China has some bold plans for space research and exploration that will be taking place in the coming decades. This includes doubling the size of their Tiangong space station, sending additional robotic missions to the Moon, and building the International Lunar Research Station (ILRS) around the lunar south pole. They also hope to begin sending crewed missions to Mars by 2033, becoming the first national space agency to do so. Not to be left behind in the commercial space sector, China is also looking to create a space tourism industry that offers suborbital flights for customers.

The arrival of spacecraft on alien worlds uses a number of different techniques from giant air bags to parachutes and small rockets. The use of rockets can pose a problem to onboard technology though as the dust kicked up can effect sensors and cameras and the landing site can be disturbed in the process. A team of researchers have developed a new instrument that can measure the dust that is kicked up on landing to inform future instrument design. 

The source of Earth’s water is an enduring mystery that extends to exoplanets and the notion of habitability. In broad terms, Earth’s water was either part of the planet from the beginning of its formation in the solar nebula or delivered later, maybe by asteroids and comets.

Sending an object to another star is still the stuff of science fiction. But some concrete missions could get us at least part way there. These “interstellar precursor missions” include a trip to the Solar Gravitational Lens point at 550 AU from the Sun – farther than any artificial object has ever been, including Voyager. To get there, we’ll need plenty of new technologies, and a recent paper presented at the 75th International Astronautical Congress in Milan this month looks at one of those potential technologies – electric propulsion systems, otherwise known as ion drives. 

Neutron stars and black holes are the remnants of dead stars. They typically form as part of a supernova explosion, where the outer layers of an old star are violently cast off while the core of the star collapses to form the remnant. This violent origin can have significant consequences for both the remnant and the surrounding environment.

It was 1969 that humans first set foot on the Moon. Now, over 50 years later we are setting sights on building lunar bases. The ability to complete that goal is dependent on either transporting significant amounts of material to the Moon to construct bases or somehow utilising raw lunar materials. A team of Chinese researchers have developed a technique to create bricks from material that is very similar to the soil found on the Moon. The hope is that the lunar soil can in the future, be used to build bricks on the Moon.

Everybody knows that for life to thrive on any world, you need water, warmth, and something to eat. It’s like a habitability mantra. But, what other factors affect habitability? What if you relaxed the conditions conducive to life? Would it still exist? If so, what would it be?

One of the many threats facing space travellers and indeed our own planet is that of Solar Storms. At their most minor they can grant polar latitudes with a gentle auroral display but at their most extreme they can pose a threat to technology in space, communications and even our atmosphere. Now a team of researchers have found that extreme space weather can leave its mark in tree rings, leaving evidence that can help guard against future severe events. 

This stunning image of a star cluster in the Small Magellanic Cloud (SMC) is more than just a pretty picture. It’s part of a scientific effort to understand star formation in an environment different from ours. The young star cluster is called NGC 602, and it’s very young, only about 2 or 3 million years old.

Since the 1960s, astronomers have theorized that the Universe may be filled with a mysterious mass that only interacts with “normal matter” via gravity. This mass, nicknamed Dark Matter (DM), is essential to resolving issues between astronomical observations and General Relativity. In recent years, scientists have considered that DM may be composed of axions, a class of hypothetical elementary particles with low mass within a specific range. First proposed in the 1970s to resolve problems in the Standard Model of particle physics, these particles have emerged as a leading candidate for DM.

Some of the most cataclysmic and mysterious events in the cosmos only reveal themselves by their gravitational waves. We’ve detected some of them with our ground-based detectors, but the size of these detectors is limited. The next step forward in gravitational wave (GW) astronomy is a space-based detector: LISA, the Laser Interferometer Space Antenna.

Nestled on the slopes of Cerro La Negra at an elevation of 13,000 feet is an unusual-looking observatory. Known as the High-Altitude Water Cherenkov (HAWC) observatory, it looks like a tightly packed collection of grain silos, which is essentially what it is. But rather than holding grain, the silos are each filled with 188,000 liters of water and four photomultiplier tubes. While it’s an unusual setup, it’s what you need to observe high-energy gamma rays from deep space.

Between 2011 and 2018, NASA’s Dawn mission conducted extended observations of Ceres and Vesta, the largest bodies in the Main Asteroid Belt. The mission’s purpose was to address questions about the formation of the Solar System since asteroids are leftover material from the process, which began roughly 4.5 billion years ago. Ceres and Vesta were chosen because Ceres is largely composed of ice, while Vesta is largely composed of rock. During the years it orbited these bodies, Dawn revealed several interesting features on their surfaces.

Testing is one of the unsung steps in the engineering process. Talk to any product development engineer, and they will tell you how big of a milestone passing “V&V” – or verification and validation – testing is. Testing is even more critical when you work on equipment meant for the harsh space environment. It is also more challenging to mimic those harsh environments on Earth. Luckily for some of NASA’s more critical upcoming missions, another government agency has a unique test lab to help V&V with some of its most critical components – their heat shields.

Most of us know about the impact that wiped out the dinosaurs about 66 million years ago. It’s a scientific fact that’s entered mainstream knowledge, maybe because so many of us shared a fascination with dinosaurs as children. However, it’s not the only catastrophic impact that shaped life on Earth.

With ‘Thousand Sails,’ China joins the race to fill up Low Earth Orbit with mega-satellite constellations.

The word “volatile” is commonly used in the space exploration community, but it has a different meaning than when used otherwise. In space exploration, volatiles are defined as the six most common elements in living organisms, plus water. Earth had enough volatiles for life to start here, but it might not have been that way. Researchers from the University of Cambridge and Imperial College London now think they have a reason why Earth received as many volatiles as it did – and thereby allowed it to develop life in the first place.

The elliptical galaxy NGC 1270 lies about 240 million light-years away. But it’s not alone. It’s part of the Perseus Cluster (Abell 426), the brightest X-ray object in the sky and one of the most massive objects in the Universe.

Ships passing in the night used Morse code sent with lanterns and shutters to communicate. That same basic principle has allowed NASA to communicate with Psyche, its mission to a metal-rich asteroid in the main belt. However, the “light” was a version of heat, and instead of being able to see each other, Psyche is 240 million miles away from Earth. Oh, and the upload rate of the data it sent is still better than old dial-up internet connections that were prevalent not so long ago.

The massive South Pole-Aitken (SPA) basin is one of the Moon’s dominant features, though it’s not visible from Earth. It’s on the lunar far side, and only visible to spacecraft. It’s one of the largest impact features in the Solar System, and there are many outstanding questions about it. What type of impactor created it? Where did the ejected material end up? Is it feasible or worthwhile to explore it?

In this decade and the next, multiple space agencies will send crewed missions to the Moon for the first time since the Apollo Era. These missions will culminate in the creation of permanent lunar infrastructure, including habitats, using local resources – aka. In-situ resource utilization (ISRU). This will include lunar regolith, which robots equipped with additive manufacturing (3D printing) will use to fashion building materials. These operations will leverage advances in teleoperation, where controllers on Earth will remotely operate robots on the lunar surface.
