations of exoplanets rather than on a case-by-case basis. Exoplanets' natural thermostats might provide a way of doing this.

The idea that the Milky Way (MW) and Andromeda (M31) will collide emerged after decades of observations by a host of astronomers. The Hubble played a decisive role in the determination during the early 2000s. It was a triumph of precision astronomy and space telescopes. Now, the Hubble has played an equally important role in cancelling the collision.

How can humanity use the developing Lunar Gateway as an appropriate starting point for advancing human space exploration beyond the Moon? This is what a recent study presented at the 56th Lunar and Planetary Science Conference (LPSC) hopes to address as a team of researchers evaluated a myriad of ways that Lunar Gateway could be used as a testbed for future technologies involving sending humans to Mars and Ceres. This study has the potential to help scientists, engineers, astronauts, and mission planners develop novel strategies for advancing long-term human space exploration.

The search for life on other worlds needs a way to sift through the chemistry of their atmospheres. If another species observed Earth to search for life, they'd look for "smoking gun" chemistry in the atmosphere. That includes looking for oxygen, since it is created through photosynthesis by plants and some bacteria. So, the key is to look for life-dependent chemical "signals" at exoplanets.

Solar storms have the potential to cause catastrophic damage. One that occurred around the end of October 2003 (now called the 2003 Halloween Storm) caused an estimated $27B in damages. That number will only increase as humanity has become more reliant on space-based and electrical infrastructure. However, if we could predict when storms would hit with some accuracy and adjust our use of the technologies that could be affected, we could avoid the worst damage. But, as of now, we don't have such a system that could help predict the types of events that could cause that damage accurately enough. That is where a new Sun activity monitoring system, described in a recent paper by Leonidas Askianakis of the Technical University of Munich, would help.

How can fission-powered propulsion help advance deep space exploration, specifically to the outer planets like Jupiter, Saturn, Uranus, and Neptune? This is what a recent study presented at the 56th Lunar and Planetary Science Conference (LPSC) hopes to address as a pair of researchers from India investigated the financial, logistical, and reliability of using fission power for future deep space missions. This study has the potential to help scientists, engineers, and future astronauts develop next-generation technologies as humanity continues to expand its presence in space.

The grainy videos from the Apollo Moon landings are treasured historical artifacts. For many of us, that footage will be lodged in our minds until our final synaptic spark sputters out. But like all technology since the space race days, video technology has advanced enormously, and the next Moon landings will be captured in high-definition video. The ESA is so focused on getting it right that they're practicing filming lunar landings in a special studio that mimics the conditions on the lunar surface.

Not all Full Moons are created the same. Follow the familiar Moon long enough, and you'll notice something strange, as it seems to wander across the sky from north to south, from one cycle to the next. Welcome to the fantastic precession of our natural satellite the Moon. Last December, we saw the 'Long Night's Full Moon,' as the Full Moon nearest to the solstice rode the highest in the sky for the last two decades. Now, its time for the southern hemisphere to get a turn, as the Moon heads steeply southward, on its way to Full on June 11th.

In a universe of a billion galaxies, Earth is the world known to have life. If we're a common example of what happens in the Universe, then our location can tell us something about habitability. A new study is about to flip everything we thought we knew about habitability on its head, examining the potential for life in exotic environments, such as rogue planets, water worlds, and tidally locked planets, and calculate how habitable they would be compared to Earth. As we learn more about these other worlds, if they are more habitable, it can give new predictions.

Just when astronomers think they're starting to understand stellar activity, something strange grabs their attention. That's the case with a newly discovered stellar object called ASKAP J1832-0911. It lies about 15,000 light-years from Earth and belongs to a class of stellar objects called "long-period radio transients." That means it emits radio waves that vary in their intensity on a schedule of only 44 minutes per cycle. It does the same thing in X-ray intensities, which is the first time anybody's seen such a thing coupled with long-period radio transits.

You'd think that icy worlds are frozen in time and space because they're - well - icy. However, planetary scientists know that all worlds can and do change, no matter how long it takes. That's true for Europa, one of Jupiter's four largest moons. Recent observations made by the James Webb Space Telescope (JWST) zero in on the Europan surface ices and show they're constantly changing.

NASA's Mars Reconnaissance Orbiter is equipped with a powerful tool called SHARAD (Shallow Radar), designed to peer beneath the Martian surface and uncover hidden layers of ice, rock, and geological secrets. To accommodate it, engineers mounted SHARAD on the side of the spacecraft, requiring the orbiter to roll 28° during operation to boost signal quality. But computer models hinted at something else: if the orbiter rolled more than 120°, the radar performance could dramatically improve. Scientists put this daring idea to the test—and it paid off. The extreme roll manoeuvre worked, unlocking an even clearer view of Mars's buried past.

Betelgeuse is dying—but not quietly. This colossal red supergiant, already famous for its brightness fluctuations, has now revealed a strange long-term rhythm: a secondary pulse every 2,100 days. One tantalising theory suggests a hidden companion—possibly a second star orbiting Betelgeuse at roughly the distance between Saturn and the Sun, circling every six years. Astronomers recently pointed the Hubble Space Telescope at the giant in search of this elusive "Betel-Buddy" but failed to find it constraining its size and orbit.

Exoplanet science is shifting from finding any detectable exoplanets we can to searching for those in their stars' habitable zones. NASA's proposed Habitable World Observatory and other similar efforts are focused on these worlds. The problem is, habitable zones aren't static.

Frameworks are a critical, if underappreciated, component of any space exploration mission. They can range from the overall mission architecture, capturing scientific and technical goals, to the structure of messages sent between two internal components of the system. One of the most interesting frameworks that is getting much attention in the space exploration community is the interaction of multiple robots for a single purpose, known as a multiple-robot system, or MRS. On top of that, one of the most common frameworks for robots on Earth or in space is the open-source Robot Operating System (ROS), which is commonly used to run everything from vacuum cleaners to giant mining trucks. Its most recent iteration, ROS2, even uses yet another framework, known as a middleware, to handle aspects of robot communication such as networking and packetizing data. However, there are plenty of different middlewares to choose from for ROS2, so a team of researchers from the University of Luxembourg decided to try to pick one that would be best for planetary exploration applications.
